Which is the less risky option regarding potential damage, running a hotter plug BP5, or dropping the needle a notch.
Rear cyl' seems to be running a little rich by plug appearance so I have gone to a NGK BP6 hoping the hotter plug would have better appearance but not much change with sooty appearance.
No problems with acceleration and fuel consumption is not alarming but I do get twitched about plugs fouling.
