Hmm, ok, so most likely clogged carbs, with petcock not far behind. Best to do full restoration on both.
Got the vacuum gages in today - connecting it to the carb vacuum line while cranking makes it spin around like crazy. If I had to guess, I'd say the midpoint of the fluctuations was about 400-500mmHg, but I can't see that being particularly useful. I drained the fuel tank too, and the fuel flow looked like plenty and plenty steady to my (admittedly untrained) eye,

I would like to do the petcock cleaning myself, just to learn some more about the bike and have fun learning to wrench, but I don't think I have the free time to go about learning to do a carb rebuild on my own. Do you guys have suggestions as to a rebuilder I could send it to?
As always, thank you for your time & patience
