The Mid Bike Chronicles of A Mad Man

[The Nutty Professor]

Where to begin? We are all officially nuts speechless33 ! I haven’t been on a bike in a while so I was taking it a little easy through the first go around the block. My neighborhood is somewhat closed off and it’s normal working hours so traffic is about non-existent...but I’m jumping ahead of myself. I got up this morning and of course changed my regular routine because I had someone waiting on me in the garage. I backed momma’s van out and pushed “TN” to the middle of the floor and pulled out the tools I thought I would need. Of course I only ended up with half the total I really needed. I cussed every time I went back to the tool box. I can’t figure out how the Chinese think when they make these bikes. If the rear axle nut is 17mm then why isn’t the head of the axle 17mm? Why is it 14mm? My CBR was 17 and 17. The Japanese way makes a hell of a lot more sense to me, but then again they did learn to build that way from the good old U.S. OK I have to admit to being ignorant about something. I checked the oil and loosened the chain I checked the tire pressure in the rear (Notice I didn’t say the front Dee Dee Dee!). The oil actually looked half decent and it even smelled like oil ;) so I left that alone for now. Then I added some gas to the tank. Moved the controls to the place they felt the best and tightened them down. Unplugged the battery and checked the lights and horn (That thing is the first to go). Then pushed down on the forks again and shook my head. Then I went to fire her up and did the usual check. It’s hard getting her into the right gear sitting on her at a stop so I reached do and changed it by hand watching the gear indicator. Which I suspect shows the gear you were in five changes ago. Any way when there was no indication she was in gear I turned on the ignition and pushed the start button...nothing. I checked over everything and tried again...nothing. I sat back and went through the mental checklist and I couldn’t figure out what I was doing wrong. Ok I’m not normal I read maps when I’m not sure were I am, I ask directions, and I read through the instruction manual as soon as I have a problem. Those Chinese pieces of paper ain’t what I would call a manual though. I flipped through straight to the start procedure and DAMN there was something I would not have thought the Chinese would add to anything. A little bite of safety to a product!!!!! As you start the bike you have to hold in the rear brake lever. Just like starting a 1:1 except they have numerous combination of built in safety’s. OK now she’s running. I get off the seat and walk around looking for leaks or pieces dragging. She starts smoking from the pipe and under the bodywork. OK she’s been sitting probably for months and some oil has leaked down. Not a problem. There’s probably some oil or grease on the header that’s the smoke from the bodywork area. Both assessments seem to hold true because after warming up the pipes stop smoking and after a little more time the smoke from under the bodywork stops. OK riding time. Put on my helmet and some gloves and drive her out of the garage. Do a spin in the circle. She steering funky on the front. Hey she’s new I’ll figure out the steering in a minute. Then I start down the street and attempt a shift. I don’t like semi-auto. I wanted to grab the rear brake lever as I was shifting but I didn’t. I had to mentally remind myself that I only needed to shift with me foot. Then shifting was a torture on my senses. I haven’t gotten the hang of it yet and the clunk in the transmission sent chills up my spine. I would try speed shifts, and dropping the rev’s shifts, and slow and easy shifts. They all sounded and felt the same. There was one exception last speed shift I had it pinned in 3rd and I shifted. The front end came up about 2 inches dropped down and just kept pulling. Nice. The one thing that brought me back to reality was the fact that I started looking ahead down the road and could see how fast I was coming up to corners. I knew if a driver stopped at the sign and looked he might not see me and I was movin’! Riding a pink Razor scooter and a Mid are 2 big different animals. The road goes by a hell of lot quicker on a Super Mid. No more riding on the street unless I’m riding next to my little hellraiser. She’ll slow me down to her speed. Oh the front tire! 20psi of air in a front tire sure makes for strange handling! I’ve done this before so I really should have known what it was but hey? The forks suck and the brakes feel like wood. These things are way way under braked (?) for the speeds they can achieve. Forks and brakes and my next must. If I’m going to be ready for the Mid Bike Summer Fling. But after this ride I’m more convinced that displacement isn’t the king of racing Mid’s it’s gearing. Yes there is no replacement for displacement but a properly geared 114cc high comp would stomp on a 125cc maybe 138cc “I run what gearing I had” bike. By that I also mean close ratio gears in the trans and sprocket gearing. Just my twocents on that one. Ok enough talking I’ve got riding to do. I have to get her set for The Isle of Nutt TT course...To Be Continued

[mishka]

Good to see it running!
ya the suspension on these bikes aren't that good.
i dont really mind it but the rear wheel sometimes hopes,
or skips when ur turning. so watch out for that...
you should take some better pictures of the bike and
post some pictures on here!
ive never seen any good looking pictures of the 22'
but ya good luck with the suspension, cant wait to
see what you have planed for the bike!thumbsup2

[rednek01]

Man I am so jealous!!! I'm about to explode!

[The Nutty Professor]

Man I am so jealous!!! I'm about to explode!

Do that and you can't ride later. Hang tough it's coming.

[rednek01]

Do that and you can't ride later. Hang tough it's coming.

Haha good point I just know its going to be worse after I put the actual order in because than I know its coming banghead

[stuntnx7]

i didnt even know i was gettin mine. One of my friends bought it for me on my B-day when i was 18.....i remember i was lookin at it online bcuz i just now heard about the 110cc r1 and then he pulled up with my dad and my dad was like look at the new toy he bought so he dont have to walk around pits.....i had no clue it was mine then he said get this thang outta my van and go ride your new bike....i was trippin when he said dat.....i had a slooowwww x1 43cc before then....it ran 20.0's in the 8th at 26 most of the time.....lol...sometime it ran 21's...lol...never consistent but i won a bunch on that terd

[The Nutty Professor]

I’ve had the bike less than a day and I’m already modifying it. Hell I knew I would but even I though I would hold out a little longer. On my first write up I was complaining about the shifting, well I still don’t like the system but I’ve figured out the up shift. Aggression is the key. Playing around gets you a clunk. Caning the piss out of it and flicking the throttle off as you shift and slapping it back to WFO gave me seamless shifts. What I don’t like is the revs fall off and with these bikes you have to keep them up or at least this bike you do. I also don’t like the fact that I can’t free-wheel through a corner. Well I rode back into the garage to see what I could do about the shift lever. Looking at the arm that clamps onto the shifter I could see I would have to take off the bodywork to get at it. I looked at which screws I would have to remove first and saw the screws in the bellypan as the first set. If you remove the left or the right-side first the panel screws on the other side stress the plastic at the mounting points. Take it apart at the middle and then each side is held up by the weight of just the one panel. Any way removing those three screws was a stone (female dog). I knew have to do that to many times would get old and probably crack the panel somewhere. I sat back and thought for a minute and started rummaging through my nuts and bolts. Damn forgot about these! I have had a bunch of aircraft quick-release fasteners for years. I tried using them on my race bike but they were to small. Now they were just right. Everywhere a panel met a panel I put a quick-release (Still have a couple to go). The back half of the fastener has riveted to the panel but I don’t have one so I just locked them together. They’ll stay in place but when I take them apart the back will fall. The front of the fastener is held with a coupling washer which I have a lot of. OK the bodywork is finished so on to the shifter. Want to talk about huh (?) moments. I looked at the shifter after taking it off and I could see it was bent and twisted. OK break out the BFH. I put it in the vise and started whacking on it hoping it won’t break. 30 minutes of smacking and fitting and sitting and shifting I got it as good as it’s going to get. Then I had my first bolt mash it’s threads. I tried putting the bolt back in and it was a no go. OK back to the bolt box. Had a bolt back in about 2 minutes later. After getting this done I started looking over the bike. First thing I noticed was no airbox. There was a pod filter on the carby. I then looked at the exhaust header to see how it was put together and found the EPA’s hand on my bike. There was an emission system attached to the header. Not a problem it’s simple and just attaches at the one spot. Horn first emissions second. Anybody else have footpegs that don’t have a spring that pushes the peg back down. I’ve flipped it up more than once by accident. Either a solid of pegs or springs are in the near future. Rearsets are a little ways out...To Be Continued

[The Nutty Professor]

In these you can see the header looking like spaghetti. The shifter I wailed on and the quick-releases on the side panels. More coming.

[schofell84]

bahaha that pipe looks horrendous, and the filter is almost not even there its so small. im willing to bet with a good filter and pipe you'd see some surprising gains. the quick releases look nice, theyre always good to have. have fun with yours, i wont have one until i sell my bike and car.angry_red

[The Nutty Professor]

It just surprised me it had a pod at all. Yeah that exhaust is one for the books. One thing I found out I would like to change is the swingarm is open beam. I thought it was closed up? I bet when I start pushing it's going to flex. Oh well it looks easy to fix though.

[schofell84]

just gonna box it in? if you really wanted to get high tech you could shot peen it haha

[Blitz$M.Inc.$]

ya those quick disconnects are in my bikes future
take your body panels and get them molded for carbon fibre before they break, wouldnt that be sweet
i wonder how mush a fairing set would cost to do

[redryderaus]

That exhaust is a joke and a bad one at that. That would be the first thing to go if it was me. Looks like they got a furniture maker to bend the pipe. It's crimped down to buggery and those sharp bends will slow the gases almost to a standstill.

Cheers,

[swheels]

Yeah that exhaust and airfilter is a gotta go item.What i about the rake on the bike.Do you plan on changing it?When i saw the bike in person i thought the rake was rather steep.Man i can't wait till we can get out there and rip up some track.Although i consider us team mates i'm still your competitor.LOLSo i'll be watching you.speechless33

Here's one for ya.I almost bought the megasquirt but opt out at the last minute for parts i really needed and so far my parts haven't showed up YET! There killing.

[swanni06]

where can a person buy those fasteners? Know what size they are and what they would listed as?

[schofell84]

those fasteners can be had at any good hardware store.

[stuntnx7]

my friend might could make a carbon fiber body for these....i told em he should but we never talked about it anymore

[swanni06]

those fasteners can be had at any good hardware store.
well I am in canada lol sobanghead...what name do I look under if I have to ask where they are

[schofell84]

something to do with quick release haha ... nutty should know the actual name.

