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.
Oil quantity: Without oi\f fi\fter e\f\fement
rep\facement:2.50 L (2.64 US qt) (2.19 I\fmp.qt)

Insufficient brake fluid \fay allow air to
enter t\be brake syste\f, possibly caus-
ing it to beco\fe ine\dffective.
Before riding, c\beck t\bat t\be brake flu-
id is above t\be \fini\fu\f level \fark
and replenis\b if ne\dcessary.
A low brake fluid level \fay indicate
worn brake pads and/or brake syste\f
leakage. If t\be brake fluid level is low,
be sure to c\beck t\be brake pads for
wear and t\be brake syste\f for leak-
age.
Observe t\bese precautions\d:
●W\ben c\becking t\be fluid level,
\fake sure t\bat t\be top of t\be
brake fluid reservoir is level.
●Use only t\be reco\f\fended qual-
ity brake fluid, ot\berwise t\be rub-
ber seals \fay deteriorate, caus-
ing leakage and poor braking
perfor\fance.
●Refill wit\b t\be sa\fe type of brake
fluid. Mixing fluids \fay result in a
\bar\fful c\be\fical reaction and
lead to poor braking perfor\fance.
●Be careful t\bat water does not en-
ter t\be brake fluid reservoir w\ben
refilling. Water will significantly
lower t\be boiling point of t\be fluid
and \fay result in vapor lock.
●Brake fluid \fay deteriorate paint-
ed surfaces or plastic parts. Al-
ways clean up spilled fluid i\f\fe-
diately.
●As t\be brake pads wear, it is nor-
\fal for t\be brake fluid level to
gradually go down. However, if
t\be brake fluid level goes down
suddenly, \bave a Ya\fa\ba dealer
c\beck t\be cause.
Recommended brake f\4luid: DOT 4

Drive chain slack
The drive \fhain sla\fk should \be
\fhe\fked \before ea\fh ride and adjusted
if ne\fessary.
EAU22783
To check the drive chain slack
1. Drive \fhain sla\fk
1. Pla\fe the motor\fy\fle on the side-stand.
TIP
When \fhe\fking and adjusting the dri-
ve \fhain sla\fk, there should \be no
weight on the motor\fy\fl\re.
2. Shift the transmission into theneutral position.
3. Move the rear wheel \by pushing the motor\fy\fle to lo\fate the tight-
est portion of the drive \fhain, and
then measure the drive \fhain
sla\fk as shown.
4. If the drive \fhain sla\fk is in\for- re\ft, adjust it as follows.
TIP
When \fhe\fking the drive \fhain sla\fk,
the \fhain tensioner should not \be
tou\fhing the drive \fhain.
Drive chain slack:50.0-60.0 mm (1.96\r-2.36 in)

Checking the front fork
The condition and o\feration of the
front fork \bust be checked as follows
at the inter vals s\fecified in the
\feriodic \baintenance and lubrication
chart.
To check the condition
Check the inner tubes for scratches,
da\bage and excessive oil leakage.
To check the operation 1. Place the \botorcycle on a level surface and hold it in an u\fright
\fosition. WARNING! To avoid in-
jury, securely support the vehi-
cle so there is no danger of it
falling over.
2. While a\f\flying the front brake, \fush down hard on the handle-
bars several ti\bes to check if the
front fork co\b\fresses and re-
bounds s\boothly.
