KZ400S Petcock 27 May 2021 22:53 #849103

PoodlePuncher Topic Author Offline User Posts: 63 Thank you received: 8	I pulled the trigger on the CB750 petcock from Dennis Kirk and it seems to fit nicely. As i feared, the gasket on the old petcock was petrified. if the new one didn't fit, or i had just taken it off to measure, there is no way it would seal to the tank again.

I've never used an entire CB750 petcock as a replacement but if it fits...
I just rebuild my petcock with the CB750 4 hole gasket. If the rubber oval seal to the tank is leaking that can be replaced with an O-ring of the suitable size.
