RIVERA'S  Ring & Pinion Kit Converts 102-Tooth to 66Tooth
Today’s big inch or modified Big-Twin motors with exotic or altered ignition timing occasionally cough or backfire during startup. This an cause broken or chipped teeth on the existing 102 tooth starter ring-gear (94 & later Harley-Davidson Big-Twin Models). To avoid this problem, Primo now offers a quality, high performance, easy to install starter-pinion gear. This pinion when installed in a 93 or later starter extension mechanism, allows the use of an early (66 tooth) ring gear. Primo’s pinion-gear, ring gear kit consists of both ring gear (66 tooth) & pinion gear, & ring gear mounting hardware.
