If this is like the Gen1, you can loosen the side fairing hanger and rotate it forward a few degrees. That might pull the adjoining fairings forward and give you a couple more millimeters of clearance between the tank and the forman grill. It also might cause some gaps at the ram air cover and tank cover/side faring joint or alleviate them if you already have that.
Otherwise, I'd sand it down. Draw a line with Sharpie. Don't sand farther than the line---always keep your line. Be prepared to go to some 1000 grit paper to finish it off and use 3M scratch and swirl remover with a microfiber cloth to polish out any scuffs that go over the edge if you have that happen. Clean the Sharpie off with denatured alcohol.
