TIP
Engine air filter and V-belt air filters
• This model’s engine air filter is equipped with a disposable oil-coated paper element, which must not be cleaned
with compressed air to avoid damaging it.
• The engine air filter element needs to be replaced and the V-belt air filter elements need to be serviced more fre-
quently when riding in unusually wet or dusty areas.
Hydraulic brake service
• After disassembling the brake master cylinders and calipers, always change the fluid. Regularly check the brake
fluid levels and fill the reservoirs as required.
• Every two years replace the internal components of the brake master cylinders and calipers, and change the bra-
ke fluid.
• Replace the brake hoses every four years and if cracked or damaged.

Checking the spark plug
The spark plug is an important engine
component, which should be chec-
ked periodically, preferably by a
Yamaha dealer. Since heat and depo-
sits will cause any spark plug to
slowly erode, it should be removed
and checked in accordance with the
periodic maintenance and lubrication
chart. In addition, the condition of the
spark plug can reveal the condition of
the engine.
The porcelain insulator around the
center electrode of the spark plug
should be a medium-to-light tan (the
ideal color when the vehicle is ridden
normally). If 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.
If the spark plug shows signs of elec-
trode erosion and excessive carbon
or other deposits, it should be repla-
ced.Before installing a spark plug, the
spark plug gap should be measured
with a wire thickness gauge and, if
necessary, adjusted to specification.
1. Spark plug gap
Clean the surface of the spark plug
gasket and its mating surface, and
then wipe off any grime from the
spark plug threads.
Spark plug gap:
0.8–0.9 mm (0.031–0.035 in)

TIP
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. Howe-
ver, the spark plug should be tighte-
ned to the specified torque as soon
as possible.
EAUS1711
Engine oil
The engine oil level should be chec-
ked before each ride. In addition, the
oil must be changed at the intervals
specified in the periodic maintenance
and lubrication chart and when the
service indicator light comes on.
To check the engine oil level
1. Place the scooter on the centers-
tand. 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
settles, remove the oil filler cap,
wipe the dipstick clean, insert it
back into the oil filler hole (wit-
hout screwing it in), and then
remove it again to check the oil
level.
TIP
The engine oil should be between the
minimum and maximum level marks.
1. Engine oil filler cap
2. Maximum level mark
3. Minimum level mark
4. If the engine oil is below the mini-
mum level mark, add sufficient oil
of the recommended type to rai-
se it to the correct level.
5. Insert the dipstick into the oil filler
hole, and then tighten the oil filler
cap.
To change the engine oil
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.

of the recommended engine oil,
and then install and tighten the oil
filler cap.

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 CONSER-
VING II” or higher.
Be sure no foreign material
enters the crankcase.
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 cau-
se.
8. Reset the oil change indicator.
To reset the oil change indicator
1. Turn the key to “ON”.
2. Hold the “OIL CHANGE” button
pushed for 15 to 20 seconds.

3. Release the “OIL CHANGE” but-
ton, and the oil change indicator
will go off.
TIP
If the engine oil is changed before the
oil change indicator comes on (i.e.
before the periodic oil change interval
has been reached), the indicator must
be reset after the oil change for the
next periodic oil change to be indica-
ted at the correct time. To reset the oil
change indicator before the periodic
oil change interval has been reached,
follow the above procedure, but note
that the indicator will come on for 1.4
seconds after releasing the “OILCHANGE” button, otherwise repeat
the procedure.

Final transmission oil
The 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 trans-
mission 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 centers-
tand.
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
final transmission case.
5. Remove the final transmission oil
drain bolt and its gasket to drain
the oil from the final transmission
case.
