{"product_id":"s-s-93-kn-series-engines-generator-cases-mcs-531588","title":"S\u0026S, 93\" KN-series engines. Generator cases","description":"\u003cp\u003eComes with an FHP420 cam \u0026amp; 8.2 compression ratio. The S\u0026amp;S KN-series (Knucklehead style) engines come very close to the original but it is not a replica engine. A number of improvements\/changes were made. It comes with 48-99 engine mounts and will not fit OEM Knuckle frames. A later, 58-65, style flywheel assembly is used, with the splined sprocket shaft and a Timken sprocket shaft bearing for increased strength. Therefore a 54-65 style tin primary and motorsprocket must be used. Rocker arm cover 'tins' are also improved over stock. The lower covers are made of die-cast aluminum, and instead of being held in place by the valve guide, they are held down by valve spring pressure. A special gasket on the bottom of the lower 'tin' provides a good seal and easier access for servicing, since the valve guides do not need to be pressed out in order to remove the lower covers. Instead of the steel brazed-in hard oil return lines used on stock tins, S\u0026amp;S has improved oil line design for better reliability, access and assembly. Engines come completely assembled and ready to run with an S\u0026amp;S pre-set Superstock single fire ignition system and S\u0026amp;S Super E carburetor. \u003cbr\u003e\u003cbr\u003eNote: Crankcases come with 48-99 engine mounts and will not fit OEM Knuckle frames.\u003cbr\u003e\u003cbr\u003eNote: Special Order Product only.
