Starter (choke) lever “” Starting a cold engine requires a richer
air-fuel mixture, which is supplied by
the starter (choke).
Move the lever in direction
a to turn on
the starter (choke).
Move the lever in direction
b to turn off
the starter (choke).
ECA00038
CAUTION:_ Do not use the starter (choke) for
more than 3 minutes as the exhaust
pipe may discolor from excessive
heat. In addition, extended use of
the starter (choke) will cause after-
burning. If this occurs, turn off the
starter (choke). _

To install the seat
1. Insert the projections on the front
of the seat into the seat holder as
shown.
2. Push the rear of the seat down to
lock it in place.
3. Remove the key.
NOTE:_ Make sure that the seat is properly se-
cured before riding. _

Helmet holder To open the helmet holder, insert the
key into the lock, and then turn the key
as shown.
To lock the helmet holder, turn the key
to the original position, and then re-
move it.

WARNING
_ Never ride with a helmet attached to
the helmet holder, since the helmet
may hit objects, causing loss of
control and possibly an accident. _

Storage compartment This storage compartment is designed
to hold an optional genuine Yamaha U-
LOCK. (Other locks may not fit.) When
placing a U-LOCK in the storage com-
partment, securely fasten it with the
straps. When the U-LOCK is not in the
storage compartment, be sure to se-
cure 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.

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

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. _

mechanism may not exactly match the
above specifications due to small dif-
ferences in production, the actual num-
ber of clicks always represents the

to check the number of clicks of the re-

Compression damping force
To harden the compression damping,
decrease the setting by turning the ad-
justing screw. To soften the compres-
sion damping, increase the setting by
turning the adjusting screw. Make sure
that the position indicator is aligned
with the appropriate setting.CI-10EEAU00315
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.

Do not tamper with or attempt to
open the gas cylinder.


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.


Do not deform or damage the
gas cylinder in any way, as this
will result in poor damping per-
formance.


Always have a Yamaha dealer
service the shock absorber.