[redryderaus]

They're known as "quick release", "1/4 turn" and "De zeus" fasteners amongst others. They have a bit of wire that fixes to the part you want to hold something to. The fastener part has a shaped slot in the end and goes through the part you want to hold in place and fits over the wire. 1/4 turn CW and it locks onto the wire.

Cheers,

red

[swanni06]

cool..thanks guys

[The Nutty Professor]

The fasteners where given to me by a friend who works on military helicopters. The model with the 2 rotors on top. I forget what they call it. I’ve been off here for a couple hours because I was waiting on a friend to deliver a Kawasaki he was giving away so he gave it to me. 1992 Kawasaki ZX-6R. Not the real supersport model the lower grade model. So while I was waiting I started working on “TN” again. I couldn’t decide where to start so I went to the offside muffler and removed it. I then started the bike without one muffler. Guess what? It didn’t sound much louder. Second muffler does get some work but not enough to matter. But I’ll keep it it will be my one concession to looks over race function for now. Then I started to take the pipe apart to see how I could get rid of some of the restriction. I drilled out the rivets and pushed the center out...boy what a piece. Look at the photo. The dents in it were there when I pushed the core out. A rusted dented drainpipe. The weld looks like one of mine. For now I plan to keep the shell and the two end caps and put together a core from another pipe. It will work until I can find the parts for my carbon titanium pipe. I have most of the stuff I just need two 4 x 12 inch carbon fiber tubing. I also rode the bike outside after dark and who the hell said you can ride these at night! The tail-light, at least on the X22, is a single filament bulb. So it’s NOT a tail-light it’s a brake-light only. The headlight is for people to see you because it sure doesn’t put out enough light to see anything in the road. If you plan on tagging your ride you better invest in some lights if you want to live through a ride home in the dark. I think I have a tank venting problem. I was riding the bike and she rode fine. Then I turned into the driveway and she started running rough. Then she shut off. I started her she ran for a couple seconds and shut off. I thought hmmm out of gas? I almost filled the tank the last time it couldn’t be out. I shook the bike from side-to-side to see if I could hear gas. I could so I removed the gas cap and shook her again. Plenty of gas. I put the cap back on and she fired up and kept running. Now I have to tap the cap and run a vent line. If there’s already one it’s kinked or not right. Either way a second line that I know works is better insurance. To Be Continued

[redryderaus]

The helicopter is the Chinook. Another famous Vietnam vet along with the Huey :) . I wish one of my friends would give me a '92 ZX-6R. From your description it sounds like what is sold as a ZZR-600 here. Still a darn good bike. Same engine, just detuned with smaller carbys, milder cam and heavier pistons.

I'd be putting that muffler in the same place as the rest of the exhaust. That place is known as the "round filing cabinet" aka the rubbish bin. That thing looks like copper sheet rolled and soft soldered together.

I made my own carbon tube for a muffler. Believe it or not it's not that hard to do. I can feel another pictorial How-To coming on thumbsup2 . I'll have to see if I can dig up the mould I made to do it. The mould is made from some PVC drainpipe, three plywood discs, some 10mm threaded rod, six 10mm nuts and some plastic sheet you can pick up at any building supplies store or a gardening store (your famous Walmart would probably have it). It is easily made with fairly basic tools. Carbon cloth is readily available from fibreglass supply stores as is the epoxy resin, mould release, etc.

[The Nutty Professor]

No what looked like copper was rusted steel speechless33 there was water between the aluminum sleeveand the steel pipe insert. I have carbon cloth already. I was looking at a pre-made tube for the speed and the fact I don't think I can get a decent exterior finish. I started my interest in motorsports with Formula 1. They believe in function over form, but you should still look good doing it bluelaugh That's how I gauged myself on my first port/polish job if it didn't look good it wasn't right. 4 weeks later I had a head that was right.

[rednek01]

That pipe just looks plain grosswave_finger I wonder if my buddy at the muffler shop will let me use his tube bender to make an exhaust for my bike once I get it. If so maybe I could start making exhausts for these bikes and selling them.

With my method you get an excellent finish. Trust me, I'm the bloke selling the Golden Gate bridge to swheels rofl Oh, hang on, I shouldn't have said that......

Seriously, you do get a great finish, that's what the plastic sheet is for. But it may be quicker to just buy a carbon tube than wait for a how-to. My to-do list ain't getting any shorter at the moment.

asian concepts has a line of rearsets! we gotta find someone to buy their stuff through!There on ebay selling them.But the price whew.I gotta get of my lazymoon1 and start making them.Theres no place where i live that sells aluminum stock.And with certain materials i like to pruchase in person rather than order.

[55IsABigLie]

From the moment X18Pocket took his body off to custom paint it, I've been chewing his ear off how we just need to replace those horrid nut/bolts with some decent cotter pins or something for racing. Pull the whole body off in 7 seconds.

X18Pocket left 2 bolts and industrial velcroed the rest- and because the way everything pushes into everything else it holds quite well..(yes, you may stop laughing now! machinegun).

I'm with the Nutt on this- where can I get those fasteners? I get *real* annoyed when I can't tinker with sh*t easily. banghead

Hey Nutty!
Do your grips look anything like this???
Saw these on happyscooters on the same kind of bike you got.
I like the look of these grips and would like to get my grubby hands on a pair of these..........if anyone out there's got any anywheredunno

No they don't. I don't have a close up of them but I'll put one up. They ain't that bad they actually help with throttle action.

[The Nutty Professor]

I didn't have much time with the bike today. It was a family day. I continued working on the pipes and almost threw the parts through the garage wall. I cut the end caps off after a lot of grinding and cussing. The welds were worse than mine and I've only been welding since December when I got a welder for X-Mas. I pulled out the core and thought about cutting it open to see what I had been dealing with. I decided not to because I was already in shock over the poor quality so far. I know I shouldn't expect more than what I've been seeing, but if I worked in a factory I couldn't live with myself it I put out work like that. I also know they probably work by piece profit but the welds are big and ugly so making a better weld would probably be faster? After this little experience I would say unless you have a lot of raw parts (I have a lot of 1:1 pipes to steal stuff from) don't try to make a pipe. Yes you can gut a pipe and go but most motors need a little back pressure to work right. Find a pipe you like and can afford and go with that. Spend your time fabricating parts that are harder to find. Just my twocents Oh and Blitz I now understand what you meant by not needing a hairdryer to remove the stickers. I used my fingernail to pull up the edge and the stickers peeled off like they where painters masking tape. Another cheap add on, but a good cheap one. Makes for less work. To Be Continued

[The Nutty Professor]

I have a question for some of you professional welders out there. I just took two pieces of titanium and welded them together using my Mig welder. I then attempted to break the weld and it wouldn't break. A second weld I did broke but that was because the wire made up the weld itself. On the other weld the titanium melted and fused into the other melted piece. I would use this as a structural weld but I'm using it to weld pieces in side a pipe. My question is will it hold? The way I'm putting the pipe together it really doesn't matter but I'm just curious. I'll post how I put it together and what I used. I'm kind of surprised with myself on this one.

[redryderaus]

What wire did you use to weld the titanium? As a rule the wire you use should always be as close to the metal you are welding as possible.

Two things will break a weld. First and most obvious is structural stress. Second is fatigue. That fatigue will most often come from either vibration or a continual flexing of the welded area. As long as the welded area is supported then it shouldn't be an issue.

Cheers,

red

[schofell84]

i thought you can only tig weld titanium?

[redryderaus]

It can be mig welded, though tig is preferred. I've never tried to weld it, but I've seen it done. In either case the metal should be annealed after welding as titanium becomes brittle at the edge of the welds.

Cheers,

red

[The Nutty Professor]

I just wanted to see what would happen. I have a cheap Harbour Freight welder but it does what I need. I found to much heat is bad. You hole the metal very easy. A touch and go method worked best.

[The Nutty Professor]

Well I couldn't stand it anymore and the lights and horn and other crap had to go. I was bend over so long my back started doing the hokey pokey. Then I told myself this bending over ain't workin, so I grabbed the subframe and the top of the triple clamp and lifted...oh about a foot before I realised the bench is waist high on me and doing a "Clean & Jerk" with my Mid was out of the question. I must have sat there for 15 minutes thinking about how I was going to get "TN" on the bench. Then I had a real Dee Dee Dee. I had a motorcyclelift that had been sitting in a corner for at least a year. Some...aaahhh person gave it to me because...let's just say my wife was pissed when I brought it home and told her this women just gave it to me. No I didn't do anything for it but I think she was hoping for the future. speechless33 OK major sidetrack. I also vented the gas cap. The little brass nipple is from a brass fitting they sell in Home Depot. Its part of a ball valve system. The fitting was something I didn't need for my another project. The hose is from the emission system that "WAS" on the bike. Ripped that crap off today also. I'm still trying to figure out how I want to close off the opening's were the lights are. The rear turn signal will be easy I think but the front head light area and that rear tail-light are going to take a little thought. I've had nothing but bad experiences with fiberglass so I'll leave that part of the project until near the end. And the beat goes on...

Thanks they sell the lifts at Pepboys. Good buy. Bodybuilding trophy. Stuntn I rode it today just like you see it. No seat just the tank. Hard on the butt, but I didn't notice until I stopped riding.

Something I forgot to mention about the semi-auto motors. The are very snatchy which appears to put a hell of a strain on the chain. I still have the cheap chinese chain on and I've had to adjust it continually. At first thought the adjustor was moving but checking it it's not the chain is stretching...ALOT!

lol you guys...
the bike was naked!
its naked right now cuz i just finished welding all my nuts to the frame for ease of disassebly
im very happy with that and i only used 7 rods or so lol
i also flipped my rear sets just to see, and it feels pretty good, i have to ride it tomorrow
im only 5'9 so it doesnt bother me to have my leg up higher and im not into knee draggin yet
now i just need to go fully hard core and cut my kickstand off, then i can lean till the tires slip, pretty far

[The Nutty Professor]

Now that I've stop the laughing jag I can update the thread. I spent all day on"TN". Most of if was getting thbodywork to fit like it should. Being a race bike that seems like a major waste of time. Not to me. Ever part has to fit as it should maybe I have OCD I don't know? I posted a few photo's with this newest post. I remember a lot f you guys talking about the crappy palstic on the X18. Maybe part of that is the stress put on the bodywork by the mounting screws. I found a few bodywork screws from Honda CBR's. The screws hold the plastic without putting stress on the mounting hole. I had to open the hole a little and I had to use a tap so the screw would fit but in the end it worked great. I had to re-tap most of the brackets. The biggest problem was finding bolts. I thought I had a good assortment but this little project put the smack down on that. Ebay here I come for a large supply of aircraft grade fasteners. A major advantage of the screws is that they are hex top bolts which allows me to use a t-handle to tighten them down. I'll keep it comin' like it or not. The one thing that keeps beating me is the exhaust. I don't have enough machining equipment to make some thing from scratch so I've tried to re-use someof the original parts and that's making it a nightmare. To Be Continued...

