The ignition wires between your coils and the plug caps tend to "corrode" over time on their ends.
Take the plug caps of and cut down 1cm and rescrew them in (I like to put a tiny dab of battery grease on the cable before re-screwing).
I had the same issue on the coil side too....the cable was completely black from soot.
The connection between cable and coils/plug caps work like a "wood screw"...so pretty crude.
Youre regulator should protect your battery from overcharging, it can cook over if its charging too hard....be careful.
-->I had the same issue and found out that there was a malconnection in the loom to the regulator,check all the connectors to the regulator!
Try to cut the cables first and see what happens.
Did you clean your carbs?
One type of the XS carbs has a starting circuit which is "embedded" into the float chambers...there is a tiny orifice which when blocked can cause these issues!maybe you can unscrew one of your float chambers and upload a pic of the inside!
Good luck!!stay on it!!
