here's a few shots from oak hill....since we only made the first half...only two of our riders got pics taken, me and level5.

THANKS TO OUR SPONSORS AND SUPPORTERS!!!! MOTORCYCLES UNLIMITED IS OUR MAIN REASON FOR BEING OUT THERE!!!! THANKS PATRICK AND CREW! If it weren't for you guys, our bike would've probably blew the engine instead of the tire. Thanks for the quick and great service you guys do on our bike. Thanks to our riders who did their best out there. Thanks to my family and friends who wished me luck, we'll take em down next time.

how much does it cost to build a bike that will be competitive i know 90% is rider but what didyour build cost

i went a lil overboard on my suspension....but my build cost approximately $3000 on top of the $1200 i payed for the bike. that is no engine work....wheels, tires, front fork conversion, disc brake in front instead of drums, racetech springs and valvework in forks

there are cheaper alternatives to building one though, that can still be competitive in mini races. i just didn't like the front forks and front brakes of OEM crf/xr100's

what class are you trying for? it really depends alot on which race you wanna be competitive in

houseofpaint

10-02-2007, 08:47 PM

btw, that's just what i spent.....but you can probably build a decent one, and be pretty competitive for around $1,500 on top of the price of the bike

both of u looked good out there, looked like a good battle with that other bike for a while.

i never understood how a bike can lean so far over and not tip over!

For example look at the first pic with those SKINNY! wheels....that's crazy!

yeah, me and that red ysr50 was going at it for 45 min before i switched riders....he'd pass me on the straights, but i'd catch him everytime coming into the corners. next time, hopefully i'll find a better place to pass him so he won't have a chance to come back in front.

it's gravity, rubber, power, and a few other things i don't quite understand....the bike will actually tip over if you let off the gas, by staying on the throttle, it kinda pushes itself through the turn....hard to explain, you kinda feel it when you ride it.

Centripedal force. The wheels act as gyroscopes to keep the bike up. It wants to stand up.

Tony, you said in Katy, the front end was diving down real bad. How is that front end now? Did you do something to it?

yep, patrick and his crew worked their magic and got it right. feels great now. didn't even lowside 1 time at Oak hill. HUGE improvement. can't wait to get back to katy now. :D

Great!

Nice inspiration for our bikes but I won't even touch my bike until getting ready for next year. My recovery is taking forever and mods for my bike are absolutely not in the budget right now. :sad7:

yeah this guy put a motogp front end on it.. :keke:

jk.. good pics man... pic them up from Irwin? he takes nice shots.

Centripetal and centrifugal forces both share the same magnitude, just opposite direction. I believe that centrifugal forces are the reaction to centripetal forces (all forces have an equal and opposite). It's confusing, and been a while since I studied angular momentum, so I'd give both of them :thumb:.

Well according to Newton, every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it. When travelling in a circle, there must be a constant force pushing that body towards the center of the circle. This force is centripetal (center seeking).

Now Mr. Newton's third law states that every action there is an equal and opposite reaction. For centripetal forces, the reaction is centrifugal (center fleeing) forces. So they have the same magnitude, just opposite directions.

I hope this helps out a bit. Maybe my next lesson will involve examples.

Give examples it would help. I am a visual person without mental pics, I will be lost.

i'll dig up a physics book when I get home, and maybe start another thread on my findings.

heck, maybe I will do some calculations too and do a writeup!

anyhow there's way more involved than just the centripetal and centrifugal forces and the gyroscopic effects of the wheels. There's gravity and friction and many other factors that come into play in why the bike doesn't slide out.

Just think about super-elevated roads vs. non super-elevated roads.

I believe that centrifugal forces are the reaction to centripetal forces (all forces have an equal and opposite). It's confusing, and been a while since I studied angular momentum, so I'd give both of them :thumb:.

centrifugal is the opposing force created by the centripetal force (Newton's 3rd law). Also centripetal force is only created when traveling in a curved path (hence taking a curve).

To make it simple, when in a corner, the force trying to make you fall(Centripetal) is equal but opposite to the force keeping you from falling(centrifugal).

It gets MUCH more compicated when you start including the forces of gravity as well. If you draw a real thorough diagram you'll see that more than just 2 forces are pushing/pulling, but in the end all forces acting on an object have an oposing force. The opposing force of gravity is called the normal force, which is basically the oposing force keeping you from flying up or being crushed when you're just standing there.

Ok im off the soap box, time for lunch :D

okay, all you guys confused the living crap outta me. it's the jedi force that keeps me up, and it does a good job most of the time....:rofl:

i bought the letters from michael's....and sewed them on myself, but i'm gonna strip them off, cuz i just bought some new patches to sew onto the suit. needle and thread is your best friend :thumb: if you rely on those sticky patches, they'll fly off sooner or later.

Simply, have you ever had a gyroscope for a toy? Notice how when it's spinning it won't fall over until the speed of the spinning disc reaches a slower speed?

You have two gyroscopes on the bike :thumbsup:

:nod: Okay, I got the gyroscopic and the centrifugal force. I did some reading about the centripetal and now my head is spinning.

maybe for the water cooled bikes.

edit: or I guess it would apply with gasses too (flow through pipe). but that has nothing to do with bike stability (i don't think)
