Installation
1. Measure the electrode gap with a wire thick-
ness gauge and, if necessary, adjust the gap
to specification.
2. Clean the surface of the spark plug gasket
and its mating surface, and then wipe off any
grime from the spark plug threads.
3. 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 correct torque is
one-quarter to one-half turn past finger tight.
Have the spark plug tightened to the speci-
fied torque as soon as possible.
4. Install the spark plug cap.
5. Reinstall the console.Spark plug gap:
0.8–0.9 mm (0.031–0.035 in)
Tightening torque:
Spark plug:
12.5 Nm (1.25 m·kgf, 9.0 ft·lbf)

brush to remove any carbon deposits from
the spark arrester portion of the tailpipe and
inside of the tailpipe housing.
4. Install the gasket, and then insert the tailpipe
into the muffler and align the bolt holes.
5. Install the bolts and tighten them to the spec-
ified torque.

Troubleshooting
Although Yamaha vehicles receive an inspection
before shipment from the factory, trouble may oc-
cur during operation. Any problem in the fuel, com-
pression, or ignition systems can cause poor
starting and loss of power. The troubleshooting
chart describes a quick, easy procedure for mak-
ing checks. If your vehicle requires any repair, take
it to a Yamaha dealer.
The skilled technicians at a Yamaha dealership
have the tools, experience, and know-how to prop-
erly service your vehicle. Use only genuine
Yamaha parts on your vehicle. Imitation parts may
look like Yamaha parts, but they are often inferior.
Consequently, they have a shorter service life and
can lead to expensive repair bills.
WARNING
When 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 gaso-
line vapors can ignite or explode, causing se-
vere injury or property damage.

1-CLEANING AND STORAGE
A. Cleaning
Frequent, 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 pipe to
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, ap-
ply degreaser with a paint brush. Do not ap-
ply degreaser to the wheel axles.

B. Storage
Long term storage (60 days or more) of your vehi-
cle will require some preventive procedures to
guard against deterioration. Make any necessary
repairs before storing the vehicle.
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. Oper-
ate the vehicle for at least 5 minutes to dis-
tribute treated fuel through the fuel system.
2. Remove the spark plug, pour about one ta-
blespoon of SAE 10W-40 or 20W-50 motor
oil in the spark plug hole and reinstall the
spark plug. Ground the spark plug wire and
turn the engine over several times to coat the
cylinder wall with oil. Specified amount:
1 oz of stabilizer to each gallon of fuel
(or 7.5 ml of stabilizer to each liter of fuel)
