hello everyone, need some guidance on my newly acquired 1977 cb750 that has a charging problem. Short story, it is not creating enough voltage. Here are the facts

stator looks pretty new and in good condition
battery is most likely only a year old
dyna ignition
Ricks reg/rectifier

key off, battery 12.2v
key on, battery 11.3v
bike on idle, 10.9v
bike on 3k rpm, slowly rises to 12.5v

the lights also get brighter when revving (indicates some sort of increase in voltage)

I did search the forum, and will do all the tests I've read about as soon as I have some free time, but I thought I would ask on here in case someone has had a similar problem. Any input would be great. Thanks everyone!
