Started looking for an oil leak that developed recently. Pulled the upper fairings and tanks, degreased the front cylinder. I'll put the thing back together tomorrow, probably ride it Tuesday, then check and see if I can identify where the leak is. Could be the valve cover gasket (didn't change it at last valve adjust), but I suppose it could be one of the spark plug shaft O-rings or one of the seals on the valve cover bolts.
Looks like there's the beginnings of a small leak on the rear cylinder too, definitely from the gasket.
Maybe I'll wash it after I find and fix the oil leak.
