Is this running too hot or what? It's got about 40 miles on the plugs, this is what they look like the next morning after a 25 mile hill-climbing excursion. Power output is what I would expect from a 92 Polaris 500 efi. Oil brand is unknown (still on previous owner's oil) but the oiler is set rich. This is definitely the lightest color spark plug I've ever pulled out of a sled but normally I intentionally jet on the rich side so I don't know what "correct" really looks like. These are BR9ES. Any comments from the more experienced tuners? Should I be concerned?
