1operator and may limit control
ability, therefore, such accesso-
ries are not recommended.
 Use caution when adding electri-
cal accessories. If electrical ac-
cessories exceed the capacity of
the motorcycle’s electrical sys-
tem, an electric failure could re-
sult, which could cause a
dangerous loss of lights or engine
power.
Aftermarket Tires an d Rims
The tires and rims that came with your
motorcycle were designed to match
the performance capabilities and to
provide the best combination of han-
dling, braking, and comfort. Other
tires, rims, sizes, and combinations
may not be appropriate. Refer to page
6-20 for tire specifications and more in-
formation on replacing your tires.
Transportin g the Motorcycle
Be sure to observe following instruc-
tions before transporting the motorcy-
cle in another vehicle.  Remove all loose items from the
motorcycle. 
Check that the fuel cock (if
equipped) is in the “OFF” position
and that there are no fuel leaks.
 Point the front wheel straight
ahead on the trailer or in the truck
bed, and choke it in a rail to pre-
vent movement.
 Shift the transmission in gear (for
models with a manual transmis-
sion).
 Secure the motorcycle with tie-
downs or suitable straps that are
attached to solid parts of the mo-
torcycle, such as the frame or up-
per front fork triple clamp (and not,
for example, to rubber-mounted
handlebars or turn signals, or
parts that could break). Choose
the location for the straps carefully
so the straps will not rub against
painted surfaces during transport.
 The suspension should be com-
pressed somewhat by the tie-
downs, if possible, so that the mo-
torcycle will not bounce exces-
sively during transport.

Immobilizer systemThis vehicle is equipped with an immo-
bilizer system to help prevent theft by
re-registering codes in the standard
keys. This system consists of the fol-
lowing:
 a code re-registering key (with a
red bow)
 two standard keys (with a black
bow) that can be re-registered
with new codes
 a transponder (which is installed in
the code re-registering key)
 an immobilizer unit
 an ECU 
an immobilizer system indicator
light (See page 3-7.)
The key with the red bow is used to
register codes in each standard key.
Since re-registering is a difficult pro-
cess, take the vehicle along with all
three keys to a Yamaha dealer to have
them re-registered. Do not use the key
with the red bow for driving. It should
only be used for re-registering the
standard keys. Always use a standard
key for driving.
NOTICE
ECA11822
 DO NOT LOSE THE CODE RE-
REGISTERING KEY! CONTACT
YOUR DEALER IMMEDIATELY
IF IT IS LOST! If the co de re-re g-
isterin g key is lost, reg istering
new co des in the stan dar d keys
is impossib le. The stan dar d
keys can still be used to start
the vehicle, however if cod e re-
re gisterin g is require d (i.e., if a
new stan dar d key is mad e or all
keys are lost) the entire immo bi-
lizer system must be replaced .
Therefore, it is hi ghly recom- men
ded to use either stan dar d
key an d keep the co de re-reg is-
tering key in a safe place.
 Do not su bmerse any key in wa-
ter.
 Do not expose any key to exces-
sively hi gh temperatures.
 Do not place any key close to
ma gnets (this inclu des, but not
limite d to, pro ducts such as
speakers, etc.).
 Do n

ot place items that transmit
electrical si gnals close to any
key.
 Do not place heavy items on any
key.
 Do not grin d any key or alter its
shape.
 Do not d isassemble the plastic
part of any key.
 Do not put two keys of any im-
mo bilizer system on the same
key rin g.
 Keep the stan dar d keys as well
as keys of other immo bilizer
systems away from this vehi-
cle’s co de re-reg istering key.

WARNING
EWA15152
Gasoline is poisonous an d can
cause injury or d eath. Handle gaso-
line with care. Never siphon gasoline
b y mouth. If you shoul d swallow
some gasoline or inhale a lot of gas-
oline vapor, or get some g asoline in
your eyes, see your doctor imme di- ately. If g
asoline spills on your skin,
wash with soap an d water. If gaso-
line spills on your clothin g, chan ge
your clothes.
EAU54601
NOTICE
ECA11401
Use only unlea ded g asoline. The use
of lead ed g asoline will cause severe
d amag e to internal en gine parts,
such as the valves an d piston rin gs,
as well as to the exhaust system.Your Yamaha engine has been de-
signed to use premium unleaded gas-
oline with a research octane number 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 mainte-
nance costs.
Gasohol
There are two types of gasohol: gaso-
hol containing ethanol and that con-
taining methanol. Gasohol containing
ethanol can be used if the ethanol con-
tent does not exceed 10% (E10). Gas-
ohol containing methanol is not
recommended by Yamaha because it
can cause damage to the fuel system
or vehicle performance problems.

Checking an d lu bricatin g the
throttle grip an d ca bleThe operation of the throttle grip
should be checked before each ride. In
addition, the cable should be lubricat-
ed by a Yamaha dealer at the intervals
specified in the periodic maintenance
chart.
The throttle cable is equipped with a
rubber cover. Make sure that the cover
is securely installed. Even though the
cover is installed correctly, it does not
completely protect the cable from wa-
ter entry. Therefore, use care not to
pour water directly onto the cover or
cable when washing the vehicle. If the
cable or cover becomes dirty, wipe
clean with a moist cloth.
