ACCESSORIES AND LOADING
Adding accessories or cargo to your machine can adversely affect stability and handling if the weight distribution of the machine
is changed. To avoid the possibility of an accident, extreme caution should be used if adding cargo or accessories to your
machine.
Use extra care if riding a machine which has added cargo or acessories. Genuine Yamaha accessories have been specifically
designed for use on this machine. Since Yamaha cannot test all other accessories which may be available, you must personally
be responsible for the proper selection, installation and use of non-Yamaha accessories.
You should use extreme caution when selecting and installing any accessories. Keep in mind these guidelines for mounting
accessories in addition to those provided under “LOADING”.
1. Never install accessories or carry cargo that would impair the performance of your machine. Carefully inspect the accessory
before using it to make sure it does not in any way reduce ground clearance or cornering clearance, limit suspension travel,
steering travel or control operation, or obscure lights or reflectors.
a. Accessories fitted to the handlebar or the front fork area can create instability due to improper weight distribution or aerodynamic
changes. If accessories are added to the handlebar or front fork area, they must be as lightweight as possible and should be kept
to a minimum.
b. Bulky or large accessories may seriously affect the stability of the machine due to aerodynamic effects. Wind may attempt
to lift the machine, or the machine may become unstable in cross winds. These accessories may also cause instability when
being passed by or passing large vehicles.
c. Certain accessories can displace the operator from his or her normal riding position. This improper position limits the
freedom of movement of the operator and may limit control ability. Therefore such accessories are not recommended.
2. Caution must be used if adding electrical accessories. If these accessories exceed the capacity of the machine’s electrical
system, an electric failure could result, which could cause a dangerous loss of lights or engine power.

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

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.
