I am working on a 2001 mxz 600. I need it to beat a 2002 ZR 600. Right now both are stock. The MXZ get the jump out of the hole, but in mid-range (60-70) the ZR catches the MXZ and then walks by. I don't want to gear or do clutch work for top end that will hurt low end bad, as most of the places we ride you don't see top end anyway. I was thinking of gearing down a bit and playing with the clutches. If we can get another couple sled lengths out of the hole, the ZR won't touch it. Any suggestios as to what I can do for gears (if I should at all) and what I can do as far as clutching?? Any help would be appreciated. We can't let the cat win!!
