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 Maintenance
The exhaust pipe is stainless steel, but may
became stained by oil or mud.
To remove mud or dust, use a wet sponge and a
liquid kitchen abrasive, then rinse well with clean
water. Dry with a 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.