[swheels]

Ah yes some nice work going on..Man i can't wait till shes done.But take your time just as long as she's ready for next years race season.thumbsup2

[The Nutty Professor]

Not that I plan on doing this anytime soon, but how about a few ideas for the base color of "TN"? I need a simple color because repairing metal-flaked paint on a race bike is not an option. The one color I won't use if flat-black! I really don't like it although I know a lot of people do. I'm going with a Native American theme as the decal overlay. So it will be the base color and strategically placed decals just like a race bike. Base color makes for easy repair and the exterior design of stickers makes finishing up fast. Let the fun begin rock2

[rednek01]

well with the indian theme what about a earth tone? like a tan or something dunno

If you're going with a Native American theme I have a couple of colors I think might work for you.
Sand or Beige........like the camouflage used on our military Hummvee's
Turqoise blue....dare to be a little different, but white and turqoise would be a nice combo and the colors were used by our Natives.
My wife is an Archaeologist and I help her sometimes with surveying, mapping, and locating sites.......I've seen pottery and burials, and beaded jewlery on the remains of the dead. The way it was, definately isn't the way we know it as Hollywood has made it.
It's amazing how over a couple of thousand years ago our Native Americans or should I say Native Indians were able to produce such vivid colors, elaborate tools, pottery, and clothing with such limited resources.
Anyway, enough of the history lesson.
History class is over friends.
You're gonna have some nice ideas with this one Nutty!
Good Luckhangloose

[The Nutty Professor]

Boy trying to put this exhaust together the right way is a long process. I keep making mistakes but I'm learning from each one. I have a plan that will work but it will be long and drawn out. I'm trying something else to see if it will work first. I'm also trying to figure out how to route the header but until I finish the pipe and the 125 motor routing a header will have to wait. I'm also looking for epoxy resin so I can glass in the headlight openings. Anybody know what the GM plastic body filler is called?

OK the exhaust has officially kicked my butt banghead not having a lathe is causing all my problems. I can't re-use the end caps from the stock pipe. I have the core figured out but having tight fitting end caps is a major part of an exhaust that works right. Anybody have any ideas for fabricating some? I had the idea of building because then I know what's inside and what I'm working with as far as the header system goes. Now for the kicker angry_red I was looking at Smart Shock and measuring the fit. I was pissed when I saw there's a chassis crossbar that obstructs the computer unit. I would have to mount the shock upside down to make it clear. I could cut the bar and re-enforce it higher but then there's the battery box. I could move that (I have to have it for some of my electronic equipment even when it's a total loss system) and use it as ballast on the front or under the tail? This is becoming and exercise in real race bike building and that I did not expect this so. But I love a challenge and it just means I have some tools to acquire boxing11

[The Nutty Professor]

The old man's back is killing him. I've been working 3 straight days on "TN" . Got the wiring slapped together for now. The ignition switch is gone I'm down to a kill switch and push button start. All the switches are on my new aluminum dash. Hate the way I made it but it will work for now. Gauges...gone waiting to install my tach which just got here but I haven't opened the box yet. Added swingarm spools now I need a swingarm stand. Put frame sliders on which were originally Suzuki swingarm spools. They were huge for a Mid swingarm but perfect for the frame. Added heel guards from me FZR. They're aluminum but they're large also. I drilled holes to lighten them up and after I ride them I'll probably cut them down but I want to see how much of them I will use with my feet before I start cutting. I also started replacing a lot of the bolts with hex head bolts for ease of maintennance. A bolt from the rearset was brushing the swingarm and I didn't notice until I started all the work in that area. That had to be causing some serious binding but I haven't pushed the bike to the limit yet so I haven't felt it. I can't wait to get rid of the extra wires I don't need. A few more things and the 125 starts to get built.

[Supercharged]

only trial and error will make the bike come to life nutty, also i gotta know what does " TN " stand for?

[Blitz$M.Inc.$]

we all kinda came up with it
'The Nation'

[The Nutty Professor]

Yep trial and a lot of error.

[Blitz$M.Inc.$]

awsome pics bro
its like when i saw Swheels bike
i said oh crap hes for real
please paint them sliders
so now that you have it, does it meet your expetations?
would you have liked to try a different model?

[The Nutty Professor]

Yeah it meets my expectations. Blitz the sliders are totally for function not looks. I plan to change the paint on the bodywork anyway and they should blend in to your liking moon1 Besides that's delrin and it doesn't hold paint for crap.

[swheels]

She's is lookin gooood Np.It's gonna be great to have another different style bike out on the track to mix it up with. Although these bikes share mostly the same parts but they still have there unique characteristics that may help on certain tracks or hurt.But we still drive towards that common goal.The top step on the podium.To get there is no easy task and to stay there is gonna be even harder.thumbsup2 Just admiring your work as well as.I love to see and hear what people are doing to improve any part of their bikes.It shows commitment.thumbsup2

[The Nutty Professor]

I have commitment or maybe I need to be committed bluelaugh

[The Nutty Professor]

Check out the comparison to the stock parts. The quality is off the scale. The tach isn't hooked up yet but I want the new harness and dash before I do that.

[jsosh93]

Question man.. Why would you get an x22? There pretty ugly plus they are semi auto! So do you plan on an engine swap? if so how r u going to put a foot brake on and stuff? lol just seems kinda crazy. well i guese ur gona keep that stock 110

[The Nutty Professor]

1. I think the X18 is fugly just my twocents. The X19 ain't much better. I can always change the bodywork to the X7 which has about the best look.

2. The chassis and swingarm are better on this bike. I've compared a X19 to mine and the way it's made and braced isn't even a close contest the X22 wins.

3. I already have a 125cc 3 valve head motor waiting in the wings.

4. The rear brake setup allows me to put a thumb brake system on without a lot of plumbing work.

5. The bodywork that is on it is better made than what I saw on the X19. The plastic was thicker.

[jsosh93]

LOL man dont get so defensive. I agree te stock x18's do look ugly. The x22 looks ugly stock also. I think all these body panels require a paint job to look nice. Were on the smae side man lol we both love mid bikes. So you plan on having a clutch and a rear brake both on the handle bar? Thats pretty cool man oyu have a great mind for this stuff.

rock2 thumbsup2

[jsosh93]

Hey Nutty Professor Did you used to be Hglenn on Pocketbikeplanet??? by any chance lol?

[The Nutty Professor]

Dat be me bro cowboy I'm not being defensive just putting it down moon1 I plan on painting her.

[jsosh93]

AHHA i knew it man do u remember me? Jsosh93? Lol i remember u always talked about geting an x22! HAHA cool. Ya i plan on painting my x18s plastics probobley Flat black, everyones doing it and it looks pretty cool. LOL well havnt talked to you in awhile i didnt know where you've been. I have been at jasons forum minimotoplanet just recently found this one!

[The Nutty Professor]

Yep I got ya now. Welcome to the best damn site on the web cowboy

[jsosh93]

haha ya im already liking it lol. you should join over at minimotoplanet.net its another great site and we can use knowelegable people over there like you!

thumbsup2

[The Nutty Professor]

Maybe but I've got my hands full here

[x19soysauce]

hey man dont br disen on my bike i love the x19 its bigger then all the other bikes it doesnt look bad to me i think all the others are ugley to exept for the x7

[The Nutty Professor]

Well I now see where all the hatin' comes from about e-start bikes. THEY SUCK! I never had electrical starting problems with any of my 1:1 bikes. If I did have problem it was fuel delivery. Well I went through the whole routine when my bike wouldn't start. It's getting plenty of fuel, no air leaks, and I removed the cap to make sure it wasn't a vac-lock. I was running out of time and actually freezing my bullocks off when I called it a day. I didn't get a chance to check for spark that's the first thing on the list tomorrow. This just pushes up my time table on starting the 125cc build-up. Anybody have a suggestion on what carb they prefer? That is a major part of what I'll need. The carb on the bike now is totally out of the question. I'm not looking for size answer's just maybe make, model that sort of thing. If I can find a decent downdraft unit that will solve the problem but so far "No Joy". Oh the Brembo calipers. These babies are jewels but I found out that there is no-way to use stock 160mm rotors with them, well there is a way but it takes a lot of machining of the stock fork leg and making some intricate brackets again involving machining which I don't have the talent or the tools to do. The smallest size rotor they will accept is a 203mm Akunar told me that but I'm a show me kind of guy. I did a lot of measuring and mockup with cardboard of all things and that seems to be the way to go. I've got plenty of aluminum stock to cut out brackets but I need a bandsaw to cut them accurately. I see that on the top of the X-mas gift list for me. I'm looking at some Hope-Tech rotors I like the aluminum carriers and the buttons which allow the friction surface to float but we'll see.

[swanni06]

I say go with a mikuni 24mm or 26mm carb Nutty...stock carb is 19mm on the 110cc witch is still too small it needs atleast a 20 or a 22mm carb on it.

[Blitz$M.Inc.$]

my 26mm taper bore mikuni has been great for me
i can kick my bike one time with no choke and it will start
prior to getting that, i had nothing but carb issues

[swheels]

Oh those bremi's are sweet.Can't wait to get minds.I konw i was working on a bracket for these.But if you can,could you hold the caliper up to the the disc and take a pic.Then i could get a better understanding of what could be done.I do have away i'm just not sure if it will be good enough to work.

