NOTICE
ECA11401
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 system.
TIP
This mark identifies the recom-
mended fuel for this vehicle as
specified by European regulation
(EN228).

Check that gasoli
ne nozzle has thesame identifier when fueling.
Your Yamaha engine has been de-
signed to use premium unleaded gaso-
line with a research octane number of
95 or higher. If knocking (or pinging) oc-
curs, use a gasoline of a different
brand. Use of unleaded fuel will extend
spark plug life and reduce maintenance
costs.
Gasohol
There are two types of gasohol: gaso- hol containing ethanol and that contain-
ing 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.
Recommended fuel:
Premium unleaded gasoline (Gaso-
hol [E10] acceptable)
Fuel tank capacity: 17 L (4.5 US gal, 3.7 Imp.gal)
Fuel reserve amount:
4.0 L (1.06 US gal, 0.88 Imp.gal)

Fuel tank overflow hoseBefore operating the vehicle:
Check the overflow hose connec-
tion and for damage.

Confirm the overflow hose is not
blocked and is routed through the
clamp.
TIPSee page 7-10 for canister information.
EAU13434
Catalytic converterThis model is equipped with a catalytic
converter in the exhaust system.
WARNING
EWA10863
The exhaust system is hot after op-
eration. To prevent a fire hazard or
burns:
Do not park the vehicle near
possible fire hazards such as
grass or other materials that
easily burn.

Park the vehicle in a place
where pedestrians or children
are not likely to touch the hot
exhaust system.

Make sure that the exhaust sys-
tem has cooled down before do-
ing any maintenance work.

Do not allow the engine to idle
more than a few minutes. Long
idling can cause a build-up ofheat.
NOTICE
ECA10702
Use only unleaded gasoline. The use
of leaded gasoline will cause unre- pairable damage to the catalytic
converter.

turn the key counterclockwise.
2. While holding the key in that posi- tion, slide the seat backward and
then lift the rear of the seat up, and
then pull the seat off.
To install the seat 1. Insert the projections into the seat holders as shown. 2. Push the rear of the seat down to
lock it in place.
3. Remove the key.
TIPMake sure that the seat is properly se-cured before riding.

Adjusting the front forkThis model is equipped with adjustable
suspension. The spring preload, re-
bound damping force, and compres-
sion damping force of each leg can be
adjusted.
WARNING
EWA10181
Always adjust both fork legs equal-
ly, otherwise poor handling and lossof stability may result.NOTICE


Use extra care to avoid scratch-
ing the gold-anodized finish
when making suspension ad-
justments.

To avoid damaging the suspen-
sion’s internal mechanisms, do
not attempt to turn beyond themaximum or minimum settings.
Spring preload
To increase the spring preload and
thereby harden the suspension, turn
the adjusting nut on each fork in direc-
tion (a). To decrease the spring preload

Adjusting the shock absorber
assemblyThis model is equipped with adjustable
suspension. The spring preload, re-
bound damping force, fast compres-
sion damping force, and slow
compression damping force can be ad-
justed.NOTICE
ECA10102
To avoid damaging the mechanism,
do not attempt to turn beyond themaximum or minimum settings.
Spring preload
1. Loosen the locknut.
2. To increase the spring preload and thereby harden the suspension,
turn the adjusting ring in direction
(a). To decrease the spring pre-
load and thereby soften the sus-
pension, turn the adjusting ring in
direction (b).
The spring preload setting is deter-
mined by measuring distance A.
The longer distance A is, the high-
er the spring preload; the shorter distance A is, the lower the spring
preload.

ed in the additional tool kit to
make the adjustment.

This shock absorber assembly con-
tains highly pressurized nitrogen
gas. Read and understand the fol-
lowing information before handling
the shock absorber assembly.
Do not tamper with or attempt to
open the cylinder assembly.

Do not subject the shock ab-
sorber assembly to an open
flame or other high heat source.
This may cause the unit to ex-
plode due to excessive gas
pressure.

Do not deform or damage the
cylinder in any way. Cylinder
damage will result in poor
damping performance.

Do not dispose of a damaged or
worn-out shock absorber as-
sembly yourself. Take the shock
absorber assembly to a Yamaha
dealer for any service.

EXUP systemThis model is equipped with Yamaha’s
EXUP (EXhaust Ultimate Power valve)
system. This system boosts engine
power by means of a valve that controls
exhaust flow within the exhaust cham-
ber.NOTICE
ECA15611
The EXUP system has been set and
extensively tested at the Yamaha
factory. Changing these settings
without sufficient technical knowl-
edge may result in poor perfor-mance of or damage to the engine.

Auxiliary DC jackA 12-V accessory connected to the
auxiliary DC jack can be used when the
main switch is on.NOTICE
ECA15432
The accessory connected to the
auxiliary DC jack should not be used
with the engine turned off, and the
load must never exceed 12 W (1.0 A),
otherwise the fuse may blow or thebattery may discharge.
To use the auxiliary DC jack 1. Turn the main switch off.
2. Remove the auxiliary DC jack cap.

EAU15306
SidestandThe sidestand is located on the left side
of the frame. Raise the sidestand or
lower it with your foot while holding the
vehicle upright.TIPThe built-in sidestand switch is part of
the ignition circuit cut-off system, which
cuts the ignition in certain situations.
(See the following section for an expla-
nation of the ignition circuit cut-off sys-tem.)
WARNING
EWA10242
The vehicle must not be ridden with
the sidestand down, or if the sides-
tand cannot be properly moved up
(or does not stay up), otherwise the
sidestand could contact the ground
and distract the operator, resulting
in a possible loss of control.
Yamaha’s ignition circuit cut-off
system has been designed to assist
the operator in fulfilling the respon-
sibility of raising the sidestand be-
fore starting off. Therefore, check
this system regularly and have a Yamaha dealer repair it if it does not
function properly.

Ignition circuit cut-off systemThis system prevents in-gear engine
starts unless the clutch lever is pulled
and the sidestand is up. Also, it will stop
the running engine should the sides-
tand be lowered while the transmission
is in gear.
Periodically check this system via the
following procedure.TIP
This check is most reliable if per-
formed with a warmed-up engine.
