seat. (See page 3-11.)
The service information included in
this manual and the tools provided in
the owner’s tool kit are intended to as-
sist you in the performance of preven-
tive maintenance and minor repairs.
However, additional tools such as a
torque wrench may be necessary to
perform certain maintenance work
correctly.TIPIf you do not have the tools or expe-
rience required for a particular job,
have a Yamaha dealer perform it for
you.

1. Spark plug wrenchTo check the spark plug
1. Check that the porcelain insula-
tor around the center electrode
of the spark plug is a medium-to-
light tan (the ideal color when the
vehicle is ridden normally).TIPIf the spark plug shows a distinctly
different color, the engine could be
operating improperly. Do not attempt
to diagnose such problems yourself.
Instead, have a Yamaha dealer check
the vehicle.
2. Check the spark plug for elec-trode erosion and excessive
carbon or other deposits, and re-
place it if necessary.
Speci ed spark plug:
CPR9EA-9 (NGK)To install the spark plug
1. Measure the spark plug gap with
a wire thickness gauge and, if
necessary, adjust the gap to
specifi cation.Spark plug gap:
0.8 ~ 0.9 mm (0.031 ~ 0.035 in)2. Clean the surface of the spark
plug gasket and its mating sur-
face, and then wipe off any grime
from the spark plug threads.
3. Install the spark plug with the
spark plug wrench, and then
tighten it to the specifi ed torque.Tightening torque:
Spark plug:
13 Nm (1.3 m·kgf, 9.4 ft·lbf)
EAUT1835
Checking the spark plugThe spark plug is an important engine
component, which is easy to check.
Since heat and deposits will cause
any spark plug to slowly erode, the
spark plug should be removed and
checked in accordance with the pe-
riodic maintenance and lubrication
chart. In addition, the condition of the
spark plug can reveal the condition of
the engine.
To remove the spark plug
1. Place the vehicle on the center-
stand.
2. Remove panel C. (See page 6-8.)
3. Remove the spark plug cap.
4. Remove the spark plug as
shown, with the spark plug
wrench included in the owner’s
tool kit.

Engine oil and oil strainerThe engine oil level should be
checked before each ride. In addition,
the oil must be changed and the oil
strainer cleaned at the intervals speci-
fied in the periodic maintenance and
lubrication chart.
To check the engine oil level
1. Place the scooter on the center-
stand. A slight tilt to the side can
result in a false reading.
2. Start the engine, warm it up for
several minutes, and then turn it
off.

3. Minimum level mark
3. Wait a few minutes until the oil
settles, remove the oil filler cap,
wipe the dipstick clean, insert it
back into the oil fi ller hole (without
screwing it in), and then remove it
again to check the oil level.TIPThe engine oil should be between the
minimum and maximum level marks.
4. If the engine oil is below the mini-
mum level mark, add suffi cient oil
of the recommended type to raise
it to the correct level.
5. Insert the dipstick into the oil fi ller
hole, and then tighten the oil fi ller
cap.
To change the engine oil and clean
the oil strainer
1. Start the engine, warm it up for
several minutes, and then turn it
off.
2. Place an oil pan under the engine
to collect the used oil.
3. Remove the engine oil filler cap
and the engine oil drain bolts A
TIPIf a torque wrench is not available
when installing a spark plug, a good
estimate of the correct torque is 1/4 ~
1/2 turn past fi nger tight. However, the
spark plug should be tightened to the
specifi ed torque as soon as possible.
4. Install the spark plug cap.
5. Install the panel.
