I have known the crankcases to fill up with fuel that has leaked past the float valves and run into the engine.
You should always switch the fuel tap to off position when storing the bike.
The easiest way to check for fuel in crankcases is to remove the carbs and reed valve block and look inside?
The carb's may need a complete overhaul and possibly the fuel tap is leaking past in the closed position.

That happened to me, couldn't start the bike because it was hydrolocked!! Turned out to be the float heights were slightly out. Also worth noting that the overflow pipes can be fragile in the float bowls, so take care whilst cleaning around them or you'll snap one off like I did!
