Sportster petcock

Postby roadbum » Fri Jul 01, 2022 10:16 am

Looking for a replacement petcock for my 66 XLH. It seems all the aftermarket ones are a strait thread and the tank is a 3/8ths-18 pipe. Only enters about 3 threads and locks up because of the taper. Tried to tap tank deeper but appears to be hardened. Any suggestions?

I am in the process of switching all of my motorcycles over the Pingel petcocks.

Good way to ruin an original tank.
All the screw in petcocks from H-D were pipe taper through the early '70s. Regretfully no good replacements exist. Most are crap and the rest are worse. Pingel as mentioned is a good fix but nowhere near correct for a restoration. What are you after, function or aesthetics?
