Periodic maintenance and lubrication chart
NOTE:_

The annual checks must be performed every year, except if a kilometer-based maintenance is performed instead.


From 50,000 km, repeat the maintenance intervals starting from 10,000 km.


Items marked with an asterisk should be performed by a Yamaha dealer as they require special tools, data and techni-
cal skills.

Checking the front and rear
brake pads The front and rear brake pads must be
checked for wear at the intervals spec-
ified in the periodic maintenance and
lubrication chart.
EAU00725
Front brake pads
Each front brake pad is provided with a
wear indicator groove, which allows
you to check the brake pad wear with-
out having to disassemble the brake.
To check the brake pad wear, check
the wear indicator groove. If a brake
pad has worn to the point that the wear
indicator groove has almost disap-
peared, have a Yamaha dealer replace
the brake pads as a set.
EAU04396
Rear brake pads
Each rear brake pad is provided with a
wear indicator groove, which allows
you to check the brake pad wear with-
out having to disassemble the brake.
Check the brake pad wear as follows.
1. Remove the brake caliper bolt,
and then tilt the caliper forward to
inspect the wear indicator groove.
If a brake pad has worn to the
point that the wear indicator
groove has almost disappeared,
have a Yamaha dealer replace the
brake pads as a set.

then tighten it to the specified
torque.
EAU03294
Checking the brake fluid level Insufficient brake fluid may allow air to
enter the brake system, possibly caus-
ing it to become ineffective.
Before riding, check that the brake fluid
is above the minimum level mark and
replenish if necessary. A low brake flu-
id level may indicate worn brake pads
and/or brake system leakage. If the
brake level is low, be sure to check the
brake pads for wear and the brake sys-
tem for leakage.Observe these precautions:


When checking the fluid level,
make sure that the top of the brake
fluid reservoir is level.


Use only the recommended quali-
ty brake fluid, otherwise the rubber
seals may deteriorate, causing
leakage and poor braking perfor-
mance.


Refill with the same type of brake
fluid. Mixing fluids may result in a
harmful chemical reaction and
lead to poor braking performance.

Be careful that water does not en-
ter the brake fluid reservoir 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
gradually go down. However, if the
brake fluid level goes down sud-
denly, have a Yamaha dealer
check the cause.
EAU03976
Changing the brake fluid Have a Yamaha dealer change the
brake fluid at the intervals specified in
the NOTE after the periodic mainte-
nance and lubrication chart. In addition,
have the oil seals of the master cylin-
ders and calipers as well as the brake
hoses replaced at the intervals listed
below or whenever they are damaged
or leaking.

Oil seals: Replace every two
years.


Brake hoses: Replace every four
years.
EAU00744
Drive chain slack The drive chain slack should be
checked before each ride and adjusted
if necessary.
To check the drive chain slack
1. Place the motorcycle on a level
surface and hold it in an upright
position.NOTE:_ When checking and adjusting the drive
chain slack, the motorcycle should be
positioned straight up and there should
be no weight on it. _

according to the procedure on
page 6-39.
3. Remove the brake hose holder on
each side by removing the bolt
and nut.
4. Remove the brake caliper on each
side by removing the bolts.5. Remove the axle bolt, pull the
wheel axle out, and then remove
the wheel.

To install the front wheel
1. Lift the wheel up between the fork
legs.
2. Insert the wheel axle.
3. Lower the front wheel so that it is
on the ground.
4. Install the brake calipers by install-
ing the bolts, and then tightening
them to the specified torque.NOTE:_ Make sure that there is enough space
between the brake pads before install-
ing the brake calipers onto the brake
discs. _5. Install the brake hose holders by
installing the bolts and nuts.6. Secure the wheel axle by installing
the axle bolt, and then tightening it
to the specified torque.
NOTE:_ While tightening the axle bolt, hold the
wheel axle with a 19-mm hexagon
wrench to keep it from turning. _7. Tighten wheel axle pinch bolts A
and B to the specified torque.8. Tap the outer side of the right fork
leg with a rubber mallet to align it
with the end of the wheel axle.
9. Tighten wheel axle pinch bolts C
and D to the specified torque.

push down hard on the handlebar
several times to check for proper
fork operation. Tightening torque:
