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. UB427BE0.book Page 55 Friday, February 5, 2016 2:14 PM

Engine overheating
Wait for the engine to cool before removing the radiator cap. WARNING! If the engine is not
cool when removing the radiator cap, hot fluid and steam could blow out under pressure
and burn you.
[EWB03460]
Place a thick rag over the cap and remove the cap slowly to allow any re-
maining pressure to escape.
TIPIf it is difficult to get the recommended coolant, tap water can be used temporarily, provided that
it is changed to the recommende d coolant as soon as possible. Wait until the
engine has cooled.
Check the coolant level in the
coolant reservoir and/or radiator.
Level is OK.Level is low, check the
cooling system for leakage.
No
leakage.Leakage.
Ask a Yamaha dealer to inspect
and repair the cooling system.Add coolant. (See TIP.)
Restart the engine. If the engine overheats again, ask a
Yamaha dealer to inspect and/or repair the cooling system.

CLEANING AND STORAGE
EBU32731CleaningFrequent, thorough cleaning of your vehicle
will not only enhance its appearance but will
improve its general performance and extend
the useful life of many components.1. Before cleaning the vehicle: a. Block off the end of the exhaust pipeto prevent water entry. A plastic bag
and strong rubber band may be used.
b. Make sure the spark plug and all filler caps are properly installed.
2. If the engine case is excessively greasy, apply degreaser with a paint brush. Do
not apply degreaser to the wheel axles.
3. Rinse the dirt and degreaser off with a garden hose. Use only enough pressure
to do the job. WARNING! Test the
brakes after washing. Apply the
brakes several times at slow speeds to
let friction dry the brakes. Wet brakes may have reduced stopping ability, in-
creasing the chance of an accident.
[EWB03471]

NOTICE: Excessive water pres-
sure may cause water seepage and
deterioration of wheel bearings,
brakes, transmission seals and electri-
cal devices. Many expensive repair
bills have resulted from improper high-
pressure detergent applications such
as those available in coin-operated car
washers.
[ECB00712]
TIPThe tailgate can be removed to make it easier
to clean the cargo bed. To separate the tail-
gate from the cargo bed, unhook the latches,
lift the left side of the tailgate and pull the tail-
gate to the left. 4. Once the majority of the dirt has been hosed 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 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 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.
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.
Specified amount: 1 oz of stabilizer to each gallon of fuel (or
7.5 ml of stabilizer to each liter of fuel)

4. Put the frame on stands or blocks to raiseall 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.
