'50 Panhead gearing guidance please
I'm working on a 1950 Panhead for a customer that's very well restored to stock-looking condition...I have it running nicely now, but it's ridiculously high geared for any practical use...First gear feels like 4th, and with a rat trap foot clutch it's not usable around any typical street use...I have not yet had the clutch or engine sprocket in view to see the actual sprockets used, but where would one expect to see the gearing on this bike begin?
The owner told me it had been a chopper before being brought back to stock, maybe thinking it was to use a smaller rear wheel??? Any guidance appreciated and thanks...

Front and rear wheels run on 16" rims stock from the factory. Sounds like you need to figure out your sprocket ratios. Coud be as simple as the front motor sprocket and/or tranny/rear chain sprocket combimation. If you do not have a manual I can look at mine to see what stock ratios are.

chopper front trans gear was sometimes a 24 or even a 25 tooth and the back drum is 51 =
stock panhead was 21 front with a side car 51 rear - with out a car its 22 on the trans 51 on the drum -- now if everything is stock we do gear them up just a bit so short hi way is ok and that is this - 24 engine sprocket / stock clutch drum - ( 23 trans sprocket ) and a 51 rear drum all with chains - done many this way never had a customer want it changed
they could have even used a 25 front motor sprocket / stock is 24 so tall gearing for around the country was a doable thing back in the day
if its a belt drive front set up then its more like a 25 then a stock 24
you never said what you have
