I moved the turn signals below the lightbar spots, and have Ma's crashbars. The lowers had to move down the fork leg to clear the turn signals and they just contact the crashbars.
Got mine based on Todd's research (thanks again Todd). If you get head buffet that decreases if you move your left arm across your chest, then the air is coming from around and below the tank and the lowers should resolve this. It seems to be prevalent with larger windscreens. I'd recommend them especially if you have a large windshield and do a lot of high speed highway travel.
