AWESOME Scale Model Harley Engine That WORKS!!!

This engine was scratch built to a scale of 2/5ths or 40% of full size. The bottom end was taken from a drawing of a Knuckelhead engine that I puchased on e-bay. The top end was patterned after photos taken from e-bay of Harley parts for sale. I also bought a Harley repair manual that helped with the oil system. The crankcase was split into three sections instead of the usual two for ease of machining.

The ignition is solid state and I use a GM coil which fires the two plugs simultaneously. Timing is advanced and retarded with the timer body. Two rotating magnets fire a Hall effect device at the proper times as per full sized points. The engine is large enough to produce that lovely V-twin sound.

This engine was built from the ground up for a 40% scale of the real thing. The bottom end was taken from a drawing of a Knuckel head engine that the designer had bought from internet. The top end was designed by looking at photos of actual Harley parts. This engine is just barely large enough to create that unique and awesome V-Twin sound. I love this thing!
