Tried every which way to get it started. So far, I've rebuilt the carb, replaced the battery, spark plugs, oil. The coils seem to have tested ok. Still no spark on either of the two plugs. All other lights function.
All fuses are ok.
I wasn't sure if the regulator going out would cause something like this. Everything on the bike works but still no spark. The strange thing is the way that it happened. Suddenly, with no warning signs or intermittent problems. I'm about to lose my mind.
