TIP●A special wrench can be obtained at a Yamaha
dealer to make this adjustment.●The spring preload setting is determined by
measuring distance A, shown in the illustration.
The shorter distance A is, the higher the spring
preload; the longer distance A is, the lower the
spring preload. With each complete turn of the
adjusting nut, distance A is changed by 1.5 mm
(0.06 in).
3. Tighten the locknut to the specified torque.NOTICE: Always tighten the locknut
against the adjusting nut, and then tighten
it to the specified torque.

4Rebound damping force
Turn the rebound damping force adjusting screw in
direction (a) to increase the rebound damping
force and thereby harden the damping, and in di-
rection (b) to decrease the rebound damping force
and thereby soften the damping.
Compression damping force
Compression damping force (for fast compression
damping)To increase the compression damping force and
thereby harden the compression damping, turn the
compression damping force adjusting bolt in direc-
tion (a). To decrease the compression damping
force and thereby soften the compression damp-
ing, turn the adjusting bolt in direction (b).

WARNING
EWB00430This shock absorber assembly contains highly
pressurized nitrogen gas. Read and under-
stand the following information before han-
dling the shock absorber assembly.●Do not tamper with or attempt to open the
cylinder assembly.●Do not subject the shock absorber assembly
to an open flame or other high heat source.
This may cause the unit to explode due to ex-
cessive gas pressure.●Do not deform or damage the cylinder in any
way. Cylinder damage will result in poor
damping performance.
●Do not dispose of a damaged or worn out
shock absorber assembly yourself. Take the
shock absorber assembly to a Yamaha deal-
er for any service.
Compression damping setting (for slow com-
pression damping):Minimum (soft):16 click(s) in direction (b)*
Standard: 11 click(s) in direction (b)*
Maximum (hard): 1 click(s) in direction (b)*
* With the adjusting screw fully turned in di- rection (a)

EBU19541Fuel Make sure that there is sufficient fuel in the tank.
(See page 4-10.)EBU19560Engine oil Make sure that the engine oil is at the specified lev-
el. Add oil as necessary. (See page 8-13.)EBU19631Coolant Make sure that the coolant is at the specified level.
Add coolant as necessary. (See page 8-17.)TIPThe coolant level must be checked on a cold en-
gine since the level varies with engine tempera-
ture.EBU19712Front and rear brakes Brake lever and brake pedal●Check that there is no free play in the brake le-
ver. If there is free play, have a Yamaha dealer
check the brake system.
●Check for correct brake pedal height. (See page
8-34.) If the pedal height is incorrect, have a
Yamaha dealer adjust it.●Check the operation of the lever and pedal. They
should move smoothly and there should be a
firm feeling when the brakes are applied. If not,
have a Yamaha dealer check the brake system.
Brake fluid level
Check the brake fluid level. Add fluid if necessary.
(See page 8-31.)
Brake fluid leakage
Check to see if any brake fluid is leaking out of the
pipe joints or brake fluid reservoirs. Apply the
brakes firmly for one minute. If there is any leak-
age, have a Yamaha dealer check the brake sys-
tem.
Brake operation
Test the brakes at slow speed after starting out to
make sure they are working properly. If the brakes
do not provide proper braking performance, check
the brake pads for wear. (See page 8-30.) Specified brake fluid:

EBU19761Throttle lever Check the operation of the throttle lever. It must
open smoothly and spring back to the idle position
when released. Have a Yamaha dealer correct if
necessary.EBU19770Drive chain Check the condition of the drive chain and check
the drive chain slack. Lubricate and adjust the
drive chain as necessary. (See page 8-38.)EBU19814Tires Check tire pressure regularly to make sure it is at
the recommended specifications. Also check for
wear and damage.
Tire pressure
Use the low-pressure tire gauge to check and ad-
just tire pressures when the tires are cold. Tire
pressures must be equal on both sides.
WARNING! Operation of this vehicle with im- proper tire pressure may cause severe injury
or death from loss of control or rollover. Tire
pressure below the minimum specified could also cause the tire to dislodge from the rim un-
der severe riding conditions.
[EWB02541]
Set tire
pressures to the following specifications:
The low-pressure tire gauge is included as stan-
dard equipment. Make two measurements of the
tire pressure and use the second reading. Dust or
dirt in the gauge could cause the first reading to be
incorrect. Recommended tire pressure:
Fron t27.5 kPa (0.275 kgf/cm², 4.0 psi)
Rear 27.5 kPa (0.275 kgf/cm², 4.0 psi)
Minimum tire pressure: Fron t24.5 kPa (0.245 kgf/cm², 3.6 psi)
Rear 24.5 kPa (0.245 kgf/cm², 3.6 psi)
Maximum tire seating pressure: Fron t250 kPa (2.5 kgf/cm², 36 psi)
Rear 250 kPa (2.5 kgf/cm², 36 psi)
