On mine it already had tape with a 3-5mm floam on one side ,like the ones you use to put around your doors archs to stop them shaking in the wind, go to the hardwear store to get some.
You probably will see the tape already ,it will go between the edge on the black plastic part of the screen and the fairing.
Or you the screws might be loose ,either way see how you go and report back.