[The Nutty Professor]

Your wish is my command "S". I'll do it first thing tomorrow. I think I'll take as many photo's as I can. Some on the bike and some with the wheel off and some with the disc so you can see the problem.

[swheels]

Cool cuase how i have it pictured in my mine it should work.And i'm pretty sure you've thought of it already.But just to give you an idea of what i'm talking about.i would start out with a with a flat piece of metal or alu.Drill the 2 holes so they mount up to the stock caliber position. The where the radial caliper is gonna bolt to you will have to fold the meat over.So that the caliper can be bolted to the plate.(of course you'd have to cut out the plate so that the caliper has room to fit.So you'll end up with 2 tabs that will hold the radial caliper on.

[The Nutty Professor]

Sorry a couple of these are blurry. I was trying to get the best I could and put them up quickly before I have to go to work. The ones that are blurry aren't that important but if you want them clearer just let me know and I'll retake them and repost. I used photobucket because I wanted higher quality if you needed to upload them to use. Here ya go:

http://i189.photobucket.com/albums/z216/NuttyProfessorPS/DSCF0080.jpg

[swheels]

Ok here's the design i was thinking about.If you can make the markings then i should be able to mill out the bracket for ya.

[The Nutty Professor]

After taking the photo's I thought of the same design but I can't mill it. I might be able to cut out the general shape but if it takes more than that I'm screwed.

I started taking apart my 3 valve today and was (Big word) aghast at the amount of slag in the casting. I grabbed a small pick and pushed on some of the "Suspect edges" and they began to flack away speechless33 They had nothing to do with the structure I'm just not use to work-man-ship that is this rough. I still think 125cc sold me a real diamond in the rough. I looked over the head for about 2 hours and I can see major advantages once it's "worked".

[Bri6672]

Hey nut if you need a carb let me know I have one of those mikuni tapper bores sitting around that I dont use. Here is the bracket I made to mount my caliper.

Note that I had to cut the front fork a bit to make it fit. The caliper is huge and barely fit but man this thing stops on a dime!! I did a Nissin resevior and ASV brake lever to go with it. I am sure the Brembos would compare pretty well.

[The Nutty Professor]

Bri that's looks like the rear caliper on my X22. I can get the Brembo's to fit it's just when I can get it done.

Here are some photo's of the 3 valve. I noticed that the cam appears to be standard. The rocker arm is the specialised part. It branches off into a Y from the cam. Both valves use the same cam lobe.

For the bracket you can also use a flat piece of steel.where the radial caliper will bolt up to.Weld some nuts to the spot the screws will fit into for the caliper.
If you make a cardboard mock up then trace it to the piece of alu i can mill it out for you.I have a milling machine.

[The Nutty Professor]

When it comes time I'll take you up on the milling machine "S". So from the blurry picture of the cam it looks just like any other cam huh? I'll take a photo of the rocker and you guys can see how they did it. Kind of ingenius if you ask me. The only thing they changed was the valve size and angle in the head but utilized most of the same parts so they kept the ability to throw any cam in there from previous engine designs.

[Blitz$M.Inc.$]

that one lobe looks pretty wide to me
i bet thats it

[The Nutty Professor]

Blitz I don't think the lobe really matters. The foot of the rockers is larger but as long as it on the lobe will there be a bad effect? Now that I think about it I wonder if the feet float a little? Meaning from left to right. If they do that would account for the need of more room or a wider lobe. Red, Schofell, Or Swheels any thoughts on that?

[Blitz$M.Inc.$]

heres two i had, neither are compatable with yours

[The Nutty Professor]

I see what you mean. I think I'll take some measurements of it and put them up and see what rolls out. Man I bought a micrometer thinking I would use it once in a bluemoon, now I wonder what took me so damn long to get one. I measure everything now and using those measurements to build things makes the parts a-whole-hell of a lot nice and better than I use to put out. All that for $15 at Harbour Freight bows_smilie

[The Nutty Professor]

Swheels here's the bracket I was talking about. They are sold in different sizes and don't cost that much at least on Ebay.

Need photo's before I can judge, Nutty. You would want the cam lobe centred over the contact area of the rocker to avoid binding or wearing a ridge on the rocker or cam lobe.

[The Nutty Professor]

That's what I thought. I'll get you some better photo's and you can see what the deal is.

[The Nutty Professor]

I thought I had the electrics figured then I started having "starting" problems. For the life of me I couldn't figure it out. Then on the way to la-la land it hit me. I was leaving the kill switch in the on position thinking it really didn't matter. Well after removing the ignition switch and routing different wiring the CDI was getting a steady diet of electromatricity bluelaugh I think this was causing a slight over heating problem and making the bike hard to start. Well I made sure the switch was off and let her sit all day. Went out to start her and after a few bumps on the starter she fired up again. Problem solved, but I still hate e-start. It's nice on the modern 1:1 sportbikes but on ours what do we really need it for dunno The story continues popcorn_smilie

Now that my weekend has started and I have a little time I going to see if I can get to those photo's Red. Hey did you heard about Casey's shoulder injury in his crash. Sounds a little worse than they're letting on. I mean he's going to miss the Ducati bash for the championship win speechless33

[redryderaus]

Latest news is he's going to get treatment for it here in Aus over the Xmas break.

Good deal. Hows your project coming along. I know you'd rather have a newer model...but hey that will come with time. Also the pressure you used to try and get a Mid is it working?

Standard 'E22' cam in those heads. I just don't remember if it's a 'long' or 'short' unit. Crower's import G2 grind has been confirmed to work without clearance issues in those motors using the stock piston. Mark at AHP minis has been flycutting his 52.4mm high comp pistons to provide appropriate valve reliefs for the 3v head.

DrATV sells units with a bit more lift, as well as providing measurements so you can tell which you need.

http://us.st11.yimg.com/us.st.yimg.com/I/dratv_1978_135533128

That shows how to tell if you have a long or short cam.

http://www.x386.net/TTR/tech/cam2.html has the specs, look at the 'E22' style units.

[The Nutty Professor]

Kurlon your info is right on time thanks bud. I'm just starting my 125cc build up. Again thanks man. If you got more let it fly. rock2

[Kurlon]

I currently have all of my various tech info tucked away at http://www.x386.net/TTR/tech and am now going through the process of 'wikifying' it. The work in progress is at http://207.5.176.26:8000/

[The Nutty Professor]

Today I start porting and polishing the 3 valve head. Photo's to follow. Do be impatient this process might take a few days or a few weeks. I work slow because I can't put the metal back once I take it out. Yes I can add epoxy but I'd rather not. Here goes nothing speechless33

[The Nutty Professor]

banghead Screeching halt! When you start a project make sure you have all the supplies you need before you start. I thought I had, and that's where I made my mistake. Thinking always gets me in trouble. I was smokin' along on the port job when I got to the point on one intake runner where I needed to straighten out a hump. It was obvious just by looking at it that it would give the airflow fits. I visualized the hump as a ramp. When the air went over it it would push it up slam it against the wall above it causing it to tumble. The air already at the top would hit that...chaos speechless33. Well I needed sanding drums for this little adventure...1, 2, ...where are the other ahh crap! Those where large drums I bought not the smaller ones. Tried searching through the Dremel kit looking for something else to use. No dice! Lowes here I come. After looking and doing just the little work I have I can see there is a lot to be had working one of these heads. Now I see where Takegawa has the lead it does. It's not the parts it the refinement they've done. I can bet if you took a chinese engine and blueprinted it then shave, smooth, and balance it and it would do wonders. twocents A second revelation. I picked up the cast jug from my 110cc 3 valve head then the aluminum jug from the 125cc stroker I'm going to add. The weight difference was out of this world! To Be Continued

[Blitz$M.Inc.$]

i didnt have the right tools when i did my head either
so i just cleaned up the slag and buffed it up some
later on i got the right stuff, and did a bit, im scared to push it tho so i stopped

[The Nutty Professor]

Well you could say I've done this at least 4 times already. On a 1:1 bike head it's 4 of what we do moon1 for 1. I studied every cylinder head I could get my hands on or a accurate drawing of.The one thing the well designed heads have is they all have a "STRAIGHT SHOT". Give the intake or exhaust charge as straight a shot as you can without opening the walls to much. Sometimes this has to be accomplished with closing the walls down. But considering the walls looked tight to me and measuring the opening to the intake the tract was barely wider than than the largest carb available? The intake opening started at one diameter then 1-2mm in there was a step up closing it down and as it branched into the 2 tracts they tightened up again. I had no way to measure it deep inside so I had to eyeball it. I stuck the largest bendable object I could (That was soft) and visually compared the space and it wasn't even close to being the same on either side and like I said it had closed up. First the intake, then the exhaust, and finally the intake exhaust face of the head. After that dunno maybe cam, valves, and springs.

X-mas sale at Harbour Freight so I bought the rotary bits I needed there. 205 pieces for $14. More sanding drums than I need for this job but hey I expect there will be more. Today I finished the rough cut of the intake and exhaust runners. Now all I have left to do is smooth down the intake a little and polish up the exhaust and she's ready. Sounds easy but the polishing part takes the longest to get right.

[schofell84]

the polishing part is a pain in the ass. i havent tried wet sanding yet. maybe you can give er a spin for me?

[The Nutty Professor]

the polishing part is a pain in the ass. i havent tried wet sanding yet. maybe you can give er a spin for me?

Tried it today and the stones I have are to big so I have to go to fine sandpaper or the brushes I talked about before. The work wonders but you wear them down quick.

[schofell84]

yeah i like those pad deals, i bought a few. hrmm, maybe im just a lazy pile and i need to try harder :P

[The Nutty Professor]

yeah i like those pad deals, i bought a few. hrmm, maybe im just a lazy pile and i need to try harder :P

I put a TV, VHS, and a DVD player in the garage. I would go crazy if there was something else going on but the whir of the dremel. Yeah when I into it I miss about 99% of what's going on but when I stop and start measuring I need other noise around. Job made me like that. 8 1/2 hours with 2 radio's going off I'm not use to having it quiet.

