    Elmer,

    Do you think DynaBeads would help a situation like I have even though the tires were balanced when putting them on?

    Cheers,
    Greg

    Si, si Amigo...IT MIGHT..our rigs all wobble a bit at walking speed, but when speed picks up it should disappear.

    Now you of course must have everything on the bike that is related to rolling in good working order! A good tire; normal good shocks and no ridiculous play in the steering head.

    Static balancing or speed spin balancing is an imperfect science. Once mud; rocks..hitting a pothole, stick-on-weigh fell off, etc.. can and will throw the balancing off...Dynabeads will come to your rescue, balancing your tires on the fly when you roll and makes corrections when rolling. Try it..you'll like it...:eek1:evil.

    Wait...what??? 50,000 miles on your front tire?? :eek1:eek1:eek1 Which tire are you using??? I went back through the thread but missed what tire you are using.

    I believe that I do have everything in good working order. Spent days fine tuning the toe in, lean out and sidecar leveling to get it level under load and tracking straight with very little effort on the bars. I'm finally happy with the ride with and without monkey. So I believe that's all sorted.

    Pretty sure also that the steering head is A-OK, after all this is a fairly new rig with only about 7K on it. Tires all around are almost new, even the car tire pusher and hack tire. Wore out the front Tourance so it's been replaced with the new ME880.

    You're right in that it wobbles a bit a slow speed and then disappears about 20mph and above, after that it's very smooth going. It's just that the new ME880 accentuates the wobble by a factor of 3 or more. Perhaps the DynaBeads would help with that, I'm not sure. But I'm willing to give them a try. :)

    That ME880 is a hard, round tire and it takes a couple of thousand miles for mine to start wearing in enough for the wobble to start going away. That is the only downside to the ME880 that I have seen and personally I like the rounder tire on the front because it makes the steering easier.

    Thanks Dana, that helps. If it kept this up, it would be my first and only ME880. I was hoping that's all it was.

    Mine actually start getting squared off around 8 or 9 thousand miles. I haven't done any steering mods on mine either but I really don't mind the low speed wobble.

    You might run a little less pressure in the front too.

    Are you using the 110/90-19 or the 100/90-90 ME880? The 100/90-19 would be more rounded wouldn't it??

    Copy that.

    The 110/90 is just a wee bit wider than the 100/90, which esp. once worn slightly, should give a slightly larger patch on the ground.

    He, he..I meant the Dynabeads....they've been transferred (re-used) from tire to tire...:D

    Do you use them in the car tires on your hack and pusher tires as well? Or just in the front tire?

    I would guess that those who would use the beads would use them in everything and prolly use them to sweeten their cornflakes too!

    Used DynaBeads in all my previous moto tires, two wheeled then three wheeled. When traveling and having to change tires on the road...balancing them was an issue thus DynaBeads!

    Transfering/re-using the DynaBeads to new tires is indeed an Adventure :eek1...don't want to be Adventurous then carry extra tubes of "new" DynaBeads> $$$:evil.

    When I changed to car tires used it only in the front moto tire(Tourance) ....where the problem usually lies. Have no need to use them in the car tires yet.

    Put the ME 880 110/90H19 on my front about 1K miles ago.
    Have not seen any significant signs of wear yet.
    Low speed wobble is present only when I don't have ballast in the car.
    And the wobble is bad but manageable.
    One more reason to have a passenger...or at least a bag of cement.

    I haven't used Dana Beads in my tires.
    I use Ride-On.
    Won't balance on the fly like the beads and a bit more messy when changing a tire.
    But after suffering a blowout at 70+mph, I will deal with the mess.
    Cheers.

    I used Air Soft pellets one time on my old GS. They were cheap & they worked, but man, they were everywhere when tire change time came around. When I popped the bead, I used a small hand vacuum to suck the ones that weren't all over the floor out of the tire. Only did it once.

    I wouldn't recommend running lower pressure as a way to try to get rid of a low-speed wobble.
    Running lower pressure will seriously affect treadwear, and not for the better.

