TIP
This model is equipped with:  a lean angle sensor to stop the en-
gine in case of turnover. Turn the
main switch off once before at-
tempting to restart the engine.
Failing to do so will prevent the en-
gine from starting, even though
the engine will crank when the
start switch is pushed.
 an engine auto-stop system. The
engine stops automatically if left
idling for 20 minutes. In this case,
simply push the start switch to re-
start the engine.

Parkin g
When parking, stop the engine, and
then remove the key from the main
switch.
WARNING
EWA10312

EAU17246
Periodic inspection, adjustment, and
lubrication will keep your vehicle in the
safest and most efficient condition
possible. Safety is an obligation of the
vehicle owner/operator. The most im-
portant points of vehicle inspection,
adjustment, and lubrication are ex-
plained on the following pages.
The intervals given in the periodic
maintenance charts should be simply
considered as a general guide under
normal riding conditions. However, de-
pending on the weather, terrain, geo-
graphical location, and individual use,
the maintenance intervals may need to
be shortened.
WARNING
EWA10322
Failure to properly maintain the vehi-
cle or performin g maintenance ac-
tivities incorrectly may increase
your risk of injury or d eath durin g
service or while usin g the vehicle. If
you are not familiar with vehicle ser-
vice, have a Yamaha d ealer perform
service.
WARNING
EWA15123
Turn off the en gine when performin g
maintenance unless otherwise
specified .
 A runnin g en gine has movin g
parts that can catch on body
parts or clothin g an d electrical
parts that can cause shocks or
fires.
 Runnin g the en gine while ser-
vicin g can lead to eye injury,
b urns, fire, or car bon monoxi de
poisonin g – possi bly lea din g to d
eath. See pag e 1-3 for more in-
formation a bout car bon monox-
i d e.
WARNING
EWA15461
Brake discs, calipers, drums, an d
linin gs can b ecome very hot during
use. To avoi d possi ble burns, let
b rake components cool before
touchin g them.

TIP
Be sure to wipe off spilled oil on any
parts after the engine and exhaust sys-
tem have cooled down.
NOTICE
ECA11621
 In or der to prevent clutch slip-
pa ge (since the en gine oil also
lu bricates the clutch), do not
mix any chemical add itives. Do
not use oils with a d iesel speci-
fication of “CD” or oils of a hi gh-
er quality than specified . In
a ddition, do not use oils la bele d
“ENERGY CONSERVING II” or
hi gher.
 Make sure that no forei gn mate-
rial enters the crankcase.
15. Check the filler cap O-ring for damage, and replace it if neces-
sary.
16. Install and tighten the oil filler cap.
17. Start the engine, and then let it idle for several minutes while checking
it for oil leakage. If oil is leaking,
immediately turn the engine off
and check for the cause.
TIP
After the engine is started, the engine
oil level warning light should go off if
the oil level is sufficient.
NOTICE
ECA10402
If the oil level warnin g li ght flickers
or remains on even if the oil level is
correct, imme diately turn the en gine
off an d have a Yamaha dealer check
the vehicle.
18. Turn the engine off, and then check the oil level and correct it if
necessary.
19. Check the dipstick O-ring for damage, and replace it if neces-
sary.
20. Install the cowlings.

Coolant
The coolant level should be checked
regularly. In addition, the coolant must
be changed at the intervals specified in
the periodic maintenance chart.
TIP
If genuine Yamaha coolant is not avail-
able, use an ethylene glycol antifreeze
containing corrosion inhibitors for alu-
minum engines and mix with distilled
water at a 1:1 ratio.
EAU3908BTo check the coolant level
Since the coolant level varies with en-
gine temperature, check when the en-
gine is cold.
1. Park the vehicle on a level surface.
2. With the vehicle in an upright posi- tion, look at the coolant level in the
reservoir. 3. If the coolant is at or below the mi-
nimum level mark, remove panel B
to access the coolant reservoir.
(See page 7-7.)
4. Remove the coolant reservoir cap. WARNING! Remove only the
coolant reservoir cap. Never at-
tempt to remove the ra diator
cap when the en gine is hot.
[EWA15162]
5. Add coolant to the maximum level
mark. NOTICE: If coolant is not
availa ble, use distille d water or
soft tap water instea d. Do not
use har d water or salt water
since it is harmful to the en gine.
If water has been used instead
of coolant, replace it with cool-
ant as soon as possi ble, other-
wise the coolin g system will not
b e protecte d a gainst frost an d
corrosion. If water has b een
a dde d to the coolant, have a
Yamaha dealer check the anti-
freeze content of the coolant as
soon as possi ble, otherwise the
effectiveness of the coolant will
b e red uced.
[ECA10473]
6. Install the coolant reservoir cap.
7. Install the panel.
Recommen ded coolant:
YAMALUBE coolant
Coolant quantity: Coolant reservoir (max level mark):0.25 L (0.26 US qt, 0.22 Imp.qt)
Radiator (including all routes): 2.30 L (2.43 US qt, 2.02 Imp.qt)

Valve clearance
The valves are an important engine
component, and since valve clearance
changes with use, they must be
checked and adjusted at the intervals
specified in the periodic maintenance
chart. Unadjusted valves can result in
improper air-fuel mixture, engine
noise, and eventually engine damage.
To prevent this from occurring, have
your Yamaha dealer check and adjust
the valve clearance at regular intervals.
TIP
This service must be performed when
the engine is cold.
EAU70961
Tires
Tires are the only contact between the
vehicle and the road. Safety in all con-
ditions of riding depends on a relatively
small area of road contact. Therefore, it
is essential to maintain the tires in good
condition at all times and replace them
at the appropriate time with the speci-
fied tires.
Tire air pressure
The tire air pressure should be
checked and, if necessary, adjusted
before each ride.
WARNING
EWA18370
 Operation of this vehicle with
improper tire air pressure may
cause severe injury or d eath
from loss of control.
 The tire air pressure must b e
checked and a djuste d on col d
tires (i.e., when the temperature
of the tires equals the am bient
temperature).
WARNING
EWA10512
Never overloa d your vehicle. Opera-
tion of an overloa ded vehicle coul d
cause an acci dent.
Col d tire air pressure:
Front: 250 kPa (2.50 kgf/cm², 36 psi)
Rear:
290 kPa (2.90 kgf/cm², 42 psi)
