The 01 runs very good. My friend Scott Hofman has been racing one at the local races, got 3rd OA up at Huntersville. I would have to ask him what he did for jetting but it wasn't much. The suspension he put in stiffer springs in the front (he's around 180lbs) and that was about it. I was really happy with my 00 250, only rejetted it and put in heavier springs also. I have it for sale right now, just picked up my 02 200EXC last night.
Are you coming down to Stratford, IA this weekend? should be fun!
