My battery was completely dead after letting the bike a few months. The bike had been running progressive worse before I parked it, and It was a fairly new gel battery, so I suspected either a bad battery or a charging problem. To get to the battery, I have to remove both the seat and tank, which is a minor pain. The battery took a charge and held it well for a couple weeks. I took the 53 year old selenium rectifier out and tested it, and the resistance in the flow direction was extremely high. I ordered a combination rectifier/regulator from Sparck Moto in hopes that the rectifier and/or the regulator were faulty. I modified the regulator bracket on the bottom of the battery box to fit the new part, and put everything back together. Took a test ride today and the bike ran well, with just a slight miss on the left cylinder around 8000 rpm. I'm guessing the points probably need some attention.
