I know this is the wrong site for this but I dont belong to a dirtbike forum! I have a 95 RM250 Shaved head ported&polished, Pro-circuit pipes, running on 110 octane. Some guy I know has a 04 CRF450 Yoshimura pipes, the rest stock, runs 92 octane. He keeps telling me he would beat me in a drag race, but I have my doubts, and we havent had a chance to meet up in a while. which one do u think win???

 

Running 110 makes not sense if you dont have the compression for it. If you do, then you should be pretty close and probably would win on a fresh build.

All speculation here though, I'm a honda 2 stroke guy, wouldnt touch the 450.

 

Everything is fresh. the motor was built by pro circuit...

 

Maddog56 when i was at silverlk my budd didnt lose very often on his cr250.I think the only
thing beating him was those pesky banshees.It suprised him,he says his bike needs a rebuild.
