Where is the gas tank vented at? When my fuel level goes down (as I'm riding) it sucks my tank in. I rode on sunday for about an hour and a half with my boy and then parked it. It had 4 bars when we started and was down to 1 bar whaen I parked it. Last night when I got home at 5:30pm I went out to put them inside because it was raining. When I went to start the Nytro I noticed my gas tank was collapsed. It even poped out the panels that cover the tank (which is the stock tank). So my question is Does anyone know if the tank is vented. Thanks 1050
