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 and repair the vehicle before
any further operation.EBU32520Brake fluid replacementComplete fluid replacement should be done
only by trained Yamaha service personnel.
Have a Yamaha dealer replace the following
components during pe riodic maintenance or
when they are damaged or leaking.
Replace the oil seals every two years.
Replace the brake hoses every four years.
EBU32530Checking the brake pedalHave a Yamaha dealer check the brakes at
the intervals specified in the periodic mainte-
nance and lubrication chart. There should be
no free play in the brake pedal. The brakes
should operate smoothly and there should be
no brake drag. If the brakes feel soft or
spongy, this could indicate air in the brake
system. Have a Yamaha dealer check the
brake system if necessary.1. Brake pedal

WARNING
EWB03400Do not reverse the rims on your Yamaha
Wolverine to widen the track width. Install-
ing wheels improperly increases the risk of
wheel failure and accidents. EBU32640BatteryThe battery is located under the hood. (See
page 8-10 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 dis-
tilled water. However, the battery lead con-
nections need to be checked and, if
necessary, tightened.
WARNING
EWB03410Avoid 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.
Tightening torques:Front wheel nut:75 N·m (7.5 kgf·m, 54 lb·ft)
Rear wheel nut: 75 N·m (7.5 kgf·m, 54 lb·ft)

5. Wait for the headlight bulb to cool beforetouching 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 adversely affected.
Thoroughly clean off any dirt and fin-
gerprints on the headlight bulb using a
cloth moistened with alcohol or thin-
ner.
[ECB00652]
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-
curely fitted over the bulb holder and
seated properly.
[ECB02210]
9. Adjust the headlight beam if necessary.1. Do not touch the glass part of the bulb.

4. Once the majority of the dirt has beenhosed off, wash all surfaces with warm
water and mild, detergent-type soap. An
old toothbrush or bottle brush is handy
for hard-to-get-at places.
5. Rinse the vehicle off immediately with
clean water and dry all surfaces with a
clean chamois towel or soft, absorbent
cloth.
6. Clean the seats with a vinyl upholstery cleaner to keep the covers pliable and
glossy.
7. Automotive-type wax may be applied to all painted and chrome-plated surfaces.
Avoid combination cleaner-waxes. Many
contain abrasives which may scratch the
paint or protective finish. When finished,
start the engine and let it idle for several
minutes.
EBU36120StorageLong term storage (60 days or more) of your
vehicle will require some preventive proce-
dures to guard against deterioration. Make
any necessary repairs be fore 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 Fuel Med Rx or
another high-quality fuel stabilizer prod-
uct. Follow the instructions on the prod-
uct label. Operate the vehicle for at least
5 minutes to distribute treated fuel
through the fuel system.
2. Remove the spark plug and pour one ta- blespoon of fresh engine oil into the cyl-
inder and then re-install the spark plug.Specified amount:1 oz of stabilizer to each gallon of fuel (or
7.5 ml of stabilizer to each liter of fuel)

Remove the spark plug wire and ground
it. Operate the electric starter to turn the
engine over several times and coat the
cylinder walls with oil.
3. Lubricate all control cables.
4. Put the frame on stands or blocks 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.
7. Remove the battery and charge it. Store
it in a dry place and recharge it once a
month. Do not store the battery in an ex-
cessively warm or cold place [less than 0
°C (30 °F) or more than 30 °C (90 °F)].
Use of fuel stabilizer eliminates the need to
drain the fuel system. Consult a Yamaha
dealer if the fuel system needs to be drained.
