any instruction on how to proceed once I have it exposed? anything to look for?
Yes, a test light at the ready.

1. I want to run a test light on each wire, not the coil's threaded stud.
a. What wire off the stud is loose or about to break off I have a visual.
b. So my wire integrity is fine, I now want to touch it key off and see if the stud bolt(s) is loose?
c. I want to have that test light on a wire before the eyelet so I can push/pull on that wire, see if the light goes offandango I now have the key on >> After my visual and touchy-feely.

2. I want to start the bike, move the wires as a bunch that is off of the coil stud.
a. I want to touch wire not grab the exposed metal eyelets or the coil finds me as the shortest path.
b. I find the bike idles fine with all this tugging of some sort of wire internally that may be frayed inside?
c. I find no joy at both static with the test light, now I start the bike and could have tried it this way first?

3. I have a computer bike. Why, I'm chasing my ass this way first. Why am I not at my first move and now my second move?
a. I have an electronic wizzbang that needs 5v and I mean 5.0v, not 4.9v.
b. I checked the battery first. No, I thought you did? No, I was checking compression to eliminate the 3amigos and leave all doubt about that one.
c. I thought you had the volt meter at the battery? No, I was at the taillight looking to start someplace but here is where I stop. Yeah, but who's going to check if the 12.6v static is I better call VoltbusTTears or the truth tables says junk in and low amps out I matched input.

:D

Signed,

Only your battery knows for sure go chase your computer tail if it's not compression, right? Starts right up? Ah, not compression. Computer bike? Ah, needs 5v.

:hi:

New spark plug wires. Use a noise filter on the primary side of the coil, preferably a ... shit, what's the name of that filter part?

If you don't agree with what I posted then explain why you can't post something positive?

Same advice.....

Maybe I missed it somewhere, but is it carburated or fuel injected? Kinda makes a difference on troubleshooting.....

Nope you didn't miss it...the question was asked multiple times but no answer was never given.

Post #4, 5 and 31.

Good luck with the fix.
