FRONT FORK
HANDLING NOTE
Support the machine securely so there is no
danger of it falling over.
The front fork requires careful attention. So it is
recommended that the front fork be maintained
at the dealers.
To prevent an accidental explosion of air,
the following instructions should be ob-
served:
• The front fork with a built-in piston rod has
a very sophisticated internal construction
and is particularly sensitive to foreign ma-
terial. Use enough care not to allow any
foreign material to come in when the oil is
replaced or when the front fork is disas-
sembled and reassembled.
• Before removing the base valves or front
forks, be sure to extract the air from the air
chamber completely.
REMOVING THE DAMPER ASSEMBLY
1. Loosen:
• Damper assembly "1"
Before removing the front fork from the ma-
chine, loosen the damper assembly with the
cap bolt ring wrench "2".
REMOVING THE ADJUSTER
1. Drain the outer tube of its front fork oil at its
top.
2. Loosen:
• Adjuster "1"
3. Remove:
• Adjuster "1"
• While compressing the inner tube "2", set the
cap bolt ring wrench "4" between the inner
tube and locknut "3".
• Hold the locknut and remove the adjuster.
Do not remove the locknut as the damper
rod may go into the damper assembly and
not be taken out.
REMOVING THE INNER TUBE
1. Remove:
• Dust seal "1"
• Stopper ring "2"
Using slotted-head screwdriver.
Take care not to scratch the inner tube.
