the cap was barely hanging onto the spark plug wire! seemed pretty corroded in there, too. this was the inner on the left side.

so uh... check your caps and wires once in a while, I guess that's the lesson here :D

also Todd please sell me a new set of plug wires and caps. (yes I will be emailing shortly)

Yep, that will do it! Seems there are several recent posts about spark plug wire issues again…Obviously..it’s the beginning of the riding season and the same issues rear their head every year like clockwork! 😆

I think you could do it just removing the tank, but I removed the whole intake too

I don't even remove the tank. I just loosen everything and shift the tank from side to side depending on what I have to access. When you remove the inner spark plug, blow compressed air in the area to remove any debris, then use a thin wall socket to extract the spark plug. Well covered on this forum.

You know, they have said for a few decades now, that the modern coatings used on the plugs no longer requires anti-seize compound anymore but I still always take a Q-tip and wipe just a very light dab onto every plug I seat. Always have. I think it is cheap and practical insurance against what can be, a disastrous event.

Then again, I am a lover of modern chemistry in vehicle maintenance and repair. No snake oils mind you, but proven chemicals that actually do the job they are designed to do.

So i got the inner plugs changed. Somehow also had the foresight to have complete plug wires on hand. But the coil?(the electrical box the opposite end from the spark plug goes) is green and corroded. How do you clean that?

Electrical contact cleaner. Available at most auto parts stores. If very heavy corrosion, start with rubbing alcohol and a q tip. Then use the contact cleaner as it will help prevent future corrosion.
