Tightness/binding/rough spots →
Repeat the steps 2 to 12.
14. Compress the front fork fully.
15. Fill:
• Front fork oil
Until outer tube top surface with
recommended fork oil "1".
• Be sure to use recommended
fork oil. If other oils are used,
they may have an excessively ad-
verse effect on the front fork per-
formance.
• Never allow foreign materials to
enter the front fork.
16. After filling, pump the damper rod
"1" slowly up and down more than
10 times to distribute the fork oil.
17. Fill:
• Front fork oil
Until outer tube top surface with
recom-mended fork oil once
more.
18. After filling, pump the outer tube
"1" slowly up and down (about
200 mm (7.9 in) stroke) to distrib-
ute the fork oil once more.
Be careful not to excessive full stroke.
A stroke of 200 mm (7.9 in) or more
will cause air to enter. In this case, re-
peat the steps 15 to 18.
19. Wait ten minutes until the air bub-
bles have been removed from the
front fork, and the oil has dis-
pense evenly in system before
setting recommended oil level.
Fill with the fork oil up to the top end
of the outer tube, or the fork oil will not
spread over to every part of the front
forks, thus making it impossible to ob-
tain the correct level.
Be sure to fill with the fork oil up to the
top of the outer tube and bleed the
front forks.
