    Getting ready for a ride tomorrow and I decided to use my new Honda plug socket wrench and check the plugs. Both side plugs show an odd colouration which I have never seen before.

    One side of the centre electrode is a chocolate colour the other is white with no burnt on deposit. I am not worried about it but wondered why this happened. All I can think is it's the 3 valve head causing an odd swirl pattern.
