Tips for re
ducin g fuel con-
sumptionFuel consumption depends largely on
your riding style. Consider the follow-
ing 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 traf-
fic lights or at railroad crossings).
EAUW4891
Parkin g When parking, turn off the Stop and

After turning off the main switch, be
sure to turn off the smart key and take
it with you.

• This model’s engine air filter is equipped with a disposable oil-coated paper element, which must not be cleaned with compressed air to avoid damaging it.
• The engine air filter element needs to be replaced and the V-belt air filter element needs to be serviced more fre- quently when riding in unusually wet or dusty areas.21 *Final transmission

Checkin g the spark plugThe spark plug is an important engine
component, which should be checked
periodically, preferably by a Yamaha
dealer. Since heat and deposits will
cause any spark plug to slowly erode,
it should be removed and checked in
accordance with the periodic mainte-
nance and lubrication chart. In addi-
tion, 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 deal-
er check the vehicle.
If the 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.
TIPIf a torque wrench is not available
when installing a spark plug, a good
estimate of the correct torque is 1/4–
1/2 turn past finger tight. However, the
spark plug should be tightened to the
specified torque as soon as possible.

CanisterThis model is equipped with a canister
to prevent the discharging of fuel vapor
into the atmosphere. Before operating
this vehicle, make sure to check the
following:
 Check each hose connection. 
Check each hose and canister for
cracks or damage. Replace if
damaged.
 Make sure that the canister
breather is not blocked, and if
necessary, clean it.
EAU66995
Engine oil an d oil strainerThe engine oil level should be checked
before each ride. In addition, the oil
must be changed and the oil strainer
cleaned at the intervals specified in the
periodic maintenance and lubrication
chart.
To check the en gine oil level
1. Place the vehicle on the center- stand. A slight tilt to the side can
result in a false reading.
2. Start the engine, warm it up for several minutes, and then turn it
off.
3. Wait a few minutes until the oil set- tles, remove the engine oil filler
cap, wipe the engine oil dipstick
clean, insert it back into the oil fill-
er hole (without screwing it in), and
then remove it again to check the
oil level. WARNING! The muffler
an d muffler protector become
very hot d uring use. To avoi d
possi ble burns, let the muffler
an d protector cool before re-
movin g the oil filler cap.

TIP The coolant level must be
checked on a cold engine since
the level varies with engine tem-
perature.
 Make sure that the vehicle is posi-
tioned straight up when checking
the coolant level. A slight tilt to the
side can result in a false reading.2. Check the coolant level in the
coolant reservoir.TIPThe coolant should be between the mi-
nimum and maximum level marks.
3. If the coolant is at or below the mi-nimum level mark, have a Yamaha
dealer add coolant to the reser-
voir.
EAU33032
Chan gin g the coolant
The coolant must be changed at the in-
tervals specified in the periodic main-
tenance and lubrication chart. Have a
Yamaha dealer change the coolant.
WARNING! Never attempt to remove the ra diator cap when the en gine is
hot.

Air filter an

placed and the V-belt case air filter el-
ement should be cleaned at the
intervals specified in the periodic main-
tenance and lubrication chart. Service
the air filter elements more frequently if
you are riding in unusually wet or dusty
areas. The air filter check hose and V-
belt case air filter check hose must be
frequently checked and cleaned if nec-
essary.

Emer gency mo de When the smart key is lost or dam-
aged, or its battery has discharged, the
vehicle can still be turned on and the
engine started. You will need the smart
key system identification number.
To operate the vehicle in emer gency
mo de
1. Stop the vehicle in a safe place and turn the main switch to “OFF”.
2. Push the main switch knob for 5 seconds until the smart key sys-
tem indicator light flashes once,
then release it. Repeat two more
times. The smart key system indi-
cator light will come on for three
seconds to indicate the transition
to emergency mode. 3. After the smart key system indica-
tor light goes off, input the identifi-
cation number as follows. 4. Inputting the identification number
is done by counting the number of
flashes of the smart key system in-
dicator light.
For example, if the identification
number is 123456:
Push and hold the knob.
↓
The smart key system indicator
light will start to flash.
↓
Release the knob after the smart
key system indicator light flashes
once.
↓
The first digit of the identification
number has been set as “1”.
↓
Push and hold the knob again.

Release the knob after the smart
key system indicator light flashes
twice.
↓
The second digit has been set as
“2”.
↓
Repeat the above procedure until
all digits of the identification num-
ber have been set. The smart key
system indicator light will flash for
10 seconds if the correct identifi-
cation number was entered.
TIPWhen one of the following situations
applies, emergency mode will be ter-
minated and the smart key system in-
dicator light will flash quickly for 3
seconds. In this case, start over again
from step 2. 
When there are no knob opera-
tions for 10 seconds during the
identification number input pro-
cess.
 When the smart key system indi-
cator light is allowed to flash nine
or more times.
 The identification number is not
entered correctly.
5. While the smart key system indi-
cator light is on, push the knob
once more to complete emergen-
cy mode access. The smart key
indicator light will go off and then
come back on for approximately 4
seconds.
6. While the smart key system indi- cator light is on, turn the main
switch to “ON”. The vehicle can
now be operated normally.
