3. Measure the spark plug gap with a wire thickness gauge and, if nec-
essary, adjust the gap to specifica-
tion.
To install the spark plug 1. Clean the surface of the spark plug gasket and its mating surface, and
then wipe off any grime from the
spark plug threads.
2. Install the spark plug with the spark plug wrench, and then tight-
en it to the specified torque.
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 finger tight. However, the spark
plug should be tightened to the speci-
fied torque as soon as possible.
3. Install the spark plug cap.
4. Install the panel.

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 specified 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. Wait a few minutes until the oil set- tles, remove the oil filler cap, wipe
the dipstick clean, insert it back
into the oil filler hole (without
screwing it in), and then remove it
again to check the oil level.TIPThe engine oil should be between theminimum and maximum level marks.
Specified spark plug:NGK / CPR9EA-9
Spark plug gap: 0.8–0.9 mm (0.031–0.035 in)
Tightening torque: Spark plug: 13 Nm (1.3 m·kgf, 9.4 ft·lbf)


Do not use oils with a diesel
specification of “CD” or oils of a
higher quality than specified. In addition, do not use oils labeled
“ENERGY CONSERVING II” or
higher.

Be sure no foreign material en-ters the crankcase.
9. Start the engine, and then let it idle for several minutes while checking
it for oil leakage. If oil is leaking, im-
mediately turn the engine off and
check for the cause.
10. Turn the engine off, and then check the oil level and correct it if
necessary.
To reset the oil change indicator
and oil change tripmeter
TIPThe oil change indicator and oil change
tripmeter can be reset when "OIL
CHANGE" and "OIL TRIP" appear in
the multi-function display. (Seepage 3-3.)

Final transmission oilThe final transmission case must be
checked for oil leakage before each
ride. If any leakage is found, have a
Yamaha dealer check and repair the
scooter. In addition, the final transmis-
sion oil must be changed as follows at
the intervals specified in the periodic
maintenance and lubrication chart. 1. Start the engine, warm up the final transmission oil by riding the
scooter for several minutes, and
then stop the engine.
2. Place the scooter on the center- stand.
3. Place an oil pan under the final transmission case to collect the
used oil.
4. Remove the final transmission oil filler cap and its O-ring from the fi-
nal transmission case.
Tightening torque:Engine oil drain bolt A: 20 Nm (2.0 m·kgf, 14.5 ft·lbf)
Engine oil drain bolt B:
32 Nm (3.2 m·kgf, 23.1 ft·lbf)
Recommended engine oil: See page 8-1.

CoolantThe coolant level should be checked
before each ride. In addition, the cool-
ant must be changed at the intervals
specified in the periodic maintenance
and lubrication chart.
EAUT3693
To check the coolant level
The coolant level should be checked as
follows before each ride. In addition,
the coolant must be changed at the in-
tervals specified in the periodic mainte-
nance and lubrication chart.1. Place the vehicle on the center- stand.TIP
The coolant level must be checked
on a cold engine since the level
varies with engine temperature.

Make sure that the vehicle is posi-
tioned straight up when checking
the coolant level. A slight tilt to theside can result in a false reading.
2. Open the seat. (See page 3-11.)
3. Check the coolant level in the cool- ant reservoir.
