WARNING
Improper maintenance can result in loss of
braking ability. Observe these precau-
tions:●
Insufficient brake fluid may allow air
to enter the brake system, reducing
braking performance.
●
Clean the filler cap before removing.
Use only DOT 4 brake fluid from a
sealed container.
●
Use only the specified brake fluid;
otherwise, the rubber seals may dete-
riorate, causing leakage.
●
Refill with the same type of brake flu-
id. Adding a brake fluid other than
DOT 4 may result in a harmful chemi-
cal reaction.
●
Be careful that water does not enter
the brake fluid reservoir when refill-
ing. Water will significantly lower the
boiling point of the fluid and may re-
sult in vapor lock.
NOTICEBrake fluid may damage painted surfaces
or plastic parts. Always clean up spilled
fluid immediately.As the brake pads wear, it is normal for the
brake fluid level to gradually go down. A low
brake fluid level may indicate worn brake
pads and/or brake system leakage; therefore,
be sure to check the brake pads for wear and
the brake system for leakage. If the brake fluid
level goes down suddenly, have a Yamaha
dealer check the cause before further riding.EVU00860Brake fluid replacementComplete fluid replacement should be done
only by trained Yamaha service personnel.
Have a Yamaha dealer replace the following
components during periodic maintenance or
when they are damaged or leaking.●
Replace the oil seals every two years.
●
Replace the brake hoses every four years.

EVU00950BatteryThe battery is located under the hood. (See
page 8-7 for hood removal and installation
procedures.)
This model is equipped with a VRLA (Valve
Regulated Lead Acid) battery. There is no
need to check the electrolyte or to add distilled
water. However, the battery lead connections
need to be checked and, if necessary, tight-
ened.
WARNING
Avoid battery contact with skin, eyes, or
clothing. Shield eyes when working near
batteries. Keep out of reach of children.
You could be poisoned or severely burned
by the sulfuric acid in battery electrolyte.
In case of accidental contact with battery
electrolyte:
EXTERNAL: Flush with water.
INTERNAL: Drink large quantities of water
or milk. Follow with milk of magnesia,
beaten egg, or vegetable oil. Get prompt
medical attention.
EYES: Flush with water for 15 minutes and
get prompt medical attention.
WARNING
Batteries may produce explosive gases.
Ventilate when charging or using in a
closed space. Keep batteries away from
sparks, flames, cigarettes, or other sourc-
es of ignition.

5. Wait for the headlight bulb to cool before touching or removing it. Remove the
burnt-out bulb by pulling it out.
6. Place a new headlight bulb into position, and then secure it with the bulb holder.
NOTICE: Do not touch the glass part
of the headlight bulb to keep it free
from oil, otherwise the transparency
of the glass, the luminosity of the
bulb, and the bulb life will be adverse-
ly affected. Thoroughly clean off any
dirt and fingerprints on the headlight
bulb using a cloth moistened with al-
cohol or thinner.
1. Do not touch the glass part of the bulb.7. Connect the headlight coupler.
8. Install the bulb cover and the cover at the rear of the headlight. NOTICE: Make
sure the headlight bulb cover is se-

5B410025StorageLong term storage (60 days or more) of your
vehicle will require some preventive proce-
dures to guard against deterioration. Make
any necessary repairs before storing the vehi-
cle.
After thoroughly cleaning the vehicle, prepare
for storage as follows:1. Fill the fuel tank with fresh fuel and add
the specified amount of Yamaha Fuel
Stabilizer and Conditioner or equivalent
product. Operate the vehicle for at least
5 minutes to distribute treated fuel
through the fuel system. 2. Remove the spark plug, pour about one
tablespoon of SAE 10W-40 or 20W-50
motor oil in the spark plug hole and install
the spark plug. Ground the spark plug
wire and turn the engine over several
times to coat the cylinder wall with oil.
3. Lubricate all control cables.
4. Block up the frame to raise all wheels off the ground.
5. Tie a plastic bag over the exhaust pipe outlet to prevent moisture from entering.
6. If storing in a humid or salt-air atmo-
sphere, coat all exposed metal surfaces
with a light film of oil. Do not apply oil to
any rubber parts or the seat covers.
Specified amount:
1 oz of stabilizer to each gallon of fuel (or
7.5 ml of stabilizer to each liter of fuel)1XP7C_EE.book Page 3 Monday, June 9, 2014 5:17 PM
