PRE-OPERATION CHECKS
4The condition of a vehicle is the owner’s responsibility. Vital components can start to deteriorate quickly and unexpectedly,
even if the vehicle remains unused (for example, as a result of exposure to the elements). Any damage, fluid leakage or
loss of tire air pressure could have serious consequences. Therefore, it is very important, in addition to a thorough visual
inspection, to check the following points before each ride.
ITEM CHECKS PAGE
•Check fuel level in fuel tank.
Fuel•Refuel if necessary.3-6•Check fuel line for leakage.
•Check oil level in oil tank.
Two-stroke engine oil•If necessary, add recommended oil to specified level. 3-7•Check vehicle for oil leakage.
Final transmission oil•Check oil level and vehicle for oil leakage. 6-6
•Check operation.
•If soft or spongy, have Yamaha dealer bleed hydraulic system.
Front brake•Check fluid level in reservoir. 3-4, 6-11
•If necessary, add recommended brake fluid to specified level.
•Check hydraulic system for leakage.
•Check operation.
Rear brake•Check lever free play. 3-5, 6-11•Adjust if necessary.
•Make sure that operation is smooth.
Throttle grip•Check cable free play.

•
Become thoroughly familiar
with all operating controls and
their functions before riding.
Consult a Yamaha dealer
regarding any control or
function that you do not
thoroughly understand.
•
Never start the engine or
operate it in a closed area for
any length of time. Exhaust fu-
mes are poisonous, and
inhaling them can cause loss of
consciousness and death
within a short time. Always
make sure that there is
adequate ventilation.
•
For safety, always start the
engine with the centerstanddown.

”, then when
the oil level warning light comes
on, turn it to “
”.
ECA00045
For maximum engine life, never
accelerate hard when the engine iscold!
2. Turn the starter (choke) on and
completely close the throttle. (See
page 3-7 for starter (choke)
operation.)3. Start the engine by pushing the
start switch or by pushing the
kickstarter lever down, while
applying the front or rear brake.
NOTE :
If the engine fails to start by pushing
the start switch, release the switch, wait
a few seconds, and then try again. Each
starting attempt should be as short as
possible to preserve the battery. Do not
crank the engine more than 5 seconds
on any one attempt. If the engine does
not start with the starter motor, try usingthe kickstarter.
4. After starting the engine, move the
starter (choke) knob/lever back
halfway.

Tips for reducing fuel
consumptionFuel consumption depends largely on
your riding style. Consider the following
tips to reduce fuel consumption:•
Thoroughly warm up the engine.
•
Avoid high engine speeds during
acceleration.
•
Avoid high engine speeds with no
load on the engine.
•
Turn the engine off instead of
letting it idle for an extended
length of time (e.g., in traffic jams,
at traffic lights or at railroad
crossings).
EAU00436
Engine break-inThere is never a more important period
in the life of your engine than the period
between 0 and 1,000 km. For this
reason, you should read the following
material carefully.
Since the engine is brand new, do not
put an excessive load on it for the first
1,000 km. The various parts in the
engine wear and polish themselves to
the correct operating clearances.
During this period, prolonged full-
throttle operation or any condition that
might result in engine overheating must
be avoided.
EAUT0003*
0 - 150 km
Avoid operation above 1/3 throttle. Stop
the engine and let it cool for 5 to 10
minutes after every hour of operation.
Vary the speed of the scooter from time
to time. Do not operate it at one set
throttle position.150 - 500 km
Avoid prolonged operation above 1/2
throttle.
500 - 1,000 km
Avoid cruising speeds in excess of 3/4
throttle.
ECAT0001*
After 1,000 km of operation, be sureto replace the final transmission oil.
1,000 km and beyond
Avoid prolonged full throttle operation.
Vary speeds occasionally.
EC000049
If any engine trouble should occur
during the engine break-in period,
immediately have a Yamaha dealercheck the vehicle.
