"Red" sparkplug tips?

[Guest]

was working on a friend's 1100g (stock configuration)
all the sparkplugs have a light red-ish tan on the white porcelain electrode surround
no, not brown, but orangy/red-ish shade
plugs otherwise look ok

what could this be from / what would it indicate?

thanks guys

Maybe from some type of fuel additive

Your friend's bike has been staying out too late, not getting sufficient sleep and consuming too much alcohol. Tell it to straighten up and behave itself.

Check the tank for rust. Also unscrew a carb bowl drain bolt and see what comes out of the drain. I would guess there is some ultra fine rust particles from the tank getting into the carbs. Happened to me

His friends bike sleeps 23/5 & 21/2, can't consume enough liquor in the time available to be considered sufficient to harm, and says to tell you that your bike tires are overinflated, flat in the middle and that you should get your knee down
