My 91 900ss seems to be leaking oil from the clutch rod where it goes in to the engine case I removed the clutch slave to find the leak I looked at my factory ducati fintch but did not see a seal could it be the engine is over full with oil I checked the oil level after a ride and it looks maybe a hair over full I usually run the level in middle of max/min when hot don't know if that's correct or not any advice
