Gentelmen start your engines!

[swheels]

Now if i could decide what class to fit in.If i go with the 110cc i'll end up in the 125cc class.(pontentially getting smoked) If i run the 138cc then i'll be in the 150cc class.Getting smoked.LOLAnd something tells me that them boys are not coming just to play around.Unlimited mods as long as the cc's remain the same.OOUCH.I should be looking into one of those built tagawa motors???? Naaaaaaa I think i'll stay true to the under dogs.Maybe get a gpx 125cc and call it the day?

We would be in the shifter bike class aka thumper bike class.

Swheels you have a mission. If you decide to accept this mission and you're captured we will disavow any knowledge of your actions. The mission is to video-tape or have someone video as much track action as you can. People are influenced by what they see more than what they read. Posting cuts from the races will jack a lot of peoples go-fast genes. This message will self-destruct in 5 seconds...5-4-3-2-1???dunno damn I hate when the self-destruct screws upbanana.

i agree 100%. we need to offer eye candy for the people who may get into this. like the red bull thing that was posted. midbikes are a cool stepping stone IMO.

[swheels]

Oh yeah video a is a must! Even gonna try some on board camara shots

[redryderaus]

I reckon you'd be in Formula 2 with a 110/125cc, and GP85 with a 138cc. I'd go with a 125cc and race in Formula 2. twocents

Cheers,

nothing for just midbikes? is the usmgp the only PB association?

Cheers,

red Yeah i'm gonna play it safe and try and get a good 125cc.LOL Although i know theres gonna be a lot of those guys running tagawa motors.

[swheels]

nothing for just midbikes? is the usmgp the only PB association?A majority of the midbike crowd is more content with cruisin the neighborhood than a track.(not trying to offend anyone)But the few that wish to race on the tracks is not enough to get there own class.
So i'm gonna go and race up against these high dollar motors and see what i could do.

Np (aka nuttyprofessor).I think i'm gonna go with that rear uni link suspension mod for this one.I know i'm gonna rely on alot of late braking.With the brakes as strong as they are now it doesn't take much to flip the bike forward at all.So i'm gonna lower the rear alittle Plus change the shock angle which i always wanted to do anyways.boxing

[redryderaus]

No matter what you do, you're going to be competing against blokes with money to buy top equipment. But that doesn't mean they can ride it!! So get out there and ride the wheels off what you've got. You might surprise yourself! thumbsup

Cheers,

red

[The Nutty Professor]

Red I've said that before. It's the rider not the bike in 95% of the races. When the rider are equal then the small bike advantages show. Go for the suspension changes, but remember it's the rubber that meets the road. Make sure you have a couple of good tires with you. Clean your tires off after each race or practice.

[swheels]

Yeah i gotta make some tire choices.I know i will be frown upon(LOLOL)But i'm willing to ride the heck out of the bike.I refuse to hear i told you so.Those bike are no good.So with that on my mind i have to atleast be in the top running group.

[Blitz$M.Inc.$]

awsome
im gonna run in the formula 2 class
my bike will be fast in that class
i cant wait, i skipped goin to NOPI for this
hopefully we can run in the same class

[midbiker]

dunnoClean your tires off after each race or practice.
is there anything specific to clean them with?

[The Nutty Professor]

MidBiker I rushin out the door. I've got some tire stuff for you guys. Let me put it together and see what you think. I have not confirmed any of this so bear with me. I'm not sure I like this or not...STAY TUNEDdunno

[The Nutty Professor]

When Mid Biker asked about tire cleaner I realized I was holding some info you guys might want to use at VIR. If you haven't noticed I look through a lot of different sources to find stuff we can use. Some of it I think will work and some I don't and some I would rather get a wider opinion on before we use it. This is one of those. I have been reading through a couple of kart sites just to see what the tech is on the four wheel front. I mentioned in another thread (Another site) that I had read about conditioning tires. I read about it in the auto racing world but couldn't find anything until now. Well I found out the kart guys are doing exactly what I was talking about. They use chemicals to soften the rubber on their tires for better grip. They go way beyond what I think is possible on two wheels but I think the process will help the Mid's show up a few Tards and the NSR YSR crowd. When I mentioned earlier to make sure your clean your tires before each session. I found that a lot of kart guy wash their tires with Simple Green on a weekend before a race. This removes the oils on the top of the tire to allow the next step to work. They then wipe on a tire prep. That's what they call a chemical that softens the rubber of the tire. They have it down to a point that they can soften a certain tire a cetain amount using a chemical so many days out from a race or using multiple application over a certain period. With this process I can see us have buying 4-5-6 whatever sets of tires and by using the prep process having numerous different levels of grip for given track conditions. Now for what I think. It works but will it work for us? Some of the chemicals they use are what make me hesitant. The two chemicals below are preps they use from "Wal Mart". I will list a few more chemicals from off the shelf. Here are 2:

