Periodically check the throttle grip free
play and, if necessary, have a Yamaha

Valve clearanceThe valves are an important engine
component, and since valve clearance
changes with use, they must be
checked and adjusted at the intervals
specified in the periodic maintenance
chart. Unadjusted valves can result in
improper air-fuel mixture, engine
noise, and eventually engine damage.
To prevent this from occurring, have
your Yamaha dealer check and adjust
the valve clearance at regular intervals.TIPThis service must be performed when
the engine is cold.

TiresTires are the only contact between the
vehicle and the road. Safety in all con-
ditions of riding depends on a relatively
small area of road contact. Therefore, it
is essential to maintain the tires in good
condition at all times and replace them
at the appropriate time with the speci-
fied tires.
Tire air pressure
The tire air pressure should be
checked and, if necessary, adjusted
before each ride.
WARNING

proper tire pressure may cause se-
vere injury or death from loss of
control. The tire air pressure must be

Tire inspection
The tires must be checked before each

the specified limit, if the tire has a nail
or glass fragments in it, or if the side-
wall is cracked, have a Yamaha dealer
replace the tire immediately.TIPThe tire tread depth limits may differ
from country to country. Always com-

Cast wheelsTo maximize the performance, durabil-
ity, and safe operation of your vehicle,
note the following points regarding the
specified wheels.
The wheel rims should be
checked for cracks, bends, warp-
age or other damage before each
ride. If any damage is found, have
a Yamaha dealer replace the
wheel. Do not attempt even the
smallest repair to the wheel. A de-
formed or cracked wheel must be
replaced.
The wheel should be balanced
whenever either the tire or wheel
has been changed or replaced. An
unbalanced wheel can result in
poor performance, adverse han-
dling characteristics, and a short-
ened tire life.
After repairing or replacing the
front tire, tighten the valve stem
nut and locknut to the specified
torques.

cable length and adjust if necessary.
1. Release the rear brake lock lever.
2. To increase the rear brake lock ca- ble length, turn the adjusting nut at
the rear brake caliper in direction
(a). To decrease the rear brake
lock cable length, turn the adjust-
ing nut in direction (b). 3. Confirm that the rear brake lock
lever (page 5-18) functions prop-
erly and that the rear wheel rotates
freely when unlocked.

Checking the rear brake lockThe rear brake lock must be checked
at the intervals specified in the periodic
maintenance and lubrication chart.
1. Adjust the rear brake lock cable.
2. Apply the rear brake lock, and then try to push the vehicle to con-
firm that the rear brake lock func-
tions properly.
3. The rear brake lock caliper is pro- vided with a wear indicator, which
allows you to check the rear brake
lock pads. To check the rear brake
lock pads, check the position of
the indicator when the rear brake
lock lever is applied. If the indica-
tor has passed the wear indicator
groove, have a Yamaha dealer
check the rear brake lock.
4. Make sure that there are no tears or cracks on the rubber boot.

Checkin g the brake flui d levelBefore riding, check that the brake fluid
is above the minimum level mark.TIPMake sure the reservoir is parallel to
the ground when checking.NOTICE
ECA17641
Brake fluid may damag e painted
surfaces or plastic parts. Always
clean up spille d flui d imme diately.Front brake Rear
brake
As the brake pads wear, it is normal for
the brake fluid level to gradually go
down. A low brake fluid level may indi-
cate worn brake pads or brake
system leakage; therefore, be sure
to check the brake pads for wear
and the brake system for leakage.
If the brake fluid level goes down
suddenly, have a Yamaha dealer
check the cause before further rid-
ing.
WARNING
EWA15991
Improper maintenance can result in
loss of b raking a bility. O bserve
these precautions:
Insufficient brake flui d may al-
low air to enter the brake sys-
tem, re ducin g brakin g
performance.
Clean the filler cap before re-
movin g. Use only DOT 4 brake
flui d from a seale d container.
Use only the specified b rake flu-
i d ; otherwise, the ru bber seals
may deteriorate, causin g leak-
a g e.
Refill with the same type of
brake flui d. A ddin g a brake flui d
other than DOT 4 may result in a
harmful chemical reaction.
Be careful that water d oes not
enter the brake flui d reservoir
when refillin g. Water will si gnifi-
cantly lower the boilin g point of
