6-26Cable inspection and lubrication 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 regularly.
This service is especially necessary when riding in dusty
areas.
1. Use Yamaha Chain and Cable Lube or any brands of
spray-type chain lubricant. First, remove all dirt and mud
from the chain with a brush or cloth, then spray lubricant
between both rows of side plates and on all center
rollers. The chain should be lubricated every 500 km
(300 mi).
2. To clean the chain, remove it from the machine, dip it
in solvent, and clean out as much dirt as possible. Take
the chain out of the solvent and dry it. Immediately
lubricate the chain to prevent it from rusting.Damage to the outer housing of cables may allow
internal rusting and cause interfere with cable
movement. Replace damaged cables as soon as
possible to prevent unsafe conditions.
Lubricate the inner cable and the cable end. If it does not
operate smoothly, ask a Yamaha dealer to replace them.
RECOMMENDED LUBRICANT:
Engine oil SAE 20W50

Lubricate the pivoting parts.
RECOMMENDED LUBRICANT:
Engine oil SAE 20W50 Throttle cable and grip lubrication
The throttle twist grip assembly should be greased at the
time the cable is lubricated, since the grip must be removed
to get at the end of the throttle cable.
After removing the screws, hold the end of the cable up in
the air and put in several drops of lubricant. With the throttle
grip disassembled, coat the metal surface of the grip
assembly with a suitable all-purpose grease.Brake and shift pedals

Front fork inspection
1. Visual check
Check for scratches or damage on the inner tube and
excessive oil leakage from the front fork.
2. Operation check Place the motorcycle on a level place.
a. Hold the motorcycle in an upright position and apply the front brake.
b. Push down hard several times and check if the fork rebounds smoothly.
If any damage or unsmooth movement is found with
the front fork, consult a Yamaha dealer.
CAUTION:
Securely support the motorcycle so there is no danger
of it falling over.

This shock absorber contains highly pressurized
nitrogen gas. Read and understand the following
information before handling the shock absorber. The
manufacturer cannot be held responsible for property
damage or personal injury that may result from improper
handling.
1. Do not tamper with or attempt to open the cylinderassembly.
2. Do not subject the shock absorber to an open flame or other high heat source. This may cause the unit
to explode due to excessive gas pressure.
3. Do not deform or damage the cylinder in any way. Cylinder damage will result in poor damping
performance.
4. Take your shock absorber to a Yamaha dealer for any service.
Rear shock absorber adjustment
The spring prelod of the rear shock absorber can be adjusted
to suit rider’s preference, weight and course condition.
Turn the adjusting ring in direction a to increase spring
preload and in direction b to decrease spring preload. Make
sure that the appropriate notch in the adjusting ring is aligned
with the position indicator on the rear shock absorber.

Wheel bearings
If there is play in the front or rear wheel hub or if the wheel
does not turn smoothly, have a Yamaha dealer inspect the
wheel bearings. The wheel bearings should be inspected
according to the Maintenance Schedule. Steering inspection
Securely support the motorcycle so there is no danger
of it falling over. Periodically inspect the condition of the steering. Worn out
or loose steering bearings may be dangerous. Place a stand
under the engine to raise the front wheel off the ground.
Hold the lower end of the front forks and try to move them
forward and backward. If any free play can be felt, ask a
Yamaha dealer to inspect and adjust the steering. Inspection
is easier if the front wheel is removed.

Battery
BATTERY BREATHER HOSE ROUTING
YAMAHA 5RM-F8179-00Check the level of the battery electrolyte and make sure
that the terminals are tight. Add distilled water if the
electrolyte level is low.
1. When inspecting the battery, make sure that the
battery breather pipe routing is correct. If the
breather pipe touches painted parts, or if its end is
in such a position that may cause gas or electrolyte
leakage, it may cause structural or esthetic damages
to the motorcycle.
2. Take care not to spill battery fluid on the chain.
Battery fluid may weaken the chain causing shorter
chain life and possibly result in an accident.

CAUTION:
Battery electrolyte is poisonous and dangerous,
causing severe burns, etc. It contains sulfuric acid.
Avoid contact with skin, eyes or clothing.
Antidote:
EXTERNAL: Flush with water.
INTERNAL: Drink large quantities of water or milk.
Follow with milk of magnesia, beaten egg, or vegetable
oil. Call a physician immediately.
EYES: Flush with water for 15 minutes and get prompt
medical attention.
Batteries produce explosive gases. Keep sparks, flame,
cigarrettes, etc., away. Ventilate when charging or using
it in an enclosed space. Always shield your eyes when
working near batteries.
KEEP OUT OF REACH OF CHILDREN.
Replenishing the battery fluid

 
Normal tap water contains minerals which are harmful
to a battery; therefore, refill only with “distilled water”.
A poorly maintained battery will corrode and discharge
quickly. The battery fluid should be checked at least once a
month.
The level should be between the minimum and maximum
marks. Use only “distilled water” if refilling is necessary.
