Help reading plugs

[Triple Trouble]

Nowadays with unleaded gas it is a whole new ballgame too. Plugs don't colour the same. If it is clean and dry with a grey to tan colour it is okay. As long as there are no signs of "boiling" around the ceramic seal indicating extreme heat I wouldn't worry. I personally use antiseize and a torque wrench on my bike plugs just cos of peace of mind
