oohh man, u got me there, care to elaborate?
or tell me how mine looks ...what am i looking for?

Burn rate at 3 and 9 o'clock on the base of plug.

here is the plug in my bike now ,that other on is junk, what am i looking for for heat?lol

This was an early run just after switching to alcohol. A single 1/8 mile wide open asphalt run. Shows very little heat. Just burned off the plating next to the ground strap. Wet and safe but to cold. From there we started closing down the power jet.

That is a great pic Tedder, that is were I like to see it start at. you can see the discoloring perfect at the base of the strap. the more heat it makes the further around it will go. half way around at 9:00 and 3:00 is good heat

have you purged on those plugs??

i see
how close is safe

yes i did..

That plug was pulled at the end of the run. It hadn't been used to purge - Is that what you ment??

it is hard for me to tell on purged plugs but I think I can see the burn marks and they look pretty good. I always start with a fresh set of plugs and tune for that day


tedder I was asking airbrusman because that plug look like it was purged with
