Servicing Your Honda 87
Suspension
Refer to Important Safety Precautions on page 23.
Loose, worn, or damaged suspension components
may adversely affect the handling and stability of
your CRF. If any suspension components appear
worn or damaged, see your dealer for further
inspection. Your dealer is qualified to determine
whether or not replacement parts or repairs are
needed.
Do not dispose of the fork; see your dealer.
•
When your CRF is new, break it in for
approximately 1 hour with the standard setting
to ensure that the suspension has broken-in
(page 19).
• After break-in, test run your CRF with the
front suspension at the standard setting before
attempting any adjustments.
• Adjust the left fork air pressure each riding.
See page 136 for left fork air pressure
adjustment.
• Replace the right fork outer tube fork oil every
3 races or 7.5 hours of running. See page 91 for
right fork oil replacement.
• Replace the left fork outer tube fork oil every 3
races or 7.5 hours of running. See page 100 for
outer tube fork oil.
• Replace the left fork inner chamber fork oil
every 3 races or 7.5 hours of running. See
page 102 for inner chamber fork oil
replacement.
• Replace the right fork damper oil every 9 races
or 22.5 hours of running. See page 95 for
damper fork oil replacement.
• Use HP Fork Oil, SS-19 or an equivalent
which contains special additives to assure
maximum performance of your CRF’s front
suspension.
• Periodically check and clean all front
suspension parts to assure top performance.
Check the dust seals for dust, dirt, and foreign
materials. Check the oil for any contamination.
•Refer to Suspension Adjustment Guidelines
(page 145) Make all rebound and compression
damping adjustments in one-click increments.
(Adjusting two or more clicks at a time may
cause you to pass over the best adjustment.)
Test ride after each adjustment.
• If you become confused about adjustment
settings, return to the standard position and
start over.
• If the fork is still too stiff/soft after adjusting
compression damping, determine which
portion of the travel is still too stiff/soft. This is
an important step that will help you solve
suspension problems.
1. Make sure that the fork protectors (1) and dust
seals (2) are clean and not packed with mud
and dirt.
2. Check for signs of oil leakage. Damaged or
leaking fork seals should be replaced before
your CRF is ridden.
3. Inspect the wear rings (3) for wear or damage.
Replace the wear ring if it is 0.06 in (1.5 mm)
or flush with the outer tube (4). Remove the
fork leg when replacing the wear ring.
Install the wear ring with its end gap (5) facing
rearward.
