Man, people ask alot of questions of what to check!!
To me, gas in the oil means 1 thing. when the bike is stopped, gas is leakng from the tank into the carbs, and follow the path of least resistance into the engine.
this happens frequently on older bikes where the owner forgets to close the fuel petcock and the engine fills up with gas.
I actually hate the modern automatic fuel valves because you dont know if they are always working. i like having control of closing the petcock manually.
I would try pulling the fuel like from the carb and see if gas is comming out of the tank. ideally gas should only come out when the vacuum of the engine is running.
just a cheap check to make??
