    Trimmed the lip of what? And to what height? And what is your height? (others would benefit from knowing details of anything that works well. thx)

    Hi,

    Just wanted to drop a quick after action report on the AeroFlow tall windscreen for the GS1200.

    Installation was a breeze and the instructions were very well thought out.

    The screen works GREAT. My neck doesn't feel pounded from buffeting after riding anymore.

    Noise while riding is decreased but still louder than I want to take without ear protection on long rides.

    The only downside that I hadn't anticipated is that I can't run my H&P upper crash bars as they conflict with the new windscreen.

    Ever seen a stock 1150 GS screen? It has a lip at the top, that's what I cut off. I'm freakishly tall, and wanted my mug in fresh streaming air, no buffetting, so the lip had to go. The other trick was to drill the cleats for a lower setting, the screen is laid way back, simply perfect to have my helmet in clean air flow with minimal (for a GS) turbulence.

    Hello everybody!

    A bit of feedback and a question!

    I've just recently purchased a Givi Screen for my R1150GS (coz it was cheap! and I had a bingle), after running Tobinators and stock screen, and a locally-made screen Which is like the Z-technic screen.

    I found that as soon as you go over a certain 'tilt' of screen you go into a noise/ buffeting zone, tobinators or not. I am interested in trying the Wunderlich one piece that has won acclaim in this thread but I feel there is more to it... see below.

    The Givi screen is the quietest and smoothest so far, in the laid back position, Tobinators or not. I am happy with this as an 'all-ride' screen. I feel this works well, as I'm sure do the Adventure screen, Wunderlich and others without a lip or wide upper sections. My goal is some wind, but smooth air with minimal noise. Popemobile/ LT luxury isn't a priority. I'm 5'10", average inseam with wide shoulders. I wear a shiny new (well, matt new) Shoei Multitech Helmet. I have handguards which I'd prefer to retain.

    I am going to make or purchase some various deflectors and try them out (like R1200GSA) purely for the sport of it! I see some 1200GSA items fitted to an 1150, which I might try.

    I feel that the dead zone behind a more 'vertical' or larger screen on any GS is affected by air that comes up from beside/ underneath. I see another member has made some for his bike, and reports well, as do most R1200GS owners who use GSA items, who have less 'lower' protection (narrower tank etc) than an R1150GS. Hence the reports that tank panniers work well.

    The other noisemaker/ buffeter is the 'lip' on the stock screen, and as I mentioned before, it's angle. I see another owner has chopped that lip off, and angled the screen. I can see how that works well. If I had a spare screen I'd try it!

    my question is:

    Are there any aftermarket manufacturers of winglets for R1150GS'?


    Thanks to all. This problem, for a lot of people, seems to be their greatest, and the solutions their most individual.

    I am afraid the answer is no. As you can see in the hereunder thread many (among which i am) did the same research already .

    Is this common on the 1200GS? I'm ready to mount one and running into the same problem. I have a drill in hand ready to go, should I plunge it in there:puke1 or get some other means to mount this?

    I had no trouble installing the Givi on my GS. Everything fit well.

    Speaking of....

    I'd like to try the Touratech spoiler on the Givi, but I don't know whether to order the 1200 GS spoiler or the 1200 GS ADV spoiler. I know some here have put the TT spoiler on the Givi screen, but I didn't see any references to which spoiler they used.

    Well, I went ahead with the drill and it went fine :clap Here are some pictures of the final install. This is the Givi screen with the Cee Bailey Wind Wings. The total cost was around $200

    Hello everybody.

    Before I lashed out a new ADV. scren etc, I've done something crazy and in a fit moved the tobinators angled FORWARD slightly, at the front lowest setting, with the givi screen. The screen is laid back a touch more than the original 'low' setting.

    I had tried a lot of other tobinator positions and found reduced buffeting, but various problems with wind noise and airflow (rain just gathering on visor, no de-fogging airflow). vast improvements over the stock screen, the Tobinators have helped immensely. I was sure there was a way to reduce wind noise.

    well f*ck me. :huh the quietest it's ever been! still plenty of air to clear visor of rain and fogging but I get no buffeting and very little wind noise. I'll fine tune it and post pics and dimensions. if the screen were wider I'm sure it will cut out side winds better (we had some windy days and you get some wind noise then)

    I've tried some winglets but found little benefit, but I think the winglets on an 1150 need to be at a more vertical plane to be of assistance.
    I'm designing some :norton


    I've had a few attempts at wind noise but am suprised that this worked so well, but when I analysed the result it made sense. I feel you need more air under a bigger screen, if that makes sense to equalise pressure when you sit so upright, when there is not enough width in the fairing/ screen in comparison to height. bigger screen needs more width from the bottom (hence winglet success on 1200's, esp. with big screens).

    Currently I have a 'motorway' commute which I can use as a test zone on a daily basis, and trying a full range of settings has netted this result. I can only suggest people still trying for a bit of quiet to try this setting.

    :clap :clap :clap

    It took me long to find the right stuff but i fount it.
    I already add the CeeBailey screen, i added the 2 winglets such as the R12GSA (home made) and a couple if other to avoid the airflow to being directed from the handle units right on my arms.

    ... meaning this post will be for questions :D:D. Here below a detail of my GIVI mounting:

    [​IMG]


    Questions:

    1) On mounting the new givi, I didn't know that I had to dismount the black plastic part from the OEM screen, used to setup the screen. The two black handles on the side of the screen (only the right side in the picture). It appears that there is a L and R. Did I mount them correctly? I mounted the L on the left (obviously !) looking at the screen FROM THE SADDLE. Did I act correctly?

