Thanks Tom for the info, you have been a big help. The bike started missing once when I was riding it, but pushed thru it an kept running. How many grounds are there? To bypass the side stand you just solder the two wire together ? Thanks again Dan
Egad, I'm not sure. There's a ground coming off the battery, one coming off the starter, a frame ground lead that is on the upper coil mount bolt, an engine ground lead...
Pull the tank off so you can see a lot of stuff. Start looking for wiring harness terminals. Loosen and then tighten every one that you can see, especially the ones associated with the coil. Grounds, positives, it don't matter. If it looks electrical, tighten and loosen it.
Oh, and this may be silly, but remove and firmly replace the coil lead to the spark plug - make sure that sucker is really clipped in.
Fixing intermittent problems is a real PITA, so you have to use the shotgun approach. Down side is that once you've fixed it you may not know what was wrong
And yes, the side stand bypass is done by shorting the two main harness wires together.
Hope you get it solved!
