4. Fill:
• brake fluid reservoir
(with the specified amount of the rec-
ommended brake fluid)
WARNINGWARNING

• Use only the designated brake fluid.
Other brake fluids may cause the rub-
ber seals to deteriorate, causing leak-
age and poor brake performance.
• Refill with the same type of brake fluid
that is already in the system. Mixing
brake fluids may result in a harmful
chemical reaction, leading to poor
brake performance.
• When refilling, be careful that water
does not enter the brake fluid reser-
voir. Water will significantly lower the
boiling point of the brake fluid and
could cause vapor lock.
ACHTUNG:CAUTION:

Brake fluid may damage painted sur-
faces and plastic parts. Therefore,
always clean up any spilt brake fluid
immediately.

ASSEMBLING THE FRONT FORK LEGS
The following procedure applies to both of
the front fork legs.
WARNINGWARNING

• Make sure that the oil levels in both
front fork legs are equal.
• Uneven oil levels can result in poor
handling and a loss of stability.
NOTE:

• When assembling the front fork leg, be
sure to replace the following parts:
- inner tube bushing
- outer tube bushing
- oil seal
- dust seal
• Before assembling the front fork leg,
make sure that all of the components
are clean.
1. Install:
• damper rod assembly

13.Slowly stroke the outer tube
1
up and
down to distribute the fork oil once
more (1 stroke = about 100 mm, 3.94 in).
NOTE:

Be careful not to stroke the inner tube
over 100 mm as this will cause air to
enter. If the inner tube is stroked more
than 100 mm, repeat steps (12) and (13).
14.Before measuring the fork oil level, wait
ten minutes until the oil has settled and
the air bubbles have dispersed.
NOTE:

Be sure to bleed the front fork leg of any
residual air.
15.Measure:
• front fork leg oil level
