This model is equipped with a self-diag-
nosis device for various electrical cir-
cuits. If any of those circuits are defec-
tive, the engine trouble warning light
will start flashing. If this occurs, have a
Yamaha dealer check the vehicle.
This model is also equipped with a
self-diagnosis device for the immobi-
lizer system.
Turn the key to "ON". If any of the im-
mobilizer system circuits are defec-
tive, the immobilizer system indicator
light will flash, and it will indicate an er-
ror code.
If this occurs, have a Yamaha dealer
check the vehicle. However, if the indi-
cator light slowly flashes five times,
and then quickly flashes two times re-
peatedly, this error could be caused by
signal interference. If this occurs, try
the following.
1. Use the code re-registering key to
start the engine.
NOTE:
Make sure there are no other immobi-
lizer keys close to the main switch,
and do not keep more than one immo-
bilizer key on the same key ring! Im-
mobilizer system keys may cause sig-
nal interference, which may prevent
the engine from starting.
2. If the engine starts, turn it off and
try starting the engine with the
standard keys.
3. If one or both of the standard keys
do not start the engine, take the
vehicle, the code re-registering
key and both standard keys to a
Yamaha dealer and have the
standard keys re-registered.

Before operating the motorcycle:
●Check the fuel tank breather/
overflow hose connection.
●Check the fuel tank breather/
overflow hose for cracks or dam-
age, and replace it if damaged.
●Make sure that the end of the fuel
tank breather/overflow hose is not
blocked, and clean it if necessary.
●Make sure that the end of the fuel
tank breather/overflow hose is
positioned inside of the clamp.
ECA11400CAUTION:
Use only unleaded gasoline. The
use of leaded gasoline will cause
severe damage to internal engine
parts, such as the valves and piston
rings, as well as to the exhaust sys-
tem.
Your Yamaha engine has been de-
signed to use premium unleaded
gasoline with a research octane num-
ber of 95 or higher. If knocking (or
pinging) occurs, use a gasoline of a
different brand. Use of unleaded fuel
will extend spark plug life and reduce
maintenance costs.

Adjust the spring preload as follows.
1. Loosen the locknut.
2. To increase the spring preload
and thereby harden the suspen-
sion, turn the adjusting nut in di-
rection (a). To decrease the
spring preload and thereby soften
the suspension, turn the adjusting
nut in direction (b).
NOTE:
●Use the special wrench included
in the owner's tool kit to make the
adjustment.
●The spring preload setting is de-
termined by measuring distance
A, shown in the illustration. The
longer distance A is, the lower the
spring preload; the shorter dis-
tance A is, the higher the spring
preload. With each complete turn
of the adjusting nut, distance A
changes by 1.5 mm (0.059 in).
●When measuring distance A, the
rear wheel must be raised off the
ground. (See page 6-36).
