I'll pull the plugs in the morning to see what's going on.
The thing that puzzles me is the oil at the exhaust end is black, the oil in the crank case is gold. The bike isn't smoking so it would lead me to believe that if it's a valve guide seal it must be the exhaust valve, and it's not being ignited.
So...I'm wondering if the oil that the PO put in was automotive oil and a thinner viscosity, then if the seals are weak the oil would seep.
Still the bike is running strong!