    Here is what my Front ME880 looked like after about 5,500 miles when I got home from the Lake Tahoe Sidecar National rally. It was put onto the rig brand new the week before leaving for the rally.
    Of course, that is also without steering mods on a "slightly" heavier outfit than Dana's, and after crossing the desert and having a bit of fun in more than a couple of mountain passes...

    [​IMG]

    Yes, that is the inner carcass rubber showing through in the center of the tread area. Not very many miles away from showing cords...

    So if you are getting the kind of mileage that you are reporting, you should be very happy.

    I have been using balancing beads inside of the tires on all of my vehicles for years, and yes doubting thomas's they DO work.
    (Ask the mechanical engineer who has seen dynamic balancing media used in rotating machinery for many-many years...)

    When traveling all you really need to do is bring along a paper cup, one of those folding paper funnels, and a couple of feet of 1/4" I.D. tubing.

    When you change the tire (like I just did earlier this week to install the summer front tire) remove the first bead and then use a small paper or plastic cup to scoop out the beads. You could even use one of the folding paper funnels with the bottom folded over to close it off...
    You can then use the paper funnel to transfer the beads into the tubing (make sure you have the bottom end plugged with a piece of dowel rod or something first, or they will just pour out the bottom!).
    Then you remove the valve core from the tire after reseating the tire to the rim and slip the tubing onto the valve stem to pour the beads back into the tire.

    Simple really!

    -----

    When I get my pusher and sidecar tire changed at the local tire shops they are familiar with "dynabeads" and have no problem with scooping them out of the old tire and pouring them into the new one before they remount it. Usually with no extra charge.

    If your have tubes in your tires, no problem. The tube contains the beads.
    And in case of a blow-out which scatters your beads, I carry an extra three ounces in a small pill bottle with the rest of my spares. Takes up almost no space and the pill bottle is waterproof and has a childproof cap so it won't accidently open and spill beads everywhere.

    -----

    btw - I used to recommend the "dynabeads" brand, but after some time (and interactions with the company) discovered that the owner of that business basically ripped off the idea from the place he used to work for and started out on his own with a slightly different (but not better) product.

    The original product in the market for this application is "CounterAct"
    {They hold a patent and guarantee they won't damage your tire pressure monitoring system. Ask dynabeads for that guarantee...}
    http://www.tirebalancingbeads.com/motorcycle-tire-wheel-balancing/

    The CounterAct beads hold a static charge so that they "stick" lightly to the inside of the tire, even when it comes to a complete stop. Therefore you don't need to wait for the wheel to come up to speed for the beads to redistribute each time you stop/start. That is a bonus for low-speed balance from a stop.

    And CounterAct bead kits come with an applicator bottle that would be easy to pack along on a hack for transfer of the beads for en-route tire changes/service.

    Also, CounterAct even offers a 'Trike' kit, which would be perfect for someone with a rig, especially if you have car tires on the pusher and sidecar, since they generally require the extra ounce of weight (3oz.).

    -----

    Anyway, that is my experience/opinion. YMMV.

    I figure since the plate on the rear of my GS says the tire pressure should be between 2.2 Bar (31 psi) and 2.9 Bar (42 psi) depending on loading and tire type and the ME880 Marathon on the front says "do not exceed 42 psi cold" on the sidewall then I should have a fair bit of room to experiment with. I generally run at 42 psi since as I said it turns a bit easier but I do get a little more headshake at around 20 mph while decelerating. If I drop the pressure down to 36 psi the headshake pretty much goes away but slow speed steering is a little harder. At the higher pressure, 42 psi, I changed the 110/90 - 19 ME880 Marathon out at around 14,000. I was getting around 8,000 miles out of the stock Tourance on the front but I probably do a lot more dirt riding with mine than you do also. Interstate speed limits are 75 out here with a few places that are 80 and I have no problem getting the chair up in the canyons in Utah and Arizona at 75 on the Interstate.