Lighter Fluid
Commercial lighter fluid has several uses in slot car racing. It can be used to clean and soften rubber tires, as a general purpose cleaner or as a mild solvent to remove the adhesive left behind when stickers are removed. Lighter fluid is one of the best general purpose cleaners available for slot car racing. Commercial products made by companies such as Ronson and Zippo are simply Naphtha. Check the label for yourself!
Tire Stick
This one's messy and is not recommend for everyone. I've included it here for those racers that insist on running glue. Often called Tire Glue, Traction or Womp Juice, it's simply straight STP Oil Treatment applied to the rear tires to increase traction. It makes a real mess of the track though and is hard to clean up. It works best on clean sponge rubber tires. A little bit goes a long way, so don't overdo it or you'll be left with a real mess on your hands.

I still want to go back and find the exact process.chief_rocka

[The Nutty Professor]

The two listed are actually from slot car guys. I cut and pasted from the wrong article. But they should work. I'm looking up the over-the-counter-buy-anywhere cleaners first. Then I list the same for tire prep. There are ready made preps but I want to see if the idea works period. Oh WARNING DO THIS AT YOUR OWN RISK!!!!!!

motorbike Let's see were the road leads us from here.

[Blitz$M.Inc.$]

in the auto world when you gotta do a tire patch you got to wipe the injury area with 'rubber cleaner'
that stuff is what you want i think

[The Nutty Professor]

Blitz I think we're talking about the same thing except they use Simple Green to clean and the others to soften.

[x19er]

I am gonna try the loghter fluid to clean and soften.

[The Nutty Professor]

Be advised that that stuff has to sit on the tires for a couple days then whatever sitting on the top has to wiped off. Remember also at your own risk we need more time to figure this out.

[midbiker]

is the $5 fee to racers for the gate fee in addition to the racing fees or just the racing fee? looks like some fun out there. please get video!
motorbike

[Blitz$M.Inc.$]

i will have my wife filming
im sure the others will too
i dont think they will allow Swheels onboard cam

[swheels]

You might be right but i'm sure i can sneak it on after tech inspection.You can't see it unless you look just underneath the lights.LOL SSSSHHHHHHHHHhhhhhhhhhhh.dunno

I've got all the measurements of the progressive-rate linkage off the VTR1000. I'll try to get a drawing done later today for you, swheels. I'll scale it down a bit to suit the midbike based on swingarm length.

Cheers,

redThat'll be cool Red..Boy i'm hoping that linkage work out for the better.I got one that i took off of my old 2stroke midbike.I still haven't put it on yet.Poke12

[redryderaus]

I'm designing that linkage into my aluminium "super mid-frame". I know it worked exceptionally well on the VTR when I was racing it so it will just be a case of scaling it correctly and then getting the shock to work with it.

Cheers,

[swheels]

I'll post a pic of the one i have.

[kevin@holeshotz]

As the second top rider on chuck shories team "fastline" (chuck is the president of USMGP) i will not mind answer these questions that have come up (most were given incorrect answers).

Just like most leagues, if there is enough to make a grid, we will make your own class. Though if its only one or two of you, you will go into Thumper 125 and 150 as the vehicle permits. So bring your friends, and you wont get your ass kicked by me and andres on CRF150Rs lol.

Yes, there is a $5 gate fee which will get you in the whole weekend, unless you break your wristband. Last race at VIR was $125, but since the amount of attendance at this race, it will most likely be in the $75 range (dont qoute me on that).

As for "prepping" your bikes for the races, i would take electrical tape and take over all of yours lights, so they will not fall out(not just the edges, the whole light). I was told 17/36ish would be suitable, but bring alot of gearing as the track is very unique (tight, long straight, uphills, off camber tires).

If you have the availability to get new tires on your bike, DO IT. The stock tires will not hold up on the off camber turn.

I raced this track not to long ago, very smooth, so don't be shy to stiffen up the suspension up a bit. Its very technical so bring your A-game in the cornering department. There is a long straight but half of it is uphill, so you don't really open up until the down hill (unless you are on a open class). So best of luck to you guys

So best of luck to you guysThat sounds great!But the rules and classes i copied and paste them right from the web site.So if theres anything wrong there.That's where i got all my info from and they should correct that then.Cuase i'm struggling trying to fit in a class.

