Scale Running Model Harley Panhead Engine by Ron Colonna

V-Twin Panhead
Ignition: Spark
Bore: 1 5/16 in.
Stroke: 1 1/2 in.
Two Cylinder Four Cycle
No Castings Used
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.

I'd bet a 50cc or 70cc Honda single cylinder would kick it's ass - so yeah
spot on good replica! Ha-ha. Now how about a proper L-twin motor, in the
form of a Ducati Bevel Desmo 900 SS "square-case" - now that's one you
could even SELL it's popular enough - yet at the same time it would also
make some power! Somehow I get the feeling the people who would want a
running panhead motor on their desk-top ... I'm picturing the oil baron guy
from The Simpsons - they'd probably be even happier with a FULL-size
panhead paperweight, chugging away with that distinctly AGRICULTURAL
