My bike started running really poorly and i smell something burned. Pulled over to see the #4 spark plug cap about half way out of its hole. I clicked it back in and everything went back to normal but it keeps popping off.
I saw another thread with the same problem where tightening the plug fixed it for that user. In my case my plug was already tight in its place.
pulled the plug out to look inside, whats this black stuff in there? is this normal? and is it possibly related?
