I am so tired of ppl saying "It needs this and that."
BS!!!!! It's a 2 stroke. granted there are quite a few things that can be done to be competitive, but build and dial in the suspension for the rider, add some good reeds, polish the ports, good pipe and a Phathead and ride the SOB.
A 2 stroke is already built to race, it only needs minor refinements. A 4 stroke is a thumper, made to ride around the woods or race an average class but needs major work to to be all-out race ready. Send me a new YZ/KTM and $1,000. I guarantee the bike will make it through a race.
People are putting too much effort into prepping a 2 stroke for racing. They're fixing what ISN'T broke.
WHy is it you can take a brand new 2 stroke from showroom to track, run the living hell out of it and be fine. A 4 stroke has to have a certain amount of break-in time, oil changed after break-in peroid, etc, etc.
DUUUHHHH. IT'S A RACE MOTOR!!!! It's built this way!!! The absolute, only thing I'd change internally would be the shift drum. Many pro racers (upon my studies) like a very small Neutral detent so it isn't accidentally hit in a race.
