I'm having a serious issue trying to find a petcock that fits the bung on the stock tank. I've ordered a couple and had to return because the nut is too big for the bung. The bung appears to be 16mm, but honestly seems closer to a 5/8-18 fine thread. It appears the PO replaced with aftermarket, and the other aftermarkets I've found to replace 16950-341-671 don't seem to fit either. I need help! Does anyone know the actual nut size for the stock '76 CB750F SS tank and where I can find a petcock with the that nut size?
Any help is appreciated...
