How to Remove the Air Filter

Cleaning the Air Filter
- Fill a bucket two-thirds with lukewarm water and add dish soap.
- Fully submerge the filter, gently squeeze (do not wring or twist) to release dirt and old oil. Repeat several cycles for heavy buildup.
- Rinse thoroughly with clean water.
- Let the filter air dry completely in a dust-free environment.
Oiling and Reinstalling the Filter
- Once dry, evenly apply foam filter oil throughout the filter's surface. Massage oil in for full coverage but avoid oversaturation.
- Lightly grease the filter rim to ensure a tight seal against the airbox and prevent dirt intrusion.
- Reinstall the filter, secure the wing nut, and double-check for proper fit with no gaps.
- Replace the seat and tighten down securely.
When to Replace the Air Filter
- Heavy tears, holes, or damaged foam signal replacement is necessary.
- If the filter remains stained, greasy, or does not regain its shape after cleaning.

Proprietary MotoSport Tips for YZ250F Owners
- Monitor after Dusty Rides: The 2013 YZ250F's airbox is well designed, but riding in sand or heavy dust means more frequent inspection – check your filter before each ride during harsh conditions.
- Factory Lubricants: For best results, use Yamalube filter oil and cleaner, which are formulated to work with Yamaha foam filters for maximum engine protection and airflow.
- Quick Routine: Thanks to Yamaha's "one-wrench" maintenance design, air filter service should take no more than 30 minutes with practice.
- Seal the Rim: Always apply a light coat of grease along the rim for a dustproof seal. This step is crucial for the YZ250F's high-performance engine.
Common Mistakes to Avoid
- Do not wring or twist the foam – this damages the filter.
- Never oil the filter while still wet. It must be completely dry for proper oil adhesion.
- Do not overtighten the wing nut, which could deform the filter and reduce its efficiency.
The 2013 Yamaha YZ250F air filter system is simple to maintain, ensuring maximum airflow and engine protection. Regular cleaning and timely replacement help you get the best performance – so keep MotoSport parts and supplies on hand for every ride.
