Before & After Competition Maintenance
Before & After Competition Maintenance
Between Heats & Practice Maintenance
After practice or between heats 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 tyre air pressure.
• Check spoke tension, and make sure the rim
locks are secure.
• 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.

• 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 kPa (0 kgf/
cm 2 , 0 psi)) 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.)

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
discs.
Take care to prevent catching your fingers between
the chain and sprocket.
Remove the drive chain, clean and lubricate it
(pages 103, 104). Be sure the chain is wiped clean
and is dry before lubricating the chain.
