Drive Chain
Refer to
Safety Precautions
on page 25.
An endless (riveted master link) chain connects
the drive and driven sprockets. The O-ring chain
uses rubber between the side plates of the pin and
roller links to seal in the manufacturer-installed
lubricating grease and keep out moisture and dirt.
The service life of the chain depends on proper
lubrication and adjustment. Poor maintenance
can cause premature wear or damage to the drive
chain or sprockets.
Under severe usage, or when the motorcycle is
ridden in unusually dusty or muddy areas, more
frequent maintenance will be necessary.
Before servicing your drive chain, turn the engine
OFF, raise the rear wheel off the ground by
placing the optional workstand or equivalent
support under the engine and check that your
transmission is in neutral.
It is not necessary to remove or replace the drive
chain to perform the recommended service in the
Regular off-road Use Maintenance Schedule
(page 27).
Inspection
1. Stop the engine and raise the rear wheel off
the ground by placing the optional workstand
or equivalent support under the engine and
shift the transmission into neutral.
2. Check slack (1) in the upper drive chain run
midway between the sprockets (2) (3). Drive
chain slack should allow the following vertical
movement by hand:
1 – 1 3/8 in (25 – 35 mm)
Excessive chain slack may allow the drive chain
to damage the engine cases.
(1) drive chain slack
(3) driven sprocket
(2) drive sprocket
If the chain is found to be slack in one segment
of its length and taut in another, this indicates
that some of the links are either worn, kinked or
binding. Kinking and binding can frequently be
eliminated by thorough cleaning and lubrication.
If the drive chain requires adjustment, procedure
is as follows:
NOTICE
Adjustment
1. Loosen the rear axle nut (1).
2. Loosen the lock nuts (2) and turn the
adjusting bolts (3) counterclockwise to
decreace slack or clockwise to increase slack.
Align the index mark (4) on both sides of the
swingarm with same reference marks (5) of
the plates.
(1) rear axle nut
(4) index mark
(2) lock nut
(5) reference mark
(3) adjusting bolt
3. Tighten the rear axle nut to the specified
torque:
94 lbf·ft (128 N·m, 13.1 kgf·m)
4. Recheck chain slack and adjust if necessary.
5. Turn the adjusting bolts counterclockwise
lightly until it touches the axle plate. Then,
tighten the lock nuts to the specified torque by
holding the adjusting bolts with a wrench.
20 lbf·ft (27 N·m, 2.8 kgf·m)
