Question about 1984 Honda VF 1100 Sabre
Yes, I suggest that you are not charging properly. the headlight to high beam killing in one instance and no effect later is the big clue. You were riding along, slowly loosing state of charge, and it was not apparent, then place heavier load, and the system does not have the voltage to run everything....so the rough, etc.
So, where are you? You need to independantly slow charge the battery. check water, and connection quality. this charge, on a home charger needs to be like 2 days or so...if it boils, get another battery or be mislead in other tests. batterys that boil do not make it, ultimately, and leave you stranded.
Then put the battery back in the bike, hook everything up, start up and at 1500 to 2000, measure voltage at the battery. Needs to be 13.8 to 14.2 or pretty close to that.
Bikes tend to overcharge batterys. This boils out the water, and cells goe dry and that kills battery, just replace it.
A common issue with bikes is the DIODE PACK, to make an alternator work DC on 12 volt systems, diodes are required. They are one way valves for electricity, and fail often. Then you have a leak to ground and the battery goes dead, as well you do not charge correctly, same leak.
Easy to change, measured with a scope, (yeah sure) or ohm meter. Continuity test, go one way no go the other. Any open, or connect in both measurements is failed.
My bet, diodes...And get a Harley. Just kidding, but you do get to know all of this stuff with a Harley, cause they always break...

Turn the engine off, open the hood, and disconnect the negative battery cable (--) with your pliers.
Locate the power distribution box against the firewall on the driver's side of the engine compartment. Flip up the latch and remove the plastic cover.
Determine which headlight fuse you want to replace. The 2001 Ford Focus uses four headlight fuses--one for each headlight. Fuse number 16 is for the passenger side low beam; fuse number 17 is for the driver's side low beam. Fuse number 26 is for the passenger side high beam; fuse number 27 is for the driver's side high beam.
Grasp the fuse with your fingers and pull it straight out of its mount. Insert the new fuse in its place. Replace the plastic cover and reconnect the negative battery cable.
