    wont spill gas, it has air flow but wont just give gas. i blow air through the top hole (i suck at terminology) and gas comes out, but when i stop the air flow it won't give anymore, not even if i shake it. i have no clue whats going on and need some help asap.

    its my transportation and i need it out on the road

    If the fuel level is below the petcock it will be reluctant to just flow oot on gen 2, I am guessing gen 1 has similar internal plumbing.

    There is a screen inside the tank on the petcock tube. It might be getting plugged. You have to take the sending unit out to get inside. I have a spare (crashed) tank. I'll double check today to see if there's any problem getting to the screen.

    Mea culpa! I went out to look and can't find the tank. I may have pitched it a couple of years back in one of my cleaning fits. Sorry

    I think the screen is on the petcock tube, not the petcock itself.

    Mine was flowing slow, and here's what I did:
    Took the tank off the bike and removed the petcock; first remove the fuel selector knob and then remove the petcock by taking out its two mounting screws.

    You'll see three holes that go into the tank. One is the main supply, one is reserve supply, one is petcock outlet.

    With the filler cap open and the tank off the bike, I blew compressed into each of those holes. That got my fuel flowing freely. Any crud in the screen in the tube will be blown into the tank, which means it will likely end up back on the screen at some point.

    I removed sending unit and rinsed out the tank as good as I could..

    When you look in your tank is it shiny or do you see rust?

    I'd try a big blast of compressed air through the outlet hose.
