This is what I found. The exterior nut base of the plug was rusty and the electrode area was charcoal grey. I know this bike runs rich. If I ever get motivated to r/r the carb, I'm going to raise the jet needle one position up from where it is now.
The main reason I changed the plug is it took me about an hour to start the frickin' machine when I went riding yesterday. I've never experienced this (maddening) problem before . I was burned out and I hadn't even ridden 2 feet yet.
Anyway, I changed the plug, gapped it to .032, and the beast fired on the 2nd kick like it supposed to. Runs smoother, too. I'm going to monitor the plug color and if it continues (which it probably will) I'm going to adjust and rejet the carb.
