More likely the inner primary seal is leaking . The oil runs down the back side of the inner primary and finds the lowest point to drip from . When the bike is on the jiffy stand the lowest point would be at the drain screw . Use a mirror and flashlight to look at the back of the inner primary to locate the leak . The fix is to remove everything and replace the seal .
