Replace/rebuild the petcock and the float valves in the carbs.
@ducatiman for parts.

We know the float valves are bad because there is fuel in the oil. They are letting fuel past and not shutting off when the fuel in the bowls reaches the proper level. We know the petcock is bad because it has to be leaking with the bike off to get that much fuel in the oil, which it shouldn't because of the vacuum petcock. Easy way to test is to pull the fuel line and see if fuel comes out even with the bike off and the petcock OFF. Should be no fuel coming out EXCEPT for the PRIME position.

^^^ this. I experienced the same problem. Easy fix as long as you are a little mechanically inclined.
