4. Turn the adjusting nut (3) on both the right
and left chain adjusters an equal number of
turns to increase or decrease chain slack.
Align the Notches (4) on the chain adjusters
with the graduated scales (5) on both sides
of the swingarm.
If the drive chain slack is excessive when the
rear axle is moved to the furthest limit of
adjustment, the drive chain is worn and must
be replaced.
5. Tighten the rear axle nut to:
62 N·m (6.3 kgf·m, 46 lbf·ft)
6. Tighten the adjusting nuts lightly, then
tighten the lock nuts by holding the
adjusting nuts with a spanner.
7. Recheck drive chain slack.
8. Rear brake pedal freeplay is affected when
repositioning the rear wheel to adjust drive
chain slack. Check rear brake pedal
freeplay and adjust as necessary (page 26).
If a torque wrench is not used for this
installation, see your dealer as soon as possible
to verify proper assembly.
Lubrication:
Lubricate every 500 km (300 miles) or sooner
if chain appears dry.

Drive chain lubricant
If not available, use SAE 80 or 90 gear oil.
Saturate each chain link joint so that the
lubricant penetrates between the link plates,
pins, bushings, and rollers.
