http://forums.everything2stroke.com/...f?d=1147400070 < plug diagram. as long as you stay more toward red/blueish you'll be fine.. go the other way and you'll start to run into problems. just to give ya a reference point

what's the main jet (size)
what's the pilot jet (number on side)
how many turns is your air screw out?
what oil do you run
what octane gas
and at what ratio is it mixed at?

Man that's new material to me! I'm not sure I understand it though. I've never seen green, red and blue on my plugs before. Are the colors on the insulation itself?

but black?

maybe rings are going?

Black plugs are black because there is excess fuel not being burned. It doesn't have to be wet. That indicates that it's totally flooded. Lean it out and it will turn tan.

nah that's just reference points i drew in... it'll actually be a darker kinda burn pattern on the side.. if ya look you can see it.. and it's way more acurate on telling bike condition (rich/lean)
