Just stick with the basics. You need air,fuel and spark. With these three it should at least try to start.
Maybe a rectifier/ regulator problem I think its a one piece box on these bikes.

right, so you saying the charge drops to 6volts once in a while and you wonder why the bike cuts out once in a while?
either there is a big voltage drain somewhere (usually reg/rectifier to earth) or the battery is knackered
This will be interesting when you find the problem.
You say: I've looked at the fuses, it is definitely an electrical problem
Then You say: Fiddled around with literally every connection
"fiddled" is good but have you TESTED, literally, every connection?
You say: no customizations OTHER THEN new handle bars.
Then you say: looked at the killswitch on the inside and saw the two little silver contacts and they seemed to be clean.
Also say: checked the killswitch again and all seemed to be perfectly fine, there wasn't much I could do to tell if it was bad, but it all seemed connected.
Have you TESTED?
You say: I've tightened the terminals, they do seem to be a little rusty but I'm not sure if that's vital
Wouldn't that be considered an electrical problem?
You say: Checked the ignition coils for any problems as best as I could
Tested??? (btw, no, the coils aren't aircooled)
You say: I know this isn't a fuel or air or combustion problem.
Maybe, since you mentioned shuts off suddenly - if that is the case.
Did you have this problem before your only customization (handlebars) and if not did it begin shortly after that?
Someone mentioned wires from ignition and possible damage.
Rectifier probably best thing to TEST; easy since you have a multimeter.
You say that it's getting worse. Do you mean more frequent or shuts off faster.
I like the suggestion of shaking the tank due to debri, keeping it simple.
Is there water in the gas?
If it's electrical is the battery grounded?? Again keeping it simple.
I'm a newbie so not trying to be "smart" and really don't think you should just give up!! I think someone also mentioned getting a service manual - those are helpful. But don't give up.
I wouldn't reply to this with my limited mechanical ability but since i had a lawnmower with almost identical problem (hey, at least it's a 4-cycle combustion engine, ha) .. . .sporadic, would quit, then run awhile etc. (the exception is there was slight bogging when it quit but not much). Turns out it was suffocating for air and just needed an air filter.
Start simple, try to recall taking the handlebars off maybe. Also don't wear down a perfectly new battery the same way as last (not to mention the starter!) (at least the start button works darn fine
)
