Adjusting the shock absorber
assembly This shock absorber assembly is
equipped with a spring preload adjust-
ing nut.CAUTION:
ECA10100
Never attempt to turn an adjusting
mechanism beyond the maximum orminimum settings.
Adjust the spring preload as follows.
1. Loosen the locknut.
2. To increase the spring preload and
thereby harden the suspension,
turn the adjusting nut in direction
(a). To decrease the spring pre-load and thereby soften the sus-
pension, turn the adjusting nut in
direction (b).
NOTE:

To make the adjustment, use the
special wrench included in the ad-
ditional tool kit, which was handed
out separately at the purchase of
the vehicle.


The spring preload setting is deter-
mined by measuring distance A,
shown in the illustration. The short-
er distance A is, the higher the
spring preload; the longer distance
A is, the lower the spring preload.

3 With each complete turn of the ad-
justing nut, distance A is changed
by 2.0 mm (0.08 in).
3. Tighten the locknut to the specified
torque.
CAUTION:
ECA10120
Always tighten the locknut against
the adjusting nut, and then tightenthe locknut to the specified torque.
WARNING
EWA10220
This shock absorber contains highly
pressurized nitrogen gas. For prop-
er handling, read and understand
the following information before
handling the shock absorber. The
manufacturer cannot be held re-
sponsible for property damage or
personal injury that may result from
improper handling.

Do not tamper with or attempt to
open the gas cylinder.


Do not subject the shock ab-
sorber to an open flame or other
high heat sources, otherwise it
may explode due to excessive
gas pressure.


Do not deform or damage the
gas cylinder in any way, as this
will result in poor damping per-
formance.


Always have a Yamaha dealerservice the shock absorber.

Checking the brake and clutch
fluid levels Front brake
Rear brakeClutch
Insufficient brake or clutch fluid may al-
low air to enter the brake or clutch sys-
tems, possibly causing them to become
ineffective.
NOTE:The rear brake fluid reservoir is locatedunder the rider seat. (See page 3-14.)
Before riding, check that the brake and
clutch fluids are above the minimum
level marks and replenish if necessary.
A low brake or clutch fluid level may in-
dicate brake or clutch system leakage
and/or worn brake pads. If the brake or
clutch levels are low, be sure to check
the brake or clutch systems for leakage
and the brake pads for wear.Observe these precautions:


When checking the brake and
clutch fluid levels, make sure that
the top of each reservoir is level.


Use only the recommended quality
brake fluid, otherwise the rubber
seals may deteriorate, causing
leakage and poor braking or clutch
performance.


Refill with the same type of brake
fluid. Mixing fluids may result in a
harmful chemical reaction and
lead to poor braking or clutch per-
formance.


Be careful that water does not en-
ter the brake or clutch fluid reser-
voir when refilling. Water will
significantly lower the boiling point
of the fluid and may result in vapor
lock.


Brake fluid may deteriorate paint-
ed surfaces or plastic parts. Al-
ways clean up spilled fluid
immediately.
