I can't see how changing the air filter or spark plugs would make any difference in this. If the engine was flooding or running very rich, your old spark plugs would have a black sooty look to them on the insulators rather than the ideal light brown you want to see. Even then you shouldn't be able to smell the fuel from too rich a mixture. I'd follow your fuel lines checking carefully for any sign of a fuel leak, especially at any connections. You shouldn't be able to smell gas unless it is actually leaking out somewhere. Do this after a short, slowish ride, because if you are riding too fast the wind might dry out the fuel fairly quickly. Are you sure you have attached the fuel line correctly again under the tank after you had the tank off to replace the air filter. Check that carefully by making sure the clip pushed in solidly all the way home and that there's no sign of fuel leaking in that area under the tank. I suppose another possibility is that your gas cap isn't closing properly, but that would be pretty obvious, and you probably wouldn't be able to get the key out of the cap either. I would definitely suspect something in the fuel line. It's possible, but highly unlikely that you've developed a crack or small hole in the fuel tank itself. On such a new bike, that would probably only happen if there was a defect in the original welds done at the factory.
