WARNING
EWA10211
Always a djust both shock a bsor ber
assem blies equally, otherwise poor
han dlin g an d loss of sta bility may re-
sult.Each shock absorber assembly is
equipped with a spring preload adjust-
ing ring and rebound and compression
damping force adjusting knobs.
Sprin g preloa d
Adjust the spring preload as follows. 1. Loosen the lock screw 1/2 turn counterclockwise. 2. To increase the spring preload
and thereby harden the suspen-
sion, turn the adjusting ring in di-
rection (a). To decrease the spring
preload and thereby soften the
suspension, turn the adjusting ring
in direction (b). Use the special wrench in-
cluded in the owner’s tool kit
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 higher the spring pre-
load; the shorter distance A
is, the lower the spring pre-
load. With each complete
turn of the adjusting ring, dis-
tance A changes by 1.5 mm
(0.06 in).
Be sure to turn the adjusting
ring so that the lock screw is
facing outward.1. Lock screw

To install the rear wheel 1. Place the wheel and the brake cal- iper bracket in the original posi-
tion.
2. Insert the wheel axle through the brake caliper bracket and wheel
from the right-hand side, and then
install the axle nut.
3. Install the drive chain onto the rear sprocket.
4. Connect the brake torque rod to the brake caliper bracket by in-
stalling the bolt and the nut.
5. Install the brake caliper by install- ing the bolts.
TIPMake sure that there is enough space
between the brake pads before install-
ing the brake caliper onto the brake
disc.6. Lower the rear wheel so that it ison the ground, and then put the
sidestand down.
7. Adjust the drive chain slack. (See page 6-22.) 8. Tighten the axle nut, brake caliper

Trou bleshootin gAlthough Yamaha motorcycles receive
a thorough inspection before shipment
from the factory, trouble may occur
during operation. Any problem in the
fuel, compression, or ignition systems,
for example, can cause poor starting
and loss of power.
The following troubleshooting chart
represents a quick and easy procedure
for checking these vital systems your-
self. However, should your motorcycle
require any repair, take it to a Yamaha
dealer, whose skilled technicians have
the necessary tools, experience, and
know-how to service the motorcycle
properly.
Use only genuine Yamaha replace-
ment parts. Imitation parts may look
like Yamaha parts, but they are often
inferior, have a shorter service life and
can lead to expensive repair bills.
