I would run a cooler plug like a P4 or OD 97T...was the plugs wire distorted and a bit pushed in?

I to have had that richening up during fueling, its been a long running debate to wether its tuning or a mugen tank thing.
It seem strange how a plug can be working then dead the next time you go to run but its simply broken the wire during the run but stayed glowing until you shut it down or it flames out.

i'm running my GXII un modded but i'd like to see what the muran mod looks like if you ever strip it please post some pics...Hey great job on the win though.
