106-2161 93" KN-series engines. Generator cases

S&S 93-inch KN-series complete engine assembly. It is inspired by Knucklehead architecture with updates throughout. The engine arrives fully assembled and ready to run with an FHP420 camshaft, 8.2:1 compression, Superstock single-fire ignition and a Super E carburetor. The 58-65 style flywheel assembly runs a splined sprocket shaft and Timken sprocket shaft bearing. Rocker boxes use die-cast aluminium lower tins held under valve spring pressure with a special gasket. You do not need to press out valve guides during service. Revised internal oil lines replace the original brazed steel returns. Cases fit 48-99 mounting points. You will need a 54-65 style tin primary and motor sprocket.
