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 4-34.)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 possible 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.

Engine overheating
WARNING
EWAT1041

Do not remove the radiator cap when the engine and radiator are hot. Scalding hot fluid and steam may be
blown out under pressure, which could cause serious injury. Be sure to wait until the engine has cooled.

Place a thick rag, like a towel, over the radiator cap, and then slowly rotate the cap counterclockwise to the de-
tent to allow any residual pressure to escape. When the hissing sound has stopped, press down on the capwhile turning it counterclockwise, and then remove the cap.
TIPIf coolant is not available, tap water can be temporarily
used instead, provided that it is changed to the recommended coolantas soon as possible.
Wait until the
engine has cooled.
Check the coolant level in the
reservoir and radiator.
The coolant level
is OK.The coolant level is low.
Check the cooling system
for leakage.
Have a Yamaha dealer checkand repair the cooling system.Add coolant. (See TIP.)
Start the engine. If the engine overheats again,
have a
Yamaha dealer check
and repair the cooling system.

5. Treat rubber, vinyl, and unpainted
plastic parts with a suitable care
product.
6. Touch up minor paint damage caused by stones, etc.
7. Wax all painted surfaces using a non-abrasive wax or use a detail
spray for motorcycles.
8. When finished cleaning, start the engine and let it idle for several
minutes to help dry any remaining
moisture.
9. If the headlight lens has fogged up, start the engine and turn on the
headlight to help remove the mois-
ture.
10. Let the vehicle dry completely be- fore storing or covering it.NOTICE
ECA26320

Do not apply wax to rubber or
unpainted plastic parts.

Do not use abrasive polishing
compounds as they will wear
away the paint.

Apply sprays and wax sparing-ly. Wipe off excess afterwards.
WARNING
EWA20660
Contaminants left on the brakes or
tires can cause loss of control.
Make sure there is no lubricant
or wax on the brakes or tires.

If necessary, wash the tires with
warm water and a mild deter-
gent.

If necessary, clean the brake
discs and pads with brake
cleaner or acetone.

Before riding at higher speeds,
test the vehicle’s braking perfor-mance and cornering behavior.

Cleaning the titanium muffler
This model is equipped with a titanium
muffler which requires special care.
Use only a soft cloth or sponge and
mild detergent with water to clean the
muffler. This should remove finger-
prints and other oil stains. If necessary,
an alkaline pH cleaning product and
soft brush may be used. However, do
not use abrasive compounds or special
treatments to clean the muffler, as
these will wear away the protective fin- ish.
TIPThe thermally induced discoloring of
the exhaust pipe leading into the titani-
um muffler is normal and cannot be re-moved.

StorageAlways store the vehicle in a cool, dry
place. If necessary, protect it against
dust with a porous cover. Be sure the
engine and the exhaust system are
cool before covering the vehicle. If the
vehicle often sits for weeks at a time
between uses, the use of a quality fuel
stabilizer is recommended after each
fill-up.NOTICE
ECA21170

Storing the vehicle in a poorly
ventilated room or covering it
with a tarp, while it is still wet,
will allow water and humidity to
seep in and cause rust.

To prevent corrosion, avoid
damp cellars, stables (because
of the presence of ammonia)
and areas where strong chemi-cals are stored.
Long term storage
Before storing the vehicle long term (60
days or more): 1. Make all necessary repairs and perform any outstanding mainte-
nance.
2. Follow all instructions in the Care section of this chapter.
3. Fill up the fuel tank, adding fuel stabilizer according to product in-
structions. Run the engine for 5
minutes to distribute treated fuel
through the fuel system.
4. For vehicles equipped with a fuel cock: Turn the fuel cock lever to
the off position.
5. For vehicles with a carburetor: To prevent fuel deposits from building
up, drain the fuel in the carburetor
float chamber into a clean contain-
er. Retighten the drain bolt and
pour the fuel back into the fuel
tank.
6. Use a quality engine fogging oil ac- cording to product instructions to
protect internal engine compo-
nents from corrosion. If engine fog-
ging oil is not available, perform
the following steps for each cylin-
der:
a. Remove the spark plug cap and spark plug.
b. Pour a teaspoonful of engine oil into the spark plug bore.
c. Install the spark plug cap onto the spark plug, and then place
the spark plug on the cylinder
head so that the electrodes are
grounded. (This will limit spark-
ing during the next step.)
d. Turn the engine over several times with the starter. (This will
coat the cylinder wall with oil.)
WARNING! To prevent dam-
age or injury from sparking,
make sure to ground the
spark plug electrodes while
turning the engine
over.
[EWA10952]
e. Remove the spark plug capfrom the spark plug, and then
install the spark plug and the
spark plug cap.
7. Lubricate all control cables, pivots, levers and pedals, as well as the
sidestand and centerstand (if
equipped).
8. Check and correct the tire air pres- sure, and then lift the vehicle so
that all wheels are off the ground.
Otherwise, turn the wheels a little
once a month in order to prevent
