Not sure what to say.
Going to start with check your GROUNDS! Is the battery grounded good? Frame,engine, and wiring harness.
What voltage do you have GOING TO the ignition switch? Should have battery voltage.
Turns over fine with kill switch off..I have heard this before. But at the moment cannot think of what it is. Someone should chime in and jog my memory or say what it is.
Over charge would really only hurt the battery long term. But need to check regulator also. I have seen bikes get 18 volts on a trip and we fix the regulator and everything else works fine after(even bulbs).

Not to confuse anyone. Grounds do not make "more" voltage. But it can back feed circuits and "make" voltage where grounds should be. That is the only reason I said check grounds.
Yes timing could cause starting issues. It "sounds" like it isn't getting enough voltage or losing it. Keep in mind I can't hear or see the bike. I am just throwing things out to check.
Like I said. I have heard of this but nothing is ringing a bell at the moment.

Glad to hear you got it. Charging standards to me is 13.4 and up is good. BUT less than 15.
