Hey RYan , I have a 2009 XP850, Got the High altitude QSC springs for the clutch kit from Adam, he said it came with 60 gram weights, my machine already had 60gram weights so I didnt buy his, found out later they were custom ground and actually were around 58 grams, so, how much for the custom ground 60 gram weights and also didnt get any of the shims with the springs, You can Pm me your answer if you want, THANKs Russ
