Perhaps this is a rediculus question but here goes. Whenever my 400 is cold and has just been started, it makes a wierd whistle/whining sound when i give it a little throttle. I know the cam chain makes a whirring sound kind of like a supercharger, but this is not the same sound. it's louder and only does this when it's cold. it runs fine, and has done this since it was new. ony suggestions? maybe this is normal?
Thanx
