I'll bet your rotor is bad. Check the ohms, should be 5ohms??
It will run without the alternator connected and a fully charged battery.

Its an alternator, not a generator. Generator produce DC voltage. No rectifiers needed. Our beloved XSs have an alternator that produces AC voltage, thus needing the rectifier to change the AC to DC then regulated to 14.5VDC.

Get your meter out electric is like water it follows the easiest path
My '60 BMW had a generator. '69 and earlier Harley Davidsons had generators. Lots of pre '70 British bikes had em. You get the idea. When you have to "flash" your new armature after installing to polarize it, you have a generator.
Fuse blocks are notorious ignition switches go to hell start at the battery and work your way towards the coils. Get a simple tester and electrical diagram.
Set camchain set valves. Now for a carb overhaul. No way around it! Read the carb guide 3 times before you even start.... Seriously. Do it.

See above. Duh....
Also check the advance mechanism. It can cause backfiring if it's sticky. Use the search function for threads on how to check it.
I am guessing you have already: cleaned and set the points.
Checked timing, did the electrical trouble shooting.
Dumped the old crap out of the gas tank, cleaned it
replaced the fuel lines
ordered the parts for the carb overhaul?
