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.

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.

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.

ECAM1060CAUTION:
The engine oil tank \fust be \billed in
2 steps. First, \bill the engine oil tank
with 1.90 L (2.0 US qt) (1.67 I\fp.qt)
o\b the reco\f\fended engine oil.
Then, start the engine, race it 5 or 6
ti\fes, turn it o\b\b, and then add the
re\fainder o\b the eng\kine oil.
NOTE:
Be sure to wipe off spi\f\fed oi\f on an\b
parts after the engine and exhaust
s\bstem have coo\fed d\fown.
ECA11620CAUTION: In order to prevent clutch slip-
page (since the engine oil also
lubricates the clutch), do not
\fix any che\fical additives. Do
not use oils with a diesel speci-
\bication o\b “CD” or oils o\b a
higher quality than speci\bied. In
addition, do not use oils la-
beled “ENERGY CONSERVING
II” or higher.
Make sure that no \boreign \fa-
terial enters the c\krankcase.
14. Start the engine, and then \fet it id\fe for severa\f minutes whi\fe
checking it for oi\f \feakage. If oi\f is
\feaking, immediate\f\b turn the en-
gine off and check for the \fcause.
15. Turn the engine off, and then check the oi\f \feve\f and correct it if
necessar\b.
16. Insta\f\f the engine guard b\b in- sta\f\fing the screws.\f

Coolant
The coo\fant \feve\f sho\fu\fd be checked
before each ride. In addition, the
coo\fant must be changed at the inter-
va\fs specified in the periodic mainte-
nance and \fubrication \fchart.
EAU20253
To check the coolant level1. P\face the vehic\fe on a \feve\f sur- face and ho\fd it in an upright posi-
tion.
NOTE:
The coo\fant \feve\f must be
checked on a co\fd engine since
the \feve\f varies with engine tem-
perature.
Make sure that the vehic\fe is posi-
tioned straight up when checking
the coo\fant \feve\f. A s\fight ti\ft to the
side can resu\ft in a \ffa\fse reading.
2. Check the coo\fant \feve\f in the coo\fant reservoir.
Reco\f\fended engine \koil:See page 8-1.

the coolant reservoir cap. Nev-
er attempt to remove the radia-
tor cap when the engine is hot.
NOTICE: If coolant is not avail-
able, use distilled water or soft
tap water instead. Do not use
hard water or salt water since it
is harmful to the engine. If wa-
ter has been used instead of
coolant, replace it with coolant
as soon as possible, otherwise
the cooling system will not be
protected against frost and
corrosion. If water has been
added to the coolant, have a
Yamaha dealer check the an-
tifreeze content of the coolant
as soon as possible, otherwise
the effectiveness of the coolant
will be reduced.
