THE KN93 IS A STANDARD COMPRESSION 93 ENGINE AND IS AVAILABLE WITH AUTHENTIC GENERATOR STYLE CRANKCASES FOR EARLY STYLE CHASSIS, PRIMARY AND TRANSMISSIONS, AND ALTERNATOR/GENERATOR STYLE CASES FOR USE WITH 1970 AND LATER PRIMARY COVERS AND LATE STYLE TRANSMISSIONS.

FLATHEAD POWER ALTERNATOR/GENERATOR STYLE 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. 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 SPROCKET SHAFT BEARING, THIS NECESSITATES THE USE OF A 1955-1964 STYLE INNER TIN PRIMARY COVER AND PRIMARY CHAIN SPROCKET. S&S VINTAGE ROCKER ARM COVER TINS ARE ANOTHER MODERN IMPROVEMENT. ALTERNATOR/GENERATOR CASES HAVE A 1948-1999 STYLE FRONT MOTOR MOUNT. IT WILL NOT FIT STOCK KNUCKLE FRAMES. GENERATOR-STYLE ENGINES HAVE STOCK MOTOR MOUNTS FOR 1936-1947 STYLE FRAMES, BUT CAN BE USED IN 1948-1999 STYLE FRAMES WITH FRONT MOTOR MOUNT SPACER, PART #31-2017 (INCLUDED). ALTERNATOR/GENERATOR CASES REQUIRE A TRANSMISSION WITH A 1970-UP LENGTH MAIN SHAFT, AND CUSTOM EXHAUST PIPES MUST BE FABRICATED.
