    A heat gun on low setting for about a minute and it was nice and pliable and didn't go out of shape.

    If you're not seeing any metal banding you should be fine. There is a layer of metal mesh in the middle of the material.

    I heated mine over an open flame (my stove!) for 30-45 seconds to get it hot enough to bend. I tweaked it more round, and out away from the bladder. I ended up having to take about 2" off the bottom edge so it didn't touch the rear tire under compression.

    Just heard from my dealer - my rear shock will be replaced under warrantee (~6,300 miles).

    Thanks for the feedback Cruz & JD. Do you think with the shorter guard you now run the risk of gravel coming off the wheel and damaging the shock?

    On another matter this is a fantastic forum, but Im having a bit of a problem with this thread, messages disappearing and pg9 disappearing. Is this common?

    I had a small spot that worried me, this is what I did.
    It was a warm day, concider this if you attempt this fix.
    Like you, I did not like the washer fix, it didn't seem to work right.
    On a warm afternoon-90s, I took the tail of the flap and bent it up, against the tire, so it was pointing against the direction of tire rotation.
    I left it there overnight. In the morning I flopped it back and used a hairdryer to get the right angle plus a little since I figured it would resist my efforts.
    Well, it worked. My tire has cut a small semi-circle in the bottom of the flap, but not enough to let any mud or debris onto the bladder and it does not rub on the bladder.
    I concider it fixed.

    Is yours still under warranty Muddler?

    I'm heading in to Auto Classic in a week or 2 to hopefully pick my bike back up and I'll ask them what the deal is cause mine has the same issue and I only had mine about 9 months

    Why not, too easy? :D And you didn't spent alot of time and money? :D


    I ride east coast enduros and RallyMoto events, also spend many miles on sandy whooped out sections in the pine barrens and have 9000 miles on my bike since the washers were added, no flat spot, no leak.

    Just wondering what you think is wrong with that fix.:ear

    personally i don't think you should have to fix it. I'll get the shop to do it incase it still suffs up, getting the most outta to 2 year warranty ;)

    I replaced my air shock with a Wilbers before I even had 1000 miles on the bike. Not so much that I don't like the idea as much as I did not like the "buck" effect when I grab a handful of front brake.

    Anyway, it sets in the garage unloved. If someones air shock dies and can not get it replaced under warranty, and, doesn't want to shell out the BIG $$ for a coil shock I'll make you a great deal on mine. I'm not actively trying to sell the thing but if I can help someone out I will.

    Im the same as Olyflyer, if its still under warranty Im want to make BMW fix it. I tried sticking some washers in but didnt really like the look or the fit, so I decided reforming the guard would be better.
    Im sure the washers are quite functional though

    doesn't seem like any air got out but has anyone experienced this and how do i fix?

    thx in advance!

    Does the shock still look straight?

    from the angle in the picture you'd swear something inside the bladder got bent or broken.... ;-(

    hey, thanks for the concern guys.
    dealer confirmed that the shock is broke, and apparently also discontinued.
    so i am shopping around for a conventional shock to replace the ol' tennisball, which by the way lasted me about 107,000km...