[Blitz$M.Inc.$]

well ive never even raced before but im going to smash you all!! haha lol jk
really im just gonna have fun try to go fast and not wreck

[kevin@holeshotz]

That sounds great!But the rules and classes i copied and paste them right from the web site.So if theres anything wrong there.That's where i got all my info from and they should correct that then.Cuase i'm struggling trying to fit in a class.

What you posted was correct



Formula 2
Two strokes up to 65cc, 4 strokes up to 125cc. Bikes may have unlimited engine mods but must not exceed max displacement.

GP 85
Two strokes up to 85cc, four strokes up to 150cc.

Thumper 125
Four stroke machines only up to 125cc under. Unlimited engine mods, but can not exceed 125cc. Examples: XR100, TTR125, DR125, Spec Bike

Thumper 150
4 stroke machines only up to 150cc maximum . Unlimited engine modifications, but must not exceed 150cc.



You guy swould fit into those four classes. ALTHOUGH, if enough of you show up, we would run you all in your own class. If alot of you show up, we will split the classes into two, F1 and F2 midbike classes. F1 would be up to 150 f2 would be up to like 125cc.

So get your friends to come if you want it to be most fair and most competitive. I look forward to meeting you all (i will be in chucks pit riding a honda crf150r. If im not on that im on chucks POS pocketbikes)

[kevin@holeshotz]

well ive never even raced before but im going to smash you all!! haha lol jk

Good you coming, wrecking is a good thing, it tests your limits and allows you to become a faster rider. Wrecking at VIR is the best part of it, especially when you hit the wall.

PS- i got to sign the wall after this happened:

Man i can just imagine what kind of engine mods those guys are running.I'm not going down without a fight!boxing11Well maybe in a turn.skull what are you guys running for tires? I would suspect a soft compound.(cooler weather)Man thats alot of track.Makes it easy to go around a person

Dont worry about engines out here. I beat a built 125 on a 4.2hp pocketbike in the rain. Hes a pretty good rider, sitting in first in Thumper 125.

Soft compound will due best at VIR period. If it were dry and 90, you won't like looking at your tiers at the end of the weekend, but i doubt it will be that hot or that dry.

[kevin@holeshotz]

Hes barely out of this pic, but it was after i passed him (corners win all once your in front)

And yes, i realize i barely fit on that bike. I never thought of a bike that small, i shouldnt listened to htem when they said "The stamas mini is the smallest bike on the market"

[king]

kevin@holeshotz, are you doing this event or do you just race or both? great pics. what % of traction is lost on a wet track. if any.

[king]

also, isn't it really cold then or not. dunno i never been to virginia.

[swheels]

And yes, i realize i barely fit on that bike. I never thought of a bike that small, i shouldnt listened to htem when they said "The stamas mini is the smallest bike on the market"Well it looks like you was riding the heck out of that bike.every time i tried i would crash in the turns.

[redryderaus]

Here's the drawing, swheels. I've included a few photo's of it as well. All measurements are in mm and are from hole centre to hole center. The green line in the drawing is the centre-line of the shock absorber.

Chuck Shorie, the guy how coordinates and runs the USMGP (the club holding these events) is my sponsor on pocketbikes. I help setup and stuff like that, but i do not run it. I will be racing in it though and helping out here and there.

I was on intermediate tires, so they were a soft compound with light water rebelling tires (whats the proper term?). I was just as fast in the rain then in the dry on the stamas bike.

At midohio in August, Jimmy D the top pocketbike rider rode faster then anybody on slicks in the rain. everyone else had rain tires on, if thats not skill then idk what skill is. lol

also, isn't it really cold then or not. dunno i never been to virginia.

yes it will be cold, not 30s but probly 50s or 60s. I will check an almanac to see what weather in that area is really like on november as its nears mountains.

Well it looks like you was riding the heck out of that bike.every time i tried i would crash in the turns.

When you say "you crack in the turns" what do you mean? Front slides? rear Slides? your going to slow and tip over? If its one thing i love to study its body position, PM me how you wreck normally and i will help you out.

Take a pic of your rear tire (looking at the tread). I wanna see something.

Do they make upgradable rear sets for these things? Is there a way to raise the pegs?

Boy do I wish it could get down to the 50's or 60's out here.
It is supposed to hit the upper 90's over the weekend here in the Phoenix area.

If yours pegs were hitting on a PB then you were riding the sidewalls to hard and not leaning off enough, lol. I have to try to get my ankle on the ground, lol.

If you have good tires on your x18, you should be decent at VIR. Do you mind if i take your bike for a spin? Riding a midbike setup for racing might be different the the stock shit i rode.

