9. Refill with the specified amount of the recommended engine oil.
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. Check the O-ring for damage, and replace it if necessary. 11. Install and tighten the engine oil fill-
er cap.
12. 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

off and have a Yamaha dealer check
the vehicle.
13. Turn the engine off, wait a few min- utes until the oil settles, and then
check the oil level and correct it if
necessary.
EAU20071
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 level1. 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.

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 effectiveness of the coolant will
be reduced.
[ECA10473]
EAU76810
To change the coolant1. Place the vehicle on a level sur- face and let the engine cool if nec-
essary.
2. Remove panel B. (See page 7-9.)
3. Place a container under the engine to collect the used coolant.
4. 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.

7. Drain the coolant from the coolant
reservoir by turning it upside down. 8. Install the coolant reservoir and its
cover by placing them in the origi-
nal position, and then installing the
collars and bolts.
9. Remove the coolant drain bolt and its gasket to drain the coolant from
the cooling system.
10. After the coolant is completely drained, thoroughly flush the cool-
ing system with clean tap water.
11. Install the coolant drain bolt and its new gasket, and then tighten the
bolt to the specified torque. 12. Pour the specified amount of the
recommended coolant into the ra-
diator and reservoir.
13. Install the coolant reservoir cap.
14. Install the radiator cap.
15. Start the engine, let it idle for sev- eral minutes, and then turn it off.
16. 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.
17. Check the coolant level in the res- ervoir. If necessary, remove the

dealer adjust it.
EAU21402
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

Changing the brake fluidHave a Yamaha dealer change the
brake fluid at the intervals specified in
the periodic maintenance and lubrica-
tion chart. In addition, have the oil seals
of the master cylinders and calipers as
well as the brake hoses replaced at the
intervals listed below or whenever they
are damaged or leaking.
Oil seals: Replace every two
years.

Brake hoses: Replace every four
years.

Drive chain slackThe drive chain slack should be
checked before each ride and adjusted
if necessary.
EAU2277G
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.
