Service and Maintenance
Front Suspension
Inspection
1. Make sure that the fork surfaces and oil seals are
clean.
2. Check for signs of oil leakage. Damaged or leaking
fork seals should be replaced before you ride the
machine.
3. Make a quick check of fork operation by locking
the front brake and pushing down on the handle-
bars several times.
• When your NSF is new, break in your NSF to
ensure that the suspension has worked in.
• After break-in, test ride your NSF with the front
suspension at the standard setting before attempt-
ing any adjustments.
(1) WHEEL (2) TIRE
Wheels And Tires
The optional wheels and tires are available.
The wheels and tires should be selected for track con-
dition and temperature.
Proper air pressure will provided maximum stability
and tire life.
Check tire pressure frequently and adjust if neces-
sary.
Tire air pressure should be checked when the tires
are COLD.
Standard cold tire air pressure:
Front: 190 kPa (1.9 kg/cm 2 , 27 psi)
Rear: 180 kPa (1.8 kg/cm 2 , 26 psi)
Recommended cold tire air pressure:
Front: 170 – 190 kPa (1.7 – 1.9 kg/cm 2 , 24 – 27 psi)
Rear: 180 – 200 kPa (1.8 – 2.0 kg/cm 2 , 26 – 28 psi)
Inspect the wheel for damage.
Check the wheel runout. If runout is noticeable,
replace the wheel with a new one.
Check the axle for runout.
Check the condition of the front and rear wheel bear-
ings.

(1) REBOUND ADJUSTER
(2) PRELOAD ADJUSTER
Fork
The machine is shipped with a light coating of grease
on the forks. This is not an indication of a leak.
The fork should always be adjusted for the rider’s
weight and race track conditions by using one or
more of the following methods.
Basically, there are five adjustments you can make to
the front suspension:
• Rebound damping
Turning the rebound damping screw adjusts how
quickly the fork extends.
• Compression damping
Turning the compression damping screw adjusts
how quickly the fork compresses.
• Spring preload
Turning the spring preload adjuster adjusts the
spring initial preload length.
• Fork fluid volume
The effects of higher or lower fork fluid level are
only felt during final fork travel.
• Fork spring
Optional stiffer and softer springs than the stan-
dard spring are available.
