So I really hate to dig up old threads, but it seemed a better idea to post in an existing thread.
This POR15 stuff.. I have a KZ750 tank and my bike has been basically built around it so there is no turning back. The original fuel valve was hitting the frame so I got a guy to cut out petcock on the original tank and replace it in the correct spot on the KZ tank. Talk about commitment..
The tank is leaking (as best as I can tell) from the area where the fuel valve is bolted to the tank. Maybe the threads, maybe not. Think POR15 after flawless prep would work for this? I'm also toying with the idea of making a gasket to go in between the petcock and the tank in the hopes that that would take care of it.
Frankly I'm at my wits end with this.
