Rt handle switch box and grip Loose

[dvfr750f]

The switch box and grip are loose, on my 81 CBX.
I think I can hear something rattling around in the box.

How do you remove the box and tighten up this situation?

Are you talking about the handlebar switch and the throttle grip? There are 3 screws on the bottom half that thread into the top half on my 81...have you checked these? Be careful not to move it around to forcefully...alot of wires inside...don't pinch any.
