Thread: '03 K1200rs windshield problem

  1. #1

    '03 K1200rs windshield problem

    I've used the windshield in the "up" and "down" positions, but yesterday, 700+ miles from home, while in the "up" position, the windshield mounting arms folded back, leaving the windshield tipped back at 45 degrees or more
    When I put it back in the "up" position, it tips back again after running for a while at high speed.
    Anyone else had this problem? What the solution?

    Welcome to the forum.
    Not sure what arms are folding.
    Are you able to post a picture?

    Are you talking about the plastic silver support arms or the little levers I have marked in my picture?

    Lee,
    The little levers. I'll try some pictures.

    There appears to be extra pieces for your aftermarket shield.
    Maybe someone with the same shield can help.

    Lee,
    I think maybe the main extra part is the dark plexi deflector. The arms are the issue. Not sure though, since the whole unit came to me this way. What are the springs in your photo?

    The springs are hidden inside the silver support arm. They keep tension on the shield to hold it in place.

    I don't remember this piece on our bikes. We no longer have them so I can't check to be sure.

    Rich,


    Welcome to the forum!

    We ask that every time you start a thread on this forum, you include the YEAR and model of the bike in question in THE TITLE of the thread. This helps in getting more pertinent answers and helps members search for similar issues with their bikes.

    Adding the year to the title of your thread, after it has already been posted, is not easy for anyone other than the moderators, so if you would mention the year in your next post, I will add it to the title.








    LONG MAY YOUR BRICK FLY!

    Rich,

    Your bike has an aftermarket windshield, and with it, mounting bits that are unique to that shield.
    As to your problem, my guess would be that the size of your shield, at speed, puts more force on the mechanism that BMW supplies which is designed for the smaller stock shield. That force causes the shield to collapse.
    In truth I'm not clear on your failure mode, so I can't suggest specific approaches for a fix, but in general terms your options are clear.

    Slow down (LOL!)
    Switch back to a stock shield.
    Redesign the pivoting mechanism in some manner to allow it to withstand greater wind forces.

    And just spit-balling here: the K12GT of the same generation has a power windshield system. It might be possible to integrate that mechanism which may be able to better withstand the deflection forces.

    FWIW, stock shield down and up, attached and I have no idea why they are upside down. Sorry.


    Good luck.

    Same for me.
    He says the shield tilts back 45 degrees.
    I wonder if the shield is just dropping to the low position.
    If it's dropping to the low position it's probably due to the oversized shield.

    Thanks, gentlemen.

    I took off the shield and lubed and tighter everything without taking off the silver covers. Went about 5 miles towards home (in Georgia) from my daughter's (in Illinois), and the silver cover came loose on one side. I stopped.

    Tornado warning was issued, two kids (tracking me on Google maps) called to tell me that I was stopped in the wrong place and a tornado was coming. Headed back, and the windshield came entirely loose at the bottom
    Arms broken on one side, and plexi broken on the other.

    I've repaired the broken arm with JB weld, hopefully it will hold until I get home at least. It was most likely broken for some time, causing the original problem. For what it's worth, there has been quite a bit of vibration on the windscreen for some time, and I suspect if I had taken the time earlier to tighten everything, I wouldn't have had this problem.

    It's somewhat hard to describe the actual failure mode, and I'm assuming that the windshield on this model has only two positions, down, and up. In the up position, both halves of the upper arms on each side are aligned perpendicular to the windshield. In my case, the wind, vibration, and probable broken lower mount allowed the windshield to raise sufficiently for the outer portion of the upper arms to fold back.

    Don't know if parts are available for replacement, but will look after this post. Sorry, but I didn't take a "before" picture - but am attaching an "after" of the repaired part.


    Also, my K1200RS is a 2003 model year, sorry for the omission.

    Thanks for the update.
    Yes, the shield only has 2 positions.
    The lower arm part number is 46 63 7 658 866
    Are you sitting down? The cost is $59.43 for one.

    Make sure I pictured the correct part.
    I have a broken shield arm from Deb's 03 K1200RS and it looks different compared to your picture.
