8. Install the engine oil drain bolt and
its new gasket, and then tighten
the bolt to the specified torque.
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
ECA11621

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 oil pres-
sure and coolant temperature warning
light should go off if the oil level is suffi-cient.NOTICE
ECA22490
If the oil pressure and coolant tem-
perature warning light flickers or re-
mains 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.
12. Install the cowling and panel.

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.
EAU66510
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 cowl-
ing B. (See page 7-9.)
4. Remove the coolant reservoir cap, add coolant to the maximum level
mark, and then install the reservoir
cap. WARNING! Remove only
the coolant reservoir cap. Never
attempt to remove the radiator
cap when the engine is
hot.
[EWA15162]
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.

To change the coolant 1. Place the vehicle on a level sur- face and let the engine cool if nec-
essary.
2. Remove cowling B and panel D. (See page 7-9.)
3. Place a container under the engine to collect the used coolant.
4. Remove the radiator cap.
WARNING! Never attempt to re-
move the radiator cap when the
engine is hot.
[EWA10382]
5. Remove the coolant drain bolt andits gasket to drain the cooling sys-
tem. 6. Remove the coolant reservoir cap.
7. Remove the coolant reservoir by
removing the bolts, and then turn
the reservoir upside down to emp-
ty it. 8. After the coolant is completely
drained, thoroughly flush the cool-
ing system with clean tap water.
9. Install the coolant reservoir by in- stalling the bolts.
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.1. Radiator cap

16. Install the radiator cap.
17. Start the engine, let it idle for sev-
eral minutes, and then turn it off.
18. 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.
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 panel.

Drive chain slackThe drive chain slack should be
checked before each ride and adjusted
if necessary.
EAU74251
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. To prevent
this from occurring, keep the
drive chain slack within the
specified limits.
[ECA10572]
EAU74260
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.
TIPUsing the alignment marks on each
side of the swingarm, make sure that
both drive chain pullers are in the sameposition for proper wheel alignment.

Cleaning and lubricating the
drive chainThe 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.NOTICE
ECA10584
The drive chain must be lubricated
after washing the motorcycle, ridingin 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 cleaners,
high-pressure washers or inap-
propriate solvents.
[ECA11122]
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.

BatteryNOTICE
ECA22960
Use only the specified genuine
YAMAHA battery. Using a different
battery may cause the IMU to fail andthe engine to stall.
The battery is located under the rider
seat. (See page 4-37.)NOTICE
ECA22970
The IMU is located under the battery.
It is not user serviceable and very
sensitive, so we advise against re- moving the battery box or handling
the IMU directly.

Do not remove, modify, or place
any foreign materials in or
around the battery box.

Do not subject the IMU to strong
shocks and be careful when
handling the battery.

Do not obstruct the IMU breath-
er hole and do not clean it withcompressed air.
This model is equipped with a VRLA
(Valve Regulated Lead Acid) battery.
There is no need to check the electro-
lyte or to add distilled water. However,
the battery lead connections need to be
checked and, if necessary, tightened.WARNING
EWA10761

Electrolyte is poisonous and
dangerous since it contains sul-
furic acid, which causes severe
burns. Avoid any contact with
skin, eyes or clothing and al-
ways shield your eyes when
working near batteries. In case
of contact, administer the fol- lowing FIRST AID.
EXTERNAL: Flush with plenty
of water.
INTERNAL: Drink large quan- tities of water or milk and im-
mediately call a physician.
EYES: Flush with water for 15 minutes and seek prompt
medical attention.

Batteries produce explosive hy-
drogen gas. Therefore, keep
sparks, flames, cigarettes, etc.,
away from the battery and pro-
vide sufficient ventilation when
charging it in an enclosed
space.

KEEP THIS AND ALL BATTER-
IES OUT OF THE REACH OFCHILDREN.
To charge the battery
Have a Yamaha dealer charge the bat-
tery as soon as possi ble if it seems to
have discharged. Keep in mind that the
battery tends to discharge more quickly
if the vehicle is equipped with optional
electrical accessories.
