    My Biggest Dumb*** Move

    99 R1100RT

    Taking my tupperware off today to perform brake line maintenance and front shock replacement. Have done this once before with no problems. Today I, get this, broke off not one but both (left and right sides) of the fairing tabs at the bottom with the two holes that secure it to the shark fin piece (I think I have named that correctly).

    I've done a lot of dumb things in my life but this has to rank right up there at the top of the list.

    So naturally my first thought is I have to buy some used replacements. Found a left side in good shape (graphite color) on Beemer boneyard and almost clicked the buy button before I got a hold of myself to consider other possible options.

    So, my question is (figure I am not the only one who has ever done this) are there any repair options available and/or what are the ramifications of just using the fairing panels as they are (i.e.- would it flap around in the wind, make noise, etc.?)

    Any thoughts or suggestion would be appreciated...Bob

    I think I did the same thing you're describing. I ended up using a hair dryer to take some warp out of the plasticÔÇöwhich is what stressed it in the first place. After reshaping, first i glued it to the support beneath, and then to the main body where the seam is. I used JB Weld and fiberglass cloth to reinforce, in those two spots. There's a line at the repair but very hard to see.

    The bike is 14 years old. Drill a few holes and pull some zip ties through them. Problem solved.

    Hi Bob,
    sorry to hear about your fiasco--similar fate as of late--it is possible to repair and is not rocket science--will however take a bit of time and effort--I would start by recommending you purchase a book called "How to Repair Plastic Bodywork" by Kurt Lamon available from Whitehorse press for about $20--you won't regret it--very informative, straighforward and clear--there is a section in the book pertaining to exactly the type of repair you have in mind....forming a new piece which you broke off--

    using silly putty you can make a mold which is attached to the body panel and is filled with a two part methacrylic adhesive--when this cures (about 1/2 hour), the mold can be removed easily and the new addition, which remains somewhat flexible like the body panel, can be shaped and drilled with a Dremel tool--I was pleasantly surprised at how easily it was accomplished--you can see my first attempt at this from the photo--If you want, let me know and I can give you the brand of adhesive I got from an auto parts store for about $6--

    aapasquale, I'd like to know what the two part adhesive is. Please post it here. I have some broken tabs on an airhead side cover that I've been wanting to fix. Making a mold out of putty sounds like a way better idea than using pvc pipe cuttings and JB Weld which I've been contemplating.

    Thanks for this info. I would like to know as well what the adhesive used was. Making that mold sounds complicated, but maybe I need to read the book first. I am going to try and post some pictures of what mine currently looks like. Thanks again..

    I will post some pics. The one below is from the right side fairing and shows the three broken pieces. Note the previous repair by PO:

    This shot is of the broken piece off the left side fairing. I have shown it close to the actual attachment point. This one looks doable as it is only one break vice the three pieces off the right side. Also note the heat damage in the upper right area of the photo. I suppose this is fairly common on these machines?:

    Bob, That's just like mine. And I see some heat damage to the inner piece. What I did was: use heat to take some heat warp out of the part underneath where it was originally welded, then glue/cloth the tab to the inner part. Wait for that to completely set, then glue/cloth the tab where it is broken to the main fairing. On the second step, put a good reinforcing layer of glue/cloth on the back side. RB

    the adhesive I used is a two-part adhesive called PermaPoxy (5 minute plastic weld) manufactured by Permatex--It's very easy to use--Bob, in the book you will see other ways of repairing your part which are even more appropriate and are very well-explained and you will no doubt find it a great learning experience--all the best

    I had the same happen on my 800.
    I used some metal and some epoxy, on the back side.
    It worked fine, in fact still works.
    And didn't show at all.
    Use an epoxy that is compatible with your plastic, I think the 800 is ... oh, some letters. It's a code on the back, usually.

    A copy is on the way. Actually got it for $13 from Amazon. I look forward to getting into it the latter part of this week.

    Dumb move

    I have done the same thing. I rigged up something but its been so long I don't remember how I fixed it. I know I didn't buy a replacement.
    I will tell you that it is so far down the list of dumb things that I have done that it is not in the top 100. Don't get me started on my dumb moves.
