jcjuhl, what are you running? stock gearing, clutching etc.. I put a Goodwin Performace clutch kit in mine and smoked a Polaris 700 XCSP in 1000'. He weighs 140 and I weigh 180. On a roll to about 100mph we were pretty close, I had him by about 1 ski length, then he started creeping on me. All that is was the weight difference. This is what worked for me up to 1000'. 54-48 helix, Goodwin blue secondary, Goodwin red primary, 287 ramps on clicker#3, 17.4 grams of pin weight. b-5 on the secondary. Good luck. By the way, stock gearing, 25-43.
