TIPThe engine is sensitively monitored by
the on-board diagnostic system to de-
tect deterioration or malfunction of the
emission control system. Therefore the
MIL may come on or flash due to vehi-
cle modifications, lack of maintenance,
or excessive/improper use of the mo-
torcycle. To prevent this, observe
these precautions.
 Do not attempt to modify the soft-
ware of the engine control unit.
 Do not add any electrical acces-
sories that interfere with engine
control.
 Do not use aftermarket accesso-
ries or parts such as suspension,
spark plugs, injectors, exhaust
system, etc.
 Do not change the drivetrain
specifications (chain, sprockets,
wheels, tires, etc.).
 Do not remove or alter the O2 sen-
sor, air induction system, or ex-
haust parts (catalysts or EXUP,
etc.).
 Maintain the drive chain properly.
 Maintain correct tire pressure. 
Maintain proper brake pedal
height to prevent rear brake from
dragging.
 Do not operate the vehicle in an
extreme manner. For example, re-
peated or excessive opening and
closing of the throttle, racing,
burnouts, wheelies, extended
half-clutch use, etc.

ABS warnin g li ght “ ”
In normal operation, the ABS warning
light comes on when the vehicle is
turned on, and goes off after traveling
at a speed of 10 km/h (6 mi/h) or high-
er.TIPIf the warning light does not work as
described above, or if the warning light
comes on while riding, the ABS may
not work correctly. Have a Yamaha
dealer check the vehicle as soon as
possible.
WARNING
EWA16043
If the ABS warnin g li ght does not
turn off after reachin g 10 km/h (6
mi/h), or if the warnin g li ght comes
on while ri din g:
 Use extra caution to avoi d pos-
si ble wheel lock d uring emer-
g ency brakin g.
 Have a Yamaha d ealer check
the vehicle as soon as possi ble.

Shift in dicator li ght “ ”
This indicator light comes on when it is
time to shift to the next higher gear.
The engine speeds at which it comes
on or goes off can be adjusted. (See
page 4-26.)TIPWhen the vehicle is turned on, this light
should come on for a few seconds and
then go off. If the light does not come
on, or if the light remains on, have a
Yamaha dealer check the vehicle.

Periodic maintenance chartsTIPItems marked with an asterisk should be performed by your Yamaha dealer because these items require special tools,
data, and technical skills.
 From 50000 km (30000 mi), repeat the maintenance intervals starting from 10000 km (6000 mi).
 The annual checks must be performed every year, except if a distance-based maintenance is performed in-
stead.

Checking the spark plugsThe spark plugs are important engine
components, which should be
checked periodically, preferably by a
Yamaha dealer. Since heat and depos- its will cause any spark plug to slowly
erode, they should be removed and
checked in accordance with the peri-
odic maintenance and lubrication
chart. In addition, the condition of the
spark plugs can reveal the condition of
the engine.
The porcelain insulator around the
center electrode of each spark plug
should be a medium-to-light tan (the
ideal color when the vehicle is ridden
normally), and all spark plugs installed
in the engine should have the same
color. If any spark plug shows a dis-
tinctly different color, the engine could
be operating improperly. Do not at-
tempt to diagnose such problems
yourself. Instead, have a Yamaha deal-
er check the vehicle.
If a spark plug shows signs of elec-
trode erosion and excessive carbon or
other deposits, it should be replaced. Before installing a spark plug, the
spark plug gap should be measured
with a wire thickness gauge and, if
necessary, adjusted to specification.
Clean the surface of the spark plug
gasket and its mating surface, and
then wipe off any grime from the spark
plug threads.
NOTICE
ECA10841
Do not use any tools to remove or in-
stall the spark plug cap, otherwise
the ignition coil coupler may get
damaged. The spark plug cap may
be difficult to remove because the
rubber seal on the end of the cap fits
tightly. To remove the spark plug
cap, simply twist it back and forth
while pulling it out; to install it, twist
it back and forth while pushing it in.
