I am working on a buddy's 96 Tunderbird 900
The bike was badly neglected over the last 16 years -- it has 1.600 miles, and spent long periods -- years -- without any use.
I cleaned the carbs (and intalled new float needles and gaskets and o rings), and reinstalled them. Hooked them up to a remote, gravity feed tap/tank from my 75 Commando, as the T900 tank is badly rusted and I am not finished cleaning and sealing it.
Fired up pretty quickly and ran strong for about 5 minutes, then slowly died out and would not restart. I heard a gurgling sound from the airbox while it was running (which I had cleaned out when I reintalled the carbs.)
Is the vacuum line to the tap (which I did not block off) screwing up the fuel flow?
Duck bill was clear (at least, I could blow air through the fuel intake), at least when I fired her up.
Get it running on the remote, and then when it starts to idle down, turn the petcock off and hold the rpms up for 20 seconds or so with the throttle. If she idles clean with the petcock off, but the problem comes back when you turn the gas back on, it's the floats / float valves / o-rings (which you replaced, but I replaced mine a month ago and she's doing it again. If you used the GSXR rebuild kit, the o-rings are just a hair thick, which seems to cause problems in the short term.)
