Shop parts for a 2006 Honda CR250 Dirt Bike.
The air filter is critical for the performance and longevity of your 2006 Honda CR250. Regular cleaning and scheduled replacement ensure optimal airflow, protect the engine from harmful debris, and maintain throttle response. The CR250 features a foam air filter housed within the air cleaner case under the seat, designed for easy maintenance and replacement.
Why Air Filter Maintenance Matters on the 2006 Honda CR250
- High-Revving Engine – The CR250 is renowned for its aggressive powerband, demanding clean airflow for consistent performance.
- Off-Road Exposure – Riding motocross or trails exposes the filter to heavy dust, sand, and dirt, increasing the risk of clogging and engine wear.
- Model-Specific Note: The 2006 CR250 is the final year of Honda's iconic aluminum-framed two-stroke. Its unique chassis and airbox design make accessing and servicing the filter straightforward.
Step-by-Step Guide: Cleaning – Replacing the Air Filter
- Remove the Seat – Shrouds
- Use the seat bolts to release and lift off the seat. Remove the left shroud to access the air cleaner case cover.
- Open the Air Cleaner Case
- Unclip the air cleaner case cover, exposing the filter. Inspect for visible dirt or debris around the air boot – wipe away with a clean rag.
- Remove the Dirty Filter
- Carefully twist and pull the filter off its cage. Avoid knocking dirt into the air boot.
- Inspect – Clean the Air Boot
- Check for sand or dust. Clean with a contact cleaner (do not saturate) – wipe thoroughly.
- Wash the Foam Filter
- Submerge the foam filter in a cleaning solution specifically for air filters. Gently knead – do not wring. Rinse with clean water. Let dry thoroughly.
- Oil the Filter
- Soak the dry filter in high-quality foam air filter oil. Massage the oil evenly throughout for full coverage; extra attention to seams.
- Grease the Filter Lip
- Apply a thin layer of waterproof grease around the outer sealing edge for a positive seal.
- Install the Filter
- Fit the oiled filter onto the cage, ensuring precise alignment with all mounting holes. Reinstall onto the air boot – check for a snug fit.
- Reassemble
- Replace the air cleaner case cover, shroud, and seat in reverse order. Secure all fasteners. Reconnect breather tube if needed.
Replacement Intervals – Recommendations
- Cleaning: After every major ride, especially through mud, sand, or dust.
- Replacement: Replace the filter if there is damage, loss of structure, or tearing. Consider stocking fresh, pre-oiled filters for quick swaps.
- Precaution: Always allow the cleaned filter to dry fully before oiling – never install a wet filter.
Special Considerations for the 2006 Honda CR250 Owner
- The last CR250 model year features fine-tuned chassis geometry – air intake sealing is critical, especially for competitive riding.
- Periodically check the sealing surface and airbox for wear. Replace the seat foam if it begins to degrade and let extra dust in.
- Always use foam-specific filter oil or Honda's recommended product. Avoid engine oil or non-foam oils that may cause filter deterioration.
- This era of Honda two-strokes responds sensitively to clean air – neglecting your filter leads to faster ring and piston wear.
