Welcome to the forum.
It would take you less time to take the variator off and replace the variator weights with lighter ones (probably Dr. Pulley sliders in 26 or 24 grams). The belt, when under acceleration, slaps on the transmission case and cause other parts to vibrate. It is probably not the fault of the fairing.
Also, check to see if you have loose items rattling around in the front pockets.
Hope this works.
