KN-Kone motorcycle engine

The classic style of motorcycles of the past just can’t be beaten for coolness. Now, there’s a way to tap into the coolness of retro style. The new award winning KN-Kone motor combines the look of a knuckle, with the bullet-proof design and charging system of the 1970-’99 style alternator lower end. The KN-Kone motor features the S&S Super E carburetor and Super Stock® single fire ignition system.

In 2011, the KN-Kone motor won the Engine of the Year award from V-Twin magazine.

Fitment:
1970 – 1998 big twin
1999 chassis originally equipped with a Harley-Davidson® Evolution® engine. Can also be installed in earlier chassis if a transmission with a 1970 – up mainshaft is used.

Features and Benefits:
S&S Super E carburetor
S&S Super Stock® single fire ignition system
Alternator style crankcase – allows the use of modern primary, transmission, clutch components and electrical system
More simple exhaust fabrication

#310-0006 - $8,750

KN74 Generator Style Engine

Flathead Power 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. Ideal for bikes with stock drive train. Won’t break your stuff!

Fitment
1936 – 1999 chassis
Features and Benefits

Standard 74" compression 7.5:1
Authentic generator style crankcases
Super E carburetor
346 camshaft
Super Stock® ignition
Hi-temperature black cylinders and heads

KN93 Complete Assembled Engine

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.

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, 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.

Flathead Power™ 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.
