Front Suspension Adjustments
17. Clean the spring and spring seat thoroughly
with a high flash point solvent to remove all
metal particles and dirt.
18. Dry the spring and spring seat with air pressure
rather than a shop towel. Using a shop towel
allows lint to stick to the springs. Lint or any
particles that stick in the damping passages can
cause inconsistent damping.
19. Turn the adjuster needle rod (14)
counterclockwise and remove it from the fork
cap (2).
Check the adjuster needle rod for bent or
damage.
Check that the O-rings (20) on the fork cap and
needle rod are in good condition. Apply the
recommended fork oil to the O-rings.

23. Reaching through the two adjacent coils near
the oil lock valve, hold the spring guide (22)
