Service and Maintenance
(1) COMPRESSION ADJUSTER
Rear Suspension
The swingarm is controlled by a hydraulic shock
absorber with an aluminum reservoir for oil and
nitrogen gas pressure. The gas pressure in the reser-
voir is contained within a rubber bladder.
The rear shock absorber should always be adjusted
for the rider’s weight and race track conditions by
using one or more of the following methods.
• Rebound damping
Turning the rebound damping screw adjusts how
quickly the shock absorber extends.
• Compression damping
Turning the compression damping screw adjusts
how quickly the shock absorber compresses.
• Spring pre-load
Turning the spring pre-load adjuster adjusts the
spring initial pre-load length.
• Shock absorber spring
Optional stiffer and softer springs than the stan-
dard spring are available.
(1) REBOUND ADJUSTER
• When your NSF is new, your suspension will
break-in as you ride.
• After break-in is completed, test ride your NSF
with the rear suspension at the standard setting
before attempting any adjustments.
• Refer to page 7–7 for Suspension Adjustment
information. Make all compression and rebound
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 set-
tings, return to the standard position and start
over.
(1) COMPRESSION ADJUSTER
• For optimum fork performance, we recommended
that you disassemble and clean the fork after rid-
ing your NSF for three hours. See page 5–4 for
fork disassembly/assembly.
• Replace the fork fluid every three races. See page
5–10 for oil level adjustment after changing the
fork fluid.
• Use Honda Ultra Cushion Oil Special or equivalent
with additives to assure maximum performance of
your NSF’s front suspension.
• Periodically check and clean all front suspension
parts to assure top performance. Check the oil
seals for dust, dirt and foreign materials. Check
the fluid for any contamination.
• Refer to page 7–7 for Suspension Adjustment
information. Make all compression and rebound
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 set-
tings, return to the standard position and start
over.
