As some of you may also recall, I recently broke down twice on the highway, right at three hours into the ride. I believed that I had a faulty ignition coil that would cut out once it got hot. Once the bike cooled for an hour, it fired up and ran great, both times.
Fast forward to yesterday, it broke down about two and a half hours into the ride. It was running but missing badly. I assumed it was the mysterious heat-related issue again. So I stopped, waited, and no change. This morning, no change. I tore the carbs apart once more, found nothing, sprayed out every single passage again and confirmed there were no blockages, reassembled, and still missing like crazy.
The points are opening and closing. I measured the primary coil resistance on both coils to be good. I tried to measure the secondary coil resistance and wasn't able to get a reading on either coil.
I replaced the plugs.
This thing is missing bad. I've put about 800 miles on it in the last 9 days, and I have about 400 left to go. The change in running was brought on suddenly, which lead me to believe it was a carb issue. But the fact that I had an inline filter, found nothing, and all the passages were spraying clear suggests otherwise.
I want to check compression next. Compression was great three months ago. Brace yourselves: I never checked the valves. I might have burned one.
Throw yourselves at me. Err, your knowledge anyway.
