I'm really not having any issues with buffeting that a lot have mentioned.....for me it is the wind roar that is bothering me the most. I know what you mean about having calm wind behind the shield.....that is how it feels behind the shield of my VTX and that is what I'm trying to duplicate with the King
i had an 08 road king, i but the deflectors on and i got wind under my chin, i took them off...better without them. i then cut my windshield down and it did the trick
I installed the fork deflectors and they helped a lot with wind coming up from under the windshield. At first I didn't care for the looks of them but they grew on me and I really like how they work, especially when it's raining. I tried the fork baffle also and it didn't make any difference so i took it off.
