Motorcycle Storehouse / S&S KN 74" engine

Motorcycle Storehouse / S&S KN 74" engine


The S&S KN-engines are made to resemble the OEM Harley Knuckleheads. Although many parts will fit a stock Knuckle, not all parts are identical to the original. These engines have been on the market for a while, but all were equipped with 3 5/8" big bore cylinders and a 4 1/2" stroker crank. For the first time S&S has produced their KN-engine with the stock late Knuckle 74" (1200cc) capacity. They have done this using the stock 3 7/16" bore x 3 31/32" stroke and setting the compression ratio to a very moderate 7.5:1. This engine will not win dragraces but is expected to run much longer than its stroked equivalent. Ready for a brand-new KN-engine, complete with Super E carb and Superstock electronic ignition, that will do the distance?
Now is your time to act. For more information on this and other S&S engines you can contact your local Motorcycle Storehouse dealer.
