Description for KN-Series Engine 

KN-Series Engine

Fitment Note: Will also fit most custom applications using 1970-98 alternator style primary system.

• The KN series engines are very close in appearance to the 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″ displacement, the main improvement in design is the 1958-65 style flywheel assembly, which uses a splined sprocket shaft and Timken sprocket shaft bearing

• Although this necessitates the use of a 1954-64 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

• Flathead Power rocker arm cover “tins” are another modern improvement

• S&S has improved the design of the oil lines for better reliability and easier assembly and maintenance

• KN series engines come completely assembled and ready to run with a present SS Super Stock electronic ignition system and Super E carburetor

• KN Series engines come with a 12 month warranty

• S&S engines are shipped without oil
