It is definitely possible to overfill so that oil comes out of the airbox. You would see oil at the back of the cylinder.
If it comes from the rev-counter drive it can be the O-ring.
Or maybe the cylinder head cover was not properly sealed. I had the same. Was very hard to see where the oil came from.
