    Dyna Beads

    Have installed balance beads in both tires. Balance seems good. Happy.
    However, when checking air pressure bead will get stuck in valve and then valve has to be romoved to get bead out. Happens only in rear tire. Annoying.

    Anybody else experience this? Fix ?

    Anybody running tubeless on snowflake rims? Mine are on 1982 R100RS.

    It happens to some folks frequently. The fix is to balance your tires another way.

    I use regular weights and haven't had one get stuck in the valve yet.

    Never have had this problem and have used Dyna Beads for 2 years now. Does it depend on the position of the valve stem (12 o'clock, 3 o'clock, 6 o'clock, etc) when the pressure is checked? The valve stem is bwt 3 o'clock and 9 o'clock when I check pressure. Would this make a difference?

    There was a huge discussion on Dyna Beads earlier at:

    http://www.bmwmoa.org/forum/showthread.php?t=53188&

    Since it's not really Airhead specific, I'm going to move this to the Gear forum where the other thread ran.

    I allways check with the valve stem at 6:00 and tap the valve stem first, never had a problem.

    It does happen, that's the point.

    Not on an Airhead, but I check pressure with the valve stem at 3 or 9. The beads will be at the bottom of the tire. If I had a bead get stuck in the valve, I'd try giving it a shot of air to push it back into the tire?

    I check pressure with the valve at the bottom. I figure that gives the best chance of the beads falling out *if* any happened to be in the stem. I've never had a problem with the beads clogging the stem with over 4 years of using beads for balance on tubed and tubeless tires. YMMV.

    Thump:)

    Seems a good thump of the tire would take care of most issues, before checking pressure. An odd thing, having them get stuck indeed. Most seem to not have an issue, but certainly some do. Just kicking the tire a few times or even once would perhaps clear the valve of beads as you check. Great suggestion. Randy

    If one does get stuck, you better have a pump and valve tool with you. It sez so right here:

    Appreciate the replies. Have tried having stem at different positions. Will try thumping. Valve stem tool and pump always with bike, however it is a pain.

    DITTO! Never been a problem & If you are checking the air it only makes sense to have more air on hand in the 1st place so give em a shot of air 1st then check.
