Count out 21 pins (20-pitch) on the drive chain and measure
the distance between the two points. If the distance exceeds
the service limit, replace the drive chain with a new one.
09900-20103: Vernier calipers
Drive chain 20-pitch length
Service Limit: 319.4 mm (12.57 in)
Place the motorcycle on the side stand.
Loosen or tighten both chain adjusters 1 until there is 40 –
50 mm (1.6 – 2.0 in) of slack at the middle of the chain be-
tween the engine and rear sprockets as shown. The refer-
ence marks 2 on both sides of the swingarm and the edge of
each chain adjuster must be aligned to ensure that the front
and rear wheels are correctly aligned.
Drive chain slack: 40 – 50 mm (1.6 – 2.0 in)
After adjusting the drive chain, tighten the rear axle nut 3 to
the specified torque.
Rear axle nut:
100 N·m (10.0 kgf-m, 72.5 lb-ft) .. For E-03, 28, 33
110 N·m (11.0 kgf-m, 79.5 lb-ft) .. For the other countries
CLEANING AND LUBRICATING
Clean the drive chain with kerosine. If the drive chain tends to
rust quickly, the intervals must be shortened.
Do not use trichlene, gasoline or any similar fluids.
These fluids have too great a dissolving power for this
chain and, what is more important, they can damage
the O-rings (or seals) confining the grease in the bush-
ing to pin clearance. Remember, high durability comes
from the presence of grease in that clearance.
After cleaning and drying the chain, oil it with a heavyweight
engine oil.
