Got what appears to be an oil leak after riding on the left rear corner of the oil sump behing the side stand mount. I'm guessing the sump gasket has started leaking under oil pressure in use. Why the sum gasket should develop a leak having not been touched is beyond me. The pic show the back left corner of the sum looking up at the side stand mount. Oil filler pic shows the same sump corner from above show no oil leak. To get a clear view i'd have to take off the side stand. It seems the oil is spurting out at the sump corner gasket. I guess I'll buy a sump gasket and chahge it the next oil change. Is this a simple? Drain the oil unbolt the sump. Replace gasket and refit?
