Hey Yoshi, I had a leak where the stator wires exit the engine case because the rubber grommet was gone. It would leak a little when parked after a ride.
I had to clean the wires and the opening with alcohol and then seal with RTV.
Used a mirror to make sure I got the RTV all around the opening and wires.
Hasn't leaked since. Next time you have engine running check oil window and see if it's still black, if not, you might have a tad bit too much oil in it which would make it all one color when engine is off. If it's truly black I would think the oil needs changed. Good luck with the leak.
All fluids changed
