Before & After Competition Maintenance
Between Motos & Practice Maintenance
After practice or between motos you have
a chance to make additional checks and
adjustments.
• Clean accumulated dirt from under the fenders
and off the wheels, suspension components,
handgrips, controls, and footpegs. A stiff,
nylon parts cleaning brush works well.
• Check tire air pressure.
• Check spoke tension and rim lock security.
• Check to make sure the sprocket bolts and
nuts are secure.
• Clean the sides of the drive chain with a stiff,
nylon parts-cleaning brush. Lubricate and
adjust the chain as necessary.
Do not perform maintenance while engine is
running. Injury to your fingers or hands may
result.
• After adjustment, check that the chain adjuster
index marks (1) are in the same position on
each side. This will ensure that the rear wheel
is in proper alignment and allow maximum
performance from the rear disc brake.
Maintaining proper wheel alignment will also
extend brake pad wear.
After Competition Maintenance
It is important to the long term performance of
your CRF to practice a consistent maintenance
program. Right after the event is a good time to
begin your next maintenance cycle.
After Race Lubrication
Apply a light coating of rust-inhibiting oil to
the drive sprocket and any steel portions of the
chassis or engine where the paint has worn away.
This will prevent rusting of the exposed metal.
Apply rust-inhibiting oil more heavily if the
event was particularly wet or muddy. Take care to
avoid spraying any oil near the brake pads or the
brake disc.
Clean and lubricate the drive chain (page 98). Be
sure the chain is wiped clean and is dry before
lubricating the chain.
Take care to prevent catching your fingers
between the chain and sprocket.

• Suspend the front wheel above the ground
and use the fork air pressure release screws
(2) to release the built-up pressure (in excess
of normal atmospheric pressure: 0 psi (0 kPa,
0 kgf/cm
2
)) in the fork tubes. This pressure
is caused by normal fork action while riding.
(If you are riding at altitude, remember that
fork pressure of 0 at sea level will increase as
elevation increases.)
