Instructions

The 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. 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.

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, 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.

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 initial KN93 offering is a standard compression 93 inch engine with authentic generator style crankcases for 1936-1947 Harley-Davidson® OHV big twin chassis.

KN-Series engines come completely assembled and ready to run with a preset S&S Super Stock™ electronic ignition system and Super E carburetor. KN-Series engines come with a 12 month warranty.

Generator style. Gloss Black finish.

cool looking motor, glad to see S&S keep the HD tradition of overcharging for their parts...not sure how you can justify ripping off your customers.

my 93 runs sice seven years. Great motor. Just leaky oil returns. The only thing, what went down, was the ignition coil in that time.

Can this be registered as a knuckle rather then a 2013 special construction like hot rods can be registered as the year they portray.

Awesome! And you even have a cone version! By far probably hands down the best looking V-Twin motor ever made.. & it looks like you pay for it too... too bad you'd have to prostitute yourself out in order to afford one... if they were priced like the nicer version 96in like the brand new one I just got then I'd of definatley bought one..
