Now that I have installed the T-Max and everything is running right I am wondering what the plug colour should be?? I know its harder to guage plug colour with unleaded fuel but I am just trying to get an idea.Before the T-Max they burnt white which the manual says is ok but didn't sit right with me. Now the outer rim is black and the centre electrode is tan which means it is running richer and cooler (great). Is the colour of my plugs about consistant with you other T-Max users and/or bikes running well in general. I have a plug chart but none of the pics really match what I just described.

Thanks guys,so the way I see it the plugs should be black around the outer ring and white to tan in the centre, is that consistant with the way your own plugs are burning??

Thanks again
