On my 763 I had a pump leaking at the seal which required the motor to come out. We removed the motor replaced the seal and all seemed fine. After using the machine for a few hours and leaving it outside in the rain I found I had an oil leak by the cover for the chain case/fuel plugs. Previously I had spot welded the plate in place as the holes were stripped. It isn't impossible to get off just a pain. It appears that it might be residual oil under the fuel tank. What I don't know is how much oil it might hold as I never had a tank out before and it has leaked a fair amount so far. The oil only really appears after a heavy rain so I don't think it is the chain case plug or it would leak all the time. The colour is slightly dirty but not black. I have cleaned all around the tank, lines and hoses and all appears dry. If it is not residual oil than I guess it must be leaking from the chain case somewhere? The rear top chain case cover is is tight and not leaking and all appears dry. I wonder if there is a vent somewhere between the tank and chain case? Any ideas welcome.
