WARNING
Gasoline is poisonous and can cause injury 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 im-
mediately. 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. If knocking or pinging oc-
curs, use a different brand of gasoline or premium
unleaded fuel. Unleaded fuel will give you longer
spark plug life and reduced maintenance cost.

Periodic maintenance chart for the emission control system
For vehicles not equipped with an odometer or hour meter, follow the month maintenance intervals.
For vehicles equipped with an odometer or an hour meter, follow the km (mi) or hours maintenance in-
tervals. However, keep in mind that if the vehicle isn’t used for a long period of time, the month mainte-
nance intervals should be followed.
Items marked with an asterisk should be performed by a Yamaha dealer as they require special tools,
data and technical skills.

Spark plug inspection
Removal
1. Remove the console. (See pages 8-21–8-23
for console removal and installation proce-
dures.)
2. Remove the spark plug cap.
3. Use the spark plug wrench in the tool kit to re-
move the spark plug as shown.

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.
Specified spark plug:

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)
