How can I prevent highway peg U-bolt from spinning on my crash bar?

    I'm trying to install a set of Adventure Designs highway pegs on Tiger 800 OEM crash bars. I tightened them to the point that it appears I've put a small dent in bars but I can still spin them with just a small amount of pressure. I don't have the balls to tighten them any further.

    In the past I've drilled a hole and put in a screw or even used Gorilla Glue. I really can't do that with this set.

    Help?

    Thanks!

    Use a strip of rubber around the bar as a shim?

    I tried that with a piece of heavy duty rubber hose, the bolt bit right through. Friction tape seemed to help it spin easier.

    With that U-bolt type mount I wonder if you have to get a cheater bar and just keep cranking? I'm stumped so I'll just hush now. We'll wait to see what some of the other folks suggest.

    Thanks. Since it looks like I've already put a dent in the bars I'm worried about the bolt cutting in.

    If it was my buddies bike I'd have no problem with the keep cranking method :lol3

    Maybe you can line the U-bolt with a strip of metal to spread the clamping force over a larger surface area? Something in the neighborhood of 16ga, might be able to find something in the plumbing or elec. dept of your hardware store.
    Too bad your crashbars don't have a short section of square tube to clamp to. :hmmmmm Got any pictures?
    Might also be able to make your own clamp blocks along the lines of handlebar mounts.

    I had this same problem. I cut a strip of sandpaper, doubled it over so there is abrasive on both sides and clamped it in. Voila!! No more slippy! :clap

    Thanks folks. I moved the pegs to my second choice location and it's looking like it's going to work.

    Careful not to over tighten the U bolts on the frame. You can damage the frame, cause a bend and/or a weak spot.

    Cut up beer cans make excellent shim material.

    Take a look at some of these accessory pegs. The bolts have a pair of spacers with a conical edge. The conical spacers help tighten the wrap of the clamp on the tubing. If the tubing isn't the right size to make the little spacers work well, see if a few washers under the spacers will help?

    Also, try wrapping the tube or lining the clamp with some self-adhering grit strips like one would use on wooden steps/treads to prevent slipping when they are wet? The strips are cheap and if you tear one up in a get-off, it is easy to add another wrap.

    Emory cloth works very well for this stuff but a good clamp is just a little out of round vs a u-bolt. It wont spin and it wont mark or dent your bars.

    Maybe put them where you want them and then braze them in place?

    The nice thing about brazing is that you can un-do it fairly easily.

    I'd ditch the U-bolt and fabricate up some SS strap in a saddle clamp shape, and use a couple of bolts instead, or if your material is thin enough you can have the clamp run under the U-bolt. The trick is to have it mechanically attached to your foot pegs. Originally I was thinking about welding pads to your u-bolts but I like this approach better.

    Made up brackets and fitted my TOP SECRET "Ranger Hi-Way pegs" after thinking that all of the bolt-on pegs were junk. These work fantastically and can easily be clicked in, or out with your feet.
    (Let's see how long it is before these get copied.....:evil)

    Here they are "closed"
    [​IMG]

    And here they are "out for use" and super comfy :clap

    You can also see that i've drilled and countersunk the Weld 86 bashplate for some more ventilation to the VR

    These pegs are so much better than any generic bolt-on pegs that i found during my research.

    A lot of people comment on them when i'm out and about.

    I call them my "Ranger Pegs"

    Drill a hole and hammer in a roll pin. I hate anything kuryikan the chrome doesn't last as long as the plastic packaging

    I also like this simple yet very effective engineering solution :clap

    All of the other "fixes" are just handyman type solutions, which although solving a problem, don't do your bike the justice that it deserves. (and they look like crap too!)

    Just sayin.......

    if they spin that easily- it sounds like the Ubolt is too large, and not contacing enough ot the frame/crashbar tube . . . .

    get/make a smaller ubolt, or use something similar to the Kuryakyn dealio . . . .
