Bonneville America Forums Forums Technical Forums General Tech Backfires

Jim you may have hit the nail on the head. Mechanic at the dealer mentioned the same thing i.e. the troubles seemed to start after all the work to fix the bike after the accident. The last time I had it in they supposedly checked all the electrical connections and greased all of them. Also, they tested the ignitor and coils and said they checked out fine (i.e. they didn't know what was causing the stalling). Also, checked and re-balanced the carbs and checked the air vent hose. It was backfiring then too but not nearly as bad as this time around. Yes the coil wires had plenty of grease on them as well and they were on pretty solid. Since the problem seems very intermitent mechanic thought that it was probably a loose ground or connection somewhere (that they may have missed when doing the accident repairs). He said they were going to tear the entire bike apart (down to the frame if necessary) and put it back together from scratch. We'll see what happens. I'll keep everybody posted...
