Considering a roller clutch for the primary clutch on my 2000 Sportsman, after a 20 mile ride, I noticed a lack of ummphh. I am looking at the AAEN set up, but have no idea what has to be done to the clutch to perhaps put one in. Anyone done this to theirs? Another erodable product on Polaris quads appears to be these clutch "buttons" that seem to have worn out after a measly 2700 miles....imagine that?
