If a generator is not used on the engine, the generator location is an excellent place to mount a spin-on oil filter. High performance clutches, five and six speed transmissions, and many more drive train products are compatible with S&S Alternator/Generator engines. Fits chassis and primary on 1970-1984 Big Twin, 1984-1999 Softail, 1984-2000 FXR, 1991-1998 Dyna and 1984-1998 Touring. Installation requires either a stock 1966-1969 style exhaust system, one of several aftermarket custom exhaust systems, or a custom fabricated exhaust pipe for a Generator Shovel engine. 750637 SH93, 1,530cc Assembled alternator style engines with S&S Super Stock ignition Engine is higher than stock and fits most custom 1970 thru 1999 Alternator style single cam Big Twin frames 750612 SH93, 1,530cc, billet nose cone cover Assembled alternator style engines without ignition and manifold and carburetor Fit chassis and primary on 1970 thru 1984 Big Twin, 1984-1999 Softail, 1984-1994 FXR, 1991-1998 Dyna and 1984-1998 Touring 783161 SH80, 1,340cc, billet nose cone cover 751500 KN93 Generator style engine, 3 5/8" bore, 4 1/2" stroke, S&S 420 cam and 8.2: 1 compression 795075 KN93 Alternator/Generator style engine, 3 5/8" bore, 4 1/2" stroke, S&S 420 cam and 8.2: 1 compression The S&S KN-Series engines are very close in appearance to a stock Knucklehead engine, but offer a number of modern features for more power, better engine life, and improved reliability. Available as 93CI (more exact 92.9CI or 1,523 cc) displacement, the main improvement in design is the 1958-1965 style flywheel assembly, which uses a splined sprocket shaft and Timken sprocket shaft bearing. Although this necessitates the use of a 1954-1965 style inner primary cover and primary chain sprocket, the increased flywheel stability, strength and power handling capacity are worth a slight departure from stock. Flathead Power rocker 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, it is now being held by the valve spring pressure. A special gasket 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. Also instead of the steel brazed-in hard oil return lines used on stock tins, S&S has improved the design of the oil line for better reliability and easier assembly and maintenance. The KN series engines come assembled and complete with an S&S Super E carburetor and S&S Super Stock ignition and feature a one-year warranty. KN93 Generator style engines fit in stock and stock style Knucklehead frames with a 1954-1965 style inner primary housing and primary chain sprocket. Alternator/ Generator style engines do not fit in stock Knucklehead frames as these engines have a 1948-1999 style front motor mount and must be used with a 1970 or later style inner primary. 1876 S&S/FLATHEAD POWER KN SERIES KNUCKLEHEAD STYLE ENGINES ENGINE ASSEMBLIES (Ȧ*ȡ1ȝ (Site 417)
