Honestly, I've never chopped up a spark plug to check the base of the electrode for coloring. At this point im pretty familiar with what the bikes I work on should run like, and how to correct said issues.

Like right now I can tell that after adjusting my derbis timing 2* advance, I need a bigger cutaway in the slide and to raise the needle, due to a cold temp lean bog at 1/8-1/4, and hot running conditions mid throttle.

I do agree Mark, vespas, specifically kitted bikes, will have a lean side on the exhaust side of the plug. I try to tune that out if the power can head a size or two richer
