2. Check slack in the lower drive chain run midway
between the sprockets. Drive chain slack should
be adjusted to allow the following vertical
movement by hand:
20 – 30 mm (0.8 – 1.2 in)
3. Roll the motorcycle forward. Stop. Check the drive
chain slack. Repeat this procedure several times.
Drive chain slack should remain constant. If the
chain is slack only in certain sections, some links
are kinked and binding. Binding and kinking can
frequently be eliminated by lubrication.
NOTICE
Excessive chain slack may allow the drive chain to
damage the engine cases.

4. Roll the motorcycle forward. Stop and place
it on its side stand. Inspect the drive chain and
sprockets for any of the following conditions:
DRIVE CHAIN
* Damaged rollers
* Loose pins
* Dry or rusted links
* Kinked or binding links
* Excessive wear
* Improper adjustment
* Damaged or missing o-rings
SPROCKETS
* Excessively Worn Teeth
* Broken or Damaged Teeth
A drive chain with damaged rollers, loose pins,
or missing O-rings must be replaced. A chain
which appears dry, or shows signs of rust, requires
supplementary lubrication. Kinked or binding links
should be thoroughly lubricated and worked free. If
links cannot be freed, the chain must be replaced.