[The Nutty Professor]

Went to install the K2 Smart Shock and found out it's not a direct bolt on. Oh well nothing on these is easy so what makes me think this would have been. Now the back of the bike is apart and I think while I'm at it I'll re-do the swingarm. Give it a little better look and maybe add some bracing dunno As for the shock I have to fabricate a bracket so I'm sitting here staring into space trying to put it together in my head before I even attempt to draw something out then put her together in metal. I also pulled the rear brake caliper off and WHAT A BRICK. The damn thing weights a ton. I think I'll use the front brake on the rear once I have the Brembo's online.

[Supercharged]

reinforcing your swingarm would be a time consuming but worth it you cant afford to have it twist, for the mid's the x22 seems to have a stronger frame out of the box so maybe it wont be that much trouble...

[The Nutty Professor]

I have a sample adapter put together for the shock. If it works I'll see about having it milled out to a nice aluminum piece. Right now the piece is steel. I working on the brake adapter too. All I have now is a sketch without measurements but I'll see how it works freehand dunno

Thanks Bro. One less thing on my list to worry about.

[The Nutty Professor]

What did I put in the bead blaster? The swingarm was the biggest piece and it wasn't that big a deal. When I started I was going to blast the paint to rough it up to apply the paint I had in mind. Well image my surprise when I hit it with the blaster and the paint seemed to melt off speechless33 I also hit the triples because I hate that cheap shine they have, and primarily because I don't really trust the metal but it's what I'm going to use for now. I am applying a black paint to the parts for practical reason's not for looks. This practice started a long time ago with racers. By painting the items you can see a crack forming. The paint should split and you can see the shine of the crack easier through the paint. I also took the paint off the rearset hangers and that paint came off even easier if that sounds possible. The next piece I plan to blast is the entire frame. After I take the paint off I plan on welding gussets onto 3 areas of the frame. I think I might put them at the bottom of the frame, two near a point on the swingarm pivot that looks suspect, and maybe the steering neck. Then I plan on cutting away the metal they welded on to screw on the kickstand and some of the metal for the battery box. I might cut it out completely and replace it with a fiberglass or aluminum box. I'll still need if for now to run a few elecronic parts. I've also got a question for you guys...has anyone used one of these on a bike. I know a few people who've used them in cars and liked them but I don't know how well something like this would work on a bike?

I would post pictures of the blasted parts but what's the use it's just raw steel and aluminum. When I get a good coat of paint on them I'll post that.

[swheels]

Iv'e never used one but that is excellent.A great way to get track data to let you know if your heading in the right direction.Down fall is someone like me will become a slave to it and never stop tinkering.thinking_smilie

thats wild there
id be happy with a reliable tach

[The Nutty Professor]

I bought the Akunar tach. I'll put something up on it as soon as I get he bike up and running and the tach back on. thumbsup2

Akunar is selling a Tach? Got any pics? : )

[The Nutty Professor]

Yes it's a simple digital tach. I put the lead weight no stoppie caliper in there so people can compare something they know to get the approximate size of the tach.



http://i189.photobucket.com/albums/z216/NuttyProfessorPS/DSCF0066.jpg

I not saying it's the best or even the worse. I was ordering from them anyway and needed a tach. The unit is small and simple. No more bouncing needles angry_red

[The Nutty Professor]

Hey anybody seen one of these in action. They look very easy to install and would take care of a few clutch problems I've read about and the price is very nice thumbsup2 $49.95 plus shipping thumbsup2 And I wonder if I could adapt one of the Akunar radial brake levers like I've already bought to function as a clutch assembly? If I can then I only need the throw-out piston assemble on the end of the cablethinking_smilie

[mishka]

ya those hyd. clutch levers are awesome, so ive heard. im getting myself some soon... idk about the different lever, but i need to make mine a little shorter cuz of this...

its the 4th and 5th picture on there, but i wanted to make it look alot cleaner.

what do you guys this? is that what u where looking for too nutty?

[The Nutty Professor]

Didn't have any idea what I could work on today so I decided to see if I could put together a mock-up of the brake mount I had on the drawing broad. I started the mount trying to use the back brake disc because it was larger and seemed like it would be easier to make a mount for. Well once the mount was done and I tried to use it on the disc it just won't work? I tried to shave a little here and a little there, but no dice. It just didn't want to work. So I removed the larger disc and put on the original disc and I'll be damn it everything fit no problem. I still have to shave somemore off the bracker because of the disc is smaller but that should be a straight forward modification. I've put a few photo's on here with it mounted. Tomorrow after I do the last Modification I'll throw up some photo's of just the bracket.

http://i189.photobucket.com/albums/z216/NuttyProfessorPS/DSCF00704.jpg

I made the bracket out of a press-board because it's easy to work with and if I screw up I just throw it in the fireplace and start over LOLOL Maybe after it's made with aluminum I can take some of the metal out to lighten it up. But considering I want to use aluminum it might be light enough without worrying about it?

http://i189.photobucket.com/albums/z216/NuttyProfessorPS/DSCF00701-1.jpg

After I can it done I'll have to find someone who can mill it out for me in aluminum because 1. I don't have the tools. 2. If I did I don't have the skill.

http://i189.photobucket.com/albums/z216/NuttyProfessorPS/DSCF00703.jpg

Now what do you guys think? Anybody see where I can improve this simple design?

[Blitz$M.Inc.$]

wow that looks great, i like it
me me me me me me
is the rotor directional (and backwards) lol

[x19soysauce]

cool how much were those brakes man it looks great great great bro

[The Nutty Professor]

Yeah Blitz they are. I've got a second one waiting in the wings stirthepot

[Blitz$M.Inc.$]

i cant imagine youd need another one of those calipers, for what to do stoppies lol
i dont complain about mine much cause i know they wont lock up and throw me like a x6 did one time, but then again i dont stop too fast either, still, i want one :)

[Pinto93]

I'd love to have some of those. How long did it take for you to get that bracket correct?

[The Nutty Professor]

A couple of days. I sketched it up a couple times. Measured and re-measured. Then I sat down and tried to think through braking force on the bracket ect. I at least wanted to try and get it right without over thinking it. Put the metal where it needed to be that sort of thing. Then yesterday I sat down a put it together the mockup which took about 3 hours and most of that was because it won't fit and I wasn't about to rush throught it. Oh and I had to stop and go flip the burger's outside on the grill. That part sucked it's down to 35 degrees here now. Any of you guys live or lived somewhere with high humidity year round. Well it sucks. When it gets cold it get f-censor_d cold. The humidity is so high is won't snow. If it rains you automatically know it's ice and sleet. The cold soaks through your clothes like your standing in a freezing swimming pool and it takes hours to warm back up. Don't say layer your clothes...That does work but for only so long. If you get cold that's it game over. Sorry I went off thread but can you tell the cold SUCKS here?

[swheels]

They look great!! NPthumbsup2
I thinking that when i got my set in.That i'd make the bracket up for ya.But they would have been way off because my triple trees are wider.But my offer still stands.thumbsup2

[The Nutty Professor]

With this bracket even if the width of the trees is wider a thicker piece of stock can be used or a spacer plate using the same bracket can be used. At most as far as width we're talking at most what 10mm? I know that's a lot but a spacer might/should work? The spacer would be on the fork leg portion. Or the small area I cut out as a relief would be shallower or not cut out a all. When I post the other pictures Swheels you'll see what I mean. It will work for you you'll just have to re-measure a few areas.

[Kurlon]

What did you source that caliper off of? I've never seen smaller radial mount Brembos like that before... my NSR50 front end could make use of one of those... :P

[The Nutty Professor]

OK now that I can get up off the floor? King Akunar sells them new.

http://www.akunar.com/BRAKES_ak.htm

I know good shizzle when I see it so I bought two. Should have bought more bluelaugh

[Kurlon]

Ah, last time I was at their site, it was all motor parts... wonder if I can get a full catalog out of them...

Bracket looks good BTW. If you have good measurements, you can draw up the design in emachineshop.com's app and have them do the work. It's pricey for a one off, but doing them in quantity makes the price per unit fall quickly... assuming you want to share your toy. : )

[The Nutty Professor]

I didn't think about a full catalog. I wish I had one. As for sharing the toy not a prob at all. I can't see it fitting to many application as it is. I want to have one fabricated then see what happens. Believe me if I could produce what you see so can anyone else bluelaugh

[The Nutty Professor]

Here's the bracket off the bike. I still havaae yet to put accurate measurements on it yet. After the last modification I can see that I have to redo it. The bracket fits but it's off by about 2-3mm's. Here you go and again I would like feed-back. If it's bad I really want to hear it. I'm putting my butt behind these and I want it right.

[rene13]

I think it looks good. Are you going to have it milled out of aluminum. Are you going to lighten it? It look not to different from this.thumbsup2

[swheels]

Trust me Np they will work fine.thumbsup2 It's gonna be alittle while before mines come in.Now that the christmas rush is on.

[The Nutty Professor]

The second time mocking this up went a lot faster. There are a few very minor flaws but that's because of the nature of the material I was using. Wood products splinter and flake along the grain or layup pattern (OSB). Any way I was able to move the caliper closer and that put more pad on the disc. I hope this thread isn't boring the crap out of you guys? But I'm having fun doing it so...live with it bluelaugh

http://i189.photobucket.com/albums/z216/NuttyProfessorPS/DSCF006mlk91.jpg

The one thing I want to do is play around with one caliper to see if I even need 2. Two radial brakes my be way over the top. But I know how I like my bike to stop and I'll find out real quick if one is enough. Another thing is I'm worried that one caliper with have to do to much work and cook the disc. Two disc mean that they don't have to work as hard. We'll see how it goes?

I've bead blasted the frame and sprayed rust converter on spots all over the frame. Now that I blasted her I can see there was actually rust under the paint in some spots and rust up behind brackets in others. I also sprayed the area where I cut off the kick stand tab but I grinded down the edges first. Now without that tab putting the lower on should be a lot easier. Tomorrow I prime the frame and paint the swingarm. After that I think the bearing races in the neck are going to get a polish with the dremel. That should be enough for one day.

