12 MENT.
Do not run engine indoors. Even if
you try to ventilate engine exhaust
with fans or open windows and
doors, carbon monoxide can rap-
idly reach dangerous levels.
Do not run engine in poorly venti-
lated or partially enclosed areas
such as barns, garages, or car-
ports.
Do not run engine outdoors where
engine exhaust can be drawn into
a building through openings such
as windows and doors.
Loading
Adding accessories or cargo to your
motorcycle can adversely affect stabili-
ty and handling if the weight distribution
of the motorcycle is changed. To avoid
the possibility of an accident, use ex-
treme caution when adding cargo or
accessories to your motorcycle. Use
extra care when riding a motorcycle
that has added cargo or accessories.
Here, along with the information about
accessories below, are some general
guidelines to follow if loading cargo to
your motorcycle: The total weight of the operator, pas-
senger, accessories and cargo must
not exceed the maximum load limit.
Operation of an overloaded vehicle
could cause an accident.
When loading within this weight limit,
keep the following in mind:
Cargo and accessory weight
should be kept as low and close to
the motorcycle as possible. Se-
curely pack your heaviest items as
close to the center of the vehicle as
possible and make sure to distrib-
ute the weight as evenly as possi-
ble on both sides of the motorcycle
to minimize imbalance or instabili-
ty.
Shifting weights can create a sud-
den imbalance. Make sure that ac-
cessories and cargo are securely
attached to the motorcycle before
riding. Check accessory mounts
and cargo restraints frequently.
Properly adjust the suspension
for your load (suspension-ad- justable models only), and
check the condition and pres-
sure of your tires.
Never attach any large or heavy items to the handlebar, front
fork, or front fender. These
items, including such cargo as
sleeping bags, duffel bags, or
tents, can create unstable han-
dling or a slow steering re-
sponse.
This vehicle is not designed to
pull a trailer or to be attached to
a sidecar.
Genuine Yamaha Accessories
Choosing accessories for your vehicle
is an important decision. Genuine
Yamaha accessories, which are avail-
able only from a Yamaha dealer, have
been designed, tested, and approved
by Yamaha for use on your vehicle.
Many companies with no connection to
Yamaha manufacture parts and acces-
sories or offer other modifications for
Yamaha vehicles. Yamaha is not in a
position to test the products that these
aftermarket companies produce.
Therefore, Yamaha can neither en-

NOTICE
ECA22950
Even when using LCS, the clutch le-
ver must be released gradually toavoid clutch damage.TIPLCS is intended for track use only.
QSS
The quick shift system allows for clutch
lever-less, electronically-assisted shift-
ing. When the sensor on the shift rod
detects the appropriate motion in the
shift pedal, engine power output is mo-
mentarily adjusted to allow for the gear
change to occur.
QSS does not operate when the clutch
lever is pulled, therefore normal shifting
can be done even when QSS is set to
on. Check the QS indicator for current
status and usability information. Upshifting conditions
Vehicle speed of at least 20 km/h
(12 mi/h)
Engine speed of at least 2200 r/min
Accelerating (open throttle)
Downshifting conditions
Vehicle speed of at least 20 km/h
(12 mi/h)
Engine speed of at least 2000 r/min
Engine speed sufficiently away
from red zone
Decelerating and throttle ful-
ly-closed
TIP
QS and QS can be individu-
ally set.
Shifting into or out of neutral mustbe done using the clutch lever.
LIF
The lift control system reduces the rate
at which the front wheel will continue to
rise during extreme acceleration, such
as during starts or out-of-corner exits.
When front-wheel lift is detected, en-
gine power is regulated to slow front-wheel lift while still providing good
acceleration.

Immobilizer system indicator light
“”
When the key is turned to “OFF” and 30
seconds have passed, the indicator
light will flash steadily to indicate the im-
mobilizer system is enabled. After 24
hours have passed, the indicator light
will stop flashing, however the immobi-
lizer system is still enabled.
The electrical circuit of the indicator
light can be checked by turning the key
to “ON”. The indicator light should
come on for a few seconds, and then
go off.
If the indicator light does not come on
initially when the key is turned to “ON”,
if the indicator light remains on, or if the
indicator light flashes in a pattern (if a
problem is detected in the immobilizer
system, the immobili zer system indica-
tor light will flash in a pattern), have a
Yamaha dealer check the vehicle.TIPIf the immobilizer system indicator light
flashes in the pattern, slowly 5 times
then quickly 2 times, this could be
caused by transponder interference. If
this occurs, try the following.
1. Make sure there are no other im- mobilizer keys close to the main
switch. Other immobilizer system
keys may cause signal interfer-
ence and prevent the engine from
starting.
2. Use the code re-registering key to start the engine.
3. If the engine starts, turn it off, and try starting the engine with the
standard keys.
4. If one or both of the standard keys do not start the engine, take the
vehicle and all 3 keys to a Yamaha
dealer to have the standard keys
re-registered.
