WARNING
EWA10181
Always a djust both fork le gs equally,
otherwise poor han dlin g an d loss of
sta bility may result.
This front fork is equipped with spring
preload adjusting bolts, rebound
damping force adjusting screws and
compression damping force adjusting
screws.
NOTICE
ECA10102
To avoi d d amag ing the mechanism,
d o not attempt to turn b eyond the
maximum or minimum settin gs.
Sprin g preloa d
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 (b).
The spring preload setting is deter-
mined by measuring distance A,
shown in the illustration. The shorter distance A is, the higher the spring pre-
load; the longer distance A is, the lower
the spring preload.
Re
boun d d ampin g force
To increase the rebound damping
force and thereby harden the rebound
damping, turn the adjusting screw on
each fork leg in direction (a). To de-
crease the rebound damping force and
thereby soften the rebound damping,
turn the adjusting screw on each fork
leg in direction (b).

Supportin g the motorcycle
Since this model is not equipped with a
centerstand, follow these precautions
when removing the front and rear
wheel or performing other mainte-
nance requiring the motorcycle to
stand upright. Check that the motorcy-
cle is in a stable and level position be-
fore starting any maintenance. A
strong wooden box can be placed un-
der the engine for added stability.
To service the front wheel
1. Stabilize the rear of the motorcy- cle by using a motorcycle stand
or, if an additional motorcycle
stand is not available, by placing a
jack under the frame in front of the
rear wheel.
2. Raise the front wheel off the ground by using a motorcycle
stand.
To service the rear wheel
Raise the rear wheel off the ground by
using a motorcycle stand or, if a motor-
cycle stand is not available, by placing
a jack either under each side of the
frame in front of the rear wheel or under
each side of the swingarm.

Trou bleshootin g
Although 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 charts
represent quick and easy procedures
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, d o
not smoke, an d make sure there are
no open flames or sparks in the ar-
ea, inclu din g pilot li ghts from water
heaters or furnaces. Gasoline or
g asoline vapors can i gnite or ex-
plo de, causin g severe injury or prop-
erty damag e.
