ok heres the swinger i got sandblasted.

[rene13]

ok heres the swinger i got sandblasted.


Here ius my twocents

[dna316]

yea i got the cut on the top of the pic done. im going to cut the bottom pipe and leave the top tube. the one that has the 3 welded nuts for the rear fender just so i can put the fender back on. one thing i was thinking about is what you mention about relocating the shock mounting bracket. tomorrow ill get to work on it.

[dna316]

hey randi heres some chart i found with the schedule info for pipes. i think im going to go for the schedule 40.?

[dna316]

ok so here is what it looked like outside today. so i figured what the heck lets get to mounting that swinger. oh and heres my son helping me to.bluelaugh

[dna316]

k so heres the swinger all grinded down, not painted cause i just want to make sure i didnt totaly screw up the welding part.

[dna316]

so once i got everything mounted it seemed all good. except my rear break line is to short now lol.

[dna316]

and heres the rest of the pics with the chain on. i cant wait to be able to paint it and the rims, wich ill do all at once. i want to see what it all looks like once i have all the plastics on and all that.

[Blitz$M.Inc.$]

thats pretty sweet
how much is the stretch? mine is about 6, it still takes corners ok

[x18]

Blitz did you make that it looks alot like the one off pbu except the shock mount http://www.pocketbikeupgrades.com/images/x18-esa.jpg

[125ccCrazy]

David, that looks awesome, very nicely done....

Are you gonna relocate the shock mount to get the rear end lowered down??

[Blitz$M.Inc.$]

x18, rkfitch made mine from the pbu one, the way they do it sux
dna, ya you want the rear lower for sure, look at my shock angle to get an idea

[dna316]

thats pretty sweet

the stretch is just under 6'' to. and yea im gonna try to adjust a bit the shock to try to lower it a bit but i think im going to have to weld a new shock mount. and man that bike looks nice, is that a new one?

[dna316]

David, that looks awesome, very nicely done....

Are you gonna relocate the shock mount to get the rear end lowered down??

thanks randi. yea i think im going to have to throw on a new mount for the shock. and i think im gonna try to fab a plastic piece for the chain to sorta ride on by the rearset cause the the chain seems to want to rub on the frame behind the rearst, even though the chains nice and tight. will see

[dna316]

hey blitz did you have to move your shocks top mount?

[125ccCrazy]

The chain is riding on the rear set because the swingarm is a such a steep angle, if you relocate the shock mount and lower the rear down that will take a lot of that angle out and move the chain away from the rear set..... If you look at the bikes I've built you'll notice the swingarms have very little angle and when weight is applied to the shock the swingarms are nearly flat (parallel) to the ground...The bikes ride and handle really well...

[Blitz$M.Inc.$]

the top mount is the same, the difference is where the lower mount is, its further back on the swingarm, giving the shock more of an angle and less height in the rear
the pic is the difference in seat height to my x15, the 18 was originally taller than the 15
that bike became the rising sun ninja

you using the stock shock Blitz$ ?? if so how is it working with the extended arm and extra leverage??

Gotta figure out a shock on Miguels cat and my son's when I get the swingers built and hung on those bikes..

[Blitz$M.Inc.$]

ya its the stock shock
it rides great with it and i can also use a aftermarket shock too
the mount on the swing is just a vertical plate with holes drilled for 3 different positions, so i could raise the rear up some more but i like it slammed, more realistic for drag racing
i had my stock 110 at half rev, dropped the clutch and it still brought the front tire up a bit, i didnt think it would

yea i noticed that, and thats the look im aiming for. i love that parallel to the ground look it just makes the bike look stretched so badazz.

i noticed the date on the picture and thought it might have been the rising sun. man so tight and great job all around on that bike bro. im looking into repositioning that mount and ill also be using my stock shock since a bruthas broke as heckbluelaugh

[Blitz$M.Inc.$]

what you need

[dna316]

what you need

thats what i was thinking. just need to get some square stock whatever that is like 3/4'' stock.

[dna316]

lol so i got a short ride in since its mad cold out lol, i just wanted to make sure the chains all good and all. and yea everything good. i see what you guys say about the turning radius, but its a nice ride still.

[r32rider]

blitz, is this the bike that used to be red and white? if so, who repainted it? it looks so profesional done. must be painted with a gun>?



thats pretty sweet

[Blitz$M.Inc.$]

r32, no thats what it looked like before i did the rising sun paint

[dna316]

r32, no thats what it looked like before i did the rising sun paint

:clap:bows_smilie:clap:thumbsup2
thats all i got to say about that.

