high pitch whistling noise

Hey there everyone. Been riding my 2002 DL1000 for a couple weeks now and I can't help but notice a high pitch whistling noise when idling or in motion. Maybe it's the cooling fan? Any ideas of what it could be?

If it is the cooling fan it won't turn on from start up until it gets fully warm. If the noise is present when the engine is cool, it is not the fan

It's after it warms up. It runs fine. Just an annoying noise..

Sounds like a vacuum leak that seals itself after expanding. I'm not familiar with the 1000's but if it has a fuel pump, immersed or remote, It may make more noise when cold. The 650s, like some other makes, make a whistling sound from the cams/cam chain interaction.
