My bike had no speedo. I picked up a used drag specialties unit and the OEM drive gear. As far as I can tell it says I'm going twice as fast as I really am. Drag Specialties makes a 2240:60, 2:1, 1:1 gauge .....so to start with does anyone know the stock ratio of a 76 sporster with a 19" front wheel. That way I have at least a 50/50 shot at buying the next one.

I finally found the info. Here's how it seems for anyone in the same spot. OEM on a sporty 2:1 w/19" rim. If u up it to a 21" rim you'll need 2240:60 drive or so it seems. I'm going to order a new speedo to match the stock drive gear so that when the officer says " do u know how fast u were going " I can say yes............
