Shop parts for a 2017 GAS GAS TXT-PRO-RACING-280 Dirt Bike.

The 2017 GAS GAS TXT-PRO-RACING-280 is an elite trials bike, known for its lightweight construction, responsive 272.2cc 2-stroke engine, and precision handling. Regular air filter maintenance is critical for peak performance, smooth throttle response, and prolonging your bike’s engine life. Following this exclusive MotoSport.com guide ensures your machine keeps running strong on any line you take.

Why Regular Air Filter Maintenance Matters

  • Maximum Engine Protection: A clean air filter prevents dust, grit, and debris from entering the engine, reducing wear on internal parts.
  • Consistent Performance: Trials bikes like the TXT-PRO-RACING-280 demand crisp throttle response, which dirty filters can hinder.
  • Longer Service Intervals: A well-maintained filter extends the life of your engine’s top end and reduces the frequency of rebuilds.

Unique Air Filter & Airbox Features on the 2017 TXT-PRO-RACING-280

  • The bike features a creatively engineered airbox that is compact yet allows for easy filter changes–typically only requiring removal of one bolt to access the filter, making routine service quick and rider-friendly.
  • This model uses a high quality foam filter (commonly by Twin Air), engineered for top-level dust filtration with minimal airflow restriction.

How to Remove the Air Filter

  1. Remove the seat and side cover, which may require a single fastener or quick-release tabs.
  2. Locate the airbox cover. On the 2017 TXT-PRO-RACING-280, removal typically involves one retaining bolt or screw. Gently lift off the cover.
  3. Carefully pull out the air filter. Pay attention to its orientation for correct reinstallation.

Cleaning the Air Filter Step-by-Step

  1. Tap the filter gently to remove loose dirt. Avoid knocking too hard, as this can damage the foam.
  2. Apply an air filter-specific cleaning solution or mild dish soap diluted in warm water. Massage the filter thoroughly and rinse until the water runs clear.
  3. Do not wring out or twist the foam, as this can split the seams. Instead, squeeze gently to remove excess water.
  4. Allow the filter to air dry completely, away from direct sun or heat sources that can deteriorate the foam.

How to Oil & Reinstall the Air Filter

  1. Generously apply foam air filter oil, working it into every pore and crease. The filter should be evenly coated but not dripping.
  2. Squeeze out any excess oil. Use gloves for this step, as filter oil can be hard to wash off skin.
  3. Inspect the inside of the airbox for any residual dust or dirt. Wipe clean with a damp cloth or paper towel.
  4. Carefully reinstall the filter in its original orientation, pressing the edges firmly into place to ensure a good seal. Reattach the airbox cover securely.
  5. Reinstall the seat and side cover.

When to Replace the Air Filter

  • Replace the filter if it shows signs of deterioration, such as tears, crumbling foam, or loose seams.
  • For frequent riders in dusty environments, keeping a spare filter on hand ensures you always have a clean one ready.

Special Notes & Model Tips

  • This model’s compact, ergonomic design makes service access easy, so air filter cleaning should be a fast job as part of your pre-ride routine.
  • Always check that the air filter is seated perfectly to prevent dirt bypass–the lightweight image of this trials bike relies on meticulous sealing and maintenance.
  • If you ride in wet or muddy conditions, inspect the filter more frequently. The airbox design resists intrusion, but checks are wise.
  • Use only high quality filter oil for maximum protection and airflow.
