my 72 bonneville always wants to die on me at idle and i often have to rev the engine to keep it from stalling. actually it did die on me yesterday at a stop light after couple blocks from a cold start and i couldnt start it no matter what i do. then i found out that the battery didnt have a charge to get a spark.i recharge the battery and the bike lives again. i check the bike over with a volt meter today and i only get 11.23V @ 1000 RPM and barley hitting 12V @ 2500 rpm. isnt that kinda low? the bike has electronic ignition . 6V coils and NGK plugs.
