    I would suspect that the belt is not routed exactly right. Make sure it doesn't have a twist in it either.

    I had that same problem with a Z rider a few years ago. Never did figure it out. Its the belt shaking or wobbling. It was the worst with a high dollar kevlar belt.

    Sounds like a pulley is out of balance.........................
    not on the shaft correctly etc.

    That, and check all your idlers and also make sure they're holding the tension properly.
