After I did counterbalance adjustment this morning I pulled all the plugs on STella to check their condition.
Noticed that the lead for the #3 cylinder lead was loose.
After I pulled that plug I shone a flashlight down into the combustion chamber and saw the top of the piston was black and damp even though the bike was at three bars of temp from running for the counterbalance adjustment.
The plugs looked good, nice and tan. (this is the #2)
I'm not sure as to the source of the oil on the plug body so welcome thoughts on that.
I haven't done a test ride yet so wondering if perhaps the #3 cylinder was firing intermittently.
If it was I suggest that would have a rather dramatic negative effect on fuel mileage.
