Sounds like a very good idea to me have been experimenting with my screen, one of them Teutonic flip things that doesn't work, see my post screens a slight improvement on the other forum,

 :-X I have never lost a set of keys until recently ' the Kemble air show, these were left stuck in the top box lock and disappeared en route to Glos'ter. Just had new Ford car etc, etc, replaced fortunately insured with Boomerang Tag costing over £200. The day after they were replaced, guess what arrived at Tesco no keys!!! left them in the topbox again!! They were still there. Have I lost the plot? Well yes but the KEYPASS KWAKER thing has got somthing to do with it, as the ignition "key" just sits in the zipped pocket of my jacket. Will stick a label on the windshield Keys you ------- idiot!!!
                           Sure this will catch someone else out, beware.       The Rat
                                                                                         
                                                                                                     
                   

My lad is into flying and recently went solo in a microlight, a Eurostar, at the Flying Shack @ Gloucestershire airport (formerly Staverton). The view of the airport is second to none, the team at this newly formed enterprise are very friendly, to the extent that I spend quite some time avoiding DIY etc ,sat drinking tea observing whats going on.
If you are interested in flying or just having a look, a cuppa etc, just pop in, beer can only be sold to associated members (£10), you can't miss it, someone has placed a Vulcan cockpit at the entrance!! I am now trying to loose three stone so that the lad can really scare the S--- out of me, 15 stone is the limit.
                                GTR is often in the car park, nice to meet some owners from the local area.

 ;)Had a look at the beast again, it seemed then obvious that a fairly simple attachment to the original mount would give adjustment to whatever screen you have. If you used the original screws to bolt a retangular bar of X thickness, extending upwards by about 125mm, then  the screen can be attached at experimental heights in any position you like. It will not return to the flush lower setting and be forward by the thickness of the bar, unless you make a dog leg affair.

Note the Kwaker mount is curved, and the MRA screen is curved, but not the same curvature!! at least on mine, initialy this could be allowed for using a feeler guage and washers, perhaps when proved a nice hand fettled bit of ali or casting could be made.

A Rolls Royce job would be to piviot the top mount and make the botton adjustable, ie in and out therefore altering the angle of attack and the "letter box scoop at the bottom of the screen to eliviate the percieved low pressure behind the blade. Time to get the files out and set the mill up.

 :oNever seen a Rifle base but i see where your coming from almost two screens sandwiched together, perhaps a very simple slot or handle at the top simply pull it up, to prove the principal and ideal height, then think about the mechanism. We have tiny stainless chain at work, there are very small cylinders etc. I think however two minature rack and pinions possably connected by a fiberglass drive shaft (like tent poles only 4mm OD) could curve with the screen and provide drive, via a knob at one side , the rack ensures squareness and stability infinate adjustment on the move and the potential to attach power.
                                                                Spacers my first port of call I think should be 30mm wide at bottom, 16 at top, might bash them out of wood first. Note have used wood in experiment many times, in one particular incident, a jumped up half witt (manager) at work attempted to ridicule a similar suggestion, I was not amused and had to point out that some guy called Geff, i think, Dehavilland made that bit of crap called the
                                                                              Mosquito out of wood, enough said   Rat.
                                                                                                                                             

 ;)I'm sure you are right ,my suspicion is that the original manufacturer Kwaker knows exactly how to cure this ,the solution would probably be move the screen well forward (like the Guzzi) but this doesn't look right or "sell" the bike, which is one of the smartest looking sports tourers. As mentioned would have thought by now a design graduate would be posting photos etc of different design screens + riders with air flow in a wind tunnel. May be they have but I haven't seen them? A lot of the claims from manufacturers are simply not right.
                                                                 might make a couple of ali spacer bars to move the screen forward and sharpen the angle, by doing so the letter box becomes larger and would have more of a scoop effect, i'm sure it can be improved.

 ;)Thanks for that, like me you seem to have been round "the mill" i take it you are well over 6 foot, it is strange that all these claims for screens can't be correct. One screen I try'd claimed that the inner pressure behind the screens was increased forcing the airstream up at the top of the blade by  two holes/cut out at the base? The cut outs were very small and no attempt to smoothly bend the air up inside the screen. Frankly i thought it would just create turbulence, and noticed on both the FJR and GTR that there is a letterbox cut out channel anyway?

                                                                              Odd regards Rat   

 :-\ Owned numerous bikes, naked, street fighter, tourer etc, etc, all those dedicated to fast touring have had issues with the screen. ie FJR, Strom, GTR, I have tried many types including those tested and developed in the aero industry in the States, frankly all did not work for me, 6 foot tall, some were far worse than original and all a disapointment. the last one bought was from  MRA I think and that didn't seem to work either, the flip up bit was not particularly well made either. However I persisted and have found that will flip up to max, and screen up to max it is slightly improved enough to be whatching the speedo as triple digits arrive with ease. I,m almost certain that a slight rise in the "Flip bit" or mounting slightly higher, or slightly bigger would improve it further, a Gel seat ie lowering a inch would help to.
       
                                 Can't understand why some boffin at Uni hasn't studied this, so come on instead of fitting concrete blocks in the nose of a Euro fighter (87 million each) sort bike screens out, please!!
                    Note only bikes the screen worked 1/ Guzzi Cali EV, large, Flat, Why? but well forward?    Aprillia Falco double bubble more sports but generaly absoultely great  Regards the Rat
