    Default A little plug reading help please...

    Hopefully my computer is pic friendly tonight.... Here are 2 plugs with about 5 hours on them. The one with the ground strap that is the lightest...is #7 the other is # 3. I guess my question is ...is the ground strap supposed to be white past the bend? Isn't that a heat range thing? FWIW These are ngk r5671a-8 plugs. On the air fuel gauge... with these headers I am at 12.5 to 1....is that about right?

    It was REALLY pig rich with the tt's....those pulgs are with my dry set. I just slapped on a set of ot bassets....thought I would take a peek at a couple of plugs. Is 12.5 to 1 @ wot about right? (assuming my gauge is accurate).

    No blower here...I guess I will drop a couple of jets. I'm adding water injection...just bolted some ot bassetts on. Will that likely affect jetting? I know with my tt's the plugs were black...so I'm guessing the answer to that is yes.
