Tripmeter
To reset the tripmeter, select it by push-
ing the “SELECT” button until “TRIP” is
displayed, and then push the “RESET”
button at least 1 second.
NOTE:

If the tripmeter indicates “-----”, have a
Yamaha dealer check the multi-func-
tion display, as it may be faulty.
Oil change tripmeter
To reset the oil change tripmeter, select
it by pushing the “SELECT” button until
“OIL CHANGE TRIP” is displayed, and
then push the “RESET” button at least
3 seconds. After resetting the oil
change tripmeter, “ODO” will be dis-
played.
NOTE:

If the “SELECT” button is pushed again
or the “SELECT” button hasn’t been
pushed within 10 seconds, the oil
change tripmeter will keep counting
and “ODO” will be displayed.
Oil change indicator
Oil change indicator “”
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.
NOTE:


If the oil change tripmeter is reset
before the initial 1000 km (600 mi),
the next periodic oil change inter-

EAU16820
Tips for reducing fuel
consumption
Fuel consumption depends largely on
your riding style. Consider the following
tips to reduce fuel consumption:

Avoid high engine speeds during
acceleration.

Avoid high engine speeds with no
load on the engine.

Turn the engine off instead of let-
ting it idle for an extended length of
time (e.g., in traffic jams, at traffic
lights or at railroad crossings).
EAU16830
Engine break-in
There is never a more important period
in the life of your engine than the period
between 0 and 1000 km (600 mi). For
this reason, you should read the follow-
ing material carefully.
Since the engine is brand new, do not
put an excessive load on it for the first
1000 km (600 mi). The various parts in
the engine wear and polish themselves
to the correct operating clearances.
During this period, prolonged full-throt-
tle operation or any condition that might
result in engine overheating must be
avoided.
EAU16950
0–150 km (0–90 mi)
Avoid prolonged operation above 1/3
throttle.
After every hour of operation, stop the
engine, and then let it cool for five to ten
minutes.
Vary the engine speed from time to
time. Do not operate the engine at one
set throttle position.
150–500 km (90–300 mi)
Avoid prolonged operation above 1/2
throttle.
Rev the engine freely through the
gears, but do not use full throttle at any
time.
500–1000 km (300–600 mi)
Avoid prolonged operation above 3/4
throttle.
CAUTION:

ECA10350
After 1000 km (600 mi) of operation,
the engine oil must be changed and
the oil strainer cleaned.
1000 km (600 mi) and beyond
Avoid prolonged full-throttle operation.
Vary the speed occasionally.
CAUTION:

ECA10270
If any engine trouble should occur
during the engine break-in period,
immediately have a Yamaha dealer
check the vehicle.

Engine oil and oil strainer
The 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. The engine oil must also be
changed at the initial 1000 km (600 mi)
and when the oil change indicator flash-
es. The oil change tripmeter must be
reset after the initial 1000 km (600 mi).
(See page 3-2 for reset procedures.)
To check the engine oil level
1. Place the vehicle on the center-
stand.
NOTE:

Make sure that the vehicle 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.
3. Wait a few minutes until the oil set-
tles, remove the oil filler cap, wipe
the dipstick clean, insert it backinto the oil filler hole (without
screwing it in), and then remove it
again to check the oil level.
NOTE:

The engine oil should be between the
minimum 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 drain bolts to drain the oil from
the crankcase.
CAUTION:

ECA10410
When removing the engine oil drain
bolt, the O-ring, spring, and oil
strainer will fall out. Take care not to
lose these parts.

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, spring,O-ring and engine oil drain bolts,
and then tighten the drain bolts to
the specified torque.
NOTE:

Make sure that the O-ring is properly
seated.
7. Add the specified amount of the
recommended engine oil, and then
install and tighten the engine oil fill-
er cap.
CAUTION:

ECA11670

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” orhigher.

Be sure no foreign material en-
ters the crankcase.
8. 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.
9. Turn the engine off, and then
check the oil level and correct it if
necessary.
10. Reset the oil change tripmeter.
(See page 3-2 for reset proce-
dures.)
NOTE:

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.

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 transmis-
sion 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 center-
stand.
3. Place an oil pan under the final
transmission case to collect the
used oil.
4. Remove the oil filler cap and drain
bolt to drain the oil from the final
transmission case.5. Install the final transmission oil
drain bolt, and then tighten it to the
specified torque.6. Add the specified amount of the
recommended final transmission
oil, and then install and tighten the
oil filler cap.
WARNING
