there both rich. dirty air cleaner.
good catchYou're looking at the electrode, Hog? That's a precious metal plug. Iridium or platinum or something like that. They have those weird little electrodes that look like they're a normal plug that's been worn away and is trashed.
I was trying to determine if I was seeing a little bit of pink color on the center insulator of the rear spark plug. If that is pink I'm seeing that might (or could) indicate too low of octane, or maybe 20 other things...the tips look clean i wonder if to high octane fuel would darken them like that....or the mixture screws are out to far
Yes I was looking at the electrode Eye. You are probably right then since you see modern plugs way more than I. It sure looked shot to me. As TR indicates, it still might be his problem. You don't go throwing these modern plugs in anything willy-nilly. If that's what is recommended and is the correct plug for his machine then would that also mean it's fuel injected which might mean his mapping is off? If not then I think I'd go back to antique plugs just to get a good reading. Maybe y'all can read plugs that have been in a bike a long time but I can't unless it's very obvious. Like a dripping wet plug or very oily. I need new plugs and I guess these modern plugs are too expensive to have extras for just this purpose.You're looking at the electrode, Hog?
