    So...

    When I get the bike up around 70MPH I have a bit of high speed wobble nothing major but it is annoying. I don't have a steering damper on the bike at the moment and am not sure if I am going to put one on this bike yet...

    So what can I do to cure the wobble???

    change your triple clamp offset from 24mm to 22mm to increase trail.

    If someone could post pictures of the additional supports, we all could benefit from KTM's substantial R&D investment.

    1. Is it consistently the same on different types of pavement?
    2. Check tire/ air pressure/ balance
    3. Check suspension/ forks
    Wobble worries me because if it's happening on say smooth asphalt a bit more kinetics (such as rock, rut, etc) could set off the nasty harmonic known as "Freakin' Death Wobble"! :eek1 aka. headshake. And I hate it when that happens. Especially at 70mph.

    Sometimes simply squeezing the 'tank' with your knees keeps a bike 'tight' and reduces/eliminates shimmies/wobbles.
    Thats worked for me on many bikes over the years.

    1, Yes.
    2, Happens at different air pressures (22, 28, 32)
    3, Suspension is about to be sent out for revalving, reshimming, respringing for my MASS and my camping load.

    Worries me also...

    Squeezing the tank will get rid of it as well as tensing up on the handgrips.

    Isnt the wobble just the joy of having knobby tires?
    My GS wobbled too with knobbies on pavement.
    The steering damper helped.
    You can ride my bike and see if the damper helps you and if you want to invest in one.

    Re wobble at 70: Check the alignment of your front and back tires and check that the distance from swingarm pivot to axle center is the same on both sides. I did up to 80 on pavement using Michelin Desert tires which have aggressive knobs not good for the street and no wobble. Stock(steeper) steering head angle.

    Technical responce from my ktm mechanic about the speed wobble was "yeah they do that" - full fuel with extra luggage plus a damper turned up gets rid of it remember to turn damper down in dirt tho found that out the hard way

    Most shops are giving out a free donut, some (Dunkin') with purchase of a drink.

    This came in the mail from ca cycleworks. I had one sitting on the shelf forever and after a few stalls, a bunch of black junk in the filter and 6k miles it was time to go in. I could not figure out how to attach the 32$ 1 foot length of submersible hose to the pump outlet so i called the company and the nice lady sent a new style replacement with the barbed fitting, but no sock filter so i guess the stock screen fits. Seems like it all should stay together,crossing my fingers

    Just curious how prevalent the fuel pump failures are these days. My original failed at around 12K miles about 2 years ago, the current one has 13K on it now. Not sure if it was a different model then the original, but the housing was a different color. As mentioned before the brush wiring breaking from vibration was the reason for the failure, so I wonder if the later pumps addressed the brittle wire issue.
