| |This seemingly case seam leak turned out to be a leak at the point where the stator wire grommet comes through the primary case. The oil would pool up on top \\ of the transmission during riding and when parked would run down the back and onto the ground. Every morning, after riding, there would be a 6" oil pool under \\ the bike. These pics are underneath from the rear at the transmission.
