Ah, that's interesting BluprintZ... the same cause as in Red98's stuttering thread. Though, if it upset the battery too it may have been been a simple failure of regulation allowing the volts to get too high for the ignition to cope.
Torque: a basic check of the reg/rect just needs a voltmeter to check the battery volts rise from 12.7 (ish) when the bike's stood overnight to 14.5 (ish) by 5000 rpm with the headlights on and doesn't rise beyond that at higher revs. That indicates a healthy battery, charging and regulation.
IIRC Red98's regulator seemed ok on that check and my guess is that it had gone into some weird oscillating mode, the simplest check for that is to swap it.
