Petcock size

[jdp]

Does anyone know the thread size on the interstate gas tank for the petcock?

Well no one is replying so I took it off and measured it for anyone else that needs to know it’s a 22 mm so you can get any petcock you want, Pingle , V-Twin sells a Pingle copy that’s alittle better and half the price, just make sure you get the gas outlet in the direction you want and the off/on/reserve the way you want it at 22 mm .

Thanks for doing and posting that. All I had was a Shadow petcock not mounted. No Valk one to try out But I never took my petcock off the tank when I had it out, it seemed to work fine off the bike, no leaking.
