NOTICE
ECA10402
If the oil level warnin g li ght flickers
or remains on even if the oil level is
correct, immed iately turn the en gine
off an d have a Yamaha d ealer check
the vehicle.
11. Turn the engine off, wait a few mi- nutes until the oil settles, and then
check the oil level and correct it if
necessary.
12. Install the cowling.
EAU20071
Coolant
The 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.
EAU46804To check the coolant level 1. Place the vehicle on a level surfa- ce 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 tem-
perature.
Make sure that the vehicle is posi-
tioned straight up when checking
the coolant level. A slight tilt to the
side can result in a false reading.
2. Check the coolant level in the
coolant reservoir.
TIP
The coolant should be between the mi-
nimum and maximum level marks.

3. If the coolant is at or below the mi-
nimum level mark, remove the
coolant reservoir breather hose
from the guide, and then remove
the coolant reservoir cap.
WARNING! Remove only the
coolant reservoir cap. Never at-
tempt to remove the ra diator
cap when the en gine is hot.
[EWA15162]
4. Add coolant to the maximum level
mark, and then install the coolant
reservoir cap. NOTICE: If coolant
is not availab le, use distille d wa-
ter or soft tap water instea d. Do
not use har d water or salt water
since it is harmful to the en gine.
If water has been used instead
of coolant, replace it with cool-
ant as soon as possi ble, other-
wise the coolin g system will not
b e protecte d a gainst frost an d
corrosion. If water has b een
a dde d to the coolant, have a
Yamaha dealer check the anti-
freeze content of the coolant as
soon as possi ble, otherwise the
effectiveness of the coolant will
b e red uced.
[ECA10473]
5. Route the coolant reservoir
breather hose through the guide
as shown.
EAU46824To chan ge the coolant
1. Place the vehicle on a level surfa- ce and let the engine cool if neces-
sary.
2. Remove cowling A and panel B. (See page 6-7.)
3. Place a container under the en- gine to collect the used coolant.
4. Remove the radiator cap retaining bolt, radiator cap retainer and ra-
diator cap. WARNING! Never at-
tempt to remove the ra diator
cap when the en gine is hot.

bolts.
12. Pour the specified amount of the recommended coolant into the ra-
diator and reservoir.
13. Install the radiator cap.
14. Install the coolant reservoir 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 radi-
ator, and then install the radiator
cap, radiator cap retainer and ra-
diator cap retaining bolt. 17. 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.
18. Route the coolant reservoir breather hose through the guide
as shown.
19. Start the engine, and then check the vehicle for coolant leakage. If
coolant is leaking, have a Yamaha
dealer check the cooling system.
20. Install the cowling and the panel.

Replacin g the air filter ele-
ment
The air filter element should be re-
placed at the intervals specified in the
periodic maintenance and lubrication
chart. Replace the air filter element
more frequently if you are riding in un-
usually wet or dusty areas.
1. Remove the seat. (See page 3-18.)
2. Remove the fuel tank bolts, and then lift the fuel tank away from
the air filter case.
3. Remove the air filter case cover by removing the screws. NOTICE:
When removin g the air filter
case cover, be careful not to al-
low forei gn o bjects to d rop into
the air intake manifol d.
[ECA12882]
4. Pull the air filter element out. 5. Insert a new air filter element into
the air filter case. NOTICE: Make
sure that the air filter element is
properly seated in the air filter
case. The en gine shoul d never
b e operated without the air filter
element installed , otherwise the
piston(s) an d/or cylin der(s) may
b ecome excessively worn.
[ECA10482]
6. Install the air filter case cover by
installing the screws.
7. Place the fuel tank in its original position. Make sure that the fuel
hoses are properly connected and
routed, and are not pinched. Be
sure to place the hoses in their
original position. WARNING! Be-
fore placin g the fuel tank in the
ori ginal position, make sure that
all hoses (i.e., fuel hose, fuel
tank breather hose, fuel tank
overflow hose) are not d am-
a g ed , that they are properly
connected and route d, an d that
they are not pinche d. If any hose
is damag ed , have a Yamaha

The engine idling speed must be
checked and, if necessary, adjusted as
follows at the intervals specified in the
periodic maintenance and lubrication
chart.
The engine should be warm before
making this adjustment.
Check the engine idling speed and, if
necessary, adjust it to specification by
turning the idle adjusting screw. To in-
crease the engine idling speed, turn the
screw in direction (a). To decrease the
engine idling speed, turn the screw in
direction (b).

Tires
Tires 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 d eath from loss of
control. The tire air pressure must be
checked and a djuste d on col d
tires (i.e., when the temperature
of the tires equals the am bient
temperature).
The tire air pressure must be
a d juste d in accor dance with the
ri din g speed and with the total
wei ght of ri der, passen ger, car-
g o, an d accessories approve d
for this mo del.WARNING
EWA10512
Never overloa d your vehicle. Opera-
tion of an overloa ded vehicle coul d
cause an acci dent.
Tire inspection
The tires must be checked before each
ride. If the center tread depth reaches
the specified limit, if the tire has a nail
or glass fragments in it, or if the side-
wall is cracked, have a Yamaha dealer
replace the tire immediately.
