OPERATION AND IMPORTANT RIDING POINTS

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.
EAUM2280
0–500 km (0–300 mi)
Avoid prolonged operation above 1/3
throttle.
500–1000 km (300–600 mi)
Avoid prolonged operation above 1/2
throttle.
CAUTION:
ECAM1090
After 1000 km (600 mi) of operation,
the engine oil and final transmission
oil must be changed, and the engineoil filter element replaced.
1000 km (600 mi) and beyond
The vehicle can now be operated nor-
mally.CAUTION:
ECA10270
If any engine trouble should occur
during the engine break-in period,
immediately have a Yamaha dealercheck the vehicle.
EAU17212
Parking When parking, stop the engine, and
then remove the key from the main
switch.
WARNING
EWA10310


Since the engine and exhaust
system can become very hot,
park in a place where pedestri-
ans or children are not likely to
touch them.


Do not park on a slope or on soft
ground, otherwise the vehiclemay overturn.
CAUTION:
ECA10380
Never park in an area where there
are fire hazards such as grass orother flammable materials.

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
EWA11310


Make sure that no foreign mate-
rial enters the final transmission
case.


Make sure that no oil gets on thetire or wheel.
7. Check the final transmission case
for oil leakage. If oil is leaking,
check for the cause.
