ZXR's are generally noisy, one rattle comes from the clutch which is normal, that usually goes a bit quieter if you pull the lever in. Top end is generally noisy too. If your not sure get a dealer to check for you, better safe than sorry.

You can check yourself by looking at how far the tensioner has extended, down by the pickup coil. It could either be a worn cam chain guide or the chain has stretched.
