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

• 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.

EAU16800
Tips for reducing fuel
consumption
Fuel consumption depends largely on
your riding style. Consider the follo-
wing tips to reduce fuel consumption:
Turn the starter (choke) off as
soon as possible.
Shift up swiftly, and avoid high
engine speeds during accelera-
tion.
Do not rev the engine while shif-
ting down, and avoid high engine
speeds with no load on the engi-
ne.
Turn the engine off instead of let-
ting it idle for an extended length
of time (e.g., in traffic jams, at
traffic lights or at railroad cros-
sings).
EAU16830
Engine break-in
There is never a more important
period in the life of your engine than
the period between 0 and 1000 km
(600 mi). For this reason, you should
read the following material carefully.
Since the engine is brand new, do not
put an excessive load on it for the first
1000 km (600 mi). The various parts in
the engine wear and polish themsel-
ves to the correct operating clearan-
ces. During this period, prolonged
full-throttle operation or any condition
that might result in engine overhea-
ting must be avoided.
EAUS1560
0–500 km (0–300 mi)
Avoid prolonged operation above
4000 r/min.
After every hour of operation,
stop the engine, and then let it
cool for five to ten minutes.
Vary the engine speed from time
to time. Do not operate the engi-
ne at one set throttle position.500–1000 km (300–600 mi)
Avoid prolonged operation above
6000 r/min.
Rev the engine freely through the
gears, but do not use full throttle
at any time.
NOTICE:After 1000
km (600 mi) of operation, the
transmission oil must be chan-
ged.
[ECA10370]
1000 km (600 mi) and beyond
The vehicle can now be operated
normally.
ECA10310
Keep the engine speed out of
the tachometer red zone.
If any engine trouble should
occur during the engine break-
in period, immediately have a
Yamaha dealer check the vehi-
cle.

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.

TIP
Make sure that two notches in the
axle nut are aligned with the hole
through the wheel axle, otherwise
further tighten the axle nut until they
are.
6. Make sure that the drive chainpullers are in the same position,
the drive chain slack is correct,
and the drive chain moves smo-
othly.
EAU23025
Cleaning and lubricating the
drive chain
The drive chain must be cleaned and
lubricated at the intervals specified in
the periodic maintenance and lubrica-
tion chart, otherwise it will quickly
wear out, especially when riding in
dusty or wet areas. Service the drive
chain as follows.
ECA10583
The drive chain must be lubricated
after washing the motorcycle,
riding in the rain or riding in wet
areas.
1. Clean the drive chain with kero-sene and a small soft brush.
NOTICE: To prevent damaging
the O-rings, do not clean the
drive chain with steam clea-
ners, high-pressure washers or
inappropriate solvents.
[ECA11121]
2. Wipe the drive chain dry.
3. Thoroughly lubricate the drive chain with a special O-ring chain
lubricant. NOTICE: Do not use
engine oil or any other lubri-
cants for the drive chain, as they may contain substances
that could damage the O-rings.

Checking and lubricating the
cables
The operation of all control cables
and the condition of the cables
should be checked before each ride,
and the cables and cable ends should
be lubricated if necessary. If a cable is
damaged or does not move smoothly,
have a Yamaha dealer check or repla-
ce it. WARNING! Damage to the
outer housing of cables may result
in internal rusting and cause inter-
ference with cable movement.
Replace damaged cables as soon
as possible to prevent unsafe con-
ditions.
[EWA10711]EAU23114
Checking and lubricating the
throttle grip and cable
The operation of the throttle grip
should be checked before each ride.
In addition, the cable should be lubri-
cated by a Yamaha dealer at the inter-
vals specified in the periodic mainte-
nance chart.
The throttle cable is equipped with a
rubber cover. Make sure that the
cover is securely installed. Even
though the cover is installed correctly,
it does not completely protect the
cable from water entry. Therefore, use
care not to pour water directly onto
the cover or cable when washing the
vehicle. If the cable or cover becomes
dirty, wipe clean with a moist cloth.
EAU23120
Adjusting the Autolube pump
The Autolube pump is a vital and sop-
histicated component of the engine,
which must be adjusted by a Yamaha
dealer at the intervals specified in the
periodic maintenance and lubrication
chart.
Recommended lubricant:
Yamaha Chain and Cable Lube or
engine oil

EAU23272
Checking the front fork
The condition and operation of the
front fork must be checked as follows
at the intervals specified in the perio-
dic maintenance and lubrication
chart.
To check the condition1. Check the inner tubes for scrat- ches, damage and excessive oil
leakage.
To check the operation 1. Place the vehicle on a level surfa- ce and hold it in an upright posi-
tion. WARNING! To avoid injury,
securely support the vehicle so
there is no danger of it falling
over.
[EWA10751]
2. While applying the front brake, push down hard on the handle-
bars several times to check if the
front fork compresses and
rebounds smoothly.
ECA10590
If any damage is found or the front
fork does not operate smoothly,
have a Yamaha dealer check or
repair it.
EAU23283
Checking the steering
Worn or loose steering bearings may
cause danger. Therefore, the opera-
tion of the steering must be checked
as follows at the intervals specified in
the periodic maintenance and lubrica-
tion chart.1. Place a stand under the engine to raise the front wheel off the
ground. WARNING! To avoid
injury, securely support the
vehicle so there is no danger of
it falling over.
[EWA10751]
2. Hold the lower ends of the front fork legs and try to move them for-
ward and backward. If any free
play can be felt, have a Yamaha
dealer check or repair the steering.
