WARNING

Always a djust both shock ab sorber
assem blies equally, otherwise poor
han dlin g an d loss of stab ility 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

Troubleshootin 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.
WARNING
EWA15142
When checkin g the fuel system, do
not smoke, an d make sure there are
no open flames or sparks in the ar-
ea, inclu din g pilot lig hts from water heaters or furnaces. Gasoline or

asoline vapors can i gnite or ex-
