Spark plug question
Bought the bike, replaced the plugs, ran a little over 3000 miles and reached the 15k service so I pulled them to find this. Is this normal?
Am I running rich? For sure smells like it. Where should I begin?
I replaced them today and road around for an hour. It’s always ran great and never had any major problems, just basic maintenance and slow warm up time, you’d expect from a 30 year old bike
But i would say it runs pretty hot, I’ve been reading about switching the coil/ignition module to single fire instead of dual, would that help clean these plugs up any?
Thanks for any help

IF…( that’s an important if..) you pulled them correctly, they’re definitely reflecting a somewhat rich condition.
Easiest ( read: least costly) mod to try is another set of plugs that are a bit hotter.
Whatever you do, don’t make the mistake of lugging the bike around, through the neighborhood for example, then pulling the plugs to read them.
