Understanding the Airbox Design

Proprietary MotoSport Air Filter Maintenance Procedure

Preparation

  • Start with a clean, well-ventilated workspace.
  • Have MotoSport air filter cleaner and air filter oil on hand, along with disposable gloves, a soft brush, and a lint-free towel.

Removal Steps

  • Remove the seat and side panel for direct access to the airbox area.
  • Locate the single air filter retaining bolt inside the airbox. Unscrew and set aside the bolt and washer.
  • Carefully slide out the filter. Inspect for tears, heavy soiling, or signs of deterioration.

Cleaning Steps

  • Tap the filter gently to dislodge loose dirt.
  • Apply air filter cleaner and let it soak according to MotoSport guidelines.
  • Rinse with lukewarm water from the inside out to avoid embedding debris further, then gently squeeze out excess water. Do not wring or twist as this can damage the foam.
  • Let the filter dry completely in a dust-free environment.

Oiling & Reinstallation

  • Once dry, evenly apply MotoSport-approved air filter oil to the foam. Massage the oil into the filter to ensure uniform coverage, paying extra attention to seams and edges.
  • Reinstall the clean, oiled filter into the airbox. Secure with the retaining bolt, ensuring proper alignment and sealing.
  • Reassemble the seat and side panel.

Replacement Guideline

  • Inspect the air filter after every dusty or wet ride. Replace the filter at the first sign of permanent deformation, tearing, or if cleaning does not restore it to like-new condition.

Model-Specific Notes

  • The unique shape and fit of the GAS GAS TXT-PRO-RACING-300 airbox require filters specific to this model. Using the correct filter ensures optimal fit and protection.
  • This model’s airbox design is highly accessible—a single bolt removal means you can carry a spare filter to events and swap it within minutes.
  • The compact fuel tank and bodywork are designed around the airbox, so always re-check side panel and seat installation to avoid pinching wiring or the filter itself.*
