    Id say it looks pretty good, fuel wise.
    Black ring = rich on the bottom end. Tan electrode = good mix up top. But the ground strap is tan all the way, you want the color on the strap to change right around the the middle/bend
    Start tweaking the timing.
    What bike is this in? And what have you done to it?

    Looks good to me too. A tan insulator (white part around the center electrode) is the desired condition.

    If the bikes running great, I don't see any cause for concern.
