assemb lyThis shock absorber assembly is
equipped with a spring preload adjust-
ing nut, a rebound damping force ad-
justing screw and a compression
damping force adjusting screw.NOTICE
ECA10102
To avoid d amag ing the mechanism,
d o not attempt to turn b eyond the
maximum or minimum settin gs.Sprin g preloa d
Adjust the spring preload as follows. 1. Loosen the clamp bolts, and then remove the air filter joint.
2. Loosen the locknut.
3. Turn the adjusting nut in direction(a) to increase the spring preload.
Turn the adjusting nut in direction
(b) to decrease the spring preload. 
A special wrench can be ob-
tained at a Yamaha dealer to
make this adjustment.
 The spring preload setting is
determined by measuring
distance A, shown in the illus-
tration. The longer distance A
is, the lower the spring pre-
load; the shorter distance A
is, the higher the spring pre-
load. With each complete
turn of the adjusting nut, dis-
tance A is changed by 1.5
mm (0.06 in).

A djustin g the car buretorThe carburetor is an important part of
the engine and requires very sophisti-
cated adjustment. Therefore, most
carburetor adjustments should be left
to a Yamaha dealer, who has the nec-
essary professional knowledge and ex-
perience. The adjustment described in
the following section, however, may be
serviced by the owner as part of rou-
tine maintenance.NOTICE
ECA10551
The car buretor has been set an d ex-
tensively teste d at the Yamaha fac-
tory. Chang ing these settin gs
without sufficient technical knowl-
e dge may result in poor perfor-
mance of or d amage to the en gine.

TiresTires are the only contact between the
vehicle and the road. Safety in all con-
ditions of riding depends on a relatively
small area of road contact. Therefore, it
is essential to maintain the tires in good
condition at all times and replace them
at the appropriate time with the speci-
fied tires.
Tire air pressure
The tire air pressure should be
checked and, if necessary, adjusted
before each ride.
WARNING
EWA14382
Operation of this vehicle with im-
proper tire pressure may cause se-
vere injury or d eath from loss of
control.  The tire air pressure must b e
checked and a djuste d on col d
tires (i.e., when the temperature
of the tires equals the am bient
temperature). 
The tire air pressure must be
a d juste d in accor dance with the
wei ght of the ri der, the ri din g
speed , and the ri din g con di-
tions.
Tire inspection
The tires must be checked before each
ride.
