American Prime Manufacturing Parts & Accessories

American Prime Manufacturing build high-performance clutch systems and carburettor parts for Harley-Davidson. Founded in 2018 by Ben Kudon, formerly of Rivera Primo, the Comp Master clutch kits increase friction area by almost 50% over stock and use a diaphragm spring design that bolts straight into the OEM clutch basket. They also stock parts for SU, Mikuni, and CV40 carbs.

All American Prime parts are fully interchangeable with Rivera Primo components of the same type — useful if you're already familiar with that range.
