Abstract

A method of modifying the cam drive arrangement of a motorcycle engine. The method includes providing an existing cam gear arrangement having a crankshaft sprocket connected to a primary camshaft sprocket with a chain, removing the chain, replacing each of the sprockets with a crankshaft gear and primary camshaft gear respectively, and engaging teeth of the gears so the crankshaft gear drives the primary camshaft gear directly. A specific method for modifying a TWIN CAM 88 engine, made by Harley-Davidson, according to this method, is also described.
