6Tightening torque:
Spark plug:
17.5 Nm (1.75 m
•kg)
NOTE :
If 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
specified torque as soon as possible.
4. Install the spark plug cap.
5. Install the cowling.

Engine oil
The engine oil level should be checked
before each ride. In addition, the oil
must be changed at the intervals
specified in the periodic maintenance
and lubrication chart and when the oil
change indicator comes on.To check the engine oil level
1. Place the scooter on the
centerstand.
NOTE :
Make sure that the scooter is positioned
straight up when checking the oil level.
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.

6CAUTION:
1. Engine oil drain bolt
2. Washer

4. Check the washer for damage and
replace it if necessary.
5. Install the washer and the engine
oil drain bolt, and then tighten the
drain bolt to the specified torque.
Tightening torque:
Engine oil drain bolt:
20 Nm (2.0 m
•kgf)
NOTE :
Make sure that the washer is properly
seated.6. Add the specified amount of the
recommended engine oil, and
then install and tighten the oil filler
cap.
Recommended engine oil:
See page 8-1.
Oil quantity:
Periodic oil change:
1.2 L
Total amount (dry engine):
1.4 L7. Start the engine, and then let it idle
for several minutes while checking
it for oil leakage. If oil is leaking,
immediately turn the engine off
and check for the cause.
8. Reset the oil change indicator.
(See page 3-7 for details.)

•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
enters the crankcase.

PERIODIC MAINTENANCE AND MINOR REPAIR
6Observe these precautions:
•When checking the fluid level,
make sure that the top of the brake
fluid reservoir is level.
•Use only the recommended
quality brake fluid, otherwise the
rubber seals may deteriorate,
causing leakage and poor braking
performance.
Recommended brake fluid:
DOT 4
1. Minimum level mark
•Refill with the same type of brake
fluid. Mixing fluids may result in a
harmful chemical reaction and
lead to poor braking performance.
•Be careful that water does not
enter the brake fluid reservoir
when refilling. Water will
significantly lower the boiling point
of the fluid and may result in vapor
lock.
•Brake fluid may deteriorate
painted surfaces or plastic parts.
Always clean up spilled fluid
immediately.
•As the brake pads wear, it is nor-
mal for the brake fluid level to
gradually go down. However, if the
brake fluid level goes down
suddenly, have a Yamaha dealer
check the cause.
EAUM0008*
Changing the brake fluid
Have a Yamaha dealer change the
brake fluid at the intervals specified in
the periodic maintenance and
lubrication chart. In addition, have the
brake hoses replaced every four years
or whenever they are damaged or
leaking.

Checking and lubricating the
cables
The operation of all control cables and
the condition of the cables should be
checked before each ride, and the cables
and cable ends should be lubricated if
necessary. If a cable is damaged or does
not move smoothly, have a Yamaha dea-
ler check or replace it.
Recommended lubricant:
Engine oil
EW000112
Damage to the outer sheath may
interfere with proper cable operation
and will cause the inner cable to rust.
Replace a damaged cable as soon
as possible to prevent unsafe con-
ditions.
WARNING
EAU04034
Checking and lubricating the
throttle grip and cable
The operation of the throttle grip should
be checked before each ride. In addi-
tion, the cable should be lubricated or
replaced at the intervals specified in the
periodic maintenance chart.

The condition and operation of the front
fork must be checked as follows at the
intervals specified in the periodic main-
tenance and lubrication chart.
To check the condition

there is no danger of it falling over.
Check the inner tubes for scratches,
damage and excessive oil leakage.
