The main improvement is the 1958–1965 style flywheel assembly using a splined sprocket shaft and Timken® sprocket shaft bearing. Rocker arm cover tins use die-cast aluminum lower covers held down by valve spring pressure — easier to service and a more positive seal than stock. Authentic generator-style crankcases for 1936–1947 Harley-Davidson® OHV Big Twin chassis.
