Gearcover Kit for 1986–'90 Sportster®. The S&S billet gearcovers for Harley-Davidson® Sportster® and Buell® models are available for 1986x–'90 (four-speed) and 1991–'99 (five-speed) cam chests. One gearcover features needle bearings instead of bushings for the outboard ends of the camshafts and one style uses stock style bushings. These gearcovers are not recommended for engines with stock 1986–'90 crankcases as they have no provision for the four speed style crankcase breather. Kits come with hardware and special S&S gearcover gasket. Natural Finish.
