Odd whistling sound

ok, not sure how to explain this one, but when I making a left hand curve and get my ass up out of the seat and offset it I hear a very faint whistling.

It almost sounds like wind whistling, which is what I thought it originally was.

Well, I tested it over a few miles, and I can recreate it at any time and it is only when my weight is shifted off the center of the seat on the left side. I can even get it to do it when not turning, just by offsetting my weight. Although, if I just lean into a lefty keeping my ass centered it does not happen.

Any Ideas? As of today it is too cold to go putz around the block to see if I can pinpoint (25 Degrees and snow)

I know its a shot in the dark but thought Id ask. Bike is at 12.5k and is going in for 12k service soon anyway, just bothering me.

Do you wear pants when you ride? I've heard this often happens to naturalists when they ride. You notice it only happens when your bum is out of the seat over to the left. Most men dress to the left too, so it probably comes down to your personal aerodynamics. I must say you are very brave to ride in this condition at that temperature.

At 25F and snowing, my "personal aerodynamics" would not affect the airflow at all but, is your knee pushing the fairing out at all? Is a fairing clip broken/not seated?

Most likely it's your tire. Some threads are louder than others. Could also be the wind hitting your helmet at a certain angle.

Nothing to worry about.

yeah, not riding in the 25 and snow, but it was 70 on Saturday when I went out for my last fall ride.

I know its not the wind, as I checked it over numerous miles, and the front tire is a PR3 new this season with about 7500 on it, will check that again. Wouldnt have thought the tire would make that sort of sound.

Thanks for the input.
