I have a '20 R1250RT with about 15000km on the clock.
Discovered couple of weeks ago a small oil stain on the right valve cover, probably a leaking valve cover gasket, but it's very difficult to see where the oil comes from because due to the wind the oil doesn't stay at one place. Cleaned a couple of times the valve cover but it comes back.
Loosened the 3 valve cover bolts and tightened it al 10Nm as prescribed, but no result.
Before I'll go to the dealer I'm wondering if anyone has the same experience maybe?
