I have gone to the other extreme and taken the screen off altogether. Makes the 12 look even more bug like now with those 2 mirrors sticking way up there. I shall see how much I like or dislike the air hitting me in the chest now instead of the head. Short ride in the rain and with no screen no turbulence at all in the helmet. Just wind pressure on the chest and forearms. Have been reading on some Yank Bandit forums that most double bubble/taller screens on the bandits just causes turbulence and wing roar. Having now ridden without a screen fitted I fully agree with this. So next step is to either buy a Chinese copy of the original screen off e-Bay for $24 or cut my ZG DB down to the same size as the original one.
