WARNING
EWB02522Gasoline and gasoline vapors are ex-
tremely flammable. To avoid fires and ex-
plosions and to reduce the risk of injury
when refueling, follow these instructions. 1. Before refueling, turn off the engine andbe sure that no one is sitting in the vehi-
cle.
Never refuel while smoking, or while in
the vicinity of sparks, open flames, or
other sources of ignition such as the pilot
lights of water heaters and clothes dry-
ers.
2. Do not overfill the fuel tank. Because fuel expands when it heats up, heat from the
engine or the sun can cause fuel to spill
out of the fuel tank.
3. Wipe up any spilled fuel immediately.
4. Be sure the fuel tank cap is closed se-
curely.
WARNING
EWB02532Gasoline is poisonous and can cause inju-
ry or death. Handle gasoline with care.
Never siphon gasoline by mouth. If you
should swallow some gasoline or inhale a
lot of gasoline vapor, or get some gasoline
in your eyes, see your doctor immediately.
If gasoline spills on your skin, wash with
soap and water. If gasoline spills on your
clothing, change your clothes. Your Yamaha engine has been designed to
use regular unleaded gasoline with a research
octane number of 91 or higher (95 or higher
for Europe). If knocking or pinging occurs,
use a different brand of gasoline or premium
unleaded gasoline. Unleaded fuel will give
you longer spark plug life and reduced main-
tenance cost.

For EuropeTIPWhen refueling, check that the gasoline pump
nozzle has same fuel identification mark.
Portable fuel containers
If you carry a portable fuel container in the
bed of your Yamaha Wolverine, be sure to se-
cure it with the cap tightened before driving
the vehicle.
Always place a portable fuel container on the
ground before filling it. Before removing the
container cap, touch the container with the
fuel dispenser nozzle. Keep fuel dispenser
nozzle in contact with container inlet when fill-
ing. WARNING! Never refill a fuel container
in the bed of any vehicle. Fire may result
from a build-up of static electricity. The
discharge of this build-up while refueling
can cause a spark and ignite the gasoline.[EWB03270]
EBU31750Engine oilMake sure the engine oil is at the specified
level. Add oil as necessary. (See page 8-14.)
Recommended fuel: Regular unleaded gasoline only
For Europe: Regular unleaded gasoline only

Installation1. Clean the surface of the spark plug gas-
ket and its mating surface, and then wipe
off any grime from the spark plug
threads.
2. Install the spark plug and tighten it to the specified torque. If a torque wrench is not
available when you are installing the
spark plug, a good estimate of the cor-
rect torque is one-quarter to one-half turn
past finger tight. Have the spark plug
tightened to the specified torque as soon
as possible.
3. Install the spark plug cap.
EBU33581Cleaning the air filter elementThe air filter element should be cleaned every
20–40 hours. It should be cleaned and lubri-
cated more often if the vehicle is operated in
extremely dusty areas. Each time air filter ele-
ment maintenance is performed, check the air
inlet to the air filter case for obstructions.
Check the air filter elem ent rubber joint to the
throttle body and manifold fittings for an air-
tight seal. Tighten all fittings securely to avoid
the possibility of unfiltered air entering the en-
gine.NOTICEECB02270Never operate the engine with the air filter
element removed. Doing so would allow
unfiltered air to enter, causing rapid en-
gine wear and possible engine damage.
Additionally, the fuel injection system
would be affected, re sulting in poor engine
performance and possible overheating.
Spark plug gap: 0.8–0.9 mm (0.031–0.035 in)
Tightening torque: Spark plug:11 N·m (1.1 kgf·m, 8.1 lb·ft)

EBU32460Valve clearanceThe correct valve clearance changes with
use, resulting in improper fuel/air supply or
engine noise. To prevent this, the valve clear-
ance must be adjusted regularly. This adjust-
ment however, should be left to a
professional Yamaha service technician.EBU32470BrakesReplacement of brake components requires
professional knowledge. Brake service
should be performed by a Yamaha dealer.
WARNING
EWB02572Operating with improperly serviced or ad-
justed brakes could lead to a loss in brak-
ing ability and an accident.
EBU32480Checking the front and rear brake padsEach brake pad is provided with wear indica-
tor grooves, which allow you to check the
brake pad wear without having to disassem-
ble the brake. To check the brake pad wear,
check the wear indicator grooves. If a brake
pad has worn to the point that the wear indi-
cator grooves have almost disappeared, have
a Yamaha dealer replace the brake pads as a
set.
The wheels need to be removed to check the
brake pads. (See pages 8-45, 8-47 for wheel
removal and installation procedures.)

5. Start the engine. (See page 6-2.)
6. After the engine starts, disconnect thenegative lead of the jumper cable from
the frame and charged battery, and then
disconnect the positive lead of the jump-
er cable from the charged battery and the
battery in the vehicle.
7. Install the hood.

tion to check if the device operates. If the fuse blows again immediately, have a
Yamaha dealer check the electrical sys-
tem.

EBU33590Tail/brake light bulb replacementIf a tail/brake light bulb burns out, replace it as
follows:1. Remove the tail/brake light bulb holder
(together with the bulb) by turning it
counterclockwise.
2. Push the burnt-out bulb in and turn it counterclockwise to remove it from the
bulb holder.
3. Push a new bulb in and turn it clockwise to install in the bulb holder. 4. Install the bulb holder (together with the
bulb) by turning it clockwise.
EBU32700TroubleshootingAlthough Yamaha vehicles receive an inspec-
tion before shipment from the factory, trouble
may occur during operation. Any problem in
the fuel, compression, or ignition systems can
cause poor starting and loss of power. The
troubleshooting chart describes a quick, easy
procedure for making checks. If your vehicle
requires any repair, take it to a Yamaha deal-
er.
The skilled technicians at a Yamaha dealer-
ship have the tools, experience, and know-
how to properly service your vehicle. Use only
genuine Yamaha parts on your vehicle. Imita-
tion parts may look like Yamaha parts, but
they are often inferior. Consequently, they
have a shorter service life and can lead to ex-
pensive repair bills.

WARNING
EWB03450When checking the fuel system, do not
smoke and make sure there are no open
flames or sparks in the area, including pilot
lights from water heaters or furnaces.
Gasoline or gasoline vapors can ignite or
explode, causing severe injury or property
damage. UB3D7AE0.book Page 58 Tuesday, November 7, 2017 9:38 AM
