The gas tank vent may be stopped up. Easy test is to see if situation changes with the cap open. On the first generation bikes there is a fuel pump that may have quit too. Check for fuel flow to the carbs with power on. The pump should supply the carbs at 2-4 psi. If the bike has been sitting a lot both items are suspect. If the tank has fuel, it will migrate down to the carbs over time and fill the bowls, but won't be enough to stay running.

So, if you drop the fuel line off, turn the ignition on and the fuel pump doesn't run, don't think you have found the problem. To check the pump without the engine running you need to make up a wee jumper line as detailed in the Haynes manual.
