Yep that's the case here.

Then carbs with non-sealing float-valves just drip that petrol down intake-tracts into cylinders. Which then drips past rings over time and into crank case.
Ah ok. Then just depends on how long this's been the case.

This happened on my 2009 Ninja 250 and caused stripping of starter ring-gear. Also happened to '85 VF500 parts-bike I got dirt cheap because engine was "seized". When I opened oil-filler cap, over gallon of oil+petrol mixture gushed out! Fixed petcock and carbs on that bike, which ran perfectly fine afterwards. Ended up giving that one to my brother.
Well that's some good news, relatively. Guess it's probably not that severe then, awesome.
