shrill sound

Dear Members:
When I turn off my 2004 KLR650 after having run it I sometimes hear
a shrill sound that appears to be coming from where the radiator is
located. The sound stops after a while (them sometimes restarts and
then stops). The sound is not the cooling fan running. My
motorcycle is not overheating. Is this sound something to worry
about or is it normal? I can hear the sound distinctly when I put
my ear on the gas cap.
Thank you for your response.
Thad Harris

Sounds like the pressure release on the gas cap. The gas sloshes
around in the tank while you ride, and the gas cap has a valve to
relieve the vapor pressure this creates in the tank. Typically
it'll last for 10 or 15 seconds, then if you shake the bike (or wait
to dismount) it'll go again. It's normal - though your hearing
might be above normal!

What he said Thad. I noticed the same noise after I first got my A16
and put it in the shed, I thought I had a coolant leak or something.
But with my ear to the gas cap I decided it had to be a tank pressure
release.

My new '04 does this as well. It appears to be the gas tank venting
positive pressure (the gas in the tank is hot and wants to expand)
through a small vent in the gas cap. Open the cap and the sound will
go away. Close the cap, and the sound will come back.
I'm pretty sure it's normal for the gas tank to need to vent when it's
hot and the engine's off. I'm not sure that whistling like a teakettle
is normal - I assumed that something was partially blocking the vent.
But, the sound is evidence that it is venting, so I've just been
letting mine whistle, though it is a little discomforting.
With the engine running it's creating a negative pressure inside, so
there's no vent noise - it's actually drawing air into the tank.
I'm about to take mine for the 500 mile service anyway, so I was going
to ask them about it. Good to know that I'm not the only one.
