i pulled my plugs after about 1 hour of run time and 1 plug looks just a little rich not bad at all but the other is completly black.
i have blue spark on both plugs and i run a 2 into 1 setup so iam not sure how one is richer then the other. when riding it the power band seems like when its not up to operating temp. when i forgot to turn the gas on i went thru the gears and it had a great powerband. so does anyone have any ideas?
