Replacing the 9 tower clutch with the 6tower (0746-424B) on my sons 03 MC. What weights are needed and what spring is best? He weights 250# and the sled has Stock pipe with Jaws front dump can. He rides at 2000' mostly with trips to 4000' and 8000'. The clutch came with cutler 60g arms and silver spring and a bag of different length set screws. Any suggestions welcome, thanks, Lorin
