i had a vstar 1100 that had an ignition coil crack open, mine were under the tank, i was running hard and hit a freak cold rain storm and the cold water sprayed up and hit the hot coil, and it cracked, any moisture, any at all would cause all kinds of hell. i found which one was bad by pulling the plugs and looking for the one that was fuel fouled, traced the plug wire up and removed the coil, i put it under a heatlamp for a few hours and checked to see where the moisture was coming out, then sealed it up with epoxy after it was dried out, mine was banging out at speed, acceleration was erratic, all kind of fun stuff on the highway. but, this sounds more like a fuel/vacumn issue, does yours have the siamesed kehin carbs? that sit in a "y" manifold that feeds the cylinders?
