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.

Do you manufactured it? I'm very curious about the data, do you estimate
torque, power, RPM and consume? Sorry about the english, I'm brazillian and
I don't write very well.

Oh my Go# How did you build this. That is so great. I had a 59 panhead and
it looks just like it. You must be a master at the lathe. Very good

Hi Ron is it a true radial? It sure sounds like it. Great video!

Автор Dave Litten ( назад)
Sounds great, here in Denia, Spain, we have a Harley club, so I´m used to
them throbbing and low-end grunting around the streets. Since it is 40%
full size, then if you slow the audio track down by the same scale ratio -
I wonder if it sounds like a full size machine? Anyone tried?

I see someone beat me to the punch and asked if it leaked oil. All joking
aside, that is an absolute fantastic job. I can truly appreciate the work
that went into it. Thanks for sharing your creation with us.

Why is it only running on one cylinder. One exhaust pipe is blued with heat
and the other is clean. Smoke only coming from the heated blue exhaust.

don't let harley see how underpowered and inefficient this engine is,
they'll want to build a bike around it.

The guys who hand-build these masterpieces are genuine craftsmen. They can
be equated to the master Italian sculptors of the 15th Century...

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

Probably more reliable than the original!
