WARNING
EWA10181
Always a djust both fork le gs equally,
otherwise poor han dlin g an d loss of
sta bility may result.Each side of the front fork is equipped
with a rebound damping force adjust-
ing screw and compression damping
force adjusting screw.
 When adjusting the damping force
settings, turn the adjuster in direc-
tion (a) until it stops, and then
count the clicks in direction (b).
 When turning a damping force ad-
juster in direction (a), the stop po-
sition and the 1 click position may
be the same.
 Although a damping force adjust-
er may click beyond the stated
minimum settings, such adjust-
ments are ineffective and may
damage the suspension.

Si destan dThe sidestand is located on the left
side of the frame. Raise the sidestand
or lower it with your foot while holding
the vehicle upright.TIPThe built-in sidestand switch is part of
the ignition circuit cut-off system,
which cuts the ignition in certain situa-
tions. (See the following section for an
explanation of the ignition circuit cut-
off system.)
WARNING
EWA10242
The vehicle must not be ri dden with
the si destan d d own, or if the si de-
stan d cannot b e properly move d up
(or does not stay up), otherwise the
si destan d coul d contact the groun d
an d d istract the operator, resultin g
in a possi ble loss of control.
Yamaha’s ig nition circuit cut-off
system has been desi gne d to assist
the operator in fulfillin g the respon-
si bility of raisin g the si destan d b e-
fore startin g off. Therefore, check this system re
gularly an d have a
Yamaha dealer repair it if it does not
function properly.
EAU57952
I g nition circuit cut-off systemThis system prevents in-gear engine
starts unless the clutch lever is pulled
and the sidestand is up. Also, it will
stop the running engine should the
sidestand be lowered while the trans-
mission is in gear.
Periodically check this system via the
following procedure.TIP This check is most reliable if per-
formed with a warmed-up engine.
 See pages 3-2 and 3-3 for switch
operation information.
