    Chain was loose, so tried to tighten it, put new adjusting bolts
    in .While moving tire the chain seems to not ride in sprocket in one
    area kind of binds a bit, is this caused by a miss adjustment on one
    side? Looks like wheel is turning perfect when turning on center
    stand? Thanks for any help. Terry

    Sounds like one of your links is binding or you may need a new
    sprocket(s). Have you checked the sprockets to see if they are worn? You
    may also have tightened it a bit too much. It should have a little play in
    it. Check your manual for the proper amount.

    Hope this helps...

    If the chain adjuster alignment marks are incorrect (or gone) on your
    swingarm, then you will need to measure on each side of the swingarm,
    from the middle of the swingarm pivot shaft to the center of the rear
    axle. These measurements should be identical for proper chain

    Here is a tool that works well, if you have a good "eye" for such

    It's what I use on my dirt bikes.

    Most likely the chain and sprockets are worn out. Look carefully at the
    sprockets. If the teeth seem slanted at all, they're worn out. If the
    sprockets are worn out, the chain also must go.

    If your wheel isn't straight in the swing arm, you'll see that the
    sprockets are shiny from wear on the sides of the teeth.

    If you look down in between the chain's inner link plates, you'll see
    that they are worn shiny from misalignment.

    The hardened steel pins inside the links and the softer bushing are
    what wears in a chain and makes the chain seem to have "stretched".

    The pins and bushings don't wear evenly, some wear out quicker than
    others, so you wind up with tight places and loose places in the chain
    even after you've adjusted it.

    And, once the rubber o-rings have stopped sealing the grease inside
    the chain, some links will bind up and make the chain look a little
    zig-zaggy in the bottom run.

    The binding links will not follow the small drive sprocket and they
    will make a clunky noise.

    Trying to straighten out binding links doesn't work, there is no
    lubricant inside the pins any more, just dirt.

    Time for a new chain.
