The air filter on your 2015 GAS GAS TXT-PRO-250 is critical for keeping dirt and debris out of the engine, ensuring long-lasting performance on the toughest trials courses. Regular cleaning – and occasional replacement – is required to protect your bike's engine and maintain peak power delivery.

Recommended Cleaning – Replacement Schedule

  • Clean the air filter after every race or ride, particularly in dusty or muddy environments. Frequent cleaning helps prevent clogging and poor throttle response.
  • Replace the air filter if it is damaged, excessively worn, or fails to fit snugly in the airbox. Inspect after each cleaning for tears, thinning foam, or hardening material.

Step-by-Step Air Filter Removal

  1. Turn off the engine and allow it to cool.
  2. Remove the seat and side panels to access the air filter box.
  3. Carefully unclip – or unscrew – the air filter box cover. Set aside all fasteners.
  4. Gently take out the air filter, being careful not to knock loose debris into the intake tract.

Cleaning Procedure

  1. Tap the filter lightly to remove loose dirt.
  2. Wash the filter in a dedicated filter cleaning solution or mild, soapy water. Do not use gasoline – it can damage the filter material.
  3. Rinse thoroughly with clean water until no dirt remains. Repeat steps if necessary.
  4. Allow the filter to dry fully – avoid using direct heat or sunlight.
  5. Apply high-quality foam air filter oil, massaging it through the entire element to ensure complete coverage.

Installation – Final Checks

  1. Wipe the air box clean of any dirt or residue.
  2. Reinstall the air filter, ensuring correct orientation and a snug fit with no air gaps.
  3. Secure the air filter box cover and replace the seat and side panels.
  4. Start the bike and check for any abnormal engine sounds or warning indicators.

Model Notes – 2015 GAS GAS TXT-PRO-250

  • This trials bike uses a high-flow foam air filter designed for rapid cleaning – perfect for the frequent maintenance schedule typical of competitive trials riding.
  • The fit and seal of the air filter are crucial. Aftermarket or non-OEM filters may compromise protection – always test-fit before riding.
  • The TXT-PRO-250 is renowned for reliability, but dust entering the intake can lead to difficult starting, reduced power, or engine damage. Vigilant air filter maintenance is especially important.
  • Always check for intact seals between the filter and airbox to prevent bypass issues, which can silently damage your engine over time.

Troubleshooting Tips

  • If you notice poor throttle response or unusual engine noise after cleaning, double-check filter installation – air leaks or loose fitment can allow debris into the engine.
  • Persistent dirt on the filter after short rides may indicate a damaged intake seal or excessively dusty riding conditions. Inspect the entire airbox and consider more frequent cleaning.

Proper maintenance of your air filter protects your investment – and keeps your 2015 GAS GAS TXT-PRO-250 performing at its best on every ride.
