Yesterday when I opened my left gas tank cap there was a brief whooshing sound.
I assumed a venting problem so I doubled over a piece of real think safety wire, twisted it up and carefully ran it up through the vent a ways and found nothing. I then hooked up a piece of plastic tubing to the vent, stood by the open tank camp and blew very gently. I could hear the air coming though in the tank. So basically I found nothing. I don't get it. Any other possible causes?
