Gas in the oil is usually an indication of a faulty petcock on the fuel tank. Gas is being supplied with the engine off and getting past the float needles in the carb(s). Over time, sufficient gas can fill a combustion chamber,too. Be wary of trying to satrt the engine without removing the spark plugs and spinning it over 1st. Rememdey for all of this is rebuild or replace the petcock and then replace the engine oil. Run the bike for a half an hour and then change the oil again. have fun!
