TIPAlthough the total number of clicks of a damping
force adjusting mechanism may not exactly match
the above specifications due to small differences
in production, the actual number of clicks always
represents the entire adjusting range. To obtain a
precise adjustment, it would be advisable to check
the number of clicks of each damping force adjust-
ing mechanism and to modify the specifications as
necessary.
WARNING
Suspension components become hot dur-
ing operation. Never touch the compres-
sion damping force adjusting screw, the
rebound damping force adjusting screw or
the oil reservoir with your bare hand or
skin until suspension components have
cooled.
Always adjust the shock absorber assem-
blies on the left and right side to the same
setting. Uneven adjustment can cause
poor handling and loss of stability, which
could lead to an accident.

Adjusting the rear shock absorber assemblies
The spring preload, rebound damping and com-
pression damping forces of the rear shock absorb-
er assemblies can be adjusted to suit the
operating conditions.
WARNING
These shock absorber assemblies contain
highly pressurized nitrogen gas. Read and un-
derstand the following information before han-
dling the shock absorber assemblies.
Do not tamper with or attempt to open the
cylinder assemblies.
Do not subject the shock absorber assem-
blies to an open flame or other high heat
source. This may cause the unit to explode
due to excessive gas pressure.
Do not deform or damage the cylinders in
any way. Cylinder damage will result in
poor damping performance.
Do not dispose of a damaged or worn out
shock absorber assembly yourself. Take
the shock absorber assembly to a Yamaha
dealer for any service.

1 -FOR YOUR SAFETY – PRE-OPERATION CHECKS
Inspect your vehicle each time you use it to make sure the vehicle is in safe operating condition. Always fol-
low the inspection and maintenance procedures and schedules described in the Owner’s Manual.
WARNING
Failure to inspect or maintain the vehicle properly increases the possibility of an accident or equip-
ment damage. Do not operate the vehicle if you find any problem. If a problem cannot be corrected
by the procedures provided in this manual, have the vehicle inspected by a Yamaha dealer.Before using this vehicle, check the following points:
ITEM ROUTINE PAGE
BrakesCheck operation, free play, fluid level, and fluid leakage.
Fill with DOT 4 brake fluid if necessary.5-7–5-9, 8-85–8-87,
8-91–8-95, 8-101
Parking brakeCheck for proper operation, condition, and free play. 8-89, 8-97–8-99
FuelCheck fuel level.
Fill with fuel if necessary.5-11–5-17
Engine oilCheck oil level.
Fill with oil to proper level if necessary.5-19, 8-25–8-37
Coolant reservoirCheck coolant level.
Fill with coolant if necessary.5-21, 8-53–8-55
Final gear oil/
Differential gear oilCheck for leakage. 5-23, 8-39–8-51

Fuel
Make sure there is sufficient gasoline in the tank.
WARNING
Gasoline and gasoline vapors are extremely flam-
mable. To avoid fires and explosions and to re-
duce the risk of injury when refueling, follow these
instructions.1. Before refueling, turn off the engine and be
sure that driver and passenger are outside
the vehicle.
Never refuel while smoking, or while in the vi-
cinity of sparks, open flames, or other sourc-
es of ignition such as the pilot lights of water
heaters and clothes dryers.
2. Do not overfill the fuel tank. Because fuel ex-
pands when it heats up, heat from the engine
or the sun can cause fuel to spill out of the
fuel tank.
3. Wipe up any spilled fuel immediately.
4. Be sure the fuel tank cap is closed securely.

WARNING
Gasoline is poisonous and can cause injury or
death. Handle gasoline with care. Never siphon
gasoline by mouth. If you should swallow some
gasoline or inhale a lot of gasoline vapor, or get
some gasoline in your eyes, see your doctor im-
mediately. If gasoline spills on your skin, wash with
soap and water. If gasoline spills on your clothing,
change your clothes.Your Yamaha engine has been designed to use
regular unleaded gasoline with a research octane
number of 91 or higher. If knocking or pinging oc-
curs, use a different brand of gasoline or premium
unleaded fuel. Unleaded fuel will give you longer
spark plug life and reduced maintenance cost.

Switches
Check the operation of all switches. Have a
Yamaha dealer repair as necessary for proper op-
eration.
Control cables
When riding in cold weather, always make sure all
control cables work smoothly before you begin
riding. WARNING! Control cables can freeze in
cold weather and you could be unable to con-
trol the vehicle.

Tire pressure
Use the tire pressure gauge to check and adjust
tire pressures when the tires are cold. Tire pres-
sures must be equal on both sides. WARNING!
Operation of this vehicle with improper tire
pressure may cause severe injury or death
from loss of control or rollover. Tire pressure
below the minimum specified could also cause
the tire to dislodge from the rim under severe
riding conditions.
Set tire pressures to the following specifications:ACE-02EThe tire pressure gauge is included as standard
equipment. Make two measurements of the tire
pressure and use the second reading. Dust or dirt
in the gauge could cause the first reading to be in-
correct.
