Finishing Touches
Refer to Safety Precautions on page 109.
After washing your ATV, consider using a commercially available
spray cleaner/polish or quality liquid or paste wax to finish the job.
Use only a non-abrasive polish or wax made specifically for
motorcycles or automobiles. Apply the polish or wax according to
the instructions on the container.
If a surface on your ATV is chipped or scratched, your dealer has
touch-up paint to match your ATV's color. Be sure to use your ATV's
color code (page 231) when you buy touch-up paint.
If the frame has a chip that exposes the metal, first apply primer (to
prevent corrosion) and then apply the touch-up paint. Several thin
layers of touch-up paint are better than one thick coat.
Exhaust Pipe and Muffler Maintenance
The exhaust pipe and muffler are stainless steel but may become
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.
