operator 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.

EAU11022Turn si gnal in dicator li ght “ ”
This indicator light flashes when a turn
signal light is flashing.
EAU11061Neutral in dicator li ght “ ”
This indicator light comes on when the
transmission is in the neutral position.
EAU11081Hi gh beam in dicator li ght “ ”
This indicator light comes on when the
high beam of the headlight is switched
on.
EAU11256Oil level warnin g li ght “ ”
This warning light comes on if the en-
gine oil level is low. The electrical circuit of the warning
light can be checked by turning the key
to “ON”. The warning light should
come on for a few seconds and then
go off.
If the warning light does not come on
initially when the key is turned to “ON”,
or if the warning light remains on after
confirming that the oil level is correct
(see page 6-11), have a Yamaha dealer
check the vehicle.
TIP

Even if the oil level is sufficient, the
warning light may flicker when rid-
ing on a slope or during sudden
acceleration or deceleration, but
this is not a malfunction.
 This model is equipped with a self-
diagnosis device for the oil level
detection circuit. If a problem is
detected in the oil level detection
circuit, the oil level warning light
will flash repeatedly. If this occurs,
have a Yamaha dealer check the
vehicle.
EAU72930Coolant temperature warnin g
li g ht “ ”
This warning light comes on if the en-
gine overheats. If this occurs, reduce
the load on the engine immediately. If
message “HI” flashes in the coolant
temperature display, stop the vehicle,
then stop the engine and let the engine
cool.
The electrical circuit of the warning
light can be checked by turning the key
to “ON”. The warning light should
come on for a few seconds, and then
go off.

Ig nition circuit cut-off system
The ignition circuit cut-off system
(comprising the sidestand switch,
clutch switch and neutral switch) has
the following functions.
 It prevents starting when the
transmission is in gear and the
sidestand is up, but the clutch le-
ver is not pulled.
 It prevents starting when the
transmission is in gear and the
clutch lever is pulled, but the side-
stand is still down.
 It cuts the running engine when
the transmission is in gear and the
sidestand is moved down.
Periodically check the operation of the
ignition circuit cut-off system accord-
ing to the following procedure.

Drive chain slack
The drive chain slack should be
checked before each ride and adjusted
if necessary.
EAU59593To check the d rive chain slack
1. Place the motorcycle on the cen- terstand.
2. Shift the transmission into the neutral position.
3. Push on the drive chain at the cen- ter point between the drive axle
and the rear wheel axle with a
force of 50 N (5.0 kgf, 11 lbf).
4. Measure the drive chain slack as shown.
5. If the drive chain slack is incorrect, adjust it as follows.
EAU53951To a djust the d rive chain slack
Consult a Yamaha dealer before ad-
justing the drive chain slack. 1. Take the motorcycle off the cen- terstand, and then put the side-
stand down. 2. Loosen the locknut at each end of
the swingarm, and then loosen the
axle nut.
3. Place the motorcycle on the cen- terstand.
4. To tighten the drive chain, turn the drive chain slack adjusting nut at
each end of the swingarm in direc-
tion (a). To loosen the drive chain,
turn the adjusting nut at each end
of the swingarm in direction (b),
and then push the rear wheel for-
ward. NOTICE: Improper drive
chain slack will overloa d the en-
g ine as well as other vital parts
of the motorcycle an d can lead
to chain slippag e or breakag e.
To prevent this from occurrin g,
keep the d rive chain slack with-
in the specified limits.
