Hi again folks! I've just been confronted with another perplexing issue. The bike (74 850, PowerArc ignition) has been running great, but the other day I went for a ride and it started sputtering, cutting out and backfiring. I then discovered that it was only happening when the ignition switch is all the way over in the "lights on" position. It runs fine when clicked one position over, with the lights off. I just checked the wiring in the master switch, and everything was tight. I'm going to try to trace the problem, but thought I'd run it by the forum first, in case it's an obvious fix.