I have to try to get my ankle on the ground, lol.

in the pics are you wearing low top shoes. would you need different shoes? just wondering because i dont or havent raced.

rolleye0010Here's the drawing, swheels. I've included a few photo's of it as well. All measurements are in mm and are from hole centre to hole center. The green line in the drawing is the centre-line of the shock absorber.

Cheers,

redThats great stuff Red.The one i got is made out of steel.What angle do you plan on mounting your rear shock at? I'm still thinking about minds.I'm also thinking of designing a top shock mount that will allow me raise or lower the rear,possibly even change the shock angle.I got get together with one of my buddies so he could weld it up for me.I don't trust my welding skills with something like this.

[stuntnx7]

i thot this was a midbike site and not for pb's at all. ive been here 2 seconds and i see a pb

i think they were talking about midbike racing back east and pics were posted of a crash after crashing was mentioned.peace_symbol

[midbiker]

I also think the pics were at the track that this thread is about. VIR. peace_symbol

[The Nutty Professor]

It was posted to show the track. The guy posting just happens to be a PB looking at the MB game...I think.

[X7rocks]

what tech inspections must we go through swheels?
like stuff toward motor leaks?
hydro leaks etc?

[swheels]

what tech inspections must we go through swheels?
like stuff toward motor leaks?
hydro leaks etc?I think there are doing a walk around inspection.But if anything is leaking that might raised there concern.Also theres a chance we might get our own class.Kevin said that if theres enough midbikes to fill the grid then we'll all be racing with each other.But if theres not enough we'll all be in the 150cc class.I think it will be cool if we get our own class.But i'll take the action no matter how it comes.rock2So if Doug@xmr comes and bring his guys,you(X7rocks)Blitz and myself Plus i'm still trying to talk the Thelog32 into going and maybe my boy from ct(If he gets on a have way decent bike we may all be in trouble)So more than likley we should get our own grid.If we get our own and throw down some great lap times.Theres a chance we might be able to show that these3 bikes can be raced.Then get more people interested.thumbsup2If you can find out how many guys are coming from the the Doug side.

where is this race at and how far is it from knoxville,TN and how much is it to race

rolleye0010Thats great stuff Red.The one i got is made out of steel.What angle do you plan on mounting your rear shock at?

On my design the shock is leaning slightly forward. If the shock is on too much of an angle it would introduce a non-linear movement the opposite of the pro-rate linkage.

A pro-rate linkage works by creating a non-linear movement in the shock, hence "progressive-rate linkage". With the swingarm near it's normal position the shock only moves a small amount for a given amount of swingarm motion. As the swingarm moves up, the faster it has to move the shock. This allows the suspension to soak up small bumps near it's normal position without the rear wheel skipping. As the load increases it has to compress the shock faster. In effect, the rear shock becomes stiffer. This is what is needed under high cornering loads. It can help prevent the shock winding up and producing the dreaded "high side".

By leaning the shock a long way forward the geometry of the setup produces a non-linear movement that has the shock moving slower as load increases, effectively cancelling out the pro-rate linkage.

Something to be aware of with a linkage like this. You are adding several pivots all of which will contribute to slop in the system. This is uncontrolled movement which is detrimental to handling. So make sure all pivots are as slop free as possible. I'm looking at using bearings in mine as even a well machined bush has some slop.

Steel is fine for the linkage. Steel doesn't fatigue as easily as aluminium. An adjustable top mount is a good idea as ride height is another factor in handling.

Cheers,

red

All the information you possibly need is on the first page of this thread, i suggest reading it.

As for mapquesting how long it takes, i think thats a job for you to do.

I posted PB pics to show the track and to show myself hitting the wall, only trying to help you guys out.(sorryrolleye0010)

Tech inspection will go as page 10 says. yes i know this is a link to a different clubs rules but we will do the same for your bikes. Do not remove your lights, just put electrical tape over them.

Kev what are you saying sorry for? We got it and I would like more track photo's because it helps those of us who want to race see a little of what we're getting into as far as the track is concerned. And Kev you said the track is real smooth? Are you sucking the guys in thinking_smilie or is that gospel cool_shades. Hey I won't blame you if you ain't work the head as well as the bike you lose.

redGreat info Red.All that your saying is all i was hoping for.Hah this just might give me the egde i'm looking for plus a few other things i have to keep under raps.I know what i'll be doing for this weekend.

