Well, doggoneit, I sure wrote a less than clear message. I replaced the plugs and wires last year, not the coils. And yes, I was chasing the slight miss and since the wires were original (210, 000 ish miles), I went that route. I used a pretty primative spak tester that throws the spark across an adjustible gap and concluded cylinders 3 and 5 were weaker than the others.
I now own a good non contact thermometer and will measure the temp on the exhaust headers to see if I can pick out a weak cylinder. It's nothing that keeps me from riding. I like tinkering.
Bad choices make great stories
