PERIODIC MAINTENANCE AND MINOR REPAIR
EAU17280
Safety is an obligation of the owner. Pe-
riodic inspection, adjustment and lubri-
cation will keep your vehicle in the
safest and most efficient condition pos-
sible. The most important points of in-
spection, adjustment, and lubrication
are explained on the following pages.
The intervals given in the periodic
maintenance and lubrication chart
should be simply considered as a gen-
eral guide under normal riding condi-
tions. However, DEPENDING ON THE
WEATHER, TERRAIN, GEOGRAPHI-
CAL LOCATION, AND INDIVIDUAL
USE, THE MAINTENANCE INTER-
VALS MAY NEED TO BE SHORT-
ENED.
WARNING

EWA10320
If you are not familiar with mainte-
nance work, have a Yamaha dealer
do it for you.
WARNING

EWA10330
This scooter is designed for use on
paved roads only. If this scooter isoperated in abnormally dusty, mud-
dy or wet conditions, the air filter el-
ement should be cleaned or
replaced more frequently, otherwise
rapid engine wear may result. Con-
sult a Yamaha dealer for proper
maintenance intervals.
EAU17390
Owner’s tool kit
The owner’s tool kit is located under the
seat. (See page 3-17.)
The service information included in this
manual and the tools provided in the
owner’s tool kit are intended to assist
you in the performance of preventive
maintenance and minor repairs. How-
ever, additional tools such as a torque
wrench may be necessary to perform
certain maintenance work correctly.
NOTE:

If you do not have the tools or experi-
ence required for a particular job, have
1. Helmet holding cable
2. Owner’s tool kit

Checking the spark plugs
The spark plugs are important engine
components, which should be checked
periodically, preferably by a Yamaha
dealer. Since heat and deposits will
cause any spark plug to slowly erode,
they should be removed and checked
in accordance with the periodic mainte-
nance and lubrication chart. In addition,
the condition of the spark plugs can re-
veal the condition of the engine.
The porcelain insulator around the cen-
ter electrode of each spark plug should
be a medium-to-light tan (the ideal color
when the vehicle is ridden normally),
and all spark plugs installed in the en-
gine should have the same color. If any
spark plug shows a distinctly different
color, the engine could be operating im-
properly. Do not attempt to diagnose
such problems yourself. Instead, have
a Yamaha dealer check the vehicle.
If a spark plug shows signs of electrode
erosion and excessive carbon or other
deposits, it should be replaced.Before installing a spark plug, the spark
plug gap should be measured with a
wire thickness gauge and, if necessary,
adjusted to specification.
Clean the surface of the spark plug
gasket and its mating surface, and then
wipe off any grime from the spark plug
threads.
NOTE:

If a torque wrench is not available wheninstalling 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.

5. Check the washer and O-ring for
damage and replace them if nec-
essary.
NOTE:

Skip steps 6–8 if the oil filter cartridge is
not being replaced.
6. Remove the oil filter cartridge with
an oil filter wrench.
NOTE:

An oil filter wrench is available at a
Yamaha dealer.
7. Apply a thin coat of engine oil to
the O-ring of the new oil filter car-
tridge.
NOTE:

Make sure that the O-ring is properly
seated.
8. Install the new oil filter cartridge,
and then tighten it to the specified
torque with a torque wrench.

then tighten it to the specified

10. Add the specified amount of the
recommended engine oil, and then
install and tighten the oil filler cap.
NOTE:

Be sure to wipe off spilled oil on any
parts after the engine and exhaust sys-
tem have cooled down.
CAUTION:

ECA11620

In order to prevent clutch slip-
page (since the engine oil also
lubricates the clutch), do not
mix any chemical additives. Do
not use oils with a diesel speci-
fication of “CD” or oils of a high-
er quality than specified. In
addition, do not use oils labeled
“ENERGY CONSERVING II” or
higher.

Make sure that no foreign mate-
rial enters the crankcase.
11. 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.
12. Turn the engine off, and then
check the oil level and correct it if
necessary.
13. Reset the oil change indicator.
(See page 3-9.)
NOTE:

If the engine oil is changed before the
oil change indicator comes on (i.e. be-
fore the periodic oil change interval has
been reached), the indicator must be
reset after the oil change for the next

Rear brake pads
1. Remove the rear brake caliper by
removing the bolts.
2. Check each rear brake pad for
damage and measure the lining
thickness. If a brake pad is dam-
aged or if the lining thickness is
less than 0.8 mm (0.03 in), have a
Yamaha dealer replace the brake
pads as a set.
3. Install the rear brake caliper by in-stalling the bolts, then tightening
them to the specified torque.
