[QUOTE="sharky243, post: 1327479, member: 100273"] The only way to change the RPM's of the engine is to re-gear it. Put a smaller sprocket on the rear rim and a larger sprocket on the counter shaft off the engine. This will bring the RPM's down. The cams that are in it were probably chosen for mid to top end power. You'd be better off with the stock cams. I would definitly replace the piston, rings, cam chain, and have a real good look at the valves. You might be lucky with the bottom end, but i would check it out. A "retired" race bike usually has had the crap kicked out of it. Haveing said that, the 07' KX250F's were a fairly reliable bike as long as the maintainance was kept up on them. [/QUOTE]
