Whistling noise

I can't figure this out for nothing. Thre is a whistling sound coming from the gas tank when my bike is off and parked. What could cause this and how do I fix it?

Check your overflow hoses at the bottom of the tank. They may be pinched and it is forming a suction from the fuel pump drawing fuel out and is sucking in air to compensate for the fuel loss. If not that, unplug your fuel pump and see if that stops it. It may be staying on for some reason.

It is probably very hot where you are, check and see if the fuel tank cap is venting.
When it is whistling, open the gas filler. See if it stops.

Mine does the same thing. The tank is sealed (for the most part) and gasoline is a very voilitial liquid... it vaporizez and the vapors expand at relativly low temps. The flash o[point is around 74 deg F. The whistling is the press from the engine and ambient heat causing the fuel to vaporize and expand.

Just, with 2 hands, pop the cap and reseal it. No worries. (anyone got a match?)

I have 2003 with 400 miles on it... it whistles, too. Seems to a normal thing when it's hot out. (So Cal) No worries, me thinks.