[swheels]

I cant' see why you couldn't get a bigger disc on there now.dunno

[The Nutty Professor]

Oh I can. I was just trying run to with what we had because of the problem we had trying to find a bigger one.The old bracket would fit a larger disc. The new one fit the smaller one. cowboy

[rene13]

From seeing the dualies Swheels has on his and the stopping power, you probably won't need another. His has two pistons and is enough to flip the bike, just imagine with two four piston calipers.bows_smilie

[The Nutty Professor]

Oh I know but all options are on the table. If duals gives me easy one finger braking and alot of feel. I'm going with it. One disc will probably do that considering they're radial.

[rene13]

I'm installing duals on my bike, but I am using the two piston Brembos.

[Kurlon]

I've got a two piston caliper gripping a 220mm rotor on my NSR50 front end, and the rotor is getting hot enough to discolor when geared for 90mph and racing. I'd love a twin rotor setup just to spread the load.

That is exactly what I meant. A blue disc is a bad thing.

Finished painting the swingarm and other small parts. Because of rain and other X-Mas time things I couldn't/didn't get to the frame today, maybe tomorrow.

[The Nutty Professor]

Tired as all get-out. Worked a double but I came home and started on the frame and finishing the swingarm. I put the spools back on and checked for missed spots. I found a couple and touched them up. I primed the frame and started painting it almost as soon as the primer dried. I also painted a few other parts while I was waiting for the frame to dry so I could move her and paint other parts. If you find a lot of mis-spelled words on this post that't because I'm literally falling asleep at the keyboard. Need serious shut-eye. To be continued.................

[The Nutty Professor]

Well the swingarm is done! Nothing big just blasted the lead based paint off and added a tough finish that will hold up on the track.


http://i189.photobucket.com/albums/z216/NuttyProfessorPS/SwingArmRe-done2.jpg

I took the inner fender off to do the paint and I will probably leave it off. It has a function, but it's made out of some really cheap material and may be more hazardous than it's worth. But I put it on for a photo-op.

http://i189.photobucket.com/albums/z216/NuttyProfessorPS/SwingArmRe-done4.jpg

More than likely I'll cut it down and use a shorter version. If I screw it is up so what I didn't really want it anyway. Oh before you ask (If you noticed) that is not a funky color fiberglass cloth. That's Kevlar cloth that I have a stash of. Beautiful ain't it! I plan to re-enforce the inside of the body panels with it. Down side is it can be a little heavy and a B-Ach to cut, but I'm only putting it on the high spots which are the most likely to take a real beating in a low-side crash. The frame is next....

[schofell84]

you didnt box the swinger!!!speechless33

[Blitz$M.Inc.$]

if you lowside.....
gr8 look on that swing

[The Nutty Professor]

you didnt box the swinger!!!speechless33

Dude if you had to pick up the swingarm on this bike you'd get a hernia! I thought I might have to close her in until I got the bike and looked at it. I may be wrong but I can't see me putting enough force on it to get it to flex. The frame will flex long before the swingarm does. The swingarm might crack because of poor casting but if it does closing it in won't help twocents But who knows wouldn't be the first time I was wrong. And yes I know being wrong this time could hurt. Not being stupid just calculating risk.

[The Nutty Professor]

Finished the frame and slapped the swingarm on to take a quick picture. The K2 is only attached at the bottom I still need to figure out how I'm going to mount her on the top. I've already made and chunked two brackets but I'll get it right.

nice job NUT
man that is a bad azz shock
i really want to do my frame but i want to chrome dip mine
i wonder how much that would cost? nothing says bling like chrome, plus its easy to clean up

[Kurlon]

Wow, that frame is tab-tastic! :P

There's more weld ons than some rat bikes I've seen... Nutty, time to get the cut off wheel out. :)

[X7rocks]

ben reading this thread for a while
and i love how guick your progress is nut
great bike cant wait to see it all together

Dude! Dude! Dude! You and Red have to really stop reading minds bluelaugh While I was finishing the frame today I scratched my arm a dozen times on all the crap tabs with crap welds and the angle grinder was singing a siren song on the work bench (The Harpy). There are a half dozen tabs on the chopping block but I want to get things together to make sure I don't need a tab to handle another function.

[The Nutty Professor]

Wow, that frame is tab-tastic! :P

There's more weld ons than some rat bikes I've seen... Nutty, time to get the cut off wheel out. :)

Well King I cut off a few tabs but she's still got to many. I'm kicking myself because I should have cut and grinded the welds before I sprayed her, but the good thing about this paint is touch up's blend in real well. I can already see that once TN's built I'll be tearing her done to do the finish work. Then reassembling her again. I got the K2 shock mounted and it took 2 days and I still have to re-fabricate a few pieces but she on. I finished late and was to tired to take photo's but I will and post them up. If the shock position works I'll cut off the stock tabs which are crooked anyway and replace it with a billet unit. The more I look at these frames the more I wish I could buy all the frame pieces and either weld her up myself or have someone do it.

[swheels]

Hey Np did you set the shock up so you can reach the controls easily?Just checking.

[The Nutty Professor]

Yeah so far with the way it sits it looks that way, but once I star putting other pieces o dunno I also found another electronic shock but it looks big in the photo's and it takes a 12v system to work. I think I look to much for high tech sometimes, but I was reading a Tard article and they're peeved that MTB rear suspension is 10 times more advanced than their systems and they seem to be locked in the 1970's. I'm trying to smoke past that wall if I can help it http://i189.photobucket.com/albums/z216/NuttyProfessorPS/Smileys/Burnout.gif

[The Nutty Professor]

This was a lot of cut, file, drill, and tap but it was fun. The little white block at the front of the bracket is Delrin. I want to change it to aluminum but that may not be necessary?

Here's the access you where asking about Swheels but after the footpeg bracket is re-attached I'll have to see about clearance.

[Blitz$M.Inc.$]

im not riding mine till next year!
so when is the next test ride, gotta do that ya know

[The Nutty Professor]

Working on the pipe again. After putting it down for a while and working on something else new ideas came up and I think the way I want to do it anyone can do it with a few of the right tools and skill is not all that necessary just patience. I haven't been taking any photo's but I'll go back and do that showing how I did it from start to finish. I'm trying to do it without welding anything. Mostly because welding is not my strong point and not many people have welding units. I should be done in the next couple days...work permitting.

[The Nutty Professor]

And again the pipe kicks my A@#$$## angry_red So I've been working on my second nightmare...(Dramatic music here) fiberglass. I'll post a few photo's soon but please keep the laughing to a low roar LOLOLOL. I no I should have used epoxy resin but I couldn't find it in my small whistle stop town. None of the auto store carried it. They all had the clear poly stuff so I tried some other stuff in sold in Wally Mart and it seems to be OK dunno I put a thin layer on the facing and a thick layer on the back. In the pictures it's still thick but a Wiz-Wheel is going to take that down some before I'm done. I had to keep reminding myself that this is race plastic not a show bike. I was spending a lot of time trying to get the contours just right. One lowside and that's a re-work. What I'll worried about now is the rear spring. Read the Shocking Revelations thread and you'll see what I'm talking about. Next week the motor gets built with the help of a real genius mechanic. He looked at my port job and gave me a few things to take home and work on. One thing he said that got me going was "Remember that 2 plug head you showed me? We can do that with your head if you really want too." After I picked my jaw up off the floor. I told him we would try it with my old head when we could get to it. Man I'm drooling over that one. I know it's just nicky-neat but I always fall for a few dumb ideas. That will be a separate step-by-step thread when the time comes.

[The Nutty Professor]

Kind of fell into a "What do I do next?" stage so I just started making stuff I knew I would want/need soon. Knowing I would be adding the Brembo's and I would have a hissy-fit if they got scratched in a simple lowside I decided I needed axle crash bungs. I found a bar of Delrin so I put these together.

Before you ask I had to make a new longer axle to get this to work. After I finished this I realized that the seat bodywork was the next little project. the seatpan was crack at a crease and I had it re-enforced with duct-tape. I used 1 layer kevlar and drilled 2 holes for the mounting points. I'm in the process of sanding down the faactory paint for the primer next step of primer.

It's hard to see in the photo but there is resin covering all of the kevlar cloth. I just added more at the parts I thought where high stress areas. That will be sanded back down. After adding the kevlar the panels are as hard as a rock. If it cracks in anything other than a crash at speed I'll be surprised. The plastic will rash but I think it'll take a lot to break. In the parts where the lenses are still there I decided to glue them in place and use them to plug the holes instead of fiberglassing over them. I will use filler to even the seams and sand and paint over them. I might glass under them because I don't really trust the super-glue. I have a piece of upper fairing filled and bondo'ed I'll put that up next.

[Blitz$M.Inc.$]

man i like those sliders, they remind me of skateboard wheels, think i might get that
most of my panels look like yours on the inside cept i used firbeglass bondo and mesh cloth, then after all that i sprayed some rubber undercoating spray on the whole inside
this cuts down on the vibration and helps hold things together, plus it gives it a nice look
when i lowsided, the tail and lower fairing got scratched and the upper windshield area got cracked, not too bad

[swheels]

I don't think if you lowside there gonna touch the calipers.Neat idea though.thumbsup2 I know from my lowside the axle bolt got chewed a bit but as far as my calipers stick out.They haven't been touched.

[The Nutty Professor]

On a couple Tard sites they use skateboard wheels but I have the Delrin bar here so I made them. Well here's the photo's of the upper panel primed.

[x19soysauce]

cool man do u have to prime plastic befor u paint it? cause i need to paint some plastic stuff and if i do prime it do i need to sand the primer?

[The Nutty Professor]

With this plastic and paint I would say sand the hell out of it and prime then sand the primer. I then wipe it with a "Prep-All" I bought from Wally Mart.

[x19soysauce]

ok so i cant just put the paint down on the primer?

[swheels]

With this plastic and paint I would say sand the hell out of it and prime then sand the primer. I then wipe it with a "Prep-All" I bought from Wally Mart.Did you decide on a race scheme.I sent you a link to some graphics.I'm pretty sure if you look through them something will catch your eye.thumbsup2

Also are you going with automotive paint?Cause you know what gasoline will do to spray paint.That automotive paint is pricey.

[x19soysauce]

is there a auto moto spray paint?

[rene13]

is there a auto moto spray paint?

There is, but it not the same.
thumb_down

[The Nutty Professor]

Haven't decided yet Swheels. I've done some race bike jobs with a can and used a second stage clear that worked great. I don't have anymore of the clear but I'm going to go get a can. I'll put a photo up when I can (Pun intended).

