Once all your leaks are fixed make sure you resynch the carbs and adjust the idle mixture screws

Yeah, that's what I ended up doing. They should be here next week ish, and I'll try to get some hard fuel-flow numbers.
In less quantifiable news - swapping the fuel filter for a nicer right angle one helped even more. At this point, the bike will run nicely up till about 35mph and then just lose power. Wide open throttle is still weirdly jerky but works in 1st and 2nd. It's also taking forever to warm up: I was riding this morning around town and it took easily 20 minutes to warm up completely. Granted, it's cold today, but not THAT cold!

i know the hose clamps are ugly... nicer ones are in the mail :/
Anyway, all of that is making me think jkv45 is right, and the bike is running lean from a fuel flow issue. My next step is gonna be to clean the petcock filter - just gotta get the solvents and stuff that the service manual recommends.
Will update when I do. It felt great to be back out again, even if just around town.
