| Andrews sprocket pulleys match 1994 style design. This arrangement has the advantage of 50% longer internal spline length compared to the early design. New style pulleys will fit both early (1985-1993) and late transmission shafts. Overall Belt drive ratio changes of 3%, 6% or 9% are very noticeable to a rider! All ‘85- ’93 pulley kits have new style spacer, lock ring, retainer bolts and seals included as part of the kit. Pulley kits for '94-up must use original stock seal and lock ring. | ||||
