Tachometer
1. Tachometer
2. Red zone
The tachometer allows the rider to
monitor the engine speed and keep it
within the ideal power range.
When the key is turned to "ON", the
tachometer needle will sweep once
across the r/min range and then return
to zero r/min in order to test the elec-
trical circuit.
ECA10030CAUTION:
Do not operate the engine in the
tachometer red zone.
Red zone: 7,500 r/min and above.

Tripmeter and tachometer modes
1. “SELECT” button
2. “RESET” button
Pushing the "SELECT" button switch-
es the display between the tripmeter
modes "TRIP 1" and "TRIP 2" in the
following order:
TRIP 1
6TRIP 2 6TRIP 1
When the fuel amount in the fuel tank
decreases to 6.7 L (1.77 US gal) (1.47
Imp.gal), the bottom segment of the
fuel meter will start flashing, and the
tripmeter display will automatically
change to the fuel reserve tripmeter
mode “F-TRIP” and start counting the
distance traveled from that point. In
that case, pushing the "SELECT" but-

ton switches the display between the
various tripmeter modes in the follow-
ing order:
F-TRIP
6TRIP 1 6TRIP 2 6F-TRIP
To reset a tripmeter, select it by push-
ing the "SELECT" button, and then
push the "RESET" button for at least
four seconds. If you do not reset the
fuel reserve tripmeter manually, it will
reset itself automatically and the dis-
play will return to the prior mode after
refueling and traveling 5 km (3 mi).

in the fuel tank. When the key is turned
to "ON", all of the display segments of
the fuel meter will appear one after the
other and then disappear in order to
test the electrical circuit. The display
segments of the fuel meter disappear
towards "E" (Empty) as the fuel level
decreases. When only one segment is
left near "E" (Empty), refuel as soon
as possible.
NOTE:
This fuel meter is equipped with a self-
diagnosis system. If the electrical circuit
is defective, all the segments will start
flashing. If this occurs, have a Yamaha
dealer check the electrical circuit.
Self-diagnosis devices
1. Engine trouble warning light “ U”
2. Immobilizer system indicator light “ ”
This model is equipped with a self-di-
agnosis device for various electrical
circuits.
If any of those circuits are defective,
the engine trouble warning light will
start flashing. If this occurs, have a
Yamaha dealer check the vehicle.
This model is also equipped with a
self-diagnosis device for the immobi-
lizer system.
If any of the immobilizer system cir-
cuits are defective, the immobilizer
system indicator light will start flash-
ing.
If this occurs, have a Yamaha dealer
check the vehicle.

NOTE:
If the indicator light slowly flashes five
times, and then quickly flashes two
times repeatedly, this error could be
caused by transponder interference. If
this occurs, try the following. 1. Use the code re-registering key to start the engine.
NOTE:
Make sure there are no other immobi-
lizer keys close to the main switch, and
do not keep more than one immobiliz-
er key on the same key ring! Immobi-
lizer system keys may cause signal in-
terference, which may prevent the
engine from starting.
2. If the engine starts, turn it off, and try starting the engine with the
standard keys.
3. If one or both of the standard keys do not start the engine, take the
vehicle, the code re-registering
key and both standard keys to a
Yamaha dealer and have the
standard keys re-registered. If the immobilizer system indicator
light continues to flash, have a Yama-
ha dealer check the vehicle.

Fuel tank breather hose
1. Fuel tank breather hose
2. Clamp
Before operating the motorcycle:
●Check the fuel tank breather hose
connection.
●Check the fuel tank breather hose
for cracks or damage, and replace
it if damaged.
●Make sure that the fuel tank
breather hose is not blocked, and
clean it if necessary.

ECA11400CAUTION:
Use only unleaded gasoline. The
use of leaded gasoline will cause
severe damage to internal engine
parts, such as the valves and piston
rings, as well as to the exhaust sys-
tem.
Your Yamaha engine has been de-
signed to use premium unleaded
gasoline with a research octane num-
ber of 95 or higher. If knocking (or
pinging) occurs, use a gasoline of a
different brand. Use of unleaded fuel
will extend spark plug life and reduce
maintenance costs.
EAU13431
Catalytic converter
This model is equipped with a catalyt-
ic converter in the exhaust system.
EWA10860
WARNING0
The exhaust system is hot after op-
eration. Make sure that the exhaust
system has cooled down before
doing any maintenance work.

WARNING0
The vehicle must not be ridden
with the sidestand down, or if the
sidestand cannot be properly
moved up (or does not stay up),
otherwise the sidestand could con-
tact the ground and distract the
operator, resulting in a possible
loss of control. Yamaha’s ignition
circuit cut-off system has been de-
signed to assist the operator in ful-
filling the responsibility of raising
the sidestand before starting off.
Therefore, check this system regu-
larly as described below and have
a Yamaha dealer repair it if it does
not function properly.

EAU15301
Sidestand
1. Sidestand
The sidestand is located on the left
side of the frame. Raise the sidestand
or lower it with your foot while holding
the motorcycle upright.
NOTE:
The built-in sidestand switch is part of
the ignition circuit cut-off system,
which cuts the ignition in certain situa-
tions. (See further down for an expla-
nation of the ignition circuit cut-off sys-
tem.)
