Air Filter Cleaning – Replacement Guide for 2024 GAS GAS TXT Racing 250

Shop parts for a 2024 GAS GAS TXT Racing 250 Dirt Bike.

The 2024 GAS GAS TXT Racing 250 stands apart as a champion-grade trials bike, featuring a super-slim chassis and an ingeniously designed airbox that provides both high performance and easy maintenance. The air filter is central to keeping the engine at peak condition, and regular cleaning – or replacement – is essential for optimal performance and longevity. Below, MotoSport provides the proprietary, step-by-step process and important model-specific notes for TXT Racing 250 owners.

Why Air Filter Care Is Critical for the TXT Racing 250

  • Performance First: The airbox is compact and cleverly engineered for quick access, making filter maintenance more straightforward than on most bikes. A clogged or dirty filter dramatically reduces engine response and power output.
  • Engine Protection: Trials riding means dust, mud, and debris are constant threats. Neglecting the air filter can lead to engine contamination – and costly repairs.
  • Model-Specific Access: For the 2024 TXT Racing 250, GAS GAS uses a top-quality Twin Air filter housed within an airbox held together securely but simply, by a single bolt. This makes access tool-efficient, minimizing downtime between rides.

Preparation – What You Will Need

  • Replacement Twin Air filter or OEM filter (if swapping)
  • Air filter cleaner and air filter oil, both compatible with foam filters
  • Basic hand tools for the single securing bolt
  • Clean rags and gloves

How to Remove the Air Filter

  1. Access the airbox: Locate the airbox just beneath the seat and side plastics. Due to the minimalist design, you do not need to remove excess hardware – only what provides direct access.
  2. Undo the securing bolt: The filter is fastened by one bolt. Remove this bolt carefully and set it aside.
  3. Extract the filter: Gently pull out the filter-frame assembly from the airbox. Take note of how the filter fits for easier reinstallation.

Cleaning Instructions

  1. Inspect for damage: Examine the filter for tears or compromised foam. Replace if needed.
  2. Pre-clean: Tap the filter gently to dislodge large debris.
  3. Apply foam filter cleaner: Soak the filter thoroughly and massage cleaner into the foam. Never use fuel or harsh solvents, as these damage filter adhesives.
  4. Rinse safely: Wash the filter in lukewarm water until clean. Repeat if necessary. Squeeze (do not wring) out excess water.
  5. Dry fully: Allow the filter to air-dry completely before oiling.

Oiling – Reinstallation

  1. Oil application: Apply specific foam filter oil. Massage the oil thoroughly for even coverage, but do not over-saturate.
  2. Re-fit the filter: Place the filter assembly back into the airbox, aligning it as found during removal.
  3. Secure with the bolt: Tighten the single securing bolt finger-tight, then snug it with your tool. Avoid overtightening.
  4. Final check: Ensure no gaps around the airbox seal. Wipe away any spilled oil and confirm airbox is correctly closed.

When to Replace the Air Filter

  • If the filter is torn, degraded, or does not come clean after washing
  • After repeated hard rides in extreme dust or wet conditions
  • At minimum, replace every riding season or as manufacturer suggests

Model-Specific Ownership Tips

  • One-bolt System: GAS GAS TXT Racing 250's single-bolt airbox design makes maintenance notably faster—never skip routine checks, as you have no hardware excuses.
  • OEM Quality: Always use a GAS GAS-approved filter or directly equivalent foam filter for correct fit and airflow.
  • Bodywork Caution: The slim Polypropylene body plastics are flexible, engineered to withstand impacts and bend without breaking, but handle them carefully when accessing the airbox to avoid unnecessary tension.
  • Ergonomics: Filter changes do not affect ergonomics or fuel tank placement; the 2.4-liter fuel tank sits separately and is also tool-accessible via a single bolt.

The 2024 GAS GAS TXT Racing 250 was designed with rider maintenance in mind. With just a single bolt between you and a clean air filter, keeping your trials machine running strong is easier than ever.