[x19soysauce]

i got this cylon clear from walymart how does it work and do i need to spray it on after the paint hardress during the painting process or what

[The Nutty Professor]

I always let my paint dry a day before clearing. You don't have to do that it should tell you on the can.

[x19soysauce]

hmm but like any paint u can use clear on?

[The Nutty Professor]

I know me and I should have known that I would never change my mind when it comes to the color I think should be on a bike. I love red bikes. When I had my second F2 I couldn't sleep for days after I sold it. Well I painted the one upper half I have done Radiant Red or at least that's the color label on the can. Yeah I used spray paint. It's the Duplicolor auto spray in the small can. I'll put up some photo's tomorrow if I get a chance and I'm working the tail-section too. I also cut-up the header from my FZR and plan on using that as the header on my bike. The tubes are pre-bent so that makes it that much easier. If it doesn't work I was tossing it anyway so I'm losing nothing but time. My hold-up is I can't start tacking the pipe until I have a motor in the frame. Tomorrow I'll work on the fairings more, maybe I'll get the tail done dunno ?

[The Nutty Professor]

Well by the end of next week this should just be a memory

[The Nutty Professor]

Throwing up a few of the red photo's. I also started on the tank but got a few bites of orange peel on the primer so I'll have to go back and re-sand it and re-spray it. here you go

[mishka]

oh wow man thats an awesome red color!bluelaugh
i cant wait to see the finished product!! thumbsup2

[Blitz$M.Inc.$]

ya thats lookin good

[swheels]

Oh yeah that's lookin like some race fairings now.With the headlights filled in.

[The Nutty Professor]

It was the best of times and it was the worst of times...I started on the 125cc build today and it was a lesson in the finer art of the mixed up world of Chinese motors! The mission: Take a Loncin 110cc 3 valve motor and turn it into a 125cc. The 125cc was a stroker kit removed from a Lifan or GPX based motor (Mish I forgot what you took it out of Lil Bro straighten me out please). Well forks I thought and Mish though it would be a straight drop in...HAHAHAHAHA did I say HAHAHAHAHA? The counter weights rubbed or plain got stuck on the oil retaining walls that surround the crank banghead Well we machined the hell out of the crank and trimmed some of the interior walls to make it fit. Now I have a lightened 125cc crank and it spins up fine. That was a 2 hours trial and error job. Then the cases where put together and we where off to the races (Or so we thought). We put oil pump in and tried to put in the drive rod...it wouldn't pass the the counter-weights they where still to big...DAMN! banghead OK shaft on the lathe and turned it down. Still no go. Plan number 2 finish the build without the pump drive. When we’re done and everything fits tear her down and find a final fix for that problem. Alright let’s get the clutch assembly together and keep going. DAMN! banghead The splines on the clutch pack are different! I noticed none of this because I had no idea how the damn motor went together. As my buddy was building it we just knew it would be done in a hour...like I said the best of times. After the clutch failed to fit we decided to call it a day drop-back and re-group. Oh I forgot! When we found out the crank won’t fit the case we went after my stock cases. First we checked to see if the 125cc jug would fit...What was that word again???DAMN!! banghead The stud spacing was to small. Back to the original cases. At this point I’m totally in to this build (I am The Nutty Professor remember). With the lighter crank it should spin-up like a souped up wildcat. So I’m in this to win this. I haven't had a chance to take any pictures but once it's build I plan to strip it done photograph it and rebuild her so I have a record of the measurements of the final race motor. Before you write "Why doesn't he just buy a new motor?" I don't give up that easy and if was I'm doing works...Well I'll leave the final words for a day at the track.

uh, im no expert but the gpx 125 and honda 50 style motors are not interchangeable
i cant put my gpx head on my 110, same with the crank, piston...
you opened a big ol can of worms i think
if that ever runs right you WILL be the nutty professor

[Blitz$M.Inc.$]

i think jag got his crank from a extreme motor, which is 50 based

[mishka]

hey nutty, its a gpx crank.
that sux it not fitting right! i really wanted to see
this thing run! but u said that u got the crank in there right?

[The Nutty Professor]

Yeah it's in. We have to make a few more adjustments but that's it. Blitz it's gonna run. I don't but my buddies got some seriously mad skills bows_smiliebows_smiliebows_smiliebows_smilie

Wow, sounds like Loncin's 3v motor is based on a standard import 107 bottom end...

Had you started with a Lifan/SDG 3v 107, the only problem you'd have right now is the rod being too long for the 69mm height cylinder. They run the same clutch/oil pump setup as the Jialing 125 motors. (They were one of the first motors on the market with that style bottom end.)

I'd take this as an opportunity to step back and punt.

Option 1: Find a 54mm crank and 54mm cylinder for a Honda 50.

Dr ATV has suitable bits, including a nice selection of pistons. You'll need to cut new valve reliefs on the piston, but thats easy enough. This will essentially be a bolt in affair, allowing you to retain your stock clutch/etc, and will net you with a square 3v 124cc motor.

Option 2: Buy a new 3v 107cc motor.
http://cgi.ebay.com/ebaymotors/SDG-107CC-ENGINE-PIT-BIKE-ENGINE-MINI-BIKE-ENGINE-NEW_W0QQitemZ160201214298QQcmdZViewItem?hash=item1 60201214298

This is an SDG 3v motor, which will happily accept your 57.5mm Jialing crank as a drop in. You'll need to press the crank apart, and either shorten the stock rod by 9mm, or source a shorter unit. At that point, you just assemble and rock your stroker 3v 125cc motor.

Option 3: Buy a new 125cc bottom end.

If you spend a bit more cash, you can get an Xtreme 125cc motor that has your desired 57.5mm stroke, along with a matching 52.4mm bore cylinder. It also has a sweet close ratio transmission, ideal for a screamer. The real kicker though, Honda 50 stud spacing like you have now so you can just drop that head on. (Ok, maybe not just 'drop it on' as the studs may be slightly too short. The trick here is to get some hex stock, drill and tap to act as longer nuts, so they can reach the threads below the top of the head, while providing a nice head head for a wrench to get onto. Drill out the stud passages on top of the head deep enough for your new nuts to fit, turn the nuts down where they slide in, and you're in business.)

dang dog that sux
i didnt wanna be right
i thought the extreme crank would drop right in

Ye of little faith bluelaugh It's either going to run or lunch itself. I am of the opinion it's going to run and rather well. After we stopped and started building on a R1 motor and discussing options I found out a few surprises. I've known Ted for almost 18 years and didn't know this (He's very modest and honest to the point customers rip him off angry_red) he's built 2 championship club race bikes for someone else over the 18 years and numerous runner up's. Last year he put together 5 (For the same customer) race bikes (Different styles SuperTard, X-country etc) and the guy won or placed second in every race he could enter. The guys a website rich guy and buys what he wants when he wants. The last mod I saw Ted do was put a CBR 600rr front end on a Honda CRF 450. He had already modded the rear but I have no idea what he put on it. He says he's not a machinst but I've seen him do some amazing things with hand tools, power tools, and a lathe. It's hard to get him excited about a motor but this little project has him running around the shop happy as a clam. I'm already saving for another motor hedging my bets but that's what he asked me to do before he would do anything on the motor. I keep my promises. I think the ZX-6 is going on the auction block now. Need a second motor and some leathers. And last but not least I have a favor to ask. I have a helmet that needs a custom paint job. At $400 plus dollars for it I'm not trashing it because I want a new design. How about you guys throw up some ideas for me and I'll run with it. Remember I'm The Nutty Professor test tubes and acid spills are the order of the day. I'll post a side, front, and rear shot of my helmet for you guys to overlay a design on. I was going to copy the Red Bull helmet...but that would be a copy and well they ain't paying me so they can advertise somewhere else. Besides I drink NOS not their stuff anymore LOLOLOL Let the games begin (Oh Blitz I would like to see some of your work. PAAALLLLEEEAAASSSEEE lolol)stirthepot

Oh sorry about that got so busy typing I lost my manner's. Like "S" said Thanks for the info Kurlon. With it I making my alternate plan.

[Kurlon]

From what I'm hearing, the 600 front end on matching brand 450 dirt donk swap is nearly a bolt up... add a longer shock in back to rotate the frame forward... instant 250GP geometry! : )

I'd love to have the cash to afford to build one.

I need to find a machinist friend... I need to make shorter upper tubes for a set of inverted forks... :P

And don't get too worried about thanking me, I spew any chance I get! :D After awhile, you'll be trying to find ways to shut me up.

[The Nutty Professor]

That ain't going to be easy...depending on how much shorter. Are you going to have to get larger triples after?

[Kurlon]

That ain't going to be easy...depending on how much shorter. Are you going to have to get larger triples after?

I'm likely going to need custom triples anyways, but I'll cross that bridge once I get the forks short enough.

I like that thumbsup2 Need more though. That's the base but now for the surrounding design.

[Blitz$M.Inc.$]

Nutt, this is the front page of one of my books
and the cross is a favorite pattern
sorry to post it here but you asked
my ink pics kinda suk, i never could take a good finished pic, but that was before digi cams were everywhere

[The Nutty Professor]

Blitz I like the cross a lot too. If I can style the snake to fit in it's perfect for the back panel of the helmet. I think the two circles on the cross bar will be tach's redlined the other 2 I thinking on that. The snake stays but dunno how dunno ??? Guys keep'em comin'.

[swheels]

Wow look at all the hidden talent.Great pics guys.How about a guy in a lab coat lookin like he's speeding on a midbike with his tongue hangin out of his mouth like it's just blowing in the wind.OOoo and his lab coat is blowing in the wind also.Plus holding a beeker in one hand.Ofcourse in drawn up as a toon.

