Word. I shudda took it in yesterday.I would take it back to your dealer as soon as possible to have them fix it under warranty. If you can smell gas then don't park it near any open flames like a water heater or a lit cigarette. You don't want to mess around with any fuel leaks. The air pressure sound is because the fuel tank is sealed(on bikes with a vapor canister) until you open the cap: it's normal. Good luck.
