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.To check the engine oil level
1. Place the scooter on the center-
stand.
NOTE:
Make sure that the scooter is posi-
tioned 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.

Engine oilEngine oilThe engine oil level should be
checked before each ride. In addition,
the oil must be changed at the inter-
vals specified in the periodic mainte-
nance and lubrication chart and when
the oil change indicator light comes
on. Tightening torque:
Spark plug:
17.5 Nm (1.75 m·kgf)

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.
NOTE:
Make sure that the washer is properly
seated.

7. 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
light according to the following
procedure. 6. Add the specified amount of the
recommended engine oil, and
then install and tighten the oil
filler cap.

cC8Do not put in any chemical
additives or use oils with a
grade of CD or higher. Also, be
sure not to use oils labeled
“ENERGY CONSERVING
II” or
higher.
8Be sure no foreign material
enters the crankcase.
Tightening torque:
Engine oil drain bolt:

67. Check the final transmission
case for oil leakage. If oil is leak-
ing, check for the cause.
EAU04591
CoolantCoolantThe coolant reservoir is located
under the battery cover. (See page
6-34 for battery cover removal and
installation procedures.)
To check the coolant level
1. Place the scooter on a level sur-
face and hold it in an upright
position.NOTE:
8The coolant level must be
checked on a cold engine since
the level varies with engine tem-
perature.
8Make sure that the scooter is
positioned straight up when
checking the coolant level. A
slight tilt to the side can result in
a false reading.
2. Check the coolant level in the
coolant reservoir.NOTE:
The coolant should be between the
minimum and maximum level marks.

6 8Refill with the same type of brake
fluid. Mixing fluids may result in a
harmful chemical reaction and
lead to poor braking perfor-
mance.
8Be careful that water does not
enter the brake fluid reservoir
when refilling. Water will signifi-
cantly lower the boiling point of
the fluid and may result in vapor
lock.
8Brake fluid may deteriorate paint-
ed surfaces or plastic parts.
Always clean up spilled fluid
immediately.
8As 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.
EAU03976
Changing the brake fluidBrake fluid, changingHave a Yamaha dealer change the
brake fluid at the intervals specified in
the NOTE after the periodic mainte-
nance and lubrication chart. In addi-
tion, have the oil seals of the master
cylinders and calipers as well as the
brake hoses replaced at the intervals
listed below or whenever they are
damaged or leaking.
8Oil seals: Replace every two
years.
8Brake hoses: Replace every four
years.
EAU02962
Checking and lubricating the
cablesCables, checking and lubricatingThe 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 dealer
check or replace it.
EW000112
wDamage to the outer sheath may
interfere with proper cable opera-
tion and will cause the inner cable
to rust. Replace a damaged cable
as soon as possible to prevent
unsafe conditions.
Recommended lubricant:

Checking the front forkFront fork, checkingThe condition and operation of the
front fork must be checked as follows
at the intervals specified in the peri-
odic maintenance and lubrication
chart.
To check the condition
EW000115
wSecurely support the scooter so
that there is no danger of it falling
over.Check the inner tubes for scratches,
damage and excessive oil leakage.To check the operation
1. Place the scooter on a level sur-
face and hold it in an upright
position.
2. While applying the front brake,
push down hard on the handle-
bars several times to check if the
front fork compresses and
rebounds smoothly.
EC000098
cCIf any damage is found or the front
fork does not operate smoothly,
have a Yamaha dealer check or
repair it.
