well I think I have finally found the leak. I smothereed the bike in talc and went for a ride. If I ride up to 40 then there is no leak, continous riding at 50+ gets the Torre Canyon treatment on the back wheel.
After faffing replacing every seal I can think of, it's coming from the stater area.
As I have put my ignition switch opp the starter motor, the oil at the bottom gets flung up, I put a baffle there to prevent most of it travelling, but for some reason, its throwing more up. this then gets into the hollow where the starter is and drains through the drain hole right where the chain it etc and then it sprays everywhere.
Ordered a core plug the same size as the hole and I'll grommet it for the ignition wires and that should be that!
I've ringed the drain
