What does that mean? Oil over filled? Engine filled with water?

Bike is a barn find. Have not gotten it started yet. Just curious.
Maybe you've never had an airhead engine cover off.....

The cover is just that, no connection into the crankcase, other than the breather passing through. The hole is there to shed water that could enter through the air intake opening on the top of the cover.

As ME 109 said, the starter and the flywheel opening live in there. Could be Rear Main Seal oil coming up.
