His name is Ron Colonna. 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 he purchased on e-Bay. The top end was patterned after photos taken from e-bay of Harley parts for sale. He 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. No casting used. Ignition: Spark. Bore: 1 5/16 in. Stroke: 1 1/2 in.The engine is large enough to produce that lovely V-twin sound.

Way COOL! Gimme one ‘an I’ll build a whole mini-chopper out of it! Even smokes like my old ’48 Pan! Wiz
Put one in a Mustang frame.
Very nice! he needs to build something to put it into now, maybe a scale Morgan!
A company called Precision Miniatures years ago sold a 1/4 scale working V-twin, along with a 1/4 scale Gypsy Moth.
Needs to be more convincing, like to see more oil leaking.
wow that is great, i want one !! all ready have a mimi chopper frame to put it in.. nice job
I am sooo lazy! peace
Naw, put it in a FULL sized frame and really freak out the crowd at Daytona this year…..
Does it break down a 1/4 of the time?
I’d replace the motor on my push mower with this and be the coolest guy in town.
Hey Ron,
I’m changing my “static” website to a Knuckle & Panhead Build Forum that’s limited to 74 cu. in. displacement.
Since your Pan fits within those confines, you’re welcome to bring your motor over there and talk about it. Sell it even. There’s an app for that.
tater tot, tater tot, tater tot, tater tot,
That is way cool, love the sound and it looks perfect. Great job!
WAY TOO COOL!!! One more thing to add to the list of “Gotta Haves”!
SWEET…………………
That’s pretty cool.
For your next trick build one full size.
There was a similar “no castings” mini panhead built By Frank Lesnet’s son (sorry I forget his name) about 20 years ago in Lakeland Fl. It also ran and sounded like the real thing. I believe it was also in Easyriders magazine.
I just started my new “standard size” 74″ Pan motor …… so yeah I know the feeling!
If you own a standard Pan and run a belt primary, stop riding it until you order a rear sprocket from Rebel Gears • Tennessee. Their ratio puts a Pan motor mildly-turning rpm’s at 45-65 mph. I just tried the rear sprocket out – motoring up and down the street. Comfy. And “Look Ma!!…. No Oil Drips.
Fabulous .!! very nice bravo!!!!!
Love that…. great work!
Guess, I could make some wheels 40%when you are ready….
How Much ?
That’s cool, better gas milage then my beefed up 48 I bet
