There are 2 kinds of stock regulators. Pre and post 1980 use different regulators and they are not interchangeable.

its stock with brushesstock with brushes.
Aftermarket PMA
Pamco is the ignition system, not the charging system.
So when you measured high battery voltage how long had the bike been running? Had you ridden it or had it just idled for a few minutes? Without the load of the headlight you could have sent a bunch of voltage to the battery real quick before the regulator had a chance to shut off with only a load from the tail light and coil. I would unhook the headlight and let it run with my meter hooked up, watch the voltage at the battery over the course of a few minutes. See if it jumps up to 18VDC then slowly starts dropping or just stays there. if it slowly starts dropping to 13-14 then starts modulating you're fine. If it jumps to 18VDC and stays there you have a bad regulator.
If you are running a PAMCO do not let it get over 16 Volts to the coil or you will shortly have a new ignition system in you future.
15+ at the battery and it's future will be short also.

Show us a pic of your brushes and the part number of the regulator. My feeling is you have the wrong regulator causing the alt to be always full charge, you can easily loose both your pamco AND the rotor if you don't get this sorted quickly.
