For Germany only: Whenever
replacement is necessary, use a
fuel tank cap of the same spe-
cial design as the original.

NOTE:_ If knocking (or pinging) occurs, use
gasoline of a different brand or with a
higher octane grade. _

Fuel tank breather hose Before operating the motorcycle:l
Check the fuel tank breather hose
connection.
l
Check the fuel tank breather hose
for cracks or damage, and replace
it if damaged.
l

Storage compartment This storage compartment is designed
to hold a genuine Yamaha U-LOCK.
(Other locks may not fit.) When placing
a U-LOCK in the storage compartment,
securely fasten it with the straps. When
the U-LOCK is not in the storage com-
partment, be sure to secure the straps
to prevent losing them.
When storing the owner’s manual or
other documents in the storage com-
partment, be sure to wrap them in a
plastic bag so that they will not get wet.
When washing the motorcycle, be
careful not to let any water enter the
storage compartment.

Adjusting the front fork This front fork is equipped with spring
preload adjusting bolts, rebound damp-
ing force adjusting screws and com-
pression damping force adjusting
screws.
EW000035
WARNING
_ Always adjust both fork legs equal-
ly, otherwise poor handling and loss
of stability may result. _
Spring preload
To increase the spring preload and
thereby harden the suspension, turn
the adjusting bolt on each fork leg in di-
rection
a. To decrease the spring pre-
load and thereby soften the
suspension, turn the adjusting bolt on
each fork leg in direction

justing mechanism with the top of the
front fork cap bolt. _

CAUTION:_ Never attempt to turn an adjusting
mechanism beyond the maximum
or minimum settings. _NOTE:_ Although the total number of clicks of a
damping force adjusting mechanism
may not exactly match the above spec-
ifications due to small differences in
production, the actual number of clicks
always represents the entire adjusting
range. To obtain a precise adjustment,
it would be advisable to check the num-
ber of clicks of each damping force ad-
justing mechanism and to modify the
specifications as necessary. _

WARNING
_ This shock absorber contains high-
ly pressurized nitrogen gas. For
proper handling, read and under-
stand the following information be-
fore handling the shock absorber.
The manufacturer cannot be held re-
sponsible for property damage or
personal injury that may result from
improper handling.l
Do not tamper with or attempt to
open the gas cylinder.
l
Do not subject the shock ab-
sorber to an open flame or other
high heat sources, otherwise it
may explode due to excessive
gas pressure.
l
Do not deform or damage the
gas cylinder in any way, as this
will result in poor damping per-
formance.
l
Always have a Yamaha dealer
service the shock absorber.

Luggage strap holders There are four luggage strap holders
below the passenger seat, two of which
can be turned out for easier access.
EAU01571
EXUP system This motorcycle is equipped with
Yamaha’s EXUP (EXhaust Ultimate
Power valve) system. This system
boosts engine power by means of a
valve that regulates the diameter of the
exhaust pipe. The EXUP system valve
is constantly adjusted in accordance
with the engine speed by a computer-
controlled servomotor.
EC000027
CAUTION:_ l
The EXUP system has been set
and extensively tested at the
Yamaha factory. Changing
these settings without sufficient
technical knowledge may result
in poor performance of or dam-
age to the engine.
l
If the EXUP system does not op-
erate, have a Yamaha dealer
check it.
