So I have a early style pulley and yup.. my nut came off. My bike screams at 80.. but is in my cams powerband :) anyways.. jumped to a 33 from a 32 with no problems with belt etc... also.. this comes with a new spacer that’s bigger od and narrower giving more spline surface, great idea, of course new seal, nut, nut lock plate and plate retaining bolts are included also.. now my bike feels like I have a “6th” gear.. this sprocket dropped my rpms by 110 at 80.. highly recommend for you 5 speed guys!
Impressed with the quality and design. About 1/3 the weight of original. Hard finish, should hold up for many miles. Great option to 6 speed since I travel long distances.
