Rear shock absorber adjustment
The spring preload and damping force of the rear
shock absorber can be adjusted to suit the rider’s
weight and riding conditions.
WARNING
_ This shock absorber contains highly pressur-
ized nitrogen gas. Read and understand the
following information before handling the
shock absorber.
1. Do not tamper with or attempt to open the
cylinder assembly.
2. Do not subject the shock absorber to an
open flame or other high heat source.
This may cause the unit to explode due to
excessive gas pressure.
3. Do not deform or damage the cylinder in
any way. Cylinder damage will result in
poor damping performance.
4. Take the shock absorber to a Yamaha
dealer for any service. _Adjust spring preload as follows:
1. Loosen the locknut.
2. Turn the adjusting ring in direction
a to in-
crease the spring preload and in direction

the pipe joints or master cylinders. Apply the
brakes firmly for one minute. If there is any
leakage, have the machine inspected by a
Yamaha dealer.

Test the brakes at slow speed after starting out
to make sure they are working properly. If the
brakes do not provide proper braking perfor-
mance, inspect the brake pads for wear. (See
page 8-39.)WARNING
_ Always check the brakes at the start of every

WARNING
_

Do not overfill the fuel tank. Fuel expands
when it heats up. If the fuel tank is over-
filled, fuel could spill out due to heat from
the engine or the sun.


Be careful not to spill fuel, especially on
the engine or exhaust pipe which can
cause a fire and severe injury. Wipe up any
spilled fuel immediately.


Do not refuel right after the engine has
been running and is still very hot.


Be sure the fuel tank cap is closed secure-
ly.

To decelerate:
When slowing down or stopping, release the throt-
tle and apply the brakes smoothly and evenly. As
you slow down, shift to a lower gear. Be sure that
the engine has sufficiently slowed before engaging
a lower gear. Improper use of the brakes or shift-
ing can cause the tires to lose traction, reducing
control and increasing the possibility of an acci-
dent.
WARNING
Make sure the engine has sufficiently slowed
before shifting to a lower gear. Engaging a low-
er gear when the engine speed is too high
could make the wheels stop rotating. This
could cause loss of control, an accident and
injury. It could also cause engine or drive train
damage.
