I'm currently in the process of de-rusting the tank on my K2 750, and to plug up the tank I need to know the thread size on the screws that hold on the petcock. This is the bike with the two-screw petcock on the right side. Parts fiches tell me it's a M6, but does anyone know the pitch? 1 or 1.25?
I've got M6x1.0 right now, and they thread in a bit, but seem to bottom out. HOWEVER, my tank is in pretty rough shape, with lots of gunk on the threads. I could clean it out, but I don't want to re-tap it to the wrong pitch.
Anyone with any insights?
