Stats:
Me; 6'3".
Bike 2010 XT660Z, standard OEM seat, standard screen, Arai XD4 helmet, bar risers, Wolfman Blackhawk tank bag (most of the time).

Problem; buffeting, turbulence, helmet peak vibrating at speeds over about 45mph.

I noticed that when I stood up on the pegs at speed, everything got much quieter, and my helmet peak stopped vibrating. I removed my screen altogether and the buffeting is much reduced. I can actually feel the vents in the helmet flowing air, and doing their job. It's still a little noisy, but much more comfortable. Without the screen though my GPS is left quite vulnerable. Does anyone make a low screen option for an XT660Z? If not, what's the best way to approach cutting down the original screen with minimal chance of wrecking it.

Cheers, Rich.
