Plugs

[Timbox2]

changed the plugs on the Tigger the other day to iridiums,

2 of the 3 old plugs came out looking good, 1 not so, No 3 counting from the left,
 Heres a couple of pics, anything to worry about do you think??


The first 2 looked like  this



No3 Looked like this




Cheers for your thoughts.

That third plug also looks OK IMO.  If the bike is running fine I would not worry about it.  But if you want to make sure cylinder No 3 is not running a bit rich, or what ever, then get the bike looked at to see that the fuel mixtures and balance is all good.

Cheers!

Cheers mate, on thinking about this Im now wondering whether infact it is engine oil running down the threads, maybe one of the cambox plug seals is weeping a tiny bit, must be very small though Ive just done another oil change and nothing used since the last one

Actually, those plugs look great. I run iridiums on my Uly because of propensity to foul. Got 20K mi on current set and still very sparky.