[The Nutty Professor]

OK now I'm going to have to buy another helmet to add all the good stuff. I thought I didn't want a Mid Bike on the helmet just the Nutt concept, but leave it to "S" to easily change that LOLOL Here's the helmet. And before you say anything no it's not a girls helmet. It's a Mat Mladin replica. It's one of his earlier styles. It was a order for a small head and they needed a even smaller helmet so I stole it (Price wise). I have a pea head bluelaugh so finding helmets that fit well are not easy. It's scuffed on one side from a lowside. I actually had the helmet x-rayed after (Ex-girlfriends room-mate was a radiologist. Good to know the right people) the crash and it was still sound. Not cracks visible. It wasn't a crash where I whacked my head I just slide and laid my head down then picked it up when I heard it scrapping.

[x19soysauce]

sorry to say nutty but thats ugly lol mines to fancy i think its got like gold leaf a asome snake and metal flake in it but it doesnt match my bike at all lol

[mishka]

man dude that thing is BALLIN!!!!smokin_pimp
lol u should just paint over the paint job or have the same design
but different colors.
my bro inlaw fell of his bike aswell and scratched up the helmet so he just painted it flat black and now i ride with it lol:D
so ya if u use that helmet that would be pretty sick! thumbsup2
ill post some pictures of the helmet tomorrow if u want.:)

[rene13]

This is what protects my nogin. Mine hsve the chrome visor. Not bad for what I paid for it.

[The Nutty Professor]

Well what's The Nutt been up too? banghead Is what I've been doing. Where do I start? As most of you know I've been working on a 125cc build up...well we put the parts down on the bench and started working the brain cells. The way it looks I'll end up with a Franken-Motor. The 125 crank I lightened is being put to the side and I'll be using the Loncin crank. The rod and piston and the jug will also be used after I have the jug decked 4mm. What will my displacement be when I'm done dunno right now it's turning into a "This sum be-ach is gonna run come hell or high water". So I'll be in the market probably for a 138cc at the most. I'm about lower displacement and spinning the hell out of it. As for the shock deal I now have the OEM spring and a 550lbs and a 750lbs spring. I'll have some testing to do. I have way to much work and testing to do in a little amount of time. tears2 But the beat goes on. More soon.

[mishka]

so your going to go with a 138 huh? that sux.. i would love to see that custom 125 your where building. but its always good to start fresh and with a new motor.:) what are your plans for the 138?

[The Nutty Professor]

I haven't given up on the build by any means but I need a ace in the hole if something goes wrong. thinking_smilie Right now I have no plans for the 138cc I'm still chasing the suspension.

[mishka]

oh ok cool cuz i was like what? hes giving up? no way lol but ya i need to get my forks modded and a nice rear shock too

[stuntnx7]

oh ok cool cuz i was like what? hes giving up? no way lol but ya i need to get my forks modded and a nice rear shock too




i need to mod my shocks.....somebody got a write up about it

[The Nutty Professor]

If nobody put's anything up by friday I'll be taking my shock apart and changing the spring. I'll put something together then.

[mishka]

oh cool. i might just have someone do it for me. i don't want to brake mine and then have to buy need ones lol but thats cool. tell me how they work out for you. maybe u can mod mine haha thumbsup2

[The Nutty Professor]

Maybe I should change my name to the destroyer! angry_red I have what I think is a clear vision to get things done and I get half way through something only to find out my plan was CRAP! angry_red I started taking the shock apart tonight after reading the instruction manual many many times. I loosened everything up and fiddled with it for over a hour looking for a way to pull the end off to remove the spring...No Joy? I then tried backing off some of the parts that where screwed on and again I had no luck. I got more and more pissed off as each project hit a brick wall (As much as I’ve done this I should know there are going to be days like this). The one thing I thought I could get done while I was struggling through the other projects also gave me fits. I planned to prime all the parts that still needed to be painted. Seems easy right? It was until I primed each part and tried to move the part to a place where it could dry without worrying what would happen to it. Dropped one part and it flipped and landed primer-side down. A second part started to fall and I tried to catch it...I did and now my shirt has primer all over the sleeve. I finally got the parts done and I’m letting them dry. I got the rear brake caliper mounted but not without a lot of cussing and screaming. The adapter plate refused to line up and I’ve lined it up day after day for two or three days now but wouldn't line up today...Oh hell no! After I got it lined up I felt that tide might be turning...yeah right banghead banghead

[mishka]

wow man sounds like you had a bad day.
but everything seems to look good now..
but whats with your rear fairing? it seems broken.. :confused:

[Blitz$M.Inc.$]

on my bike i cut my bottom fairings out
they still bolt up great and changing the oil is fast
i also highly recommend spray can rubber undercoating
did all mine on the inside and it helps with the vibration, noise, heat, and adds a little strenth
his seat aint broke, its the angle

[mishka]

oh ok ya i see it now..:)
i was thinking of putting mine together so it can be a one piece. ( just the bottom tho) maybe bondo it togetherthinking_smilie

[Blitz$M.Inc.$]

ok but bondo is kinda heavy, so its a trade off
maybe that plastic weld would do it, and still be light

[mishka]

ya ill just have to think about it.. cuz im going to cover the front head light like shooter so what i do on there ill do on the bottom..:)

[xxlarge420]

on some of the high stress areas of the fairings sometimes i place a thin layer of fiberglass on the backside of the fairings for a little extra strength and if u dont use too many layers it still stays light and helps with the strength some and a little with vibration, but not probably as much as undercoating does, but undercoating might be a little heavier. both sound like good decisions because every midbike ive ever owned had fairings, that left untreated, eventually cracked in several different spots. right now i have a few fiberglass patches behind my fairings just to keep them from cracking anymore. i really just want to get a full set of new X7 plastics and reinforce them and repaint them right from the start, but they have to be a full set of the 2 stroke X7 plastics because the 2 stroke and 4 stroke fairings are identical except the 2 stroke comes with the complete lower fairings as well. where the 4 stroke plastics dont come with the lower fairings. its basically just a half fairing and i think that the full fairing look is much nicer and reminiscent of an actual R1.

[Blitz$M.Inc.$]

undercoatingthumbsup2
downside, oil and gas mess it up some

[QUOTE=The Nutty Professor;9325]Maybe I should change my name to the destroyer! angry_red I have what I think is a clear vision to get things done and I get half way through something only to find out my plan was CRAP!

Oh man..I feel your pain Nutty...:)

This is exactly why I have gotten obsessed with researching the hell outta project before i do ANYTHING, no matter how "simple" (i use that term in semi-ignorance rolleye0010) it seems.

However, reading and doing are two different things. No matter how well you research it, the real deal will always throw you curves. (Or kick your ass twelve ways from sundown..armyguy)

So I consider the research part critical because you got ENOUGH problems understanding what the heck you're SUPPOSED to be doing before actually attempting it! And well...any build isn't a build until you're bleeding, sweating, crying or all three.

(P.S. This reminds me of all those times I've worked on computers, got cut on a crappy case while working with the motherboard and proceeded to bleed everywhere threatening everything..ARGGGGG!! You're more pissed off that the project is going foul than the fact that blood is getting everywhere..but then it becomes one big ball of pain sooner or later...)

--55

[Blitz$M.Inc.$]

55, i feel your pain on the pc repair
everybody i did builds for i made get an antec case
ive had mine for 6-7 yrs, everything else has gotten replaced 3-4 times since then

[The Nutty Professor]

Well today was 20 times better and talking with Swheels was the reason. Thanks my man for the pep-talk. I was having a fit with the shock and Swheels gave me one small hint to remove the spring and I'll be damn! It seems I've forgotten a hell of a lot about working on things. Swheels told me to compress the spring and the clip holding it on would drop down and slide off. I had this problem with a strut on my Datsun 260Z so I've been there and done it but I didn't put two and two together. I didn't have a spring compressor that small so I had to put something together. I wasn't even pissed when I discovered that the two replacement springs I have are to small. Oh well I'm on the hunt again for springs. Then I walked into the garage after spending the day at the fun park riding Karts.

Never again will I go to that place on a saturday wave_finger I just wanted to run around on the track and see how fast I could go with one of those bricks and practice hitting the right line through a corner. Well the little "Deleted"-holes thought it was a bumper car track. Instead of running a line and trying to have fun they would zig-zag across the track when I caught them. Then when I would take the line away they would try and pinch me against a rail. I finally got tired of their crap and started cussing them out and that crap stopped. Then on my last run a little fat twat thought it would be funny to ram my Kart when it was stopped in the drive-thru pit. I got in his face and said a few things I probably shouldn't have ("That really hurt you little fat ducker. What the duck did you think you where doing? I...you're a little fat momma's boy you arse-wipe!!!). The kid took off running and I had had enough of the thuglets just running rampet so I told the misses it was time to go. After a hour I realized that the impact had screwed up my back again and now I'm doped up or I wouldn't be walking and working on the bike.

I really shouldn't have been using power tools but it was time to get some work done so I went to work on the thumb brake I have been planning. I've got it all together now all I need is a long enough brake line. The line for the rear that came on the bike won't work with the new application. But I'm happy with the result so far.

Sorry for using photobucket but I couldn't seem to get my photo's to upload.

[Blitz$M.Inc.$]

pretty ingenious
do you have enough leverage to brake good?

[The Nutty Professor]

As a thumb brake I looking to use it as a drag on the rear disc more than outright braking power. If I need it to stop I'm already in deep doo-doo. I use a rear brake when the bikes leaned over and I need a little brake action. Using the front will cause it to tuck but having a thumb brake only gives me so much pressure and keeps me from over doing it.

[swheels]

Great Np.thumbsup2 That should workout perfect.

[The Nutty Professor]

Piddling around working on a few things that I ve been putting off like re-doing the dash panel for the gauges. I think I'm going simple with this and putting up just the bare bones and not something wiz-bang. I think I'm going to add a Hydraulic clutch because I'm going to have to add one. The X22 being a semi-auto comes without the clutch and just a brake lever. Why not just upgrade while I'm at it? A cable system is easy to put together and I might do that at least for early testing. Anybody got any ideas for me to start on next? I have the motor at the shop so I can't work on it while I'm home it's just me and the chassis for now. The suspension is also being worked along with the brakes. Everything is sort of in that "In Progress" stage banghead Can you tell I'm bored LOLOLOLOL??? I guess getting the dash right and routing the wiring will keep me busy for a day or two.

[x19soysauce]

have u painted your helment?

if you had a rear handbrake you could have did like the stuntbikes do it and ran it on top or under the clutch....
