I have a 2008 wr450f. There is a strange whistling noise coming from the engine. It doesn't seem to be related to the clutch or the rpms. But it normally happens after hard acceleration. It sounds like a tea pot.

That is probably the standard FCR whistle noise.
The Slide plate has a hole in it, and in certain throttle positions, you get a whistle sound that is constant in pitch.
If the pitch goes up and down with your whistle noise, that is not normal........
