wash with soap and water. If gaso-
line spills on your clothing, change

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: 18 L (4.8 US gal, 4.0 Imp.gal)
Fuel reserve amount:
2.6 L (0.69 US gal, 0.57 Imp.gal)

Fuel tank overflow hoseTIPSee page 6-11 for breather information.
Before operating the motorcycle:
Check the fuel tank overflow hose
connection.

Check the fuel tank overflow hose
for cracks or damage, and replace
it if necessary.

Make sure that the end of the fuel
tank overflow hose is not blocked,
and clean it if necessary.

Make sure that the fuel tank over-
flow hose is routed through the
clamp.
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.

Adjusting the headlight
beamsThe headlight beam adjusting knobs
are used to raise or lower the height of
the headlight beams. It may be neces-
sary to adjust the headlight beams to
increase visibility and help prevent
blinding oncoming drivers when carry-
ing more or less load than usual. Obey
local laws and regulations when adjust-
ing the headlights.
To raise the headlight beams, turn the
knobs in direction (a). To lower the
headlight beams, turn the knobs in di-
rection (b).

Handlebar position The handlebar can be adjusted to one
of two positions to suit the rider’s pref-
erence. Have a Yamaha dealer adjust
the position of the handlebar.
EAU62451
Adjusting the front fork
WARNING
EWA14671
Always adjust the spring preload on
both fork legs equally, otherwise
poor handling and loss of stabilitymay result.
Each front fork leg is equipped with a
spring preload adjusting bolt. The right
front fork leg is equipped with a re-
bound damping force adjusting screw.NOTICE
ECA10102
To avoid damaging the mechanism,
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 bolt on each fork leg in di-
rection (a). To decrease the spring pre-
load and thereby soften the
suspension, turn the adjusting bolt on
each fork leg in direction (b).

The spring preload setting is deter-
mined by measuring distance A, shown
in the illustration. The shorter distance
A is, the higher the spring preload; the
longer distance A is, the lower the
spring preload.
Rebound damping force
The rebound damping force is adjusted
on the right front fork leg only.
To increase the rebound damping force
and thereby harden the rebound damp-
ing, turn the adjusting screw in direction
(a). To decrease the rebound damping
force and thereby soften the rebound
damping, turn the adjusting screw in di-
rection (b).
TIP
Although the total number of clicks
of a damping force adjusting
mechanism may not exactly match
the above specifications due to
small differences in production, the
actual number of clicks always
represents the entire adjusting
range. To obtain a precise adjust-
ment, check the number of clicks
of each damping force adjusting
mechanism and to modify the
specifications as necessary.

When turning a damping force ad-
juster in direction (a), the 0 click
position and the 1 click positionmay be the same.
