\bse only unleaded gasoline. The use
o\f leaded gasoline will cause severe
damage to internal engine parts,
such as the valves and piston rings,
as well as to the exhaust system.
Your Yamaha en\fine has been \besi\f-
ne\b to use premium unlea\be\b \fasoli-
ne with a research octane number of
95 or hi\fher. If knockin\f (or pin\fin\f)
occurs, use a \fasoline of a \bifferent
bran\b. Use of unlea\be\b fuel will
exten\b spark plu\f life an\b re\buce
maintenance costs.
EAUB1300
Fuel tank breather/over\flow
hose
1. Fuel tank breather/hose
2. Hose clamp
Before operatin\f the motorcycle:
Check the fuel tank breather/over-
flow hose connection.
Check the fuel tank
breather/overflow hose for
cracks or \bama\fe, an\b replace it
if \bama\fe\b.
Make sure that the en\b of the fuel
tank breather/overflow hose is
not blocke\b, an\b clean it if
necessary.
Make sure that the en\b of the fuel
tank breather/overflow hose is
positione\b insi\be of the clamp.
EAU13433
Catalytic converters
This vehicle is equippe\b with catalytic
converters in the exhaust system.
EWA10862
The exhaust system is hot a\fter
operation. 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
system has cooled down be\fo-
re doing any maintenance
work.
Do not allow the engine to idle
more than a \few minutes. Long
idling can cause a build-up o\f
heat.

Periodic inspection\f adjust\bent\f and
lubrication will keep your vehicle in the
safest and \bost efficient condition
possible. Safety is an obligation of the
vehicle owner/operator. The \bost i\b-
portant points of vehicle inspection\f
adjust\bent\f and lubrication are ex-
plained on the following pages.
The intervals given in the periodic
\baintenance and lubrication char t
should be si\bply considered as a gen-
eral guide under nor\bal riding condi-
tions. However\f depending on the
weather\f terrain\f geographical loca-
tion\f and individual use\f the \bainte-
nance intervals \bay need to be short-
ened.
EWA10321
W\fRNING0
Failure to properly maintain the ve-
hicle or performing maintenance
activities incorrectly may increase
your risk of injury or death during
service or while using the vehicle. If
you are not familiar with vehicle
service, have a Yamaha dealer per-
form service.
EAU17391
Owner’s tool kit
1. Owner’s tool kit
The owner’s tool kit is located under
the seat. (See page 4-14).
The service infor\bation included in this
\banual and the tools provided in the
owner’s tool kit are intended to assist
you in the perfor\bance of preventive
\baintenance and \binor repairs. How-
ever\f additional tools such as a torque
wrench \bay be necessary to perfor\b
certain \baintenance work correctly.
TIP
If you do not have the tools or experi-
ence required for a particular job\f have
a Ya\baha dealer perfor\b it for you.

W\fRNING0
Turn off the engine when perform-
ing maintenance unless otherwise
specified.
\f running engine has moving parts
that can catch on body parts or
clothing and electrical parts that
can cause shocks or\M fires.
Running the engine while servicing
can lead to eye injury, burns, fire, or
carbon monoxide poisoning - pos-
sibly leading to death. See page 2-2
for more information about carbon
monoxide.

2. Remove the spark pl\fg as shown\b with the spark pl\fg wrench incl\fd-
ed in the owner’s tool kit.
To check the spark plug 1. Check that the porcelain ins\flator aro\fnd the center electrode of the
spark pl\fg is a medi\fm-to-light
tan (the ideal color when the vehi-
cle is ridden normally).
TIP
If the spark pl\fg shows a distinctly dif-
ferent color\b the engine co\fld be oper-
ating improperly. Do not attempt to di-
agnose s\fch problems yo\frself.
Instead\b have a Yamaha dealer check
the vehicle.
2. Check the spark pl\fg for elec- trode erosion and excessive car-
bon or other deposits\b and re-
place it if necessa\lry.
Specified spark plu\4g:CR7E (NGK)
Spark plug gap:0.7-0.8 mm (0.028-0\l.032 in)
To install the spark plug
1. Meas\fre the spark pl\fg gap with a wire thickness ga\fge and\b if
necessar y\b adj\fst the gap to
specification.
1. Spark pl\fg gap
2. Clean the s\frface of the sparkpl\fg gasket and its mating s\fr-
face\b and then wipe off any grime
from the spark pl\fg threads.
3. Install the spark pl\fg with the spark pl\fg wrench\b and then tight-
en it to the specif\lied torq\fe.
EAU19603
Checking the spark plug
The spark pl\fg is an important engine
component\b which is easy to check.
Since heat and deposits will ca\fse
any spark pl\fg to slowly erode\b the
spark pl\fg sho\fld be removed and
checked in accordance with the peri-
odic maintenance and l\fbrication
chart. In addition\b the condition of the
spark pl\fg can reveal the condition of
the engine.
To remove the spark plug
1. Spark pl\fg cap
2. Spark pl\fg wrench
1. Remove the spark pl\fg cap.

Engine oil and oil filter

The engine oi\f \feve\f shou\f\b be checke\b
before each ri\be. In a\b\bition, the oi\f must
be change\b an\b the oi\f fi\fter e\fement re-
p\face\b at the interva\fs specifie\b in the
perio\bic maintenance an\b \fubrication
chart.
To check the engine oil level1. P\face the vehic\fe on a \feve\f surface an\b ho\f\b it in an upright position.
TIP
Make sure that the vehic\fe is posi-
tione\b straight up when checking the
oi\f \feve\f. A s\fight ti\ft to the si\be can re-
su\ft in a fa\fse rea\bing.
2. Start the engine, warm it up for 10-15 minutes an\b then turn it off.
3. Remove the oi\f fi\f\fer cap, wipe the \bipstick c\fean, insert it back into
the oi\f fi\f\fer ho\fe (without screwing
it in), an\b then remove it again to
check the oi\f \feve\f.
1. Engine oi\f fi\f\fer cap
2. Maximum \feve\f mark
3. Minimum \feve\f mark
TIP
●The engine oi\f tank is \focate\b in-
si\be of the frame.
●The engine oi\f shou\f\b be between
the minimum an\b maximum \feve\f
marks.
Tightening torque:Spark p\fug:12.5 Nm (1.25 m·kg\of, 9.0 ft·\fbf)
TIP
If a torque wrench is not avai\fab\fe
when insta\f\fing a spark p\fug, a goo\b
estimate of the correct torque is 1/4-
1/2 turn past finger tight. However, the
spark p\fug shou\f\b be tightene\b to the
specifie\b torque as s\ooon as possib\fe.
4. Insta\f\f the spark p\fug cap.
