May not be coming from fairing.
Batwings are notorious for amplifying sounds coming from elsewhere.
I had a vibration that drove me nuts for damn near a month. Had fairing apart half a dozen times.
One day I rested my hand on the fuel console door.......
OTOH, batwings are prone to having their support brackets break. Taking the outer fairing off is no big deal, have a peek at the brackets.
Happy New Year
