Read the Owner’s Manual carefully to
become familiar with all controls. If
there is a control or function you do
not understand, ask your Yamaha
dealer.

Failure to familiarize yourself with
the controls can lead to loss of
control, which could cause an acci-
dent or injury.

Starting a cold engineECA10250
NOTICE
See page 5-4 for engine break-in
instructions prior to operating the
vehicle for the first time.
1. Turn the key to “ ”, and when
the oil level warning light comes
on, turn it to “ ”.
ECA10240
NOTICE
If the oil level warning light does
not come on, have a Yamaha dealer
check the electrical circuit.
2. Close the throttle completely.3. While applying the front or rear
brake, start the engine by pus-
hing the start switch or by pus-
hing the kickstarter lever down.
NOTICE: For maximum engine
life, never accelerate hard
when the engine is cold!
[ECA11041]
If the engine fails to start by pus-
hing 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
using the kickstarter.

sWARNING
●Avoid braking hard or suddenly
(especially when leaning over
to one side), otherwise the sco-
oter may skid or overturn.
●Railroad crossings, streetcar
rails, iron plates on road cons-
truction sites, and manhole
covers become extremely slip-
pery when wet. Therefore, slow
down when approaching such
areas and cross them with cau-
tion.
●Keep in mind that braking on a
wet road is much more difficult.
●Ride slowly down a hill, as bra-
king downhill can be very diffi-
cult.
1. Close the throttle completely.
2. Apply both front and rear brakes
simultaneously while gradually
increasing the pressure.Front

Tips for reducing fuel
consumption
Fuel consumption depends largely on
your riding style. Consider the follo-
wing 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 cros-
sings).

TIP
●The air filter needs more frequent service if you are riding in unusually wet or dusty areas.
●Hydraulic brake service
• Regularly check and, if necessary, correct the brake fluid level.
• Every two years change the brake fluid.
• Replace the brake hoses every four years and if cracked or damaged.

Checking the spark plug
The spark plug is an important engine
component, which should be chec-
ked periodically, preferably by a
Yamaha dealer. Since heat and depo-
sits will cause any spark plug to
slowly erode, it should be removed
and checked in accordance with the
periodic maintenance and lubrication
chart. In addition, the condition of the
spark plug can reveal the condition of
the engine.
The porcelain insulator around the
center electrode of the spark plug
should be a medium-to-light tan (the
ideal color when the vehicle is ridden
normally). If the spark plug shows a
distinctly different color, the engine
could be operating improperly. Do not
attempt to diagnose such problems
yourself. Instead, have a Yamaha
dealer check the vehicle.
If the spark plug shows signs of elec-
trode erosion and excessive carbon
or other deposits, it should be repla-
ced.Before installing a spark plug, the
spark plug gap should be measured
with a wire thickness gauge and, if
necessary, adjusted to specification.
1. Spark plug gap
Clean the surface of the spark plug
gasket and its mating surface, and
then wipe off any grime from the
spark plug threads.
Spark plug gap:
0.6–0.7 mm (0.024–0.028 in)

6. Refill with the specified amount
of the recommended final trans-
mission oil, and then install and
tighten the oil filler cap. WAR-
NING! Make sure that no
foreign material enters the final
transmission case. Make sure
that no oil gets on the tire or
wheel.
[EWA11311]
7. Check the final transmission case
for oil leakage. If oil is leaking,
check for the cause.
EAUS1200
Coolant (CS50Z)
The coolant level should be checked
before each ride. In addition, the coo-
lant must be changed at the intervals
specified in the periodic maintenance
and lubrication chart.
EAUM2102
To check the coolant level
1. Place the vehicle on a level surfa-
ce and hold it in an upright posi-
tion.
TIP
●The coolant level must be chec-
ked on a cold engine since the
level varies with engine tempera-
ture.
●Make sure that the vehicle is
positioned straight up when
checking the coolant level. A
slight tilt to the side can result in
a false reading.
2. Check the coolant level through
the check window.
TIP
The coolant should be between the
minimum and maximum level marks.
1. Coolant level check window
2. Maximum level mark
3. Minimum level mark
3. If the coolant is at or below the
minimum level mark, remove the
cowling A. (See page 6-5).
4. Open the reservoir cap, and then
add coolant to the maximum
level mark. WARNING! Remove
only the coolant reservoir cap.
Never attempt to remove the
radiator cap when the engine is
hot.
[EWA15161]. NOTICE: If coolant
is not available, use distilled