[Midbike Racer]

Keep the pics coming Kevin.
It's a track that hopefully a handfull of midbike racers will be on and it helps to see more of it.thumbsup2
BTW, I asked my wife about the 5000 round trip to race but my wife said no.rolleye0010
I hope all the midbikers can get some good pics to post here. Maybe even some video footage.

http://www.ohioysr.org/Rulebook2007.pdfYeah more pics.They look great.I watch the vids i pull off of youtube of the go karts onboard shots.I would love to see some vids of you guys getting around the track.Hey i got one of those cheap onboard micro camsWould there be power in the pits.I'll bring it with me if i got a place to hook up the tv to see the view.It's a cheap one but it work pretty good.

thanks for the info swheels
my bike has a little leak problem with oil as it runs but not as much as it used to but maybe it will slide?

as far as I know, it is a safety issue. if your midbike is leaking all over the track, that is a problem. i would wonder what ammount of dripping or leaking is acceptable.twocents

[swheels]

jb weld. its almost as good as duct tape.

If there is any oil leaking you will not be allowed on the track, that will not only make you slip, but everyone else. Read rulebook for the OYL, page 9-10 will explain everything. You will need to make catch cans for all your overflows.

as far as I know, it is a safety issue. if your midbike is leaking all over the track, that is a problem. i would wonder what ammount of dripping or leaking is acceptable.twocents

There is no amount that is acceptable, but you are correct, it is a major safety issue.

Bumps i don't mind the bumps although i know the motards will role over them with no problems.

Yeah more pics.They look great.I watch the vids i pull off of youtube of the go karts onboard shots.I would love to see some vids of you guys getting around the track.Hey i got one of those cheap onboard micro camsWould there be power in the pits.I'll bring it with me if i got a place to hook up the tv to see the view.It's a cheap one but it work pretty good.

Bumps? What bumps? I am not kidding, this track is mint. I did not find one bump on it (well going through the first chicane i kept hitting the damn curbs), not a gimic, the truth. Bring your camera, there is power in the barn if you need it. The staff there was great, i will post qoutes on here of compliments if you need them (from the last race there.)

Keep the pics coming Kevin.

I got a bunch of pics, i will put some stuff together for ya so you get a good idea of the track and the elevation changes/off camber turn.

Sarcastic sorry (hence rolling eyes). Smooth as J.Lo's ass my friend, no joke.

As far as the lights goes i have the lens in but no lights.I'm gonna take the lens out and make like some fiberglass lens and do the same for the rear.Do you rember the some of the lap times.Don't have to be actual just an estimate.

We did not use transponders when we were there, though here is the mylaps for SEMRA round 7 at VIR: This is the formula 2 class, which is what bikes you will be racing (if you have a 125)

its leaking from the base of the cylinder...
looks like im gonna have to take something off and add a gasket...
kev i gotta order something from you then

[king]

very cool video. the elevation changes look great. thanks!thumbsup2

[X7rocks]

yes swheels i have
i even see a TINY gap between the metal gasket and the cylinder im gonna possibly have to get another base gasket inbetween that spot since it has one as the main base

[midbiker]

that track looks great. thanks for the vid.thumbsup2

[swheels]

Ok i saw a post from Doug@xmr on the other forum.He said he's got a solid 6 guys with good bikes and a few more possibilities.Holy SHHHH!!!!!!!!! we could make history here.

Roll call Doug@xmr and his 6(and a few more possiblities),Blitz,7rocks,swheels and possibly one of my friends from CT. Go superbikes! We'll show those guys!

[X7rocks]

sweet
hey swheels have you seen dougs x12? it seems like one powerful bike

[swheels]

sweet
hey swheels have you seen dougs x12? it seems like one powerful bikeI've seen the pics it looks real mean and them boys do great work!I'm pretty sure those guys are coming to kick butt.moon1

[X7rocks]

hahaha for sure
ima definatly send my bike to there shop for some fine tuneing though
how about you man?

[kevin@holeshotz]

Get ready to race me in GP85 boys :-D

Oh boy your in for a roral ass kicking a la kevin.

[Blitz$M.Inc.$]

to be clear, it is $5 for spectating
and how much exactly to enter a bike and race?

that is also my main guestion
but weee road with XMR sunday
they got some great riders on the X12 bikes

As i've heard from Kevin.It was 75.00 dollars and i'm assuming that's for the whole weekend.

This might sound like an off topic post but if you think about it it's not. How do you capture a video from youtube and place it in your computer. I want to pull the video's down for future reference anytime anywhere without having a hookup. I don't have an aircard only WiFi and in the boonie's on a track you ain't getting a signal. That would allow me to look at old footage and study lines during a weekend. Missing a second? Check you old files and maybe you'll find it? Ever advantage I can find...I played football to and having a good playbook wins. cowboy Older sometimes means smarter. Not always but I use to be real stupid and I got hurt A LOT.
