gasket to drain the oil from the
crankcase.
TIPSkip steps 5–7 if the oil filter cartridge isnot being replaced.
5. Remove the oil filter cartridge with an oil filter wrench.
TIPAn oil filter wrench is available at aYamaha dealer.
6. Apply a thin coat of clean engine oil to the O-ring of the new oil filter
cartridge.
TIPMake sure that the O-ring is properlyseated.
7. Install the new oil filter cartridge with an oil filter wrench, and then

9. Refill with the specified amount of the recommended engine oil, and
then install and tighten the oil filler
cap.
TIPBe sure to wipe off spilled oil on any
parts after the engine and exhaust sys-tem have cooled down.NOTICE


In order to prevent clutch slip-
page (since the engine oil also
lubricates the clutch), do not
mix any chemical additives. Do
not use oils with a diesel speci-
fication of “CD” or oils of a high-
er quality than specified. In
addition, do not use oils labeled
“ENERGY CONSERVING II” or
higher.

Make sure that no foreign mate-rial enters the crankcase.
10. Start the engine, and then let it idle for several minutes while checking it for oil leakage. If oil is leaking, im-
mediately turn the engine off and
check for the cause.
TIPAfter the engine is started, the engine
oil level warning light should go off if theoil level is sufficient.NOTICE
ECA10402
If the oil level warning light flickers
or remains on even if the oil level is
correct, immediately turn the engine
off and have a Yamaha dealer checkthe vehicle.
11. Turn the engine off, wait a few min- utes until the oil settles, and then
check the oil level and correct it if
necessary.

CoolantThe coolant level should be checked
before each ride. In addition, the cool-
ant must be changed at the intervals
specified in the periodic maintenance
and lubrication chart.
EAU20095
To check the coolant level 1. Place the vehicle on a level sur- face and hold it in an upright posi-
tion.TIP
The coolant level must be checked
on a cold engine since the level
varies with engine temperature.

Make sure that the vehicle is posi-
tioned straight up when checking
the coolant level. A slight tilt to theside can result in a false reading.
2. Check the coolant level in the cool- ant reservoir.
TIPThe coolant should be between theminimum and maximum level marks. 3. If the coolant is at or below the
minimum level mark, remove the
reservoir cap. WARNING! Re-
move only the coolant reservoir
cap. Never attempt to remove
the radiator cap when the en-
gine is hot.
[EWA15162]
4. Add coolant to the maximum level mark, and then install the reservoir
cap. NOTICE: If coolant is not
available, use distilled water or
soft tap water instead. Do not
use hard water or salt water
since it is harmful to the engine.
If water has been used instead
of coolant, replace it with cool-
ant as soon as possible, other-
wise the cooling system will not
be protected against frost and
corrosion. If water has been
added to the coolant, have a
Yamaha dealer check the anti-
freeze content of the coolant as
soon as possible, otherwise the

To change the coolant1. Place the vehicle on a level sur- face and let the engine cool if nec-
essary.
2. Place a container under the engine to collect the used coolant.
3. Remove the radiator cap retaining bolt, radiator cap retainer and radi-
ator cap. WARNING! Never at-
tempt to remove the radiator
cap when the engine is
hot.
[EWA10382]
4. Remove the coolant reservoir cov- er and coolant reservoir by remov-
ing the bolts and collars. 5. Remove the coolant reservoir cap.
6. Drain the coolant from the coolant
reservoir by turning it upside down.

7. Install the coolant reservoir and its
cover by placing them in the origi-
nal position, and then installing the
collars and bolts.
8. Remove the coolant drain bolt and its gasket to drain the coolant from
the cooling system.
9. After the coolant is completely drained, thoroughly flush the cool-
ing system with clean tap water.
10. Install the coolant drain bolt and its new gasket, and then tighten the
bolt to the specified torque. 11. Pour the specified amount of the
recommended coolant into the ra-
diator and reservoir.
12. Install the coolant reservoir cap.
13. Install the radiator cap.
14. Start the engine, let it idle for sev- eral minutes, and then turn it off.
15. Remove the radiator cap to check the coolant level in the radiator. If
necessary, add sufficient coolant
until it reaches the top of the radia-
tor, and then install the radiator
cap, radiator cap retainer and radi-
ator cap retaining bolt.
16. Check the coolant level in the res- ervoir. If necessary, remove the
coolant reservoir cap, add coolant to the maximum level mark, and
then install the cap.
17. Start the engine, and then check the vehicle for coolant leakage. If
coolant is leaking, have a Yamaha
dealer check the cooling system.

Valve clearanceThe valve clearance changes with use,
resulting in improper air-fuel mixture
and/or engine noise. To prevent this
from occurring, the valve clearance
must be adjusted by a Yamaha dealer
at the intervals specified in the periodic
maintenance and lubrication chart.
EAU64410
TiresTires are the only contact between the
vehicle and the road. Safety in all con-
ditions of riding depends on a relatively
small area of road contact. Therefore, it
is essential to maintain the tires in good
condition at all times and replace them
at the appropriate time with the speci-
fied tires.
Tire air pressure
The tire air pressure should be checked
and, if necessary, adjusted before each
ride.
WARNING
EWA10504
Operation of this vehicle with im-
proper tire pressure may cause se-
vere injury or death from loss of
control.
The tire air pressure must be
checked and adjusted on cold
tires (i.e., when the temperature
of the tires equals the ambient
temperature).

The tire air pressure must be ad-
justed in accordance with the
riding speed and with the total weight of rider, passenger, car-
go, and accessories approved
for this model.WARNING
EWA10512
Never overload your vehicle. Opera-
tion of an overloaded vehicle couldcause an accident.
Tire air pressure (measured on cold
tires):
1 person:Front: 250 kPa (2.50 kgf/cm
2, 36 psi)
Rear: 290 kPa (2.90 kgf/cm2, 42 psi)
2 persons:

Drive chain slackThe drive chain slack should be
checked before each ride and adjusted
if necessary.
EAU2277C
To check the drive chain slack 1. Place the motorcycle on the sides- tand.TIPWhen checking and adjusting the drive
chain slack, there should be no weighton the motorcycle.
2. Shift the transmission into the neu- tral position.
3. Measure the drive chain slack as shown. 4. If the drive chain slack is incorrect,
adjust it as follows. NOTICE: Im-
proper drive chain slack will
overload the engine as well as
other vital parts of the motorcy-
cle and can lead to chain slip-
page or breakage. If the drive
chain slack is more than 25.0
mm (0.98 in), the chain can dam-
age the frame, swingarm, and
other parts. To prevent this from
occurring, keep the drive chain
slack within the specified lim-
its.
[ECA17791]
EAU57971
To adjust the drive chain slack
Consult a Yamaha dealer before ad-justing the drive chain slack.
1. Loosen the axle nut and the lock- nut on each side of the swingarm.
2. To tighten the drive chain, turn the drive chain slack adjusting bolt on
each side of the swingarm in direc-
tion (a). To loosen the drive chain,
turn the adjusting bolt on each side
of the swingarm in direction (b),
and then push the rear wheel for-
ward.
