Float problem and/or petcock problem?

[TwistedKestrel]

I'm asking this question mostly because I'm lazy. If I have a carbureted bike with a vacuum operated petcock, and fuel is very clearly making its way into the crankcase when the bike is parked... do I have one problem, or two problems? Is it possibly normal operation for the petcock to still trickle fuel into an empty carb when the bike is not running?

repair petcock or get a new one, it should not leak or allow fuel to flow if bike is not running and creating a vacuum

That's what I thought... damnit

If its for your GS500, Suzuki doesn't show any internal replacement parts, just a whole petcock.
Check with your local dealer/repair shop and see if there's an aftermarket kit available OR a manual petcock that would fit.

My SV650 had this issue. It was a stuck float.

You have two problems.
The petcock should seal when the bike isn't running, and your needle valve leaks or the floats are too high.

I had this same issue with another bike. Stick float
