QUESTION: the drip when i see it is from the bottom of the primary at the drain plug area but this is not where it originates,,,,,i do not know where it originates,,,i cannot follow any path because unless u ride it it does not leak at all and after u ride it and try to find a path its impossible due to wind just scatters it,all areas on top and sides  of motor are clean and dry right down to bottom.

Answer
From that area there are three possible places that you can have a leak. Main seal for the tranny, mainshaft seal, the seal between high gear and the mainshaft and the inner primary seal where the tranny goes through the inner primary.
Good luck and happy riding
