Tech help: Chain adjusting 750 Kawasaki

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
alignment.

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

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.