[dna316]

K so i adjusted the bolt on the shock, decompressing the spring and it sits prety decent now. and the chain no longer sits on the frame woohoo. so ill throw up a pic when i get out of work.

[rene13]

This here will give you an idea on how to mount your shock. The more of of an gle you have it will give you a pogo stick effect.

I read this in a book and I will get it later and post the info later.

[dna316]

interestingthinking_smilie. thanks rene and whenever you get the chance to post the rest of the info so we can all take a look and i would like to read up on that. thanks again manthumbsup2

[dna316]

K guys i put together some drawings for my next swinger. help me decide wich one.thumbsup2. i think i like option 3 the bestdunno. if you guys want to edit any of them and add or subract anything please do.

[The Nutty Professor]

I'm not a structural engineer by any stretch but I can see a major flex point in your master piece. I did a couple photo shops to show a couple fixes. I like the enclosed fix myself. The flex point I see is where I put the down tube from the lower to the upper swingarm piece.

[FiveStarSky]

To: Dna316, tisk tisk, are you using autocad for your swinger drawings? i see a total lack in orthographics and where are your hidden lines?

sorry, Architectual Drafter here. I'm planning on doing a full scale drawing of the X15 frame, but i have to wait untill christmas untill i can get my new laptop and put autocad on it. my current desktop at home is to old to run it well.

As for the 18jixr, i'm thinking of doing a yellow and black paint sceme as well, but to help divide the yellow and black, i was planning on buying some silver pinstripe tape (from an auto store aprox $20 for 150' ) and running it along where the black and yellow meets,

Also, Could you put graphics on a bike then do a clear coat over it to help protect it? or would that be a bad thing?

yea im thinking of cutting up some 3/4'' tubes and connecting the upper and lower part of the swinger, like in your 1st pic. probably 2 or 3 pieces, not just the one. like you said im not a structural engineer but i do see what your saying about the flex point and thought about that a while back. just need to cut up a few small pieces of cross tubbing and weld that in.
thnx nut

lol I know. i hadnt put all the details into these drawings since im looking for feedback on a design first, then ill plug in all the proper dimensions and hidden lines and even add the rim and some of the frame so we can get a better look at what it will look like. but yea first i need to pick wich one i want to go with.
and yea for the pinstripe, I see what your saying and i would recomend going that route, its inexpensive and it will add a nice look to the stripes.

absolutely you can lay down whaterver colors scheme you want then once your good to go with that, you can lay down whatever grafx you want and come over the entire thing with a few light, even layers of clear. just buy the good stuff, dont try to skimp on that.
good luck and lets see some pics as you go.
and once i decide on what layout for the swinger ill get the drawings updated and you can let me know whats missing or anything i can improve on, since i just tought myself how to use autocad and had no formal training i could use any input. thanks

hey nutty, i guess im a bit confused by the second drawing. do you mean to like fill in the entire open side? cause the chain needs to still go through that opening

[dna316]

I was thinking something like thisthinking_smilie

[dna316]

i thought it would probably add good structural stability, since im not so concerned with wheight

[Blitz$M.Inc.$]

i vote #4 since thats what mine is

[FiveStarSky]

Dont worry about the autocad, the drawings look fine.

As far as the swinger you already have made, i think its fine, The shock will be where the swing arm takes all the pressure of the rider and the bikes weight, as well as from bumps in the road. IMO i think it would be perfectly fine, as the only weight bearing objects would be the shock and the lower bar. the weakest part will be the midpoint between the rear axle and the mid point between shock mount and where the swinger holds onto the frame.

However, i would weld a bar inbetween the two bottom bars , to help keep the swinger from twisting during turns and such.

This might help, kinda an equation:

Weakest point: the mid point of (midpoint of where the swinger bolts to the frame and the shock mount) and the (rear axle)

Look at my picture i included, it might help.

[The Nutty Professor]

Yes but leave a chain opening. I was in a hurry and just threw it together.

