Technical / Re: How Two-Stroke Expansion Chambers Work, and Why You Should Care.

I recently heard that alot of how it works is the resonence and vibration, and that when you have a Platnum or Gold pipe it actually hurts the performance.

It's not the time spent polishing it the first time that bothered me it was every time after you rode ,even for just 30min, that sucked.

As far as I am concerned Travis has THE LIFE, he is a guy who likes to ride dirt bikes and have fun and has found a way to make alot of money doing it.  The best part is he doesn't have to deal with team managers and sponsors and a fitness schedule and a riding schedule and flying to every race and...  He wakes up when he wants and if he wants he goes and rides his bike, if he doesn't he goes and jumps out of an airplane or drives a rally car.  I don't see how it could get much better than that.

So who's to say that you can't remove material and then Scotch bright the frame?? Gee Whizz!

Funny you mention it I actually just finished scotch brighting a frame I had polished at the begining of last year.

I have heard alot of people bash Honda's case reed motor, but acording to Robert this was Robbie's favorite bike.  I will let you know when we are done with it what the final outcome is but I have been assured that a man would be very hard pressed to find a better running (true) 250cc 2-stroke.  It is my understanding (I have heard it from multiple people) that from 02+ Reynard's 250 was stronger than the factory teams.

Sorry I still haven't got pictures I had to replace the heads on a friends car, hopefully will put some up tomorrow.

Hi all,

I am new to the site, and am in the process of doing a build on a 2002 CR250 that I thought some of you would appreciate.  I was actually considering going to the dark-low power high displacement-side of motocross, even though I love the 2 stroke and absolutely loathe the heavy engine breaking of a four stroke, mainly because I wanted a new bike.  Being away from the sport for about 8 years (the military and cars) and a magazine reader you might say I bought into the hype alittle.  I had picked up this 02 cr about a year ago and it had hardly been ridden there was barley a scuff on the clutch cover, but the stock expansion chamber had a couple holes in it and performance was inconsistent.  Anyway I started talking to my neighbor (Robert Reynard of Reynard Modifications) about doing my suspension and I planed on doing my own engine work having some experience with it from when I was younger and racing alot my father and I had ported and matched the cases on all of my previous bikes.  After talking it over with him for acouple of hours I decided to let someone more expereinced with a case reed motor take the reigns on this one.

For the build.

I am having Reynard work my cylinder case and head, he is also reworking my transmission and will be re-valving and springing my suspension (forks and shock) for me as well.  I have completely tore the bike down and I am replacing the, suspension linkage, swingarm, wheel and head bearings.  I have also scotch brighted the frame, swing arm and linkage (it looks awesome).  As for the parts list, G2 Cam system Throttle, Procircuit Pegs, Works pipe and 304 shorty silencer, Vforce 3i reeds and box, ASV levers, wiseco crank and a YZ piston and a  new set of dunlops.  I am sure I am forgetting something.  I will try and post some pictures later today.
