Aside from the much larger 93 inch displacement, the main improvement in design is the 1958-1965 style flywheel assembly, which uses a splined sprocket shaft and Timken\u003c\/span\u003e\u003csup\u003e®\u003c\/sup\u003e\u003cspan\u003e sprocket shaft bearing. Although this necessitates the use of a 1955-1964 style inner tin primary cover and primary chain sprocket, the increased flywheel stability, strength, and power handling capacity are worth a slight departure from stock.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003eRocker arm cover tins are another modern improvement. The lower covers are actually 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 and o-ring seal on the bottom of the lower tin provides a positive seal, and is much easier to service if needed, since the valve guides do not have to be pressed out in order to remove the lower covers.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003eInstead of the steel brazed-in hard oil return lines used on stock tins, S\u0026amp;S has improved the design of the oil line for better reliability and easier assembly and maintenance.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003eThe initial KN93 offering is a standard compression 93 inch engine with authentic generator style crankcases for 1936-1947 Harley-Davidson\u003c\/span\u003e\u003csup\u003e®\u003c\/sup\u003e\u003cspan\u003e OHV big twin chassis.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003eKN-Series engines come completely assembled and ready to run with a preset S\u0026amp;S Super Stock\u003c\/span\u003e\u003csup\u003e™\u003c\/sup\u003e\u003cspan\u003e electronic ignition system and Super E carburetor.
