The 2011 GAS GAS TXT-PRO-250 is a premium trials motorcycle that relies on a clean, properly maintained air filter to protect its high-revving engine from damaging dust and debris. Regular filter service not only maintains strong performance but ensures long engine life—a must for technical riding. Below, MotoSport.com provides proprietary instructions for the TXT-PRO-250 to help you clean and replace your air filter with confidence.
How Often to Service the Air Filter
- Clean the air filter after every race or ride, or more frequently in dusty environments. Replace the filter if it is damaged or showing signs of deterioration.–
- Inspect the filter for tears or weak spots every time you remove it. A compromised filter can allow debris to enter the engine, leading to rapid wear.
Tools – Supplies Needed
- Clean, filtered air
- Gloves
- Approved filter cleaner/solvent
- Filter oil (foam filter specific)
- Clean rags
- Replacement air filter (if needed)
Air Filter Removal
- Switch off the bike and allow the engine to cool.
- Remove the seat by loosening the mounting bolts at the rear.
- Unfasten the airbox cover using the side panel bolts or clips.
- Carefully detach the air filter from its housing. Observe how it is mounted for correct reinstallation.
Cleaning the Air Filter
- Gently tap the filter to release loose dirt.
- Immerse the filter in approved cleaner or warm, soapy water. Do not use gasoline or harsh chemicals as they degrade foam.
- Knead (do not wring) the filter until it is free of dirt and oil. Rinse thoroughly in clean water.
- Squeeze out excess water and allow the filter to air dry completely away from direct sunlight or heat.
Oiling the Filter
- Once dry, evenly apply foam filter oil by hand or with a plastic bag to saturate all surfaces. Do not over-oil—the filter should be moist but not dripping.
- Work the oil into every part of the foam, ensuring no dry spots remain.
Reinstalling the Air Filter
- Verify the airbox and intake boot are free of dirt or debris. Clean with a damp rag as necessary.
- Gently reattach the filter to the mounting cage, making sure it fits snugly and seals completely around the intake to block unfiltered air.
- Reinstall the airbox cover and seat securely.
When to Replace the Air Filter
- Replace immediately if the foam is torn, brittle, no longer pliable, or cannot be cleaned properly.
- Always keep a spare, pre-oiled filter ready for fast swaps at events.
Special Notes for the 2011 TXT-PRO-250 Owner
- The TXT-PRO-250 design provides quick access to the air filter for speedy maintenance. Frequent cleaning is crucial for the trials application, as dust and water can be ingested during technical sections.–
