Hey spoder,I have a 02' CR 250.I 've been looking for the same thing,need more top end.Have you palyed with your jetting.Best power was with a 400 main jet(380 stock),32.5 pilot stock,move needle clip on top postion.It help with more snap at bottom,With alot more mid to top power,and more over rev.I'm very pleased now with the engine,but looking in trying a rad vavle though.Later

Thanks for the reply partner. No I haven't messed with the jetting but to tell the truth ive had it about three months and aint got five hours on it yet. What's yor location an altitude? Maybe i'll try what you suggested, got to do something this thing blubbers like a fiffteen year old clapped out 125, laters.
