the sprocket, resulting in an accident or serious
damage to the motorcycle. Inspect and adjust the drive
chain slack before each use.

malconditions. (Lift the rear wheel by placing the center stand,
and turn the rear wheel slowly by hand with transmission in
NEUTRAL.)
1. Loose pins
2. Damage rollers
3. Rusted links
4. Twisted or seized links
5. Excessive wear
If any defects are found, the drive chain must be replaced.
Damage to the drive chain means that the sprockets may also
be damaged. Inspect the sprockets for the following:
1.Excessively worn teeth
2.Broken or damaged teeth

After throughly washing the drive chain with detergent liquid
and allowing it to dry, lubricate the drive chain with chain lube
or new engine oil.

between. If the distance exceeds 259.4 mm, the chain must be
replaced.
