Avoid braking hard or sudden-
ly (especially when leaning
over to one side), otherwise
the scooter may skid or over-
turn.
8 8
Railroad crossings, streetcar
rails, iron plates on road con-
struction sites, and manhole
covers become extremely slip-
pery when wet. Therefore,
slow down when approaching
such areas and cross them
with caution.
8 8
Keep in mind that braking on a
wet road is much more diffi-
cult.
8 8
Ride slowly down a hill, as
braking downhill can be very
difficult.
EAU04755
Tips for reducing fuel
consumption
Fuel consumption, tips for reducing
Fuel consumption depends largely on
your riding style. Consider the follow-
ing tips to reduce fuel consumption:
8Avoid high engine speeds during
acceleration.
8Avoid high engine speeds with
no load on the engine.
8Turn 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 cross-
ings).

Engine break-inEngine break-in
There is never a more important peri-
od in the life of your engine than the
period between 0 and 1,600 km. For
this reason, you should read the fol-
lowing material carefully.
Since the engine is brand new, do
not put an excessive load on it for the
first 1,600 km. The various parts in
the engine wear and polish them-
selves to the correct operating clear-
ances. During this period, prolonged
full-throttle operation or any condition
that might result in engine overheat-
ing must be avoided.
EAU03845*
0–1,000 km
Avoid prolonged operation above 1/3
throttle.
1,000–1,600 km
Avoid prolonged operation above 1/2
throttle.
ECA00080
cC
After 1,000 km of operation, the
engine oil must be changed, and
the oil filter cartridge replaced.
1,600 km and beyond
The vehicle can now be operated
normally.
EC000049
cC
If any engine trouble should occur
during the engine break-in period,
immediately have a Yamaha dealer
check the vehicle.

ParkingParking
When parking, stop the engine, and
then remove the key from the main
switch.

8 8
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.
8 8
Do not park on a slope or on
soft ground, otherwise the
scooter may overturn.

Safety is an obligation of the owner.
Periodic inspection, adjustment and
lubrication will keep your vehicle in
the safest and most efficient condi-
tion possible. The most important
points of inspection, adjustment, and
lubrication are explained on the fol-
lowing pages.
The intervals given in the periodic
maintenance and lubrication chart
should be simply considered as a
general guide under normal riding
conditions. However, DEPENDING
ON THE WEATHER, TERRAIN,
GEOGRAPHICAL LOCATION, AND
INDIVIDUAL USE, THE MAINTE-
NANCE INTERVALS MAY NEED TO
BE SHORTENED.

assist you in the performance of pre-
ventive maintenance and minor
repairs. However, additional tools
such as a torque wrench may be nec-
essary to perform certain mainte-
nance work correctly.

er maintenance intervals.
