PERIODIC MAINTENANCE AND MINOR REPAIR

6 Clutch
Insufficient brake or clutch fluid may al-
low air to enter the brake or clutch sys-
tems, possibly causing them to become
ineffective.
NOTE:The rear brake fluid reservoir is locatedunder the rider seat. (See page 3-15.)
Before riding, check that the brake and
clutch fluids are above the minimum
level marks and replenish if necessary.
A low brake or clutch fluid level may in-
dicate brake or clutch system leakage
and/or worn brake pads. If the brake or
clutch levels are low, be sure to check
the brake or clutch systems for leakage
and the brake pads for wear.Observe these precautions:


When checking the brake and
clutch fluid levels, make sure that
the top of each reservoir is level.


Use only the recommended quality
brake fluid, otherwise the rubber
seals may deteriorate, causing
leakage and poor braking or clutch
performance.


Refill with the same type of brake
fluid. Mixing fluids may result in a
harmful chemical reaction and
lead to poor braking or clutch per-
formance.


Be careful that water does not en-
ter the brake or clutch fluid reser-
voir when refilling. Water will
significantly lower the boiling point
of the fluid and may result in vapor
lock.


Brake fluid may deteriorate paint-
ed surfaces or plastic parts. Al-
ways clean up spilled fluid
immediately.


As the brake pads wear, it is nor-
mal for the brake fluid level to grad-
ually go down. However, if the
brake fluid level goes down sud-
denly, have a Yamaha dealer
check the cause.

Changing the brake and
clutch fluids Have a Yamaha dealer change the
brake and clutch fluids at the intervals
specified in the NOTE after the periodic
maintenance and lubrication chart. In
addition, have the oil seals of the brake
and clutch master cylinders and cali-
pers as well as the brake and clutch
hoses replaced at the intervals listed
below or whenever they are damaged
or leaking.

Oil seals: Replace every two
years.


Brake and clutch hoses: Replace
every four years.

Drive belt slack The drive belt slack should be checked
and adjusted at the intervals specified
in the periodic maintenance and lubri-
cation chart.
EAU38410
To check the drive belt slack
1. Place the vehicle on the sidestand.
2. Note the current position of the
drive belt using the marks near the
drive belt check hole.NOTE:The marks near the drive belt checkhole are 5.0 mm (0.2 in) apart.3. Note the position of the drive belt
with a force of 45 N (4.5 kgf, 10 lbf)
applied to the belt with a belt ten-
sion gauge as shown.
NOTE:A belt tension gauge is available at aYamaha dealer.
4. Calculate the drive belt slack by
subtracting the measurement not-
ed in step 2 from the measurement
noted in step 3.
5. If the drive belt slack is incorrect,
have a Yamaha dealer adjust it.
