Okay, I've spent a week looking through everything on this site for something that fits my situation.
I have a 1980 Honda GL1100 Standard with full vetter dress that I have rebuilt from buckets (withimmense aid from this site). I was riding two weeks ago,at a stop signon a steep uphill incline, when I took off, I lost power, but was still running. I got it hobbled back home to find that I had no spark in the rear two cylinders.
Here's what I have done so far:
Wired as normal: Spark in the 1-2 cyl, no spark in 3-4, will start.
Swapped spark unit plugs: Spark in the 1-2 cyl, no spark in 3-4, will start.
Swapped coil power source (blue & yellow wires) No spark in 1-2 cyl, spark in 3-4, won't start and backfires (possibly because of unburned fuel)
Swapped both coil power source and spark unit plugs: same result as above.
I have changed out the left coil that didn't bench test reliably: Still no spark in 3-4.
From what I've gathered from this forum... the only thing left is the pulse generator... I think. If you have any other advice, I'm willing to look into it before going back out to pull the back wheel and swing arm.
And the other question... Where in hell do I get a pulse generator? New or Used?
Let the games begin!
