An Update,
I have now had the bracketts made and they are now fitted to the bike. It has taken some trial and error to find the most suitable position. At present the screen is at its highest setting and at it's most elevated plane.
I can now ride with my goggles up without problem and most of the buffeting is now around the edges of the shoulders, but not in an annoying way.
Together with a big foot stylee stand puck it cost me £30.
Regards DWC
