Appearance Care
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.
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.
