The bike has symptoms of a clogged inlet valve from junk coming from the petcock or a clogged pilot circuit. In short, it isn't getting enough gas to even idle.
The clogged cap vent is also a good idea, but that usually results in a bike that will idle fine and will run at part throttle well but acts like it is running out of gas at speed. That one is easily diagnosed by running with the cap open. It should run fine at idle though, and yours isn't.
Were it mine, I'd pull the fuel line and, applying vacuum to the vacuum line, dump a pint of fuel into a jar. Look for little black pieces of crap.
Pull the carb and remove the float and valve and look for blockage at the inlet, then pull the pilot jet and look for blockage in it. You should be able to see light from end to end, though the passageway is only about .015" in diameter. It's a wee hole...
Check the entire pilot circuit, making sure that fluid will pass from the pilot jet area to the three holes in the intake side of the carb venturi. WD40 can be sprayed through the circuit, though anything you have to spray through there will work.
