[QUOTE="whenfoxforks-ruled, post: 1361278, member: 73147"] I was unaware of any top end changes in the crf 450 ever, that made any drastic change to the power. Changed the exhaust flange angle a couple times, compression, decompression, crank center back/lower, made the valves smaller, and the ap adjuster, finally, just before efi? Most of their changes wrapped around the frame, or making the power hit slower/more usable? Most used ones, and some new ones, just need a properly performed engine rebuild and jetted. They ARE TOO fast for closed course competition. [/QUOTE]
