Frequency of Cleaning & Replacement

Required Supplies
- Nitrile gloves
- Clean rags or paper towels
- Contact cleaner or approved air filter solvent

Step-by-Step Air Filter Removal
- Remove the seat for filter access.
- Loosen and remove the wingnut holding the air filter in place.
- Turn the filter 45–90 degrees and carefully withdraw it with the filter cage.
- Gently separate the foam element from the cage. – avoid tears or frame damage to ensure a proper seal.
Cleaning the Airbox
- Place a clean rag inside the airbox to block dirt entry during cleaning.
- Use contact cleaner or solvent with a rag to meticulously remove dust and debris inside the airbox. – inspect for leftover grit and clean thoroughly.
Cleaning the Filter
- Use only approved filter cleaner or solvent for the foam filter (never gasoline, which degrades the foam and harms engine life).
- Submerge the foam element and gently squeeze out dirt, never wringing or pulling hard. – preserve filter integrity.
- Rinse using clean water and repeat if necessary until the filter is visibly clean.
- Allow the filter to dry fully, preferably air drying out of direct sunlight.
Oiling the Filter
- Saturate the dry foam filter evenly with high-quality foam air filter oil. – squeeze out excess oil gently, then wrap in a clean towel and press gently to blot excess.
- Ensure oil coverage is uniform for maximum dust-trapping capacity.
Reinstalling the Filter
- Align the foam filter with the cage and reinstall to the airbox. – make sure edges seal without gaps for proper dust protection.
- Reinstall the wingnut securely, being careful not to overtighten.
- Replace the seat and perform a final check for any errant debris.