    2) To compare with your mounts, consider that the black handles are asymmetric. You may notice the black plastic between the screen and the frame. The thick part is on top, the thin on bottom. Is it the same on yours?

    I'm asking this because, after the mount, I can barely screw the 'safe bolt', the one that is inside the cockpit, on the same axis of the plastic handle. That means that if a need to move the setup of the screen I need a tool. With the OEM screen, I just have to unscreew a bit the handles to loose a bit the screen for the new setup.

    Heeeeelp! :eek1:eek1

    3) Is anybody 6.0" here happy with GIVI+Winglets? Where did you setup it (notch)? I had the stock screen+laminar lip before. I didn't notice such a big improvement with the GIVI.

    Thanks for any help/suggestions! :deal:deal:deal

    Bye

    Is that top piece off-center, a little too far to the right? Just curious, it would drive me crazy having something asymetrical in my field of vision.

    No, it just comes from the picture, in reality it is right in the meedle.

    I took some close up photos of my installation and posted them in my 1200GS thread. Hopefully you will see something there that answers your questions.

    Bike: 1150gs
    Size: 6'2", 165lbs.

    Bike came with aftermarket screen, I think it is an Aeroflow. I wear foam earplugs 99% of the time and ride the bike everywhere: last year from Cali to NY and back; on hwy 1 (55-75 mph, strong head/tail wind) a minimum of 200 miles/week; around town; fast mountain roads; and longer trips on I-5 and 101 (65-80+mph).
    I've read all the threads about noise and screen problems and possible solutions and have tried a few of my own. Here is what I have learned:

    1. The worst noise problem for me is buffetting--my head being shaken around and low frequency booming in my ears. Even with earplugs, I believe this is causing serious hearing damage.
    2. The booming seems to be a result of the screen being too far from the rider. If I lean way forward, I can usually find a pocket of good air. If I stand up, the clean air is MUCH less noisy than when I am behind the screen.
    3. I tried a homemade 'rumble strip' on my helmet--a piece of foam that is supposed to interrupt the air flowing over your helmet resulting in less turbulence/buffetting from behind the helmet. You can google it--didn't do much if anything.
    4. I tried taping things to the screen to break up the air and minimize vortices--little if any affect.
    5. I bought a windjammer 2 and so far this has been the second best solution so far. It stops air from shooting up the bottom of your helmet after if hits your torso.
    6. I removed my screen. This was the most pleasant riding experience so far; both for the quiet, clean air and the beautiful, unspoiled view---until I ran into a headwind at 75 mph. Then it was almost unbearable. Also, the front end felt much less stable on HWYs at speed. Probably a result of less downforce caused by wind traveling over the screen.

    What I have learned: Up to 75 mph, in calm conditions, taking the screen off was the best solution. My neck worked a little harder against the wind hitting my helmet but it was well worth it. Since I often ride in windy conditions, I have my screen on, the windjammer 2 in place and earplugs in. So far, this seems to be a good compromise. If I know I am going to be on the freeway for more less than 45 minutes at a stretch or that there isn't going to be much of a head-wind, the screen is going to come off, period.
    I hope this is helpful to someone as all your other posts have been helpful to me.
    Another rider summed up what I have also found to be true:

    "Buffeting is caused by turbulent airflow, usually from bad windscreens. It is definitely worse than clear airflow, which will cause noise around ANY helmet. If you can get a small screen which breaks the windflow off your chest, eases the drag on your body, but lets clear air flow over your helmet, you may be better off than hiding behind a big, vertical screen which causes a very abrupt break in airflow-the resulting low pressure area behind the screen causes the turbulence to be sucked down on your head, causing the dreaded buffeting. It batters the helmet, working your neck, as well as creating noise. Bigger is not always better-that being said, I have been behind screens that were oasis' of calm. Lovely. Individual helmets will vary even with the type of riding gear worn-seriously, different jackets(armour etc) will affect the noise. As he said, wear earplugs..."

    For what it's worth:
    10 months with my 1150 GS so far, 6' tall, 32" inseam; here's what I have tried so far. Took off the stock screen and put it on a shelf in my garage. No screen = BIG improvement but a little breezy in the colder months. Tried a Givi this spring, in the lowest position it gets noisy around 50 MPH or so, unbearable at 70 unless I scrunch down in the saddle or lay on the tank (like some of the sportbike kids do). Yesterday I tried the Saeng edging on the Givi, and it is a noticeable improvement: still a fair amount of noise, but much less buffeting and a lot more comfortable. Looks cool, too. I'm still not sure it's better than no screen at all, though, at least in the warmer weather.

    Cheers

    I'm about an inch or so larger than you both in height and leg - does the front high/rear low configuration work well? I'm looking for a solution without going to a low uncomfortable seat.

    JimO: Would you please add the Adjustable Ztechnik screen with tobinators to your list. I just installed the setup and am in the process of finding the right adjustment. Much better than stock. If anyone has used this setup, I would be interested in any info I could get. I think it is going to work very good. Has many adjustment combinations,

    The best $117 I spent so far was the Touratech windscreen spoiler. No more buffeting or wind shear. Its also on and off in seconds and fits nicely in the tank bag for off-roading. BTY its on a stock 07 GSA screen.
