Appearance Care
Condensation Control
Some condensation can form within the
transmission cavity as well. This is natural and just
one more reason you should change the engine and
transmission oil often.
After Cleaning Lubrication
There are some things you should do just after
washing your CRF to help prevent rust and
corrosion.
Once your CRF is clean and dry, you should
protect any bare steel from rusting by applying a
light coating of a rust-inhibitor. Lubricate the drive
chain and drive sprocket after removing and
thoroughly cleaning in solvent. Be sure the chain is
wiped clean and is dry before applying the chain
lube.
Follow the suggestions given in the pages of this
manual for lubricating items such as the brake and
clutch lever pivot points and footpeg pivot pins.

Servicing Your Honda
Aluminum Frame Maintenance
Aluminum corrodes when it comes in contact with
dust, mud and road salt.
To remove stains, use Scotch Brite Hand Pad
#7447 (maroon) or an equivalent.
Wet the pad and polish the surface using strokes
parallel to the length of the frame.
Clean the frame using a wet sponge and a mild
detergent, then rinse well with clean water. Dry the
frame with a soft clean cloth, using strokes parallel
to the length of the frame.
NOTICE
Do not use steel wool to clean the frame as it could
damage or discolor the frame surface.
Muffler stain remover (Scotch Brite Hand Pad
#7447-maroon) is for removing stains on the non-
coated aluminum frame only.
Exhaust Pipe and Muffler Maintenance
The exhaust pipe and muffler are stainless steel but
may became stained by mud or dust.
To remove mud or dust, use a wet sponge and a
liquid kitchen abrasive, then rinse well with clean
water. Dry with chamois or a soft towel.
If necessary, remove heat stains by using a
commercially available fine texture compound.
Then rinse by the same manner as removing mud
or dust.
