So I decided to repair the diaphragm and it appears to have work. I reassembled the carbs and put them on. It sounded better but it was still not really running. After fiddling for what feels like forever I decided to swap out the vacuum line on the petcock with the one that goes to the cruise compensator. After swapping those out the bike almost runs like new. I think the whole time the vacuum line just wasn't supplying the carb with fuel, but my guess is that now the compensator isn't doing anything. Why would one vacuum line not be working? I'm not trying to tune the idle right and when I blip the throttle the revs sort of hang, I think there must still be some underlying issue, any thoughts?
