TIPIf the odometer, tripmeter, or oil change
tripmeter indicates “-----”, have a Yama-
ha dealer check the multi-function dis-play.
OdometerTIPFor the U.K.: The odometer and tripme-
ter units can be switched from kilome-
ters to miles by pushing the “SELECT”button for 1 second.
Tripmeter
To reset the tripmeter, select it by push-
ing the “SELECT” button until “TRIP” isdisplayed, and then push the “RESET”
button for 1 second.
Oil change tripmeter
To reset the oil change tripmeter, select
it by pushing the “SELECT” button until
the oil change tripmeter is displayed,
and then push the “RESET” button for
3 seconds.
Push the “SELECT” button again to
start the oil change tripmeter; the dis-
play changes to the ODO mode.
Oil change indicator “OIL
CHANGE”
This indicator flashes at the initial 1000
km (600 mi), then at every 3000 km
(1800 mi) thereafter to indicate that the
engine oil should be changed.
After changing the engine oil, reset the
oil change tripmeter.
If the engine oil is changed before the
oil change indicator flashes (i.e. before
the periodic oil change interval has
been reached), the oil change tripmeter
must be reset after the oil change for
the next periodic oil change to be indi-
cated at the correct time.1. Odometer

TIP
Air filter and V-belt filter
This model’s air filter is equipped with a disposable oil-coated paper elemen t, which must not be cleaned with com-
pressed air to avoid damaging it.
The air filter element needs to be replaced and V-belt filter needs to be serviced more frequently when riding in un- usually wet or dusty areas.

Hydraulic brake service
After disassembling the brake master cylinder and caliper , always change the fluid. Regularly check the brake fluid
level and fill the reservoir as required.
Every two years replace the internal components of the brake master cylinder and caliper, and change the brake fluid. Replace the brake hose every four years and if cracked or damaged.

erosion and excessive carbon or
other deposits, and replace it if
necessary.
To install the spark plug 1. Measure the spark plug gap with a wire thickness gauge and, if nec-
essary, adjust the gap to specifica-
tion.
2. Clean the surface of the spark plug gasket and its mating surface, and
then wipe off any grime from the spark plug threads.
3. 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.
4. Install the spark plug cap.
5. Install the panel.
EAUT4160
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 level1. 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.

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.
4. If the engine oil is below the mini- mum level mark, add sufficient oil
of the recommended type to raise
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 and clean
the oil strainer 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.
3. Remove the engine oil filler cap and the engine oil drain bolts A
and B to drain the oil from the
crankcase. NOTICE: When re- moving the engine oil drain bolt
B, the O-ring, compression
spring, and oil strainer will fall
out. Take care not to lose these
parts.
[ECAT1022]
4. Clean the oil strainer with solvent,
and then check it for damage and
replace it if necessary.
5. Check the O-ring for damage and replace it if necessary.
6. Install the oil strainer, compression spring, O-ring and engine oil drain
bolt B.TIPMake sure that the O-ring is properlyseated.
