I still don't really understand how, but yes, a weak battery WILL affect the ignition system on a Vulcan 750. You would think the stator would be putting out enough power even at idle to power the ignition system, but apparently not. Having 4 plugs to fire may have something to do with it. I have had this problem after jump starting my bike with a nearly dead battery. It would rev fine, but would not idle. My '85 Goldwing seems to have a similar issue, but it also has fuel injection. It's an old analog system, and draws a lot of current. OTOH, my Honda Rebel and Yamaha XT225 will idle just fine with a dead battery.
I am a motorcyclist, NOT a biker.
