Hey guys, I myself as a solution to the wind buffeting problem bought the Puig flyscreen (light smoke)

Pricey, but very easy to fit, actually looks good on the bike unlike every other flyscreen made for it. Also when riding at night the top of it glows (very slightly) red, which gives off the feeling of being in a cockpit I find, always fun.
You do get a bit more of the wind thrown at your face rather than chest, but it gives you something to tuck behind (not something you always do on an XJ6N) and when you've got your head down a bit it really does cut out a lot of the noise and wind! You also finally get to hear what that delightful in-line 4 sounds like around 10k rpm (sounds like a thoroughbred).
Hope I could help you at all!
