Inspection
The spark plug is an important engine component
and is easy to inspect. The condition of the spark
plug can indicate the condition of the engine.
The ideal color of the porcelain insulator around
the center electrode is a medium-to-light tan for a
vehicle that is being ridden normally.
You should periodically remove and inspect the
spark plug because heat and deposits will cause
the spark plug to slowly break down and erode. If
electrode erosion becomes excessive, or if carbon
and other deposits are excessive, you should re-
place the spark plug with the specified plug.
Measure the spark plug gap with a wire thickness
gauge and, if necessary, adjust the gap to specifi-
cation.Specified spark plug:
CPR7EA-9 (NGK)
Spark plug gap:
0.8–0.9 mm (0.031–0.035 in)

The air filter element should be cleaned every 20–
40 hours. It should be cleaned and lubricated
more often if the vehicle is operated in extremely
dusty areas. Each time air filter element mainte-
nance is performed, check the air inlet to the air fil-
ter case for obstructions. Check the air filter
element rubber joint to the throttle body and mani-
fold fittings for an airtight seal. Tighten all fittings
securely to avoid the possibility of unfiltered air en-
tering the engine.NOTICENever operate the engine with the air filter ele-
ment removed. This will allow unfiltered air to
enter, causing rapid engine wear and possible
engine damage. Additionally, operation with-
out the air filter element will affect the fuel in-
jection system with subsequent poor
performance and possible engine overheating.

V-belt case drain plug
The V-belt case drain plug is located under the
driver seat. (See page 4-37 for seat removal and
installation procedures.)
After riding in water deep enough to allow water to
enter the V-belt case, remove the drain plug to
drain any water from the case.
If water drains from the V-belt case after removing
the drain plug, have a Yamaha dealer inspect the
vehicle, as the water may affect other engine
parts.

Cleaning the spark arrester
WARNING
Hot exhaust system may cause burns. To
avoid burns or fires, make sure that the engine
is stopped and the exhaust system is cool be-
fore cleaning the spark arrester. Do not start
the engine while cleaning the exhaust system.1. Remove the tailpipe bolts.
2. Remove the tailpipe by pulling it out of the
muffler, and then remove the gasket.
3. Tap the tailpipe lightly, and then use a wire
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.

Valve clearance
The correct valve clearance changes with use, re-
sulting in improper fuel/air supply or engine noise.
To prevent this, the valve clearance must be ad-
justed regularly. This adjustment however, should
be left to a professional Yamaha service techni-
cian.Tightening torque:
Tailpipe bolt:
10 Nm (1.0 m·kgf, 7.2 ft·lbf)

battery and the other end of the negative lead
to an unpainted metal surface of the crank-
case to be started.
7. Start the engine. (Refer to “Starting the en-
gine” on pages 6-7–6-11.)
8. After the engine starts, disconnect the nega-
tive lead of the jumper cable from the crank-
case and charged battery, and then
disconnect the positive lead of the jumper ca-
ble from the charged battery and the battery
in the vehicle.
9. Reinstall the console.
10. Reinstall the battery compartment cover.

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. Place
a thick rag over the cap and remove the cap slowly to allow any remaining pressure to escape.
If it is difficult to get the recommended coolant, tap water can be used temporarily, provided that it is
changed to the recommended 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 the text below.)
Restart the engine. If the engine overheats again, ask a
Yamaha dealer to inspect and/or repair the cooling system.

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.

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 cham-
ois towel or soft, absorbent cloth.
6. Clean the seats with a vinyl upholstery clean-
er 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 pro-
tective finish. When finished, start the engine
and let it idle for several minutes.
