Hey all - just figured I'd post a brief update, it's been a while.
I've made some progress! Finding time to work on the bike with the wildfires and everything has been kinda tricky, but i made it out there yesterday and today. Some highlights:
I got the right diameter vacuum hose for the petcock, and that helped. I think the old hose was leaking or something; the last owner confirmed it's been an issue for him in the past. Anyway, that helped a lot (if not quite enough for me to be comfortable with it on public roads).
@.Danno, I tried to get a vacuum gage a couple times this week, but neither of the auto parts stores I frequent had them as loaners. I went ahead and just ordered one online, itll be here soon. In the meantime, I noticed that, while both are jerky and stuttery above like 6k, switching the petcock to reserve actually makes a difference in power. I think I'm gonna drain the tank and clean the petcock filter this weekend.
Here's a pic from Boulder this week - really spooky:

Anyway, thanks for all your help so far! Couldn't have gotten this far without you.
blessings!
