ZX9R C2 1999 - Shushung noise

[TheGazWaz]

Afternoon all,

Just wondering if anyone else has had anything like this or similar.

It only does it in gear with the clutch out. If you tickle the throttle it doesn't do it but when you push it any further I get the noise.

I can only describe it as if you make a shush sound but loud. It's only just started doing it.

No loss of power and like I say it doesn't do it unless it's in gear with the throttle open.

Seems to do it in all gears as well.

Any Help would be greatly apreciated.

Cheers
