I'm looking for a little more bottom end on my 2000 CR250. Anyone have experience with the FMF Gnarly on this bike? I have a Bill's pipe now, seems like more of a top end pipe. I'd like to try this before going the porting route.
Two pieces of personal advice from another '00 CR250 owner: (1) stock pipe and (2) V-Force. Both are better solutions than playing the pipe game. If you want even more low-end or high-end power, add a programable ignition to the bike. I can switch between a grunty power band for muddy tracks to a high-ouput power surge for when it dries out, all by flicking a switch. Best money I ever spent on a race bike IMHO.
