Well I was undoing the bolts on the left crank case, to remove it and tried taking a rubber mallet to get it off, haven't got it off yet, but i noticed clear liquid leaking from somewhere. Is this normal? I don't know why it would be leaking if not.

 

Seems like it quit. If not it isn't as leaking as much. Was this due to built up pressure inside the casing?

 

Now it looks like normal oil. Its coming out from the seam of the left casing, and from the drain plug. Could this be normal oil left over from draining it?
