K...I have a 3 "belt drive on my shovel..If you've ever tried this setup w/ the stock or 5 finger clutch you know its difficult if not impossible to keep the clutch basket from "walking out" while the clutch is pulled in..So after living with it for a few seasons i decided to up grade the clutch..2 options I was considering were Rivera...and Barnett Scorpion..both made for Shovel/Pans..I heard from a friend the Pro Clutch worked great..but was a "little noisy". I bought it..it wasnt cheap ..like 550$ . Installed easily and works PERFECTLY..BUT..this clutch rattles like a MF.. You can hear it from miles away..I didn't think it would be an "issue"..my bike is fairly loud w/ the pipes, how loud could it be?..Well put it this way..if you took an empty spray paint can and attached it to the clutch w/ the ball bouncing around inside the can..thats pretty close..And its the kinda noise that hits you the wrong way..riding/ stopped/ engaged/ disengaged...noise!... when you pull into a parking lot or bar w/ other bikes in it everyone will turn and say WTF is that? Is there something wrong there? BUT as I said it works PERFECTLY..Just a heads up to someone considering this "upgrade".It bugs me so much I am considering swapping for the Barnett.
