Recently purchased a Screens for Bikes Screen
http://www.screensforbikes.com/
Peter was very helpfull. I ordered a light blue one and recieved a call from him explaining the one on his web site was Dark Blue which is what I really wanted.
I fitted the screen by tapeing it in the lowest position possible and going for a test run. It lived up to all claims made reducing wind effect by about 20Km/h.
I then lifted it as high as possible and found this gave me a wind vibration in my helmet.
OK so low is where to fit it for me.
Drilled holes and bolted it to bike.

You may notice that the screen actually touched the top of the front plate and the brake line. I wanted to stop that as well as be able to remove the screen quickly for cleaning or take it off if not needed.
Here is what I came up with.
I started with a 10mm allen key bolt and drilled the centre out so I could tap a thread through it.

The only ones I could get were Stainless Steel which is very hard to tap a thread in so I drilled the main hole from the top with a 4.5mm drill and then drilled from the bottom with a 6mm but not all the way so that I only had to tap about 10mm of thread not the full length of the bolt.(sorry about the blurry photo)
Then bolted them onto the bike.

Then the screen to the bolts.


Test rode it yesterday and am very happy with the result.
Only thing that I did wrong was the original two top holes needed to be about 5mm closer to the centre with the new bolts added.
I intend to slot the holes closer to the centre and cover them by adding Stainless washers both sides.
