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

Changing the brake fluid
Have a Yamaha dealer \fhange the
\brake fluid at the intervals spe\fified in
the TIP after the periodi\f maintenan\fe
and lu\bri\fation \fhart. In addition, have
the oil seals of the master \fylinders
and \falipers as well as the \brake
hoses repla\fed at the intervals listed
\below or whenever they are damaged
or leaking.
●Oil seals: Repla\fe ever y two
years.
●Brake hoses: Repla\fe every four
years.

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)