[rene13]

What shock will you be running? that should determine what you do next. You don't want the rear to sit up high.

gocha, thats what i thought and what nutty was saying to. thnx
ill throw in a piece at that weak point before i paint it up and call it good. and again im like 128lb wetbluelaugh

[dna316]

Yes but leave a chain opening. I was in a hurry and just threw it together.
lol gocha. thanks bro. ill take a look and see what it kinda looks like with the one piece and i might just add a second just to kinda even out the look if it looks a bit wierd. will see. but good catch. thnx again

[dna316]

well rene im just using the stock one for now, it did sit high. but then i unscrewed the nut it comes with and prety much uncompressed the spring all the way and now it sits allmost horizontal, and when i sit on the bike its perfect.
well ill snap a shot of it and you guys can see.

[dna316]

K guys its been a little bit since i been able to work on anything on the bike. but i got to it today. I cut and rewelded a piece of the exhaust to make an adapter piece to mount the new mufler on, thanks to ashar. heres a pic.

[dna316]

and here it is mounted. omg i love the way it sounds. nice deep roar.rock2

[Blitz$M.Inc.$]

looks like a big hollow point bullet

[The Nutty Professor]

Yeah the old Winchester Silvertip.

[X7rocks]

lol...... probably sounds like a v twin engine now.

[dna316]

looks like a big hollow point bullet

Yeah the old Winchester Silvertip


lmao, now that i look at it on this pic again, it actually does. lol


lol...... probably sounds like a v twin engine now

Man i love the way it sounds now. its been pretty decent out, weatherwise. so i been ridin but i really want to cruise and make noise. lol

[Ghost Rider]

I am mounting a similar muffler the same exact way you did... I just need that adapter piece and ill be able to run it.

Looks Good! Post a video!

[dna316]

damn. I dont have any steel stock, otherwise i would machine it for you man sorry. but yea it was easy as heck. only, the mufler it self has a slighly different id where it connect to the exhaust pipe. only like a 16th or so but enough that it doesnt just hook up to the stock pipe. but i made a sort of collar spacer kinda thing. ill take it all apart and throw some pics up so u can see what im talking about. but yea ill try to do a quick vid, i know im saying this over and over but it sounds sick.

[ashar014]

hey dna,

im glad you like the muffler, yea its just a 1inch hollow tube muffler
its super light too, btw how does the idle sound?

im about to take my x18 out to the dorms to show a couple college girls haha

[dna316]

Lmao. yea man it sound mean. ill get to post a vid hopefully today or tomorrow. thanks again bro.

[dna316]

Oh hey and I ment to say, Those are some fancy looking stickers. lol

[Shooter]

Hey DNA...... how is that shock holding up with that extended swingarm?
I have my Fox shock ready but I fear it won't be able to stand up to all the weight I have into the bike........ I have the x18 shock ready for backup should I need it, just wondered how well it's held up for you.

[rene13]

I had a problem with my K2 smart shock being to soft and all I did was swap the springs and that was it.thinking_smilie

Its holding up just fine. I had to prety much uncompress the spring all the way but it sits fine and rides fine to. Then again im a 130lb guy.

[Ghost Rider]

Exhaust Video por favor!!!

[dna316]

oh crap my bad. i took a quick vid, but forgot to post it. ill do that today after work sorry 49.

[]-[owler]

I know this is a little after the fact, but I was wondering what you thought of this.

Yellow- find the distance from the pivot to top shock mounting and bring it down just like a compass to find bottom mounting point, buy shock accordingly to get correct ride height

Blue- new mounting point

Red- channel sides to keep the flat plate from flexing up and down

top flat plate just looks too flex prone to me:dunno:

[FiveStarSky]

I dont think the top plate matters if it flexes, its not a load bearing point, so it should be fine as in.

[dna316]

Yea so far its held up fine. i have riden a few tanks of gas allready since the stretch and it still all good.

[rene13]

I dont think the top plate matters if it flexes, its not a load bearing point, so it should be fine as in.

I f you look at my bike's swinger it doesn't have any support in that area. I have not had a problem with it. My reinforcing is within the tubing (a pipe within a pipe)

THe only thing I really had to do to mine was to weld a extra shock mount now I can run a longer shock and it will sit low or however I want it.

[dna316]

yea see thats all i think i need to do also. but im satisfied with the ride height so for now it will stay as is. but i am going to start up on the paint on the rims soon. its starting to warm up a bit. well its wierd in co. one day at 25 degrees and the next day its freakin 68. i dont get it but were having more warmer days that colder. so im gonna start up on the paint for the rims. oh duh and the swinger.
