    I installed my BMW winglets (slipstream deflectors) last night. As i pulled the beak off I noticed there were no nuts to thread the screws into.
    My dealer did not provide nuts. Now I read here that there are also supposed to be washers in the hardware. My dealer did not provide washers. Nor did he provide any instructions. Also, it looks like the dealer provided screws that are too short...can someone tell me how long these screws are supposed to be? The ones that were provided are exactly the same as the pointed torx screws that are used as the beak fasteners to the frame.

    Can someone explain how this is supposed to go together? Here is what I assume to be the correct mounting method:
    1. Insert the 4 black bushings in the four holes in the 2 winglets.
    2. insert the flanges into the black bushings so that the wide flat is on top.
    3. screws goes down through.
    SO...where do the washers go??? Don't you want the rubber bushings in contact with the top of the beak paint, and not the washers?

    Thanks

    The only thing that bothered me about the winglets was the reflection that they produce. After awhile I got used to it.

    My 07 does not have that flange for the accessory socket. I am sure of it as my winglets are merely bolted down on the fairings. I hope they hold.

    Per diagram and looking at a 2012 GSA at the dealers the washers should go between the winglet and the fairing.

    Worrying about if they will scratch the fairing seems odd as you have to drill holes in it already, but to each their own.

    Last fall I installed the winglets on my 09 12GS. A big help in the buffeting! Recently (again from reviews here and a UK forum I discovered) I added the 2-piece Givi windshield/screen. Now for the first time since 1995 (2 GS's) I can ride in comfort! One odd thing I noticed even before adding the winglets and even more so now, is that when I ride through a lengthy interstate tunnel (av. 65-70), it is dead quiet on the bike. Anyone have an idea why that is so? It's like riding in a vacuum.

    I guess the bikes are different depending on the year. My 2010 has the nut plate already install under the faring. The hardest part was lining up the hole to drill through the faring to hit the nut plate.

    I can report that the winglets DO cut down on the noise and buffeting significantly. I'm still running stock screen (09 GS)

    That is where myself and a friend put our rubber washers. Lining up where to drill the holes is tough. Start small and look to see if it's alined correctly.

    I can say that both of us felt very little difference in wind noise or buffeting.
    I have two different screens, neither stock, and my friend has the lowered version GS with the lowered seat and stock shield.

    Wind noise and setup depends on many factors.

    Just FYI, I stopped by A&S Cycles today and they had the winglets in stock, so I told the parts guy I wanted a set to put on my GS. He got me the winglets, 4 screws, 4 steel sleeves, 4 slip-nuts, and 3 grommets. That was all the grommets he had in stock, so he had to order 1.

    When I got home, I took the winglets out of their boxes and discovered that they already had grommets installed! And, yes, the boxes were sealed.

    He did not even try to supply plastic washers. I looked at the fiche on Max BMW's site and it shows the plastic washers, but says they're "NA". So, I may go by Lowe's or someplace and get some - or I may not.

    My point is simply that, if you're ordering these parts, I don't think you need to explicitly order the rubber grommets. Just the winglets, screws, sleeves, and a set of slip-nuts (which are not shown in the fiche). And you only need the slip-nuts if you have a later model GS that has the mounting flange for a powerlet socket and the winglets already under the fairing. My '09 does have it and I think all later ones do. Not sure about earlier years. But, without that flange, you'll need regular (Nyloc) nuts or well nuts.

    Final update: I finally installed my winglets. For some reason, though I did read MOST of this (very long) thread, I was under the impression that the winglets would fit with no interference from my stock '09 GS windscreen. I was wrong.

    I cannot use the 2 or 3 highest positions of the stock windscreen, with the winglets installed. I will have to trim the bottom corners of the windscreen before I can raise it all the way.

    I do remember reading where some posters had similar issues but, for some reason, I thought the stock windscreen was supposed to be okay. Obviously, I was wrong. And I looked at a couple of new '12 GS's in the shop at A&S and their windscreens were the same as mine.

    ps. a 7/32" drill bit made the perfect sized hole in the fairing, to insert the winglet screws through. a 3/16" hole was just a touch too small.

    I went into Max's BMW today and told the parts guy what I wanted to do. He knew exactly all the parts and threw an order together. Came out to $92 bucks so maybe they went up just a little. Anyway I'm looking forward to trying it.

    For those looking to try this with a 2010-2012 GS, here's my experience:

    The wings ordered from A&S do come with the big black rubber grommets already installed, so those weren't necessary.

    There's a metal flange on the frame that has the screw holes for these already.
    To line up the holes perfectly, there are 2 options:

    1. go underneath the bike with a felt tip marker and push it up through the holes and mark the underside of the beak. Then remove beak and drill (tape the topside and go from small bit to large bit).
    2. one of the bmw places heats a coat hanger to red hot and pushes it up through the holes on the metal flange without taking the beak off the bike to melt holes in the right location, then they expand the holes with a drill.
    3. if you have a small enough drill or a long enough bit, you could potentially drill right through those holes and up through the beak without removing it. I've only read of one person doing this, and I know that none of my drills would fit in there.

    I opted to mark and remove the beak. The hardest part of removing the beak was figuring out that you have to lift up and rotate outwards on the aftmost bits to unhook them before you could slide it off past the frame. Getting it back on was easy, getting it off the first time took some jiggling and headscratching.

    You'll want to order 4 u-nut's or clip-on nuts (as the bmw guy called them) to screw the screws into. These slide right onto that metal flange. Cost: $5.80. They're the same as the other clip-on nuts that the faring screws mate to.

    On my 2012 GS with ADV windscreen in the lowest position and the seat in the high position, these help a little but not a lot. I'm 5'10 with a 30-31" inseam. I still get buffeting and wind noise. I plan to experiment with the screen position and the seat position, and maybe put the stock screen back on or order a givi or calsci for comparison.

    I did not remove the beak on my '09. I used my regular Makita cordless drill and a normal length 7/32" bit and drilled through the holes in the flanges from underneath. It wasn't easy, but it wasn't that hard, either.

    I just finished reading this entire thread and didn't see anyting about fuel economy. For those who have installed these wingletts, has it affected your MPG? If so, in which direction? Up or down?
