Oil level warning light “ ”
This warning light comes on when the
key is in the “ ” position or if the oil
level in the 2-stroke engine oil tank is
low during operation. If the warning
light comes on during operation, stop
immediately and fill the oil tank with
2-stroke engine oil of either JASO
grade “FC” or ISO grades “EG-C” or
“EG-D”. The warning light should go
off after the 2-stroke engine oil tank
has been refilled.

Coolant temperature warning light
“”
This warning light comes on if the
engine overheats. If this occurs, stop
the engine immediately and allow the
engine to cool.
The electrical circuit of the warning
light can be checked by turning the
key to “ ”. The warning light should
come on for a few seconds, and then
go off.
If the warning light does not come
on initially when the key is turned to
“ ”, or if the warning light remains
on, have a Yamaha dealer check the
electrical circuit.
ECA10021
Do not continue to operate the
engine if it is overheating.
TIP
For radiator-fan-equipped vehi-
cles, the radiator fan(s) automati-
cally switch on or off according to
the coolant temperature in the
radiator.
If the engine overheats, see page
6-39 for further instructions.
EAUS1540
Engine trouble warning light “ ”
This warning light flashes if a problem
is detected in the electrical circuit
monitoring the engine. If this occurs,
have a Yamaha dealer check the self-
diagnosis system.
The electrical circuit of the warning
light can be checked by turning the
key to “ ”. If the warning light does
not come on for a few seconds, then
go off, have a Yamaha dealer check
the electrical circuit.

EAU15596
Inspect your vehicle each time you use it to make sure the vehicle is in safe operating condition. Always follow the ins-
pection and maintenance procedures and schedules described in the Owner’s Manual.
EWA11151
Failure to inspect or maintain the vehicle properly increases the possibility of an accident or equipment dama-
ge. Do not operate the vehicle if you find any problem. If a problem cannot be corrected by the procedures pro-
vided in this manual, have the vehicle inspected by a Yamaha dealer.
Before using this vehicle, check the following points:
WARNING
ITEMCHECKS PAGE
• Check fuel level in fuel tank.
Fuel • Refuel if necessary. 3-8
• Check fuel line for leakage.
• Check oil level in oil tank.
2-stroke engine oil • If necessary, add recommended oil to specified level. 3-10
• Check vehicle for oil leakage.
Transmission oil • Check oil level in transmission case.
• If necessary, add recommended oil to specified level. 6-13
• Check coolant level in reservoir.
Coolant • If necessary, add recommended coolant to specified level. 6-14
• Check cooling system for leakage.
• Check operation.
• If soft or spongy, have Yamaha dealer bleed hydraulic system.
• Check brake pads for wear.
Front brake • Replace if necessary. 6-23, 6-24
• Check fluid level in reservoir.
• If necessary, add recommended brake fluid to specified level.
• Check hydraulic system for leakage.

4. Remove the oil filler cap, refillwith the specified amount of the
recommended transmission oil,
and then install and tighten the oil
filler cap. NOTICE: Make sure
that no foreign material enters
the transmission case.
[ECAM1021]
5. Start the engine and let it idle for several minutes while checking
the transmission oil case for oil
leakage. If oil is leaking, imme-
diately turn the engine off and
check for the cause.
EAU20070
Coolant
The coolant level should be checked
before each ride. In addition, the coo-
lant must be changed at the intervals
specified in the periodic maintenance
and lubrication chart.
EAU39087
To check the coolant level1. Place the vehicle on a level surfa- ce and hold it in an upright posi-
tion.
TIP
The coolant level must be chec-
ked on a cold engine since the
level varies with engine tempera-
ture.
Make sure that the vehicle is
positioned 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 thecoolant reservoir.
TIP
The coolant should be between the
minimum and maximum level marks.
1. Coolant reservoir
2. Maximum level mark
3. Minimum level mark
3. If the coolant is at or below theminimum level mark, remove
panel A to access the coolant
reservoir. (See page 6-8).
4. Remove the coolant reservoir cap, add coolant to the maxi-
mum level mark, and then install
the reservoir cap. WARNING!
Remove only the coolant reser-
voir cap. Never attempt to
remove the radiator cap when
the engine is hot.

NOTICE: If coolant is not avai-
lable, 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 coolant
as soon as possible, otherwise
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.

To change the coolant 1. Place the vehicle on a level surfa- ce and let the engine cool if
necessary.
2. Remove cowlings A, B and C and panel A. (See page 6-8).
3. Place a container under the engi- ne to collect the used coolant.
4. Remove the radiator cap retai- ning bolt, radiator cap retainer
and radiator cap. WARNING!
Never attempt to remove the
radiator cap when the engine is
hot.

clamp back to its original posi-
tion.
10. Install the coolant drain bolt and its new gasket, and then tighten
the bolt to the specified torque.
11. Pour the recommended coolant into the reservoir to the maximum
level mark, and then install the
coolant reservoir cap.
12. Pour the recommended coolant into the radiator until it is full. 13. Install the radiator cap, start the
engine, let it idle for several minu-
tes, and then turn it off.
14. Remove the radiator cap to check the coolant level in the
radiator. If necessary, add suffi-
cient coolant until it reaches the
top of the radiator, and then ins-
tall the radiator cap, retainer and
retaining bolt.

coolant is leaking, have a Yama-
ha dealer check the cooling sys-
tem.
17. Install the cowlings and panel.EAU40371
Air filter element
The air filter element should be clea-
ned or replaced at the intervals speci-
fied in the periodic maintenance and
lubrication chart. Have a Yamaha
dealer clean or replace the air filter
element.
EAU21280
Adjusting the carburetor
The carburetor is an important part of
the engine and requires very sophisti-
cated adjustment. Therefore, most
carburetor adjustments should be left
to a Yamaha dealer, who has the
necessary professional knowledge
and experience. The adjustment des-
cribed in the following section, howe-
ver, may be serviced by the owner as
part of routine maintenance.
ECA10550
The carburetor has been set and
extensively tested at the Yamaha
factory. Changing these settings
without sufficient technical know-
ledge may result in poor perfor-
mance of or damage to the engine.
