They work good a Ski-doo. If your asking if it will bolt on a yamaha and work better? No, won't fit the tapper. The cat billet cover is only to run a TRA spring in a cat. I don't see any need for that if your running a cat clutch because they have LOTS of spings for cats with a stock cover.

There is some TRA's with the right taper but I think they run a narrower belt. The TRA in stock form grips the belt harder in the early shift range but won't fully shift out on the big end. For what it is worth the Yamaha clutches can be made to work very well over the entire shift range...................SRXtreme
