Don't know, but you might consider a very short screen. Since getting the FJ in May, and watching the forums, it seems everyone is trying to completely eliminate any wind/ buffeting.
With a VERY short screen on, the wind hits me at the bottom of the helmet. Completely clean, clear air. I am 5'10", so do a degree, YMMV. But, my torso is completely out of the wind.
My previous ride, a 2003 Triumph Sprint ST, with a full fairing, the wind hit me in the same place, and just like the FJ, 300 mile, 8hr days were very comfortable. I am 46 yrs old, not 26. Maybe everyone is trying to make the FJ into a GoldWing?
