Too little chain slack will overload
the engine and other vital parts.
Keep the slack within the specified
limits.

EAU01106*Drive chain lubrication
The chain consists of many parts
which work with each other. If the
chain is not maintained properly, it
will wear out quickly. Therefore,
the chain must be serviced regular-
ly. This service is especially neces-
sary when riding in dusty areas.
The drive chain should be lubri-
cated every 500 km. First, remove
all dirt and mud from the chain
with a brush or cloth. Then, spray
any of the many brands of spray-
type chain lubricant between
both rows of side plates and on
all center rollers.
To clean the chain thoroughly,
remove it from the motorcycle,
dip it in solvent, and clean out as
much dirt as possible. Then, take
the chain out of the solvent to
dry it, and immediately lubricate
it to prevent it from rusting.
EC000097
cC
Be sure to oil the chain after wash-
ing the motorcycle or riding in the
rain.
Tightening torque:
Wheel axle nut:
90 Nm (9.0 m·kg)

EAU01497Rear wheel installation
1. Install the wheel assembly and
insert the axle from the left-
hand side. Be sure that the
chain adjusting plates are
installed with the punched side
outward and the slot in the
brake shoe plate fits over the
stopper on the swingarm.
2. Install and adjust the drive
chain. (See page 6-24 for
details about adjusting the
drive chain slack.)
3. Install the axle nut and let the
motorcycle down.4. Tighten the axle nut to the
specified torque.
5. Insert the brake rod into the
brake cam lever and install the

9 8Improper cleaning can damage
windshields, cowlings, panels
and other plastic parts. Use
only a soft, clean cloth or
sponge with mild detergent
and water to clean plastic.
8Do not use any harsh chemical
products on plastic parts. Be
sure to avoid using cloths or
sponges which have been in
contact with strong or abra-
sive cleaning products, solvent
or thinner, fuel (gasoline), rust
removers or inhibitors, brake
fluid, antifreeze or electrolyte.8Do not use high-pressure
washers or steam-jet cleaners
since they cause water seep-
age and deterioration in the
following areas: seals (of
wheel bearings, swingarm
bearings, forks and brakes),
electric components (couplers,
connectors, instruments,
switches and lights), breather
hoses and vents.
8For motorcycles equipped
with a windshield: Do not use
strong cleaners or hard
sponges as they will cause
dulling or scratching. Some
cleaning compounds for plas-
tic may leave scratches on the
windshield. Test the product
on a small hidden part of the
windshield to make sure they
do not leave any marks. If the
windshield is scratched, use a
quality plastic polishing com-
pound after washing.
After riding in the rain, near the
sea or on salt-sprayed roads
Since sea salt or salt sprayed on
the roads in the winter are
extremely corrosive in combina-
tion with water, carry out the fol-
lowing steps after each ride in the
rain, near the sea or on salt-
sprayed roads. (Salt sprayed in the
winter may remain on the roads
well into spring.)
1. Clean your motorcycle with
cold water and soap after the
engine has cooled down.
ECA00012
cC
Do not use warm water since it
increases the corrosive action of
the salt.
2. Be sure to apply a corrosion
protection spray on all (even
chrome- and nickel-plated)
metal surfaces to prevent cor-
rosion.
