[QUOTE="Rich Rohrich, post: 1101591, member: 16241"] The fact that it doesn't want to rev is a good thing. Keeping the revs down will keep you from breaking connecting rods. That 277 piston is way too heavy to run at the original redline using the stock connecting rod on the CRF250. I doubt it, but that's a question best answered by them. [/QUOTE]
