If you mean gas leaking out the overflow tubes, it's a problem with the floats or check valves.

Would first determine exact site of the leak.

if it is a vacuum type design the petcock will have a prime position instead of an off position. It is possible the vacuum controlled valve is not working correctly and is sticking open. I had this problem. I just moved the positions back and forth and rode it until it stopped. It didn't take long.

The 77 KZ750 is not a vacuum petcock, just a crappy mechanical valve that likes to leak like a mutha.
