Product Description
S&S KN93 Complete Assembled Knucklehead Engine
The S&S KN-series (Knucklehead) engines come very close to the original but it is not a replica engine. A number of improvements and changes were made to this engine.
It comes with 48-99 engine mounts and will not fit OEM Knuckle frames. A later, 58-65 style flywheel assembly is used, with the splined sprocket shaft and a Timken sprocket shaft bearing for increased strength. Therefore a 54- 65 style tin primary and motorsprocket must be used. Rocker arm cover 'tins' are also improved over stock.
The lower covers are 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 on the bottom of the lower 'tin' provides a good seal and easier access for servicing, since the valve guides do not need 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 oil line design for better reliability, access and assembly.
Featuring a FHP420 cam and an 8.2 compression ratio, these engines arrive fully assembled and ready to roar. To ensure optimal performance right out of the box, each engine comes equipped with an S&S pre-set Superstock single-fire ignition system, as well as an S&S Super E carburetor.
The KN-Kone engine is identical to the KN but comes with an alternator crankcase which is adaptable with all 70-99 Shovel & Evo Big Twin transmissions and aluminum primary covers.
Note: Crankcases come with 48-99 engine mounts and will not fit OEM Knuckle frames.
