Why Air Filter Care Matters on the 2022 TXT-Racing-300

  • Trials bikes like the TXT-Racing-300 are frequently exposed to dust, sand, and water splashes.
  • A clean air filter is essential for consistent engine response, especially in technical terrain where precision matters.
  • The TXT design uses a foam element filter that is easily serviceable, but requires proper sealing to prevent unfiltered air from entering the intake.

How Often to Service Your Air Filter

  • Clean and re-oil the filter every ride in dry, dusty, or muddy conditions.
  • For occasional use in cleaner environments, check at least every three rides or after extended transport in dusty areas.
  • Inspect after every race or event to prevent performance loss from a clogged filter.

Tools & Supplies You Will Need

  • Air filter-safe cleaning solvent or mild soap & water
  • Fresh air filter oil (foam filter compatible)
  • Clean rags
  • Rubber gloves
  • Replacement air filter (if installing new)

Step-by-Step Air Filter Removal & Cleaning

  1. Remove the Seat and Filter Cover: Release the seat latch and lift the seat off. Locate and unscrew the filter box cover fasteners to access the filter compartment.–2021 Owner's Manual
  2. Remove the Filter: Grasp the filter frame and gently remove the entire assembly, being careful not to dislodge dirt into the airbox.–2021 Owner's Manual
  3. Inspect the Air Boot: Wipe the airbox area with a damp rag. For large debris, vacuum gently. Avoid letting any loose dirt fall inside.
  4. Clean the Filter: In a well-ventilated area, clean the foam filter using air filter cleaner or mild soap, rinsing thoroughly until water runs clear. Squeeze (do not wring) to avoid tearing the foam.
  5. Dry the Filter: Allow the filter to air dry completely. Avoid using heat sources that may damage the foam.
  6. Apply Air Filter Oil: Massage high-quality foam filter oil evenly throughout the filter, ensuring complete coverage – any dry spots may allow dirt ingress.
  7. Inspect the Filter Seal: Check that the rubber sealing edge is undamaged. Minor cracks or tears warrant filter replacement.

Reinstallation – The Right Way

  1. Install the Filter: Carefully fit the oily filter and frame into the airbox, aligning it precisely on the seal surface. Gently press to seat the filter – the TXT-Racing-300 relies on an airtight fit for optimal filtration.–2021 Owner's Manual
  2. Reinstall the Air Filter Box Cover: Fasten securely to keep dust and debris out.
  3. Refit the Seat: Make sure it latches tightly to avoid rattling or accidental dislodging during riding.

Replacement Tips – When to Use a New Filter

  • If the foam is torn, excessively stained, or the seal is compromised, swap the air filter for a new one.
  • Always keep a spare, properly oiled filter ready for quick changes at the trail or event.

Model-Specific Notes for the 2022 GAS GAS TXT-Racing-300

  • Pay special attention to the air filter mounting orientation; an off-center install can cause dust leaks leading to accelerated engine wear.
  • TXT models are engineered for quick airbox access, but seals must be inspected every service – trials-focused bikes often experience more direct splash and debris.
  • Ensure the airbox drain is free of mud after deep water crossings.

Frequent filter care is the most effective step for protecting your TXT-Racing-300, maintaining peak performance for trials competition or spirited riding. Trust this MotoSport.com guide to keep your air intake & engine running clean, and remember, quality air filter oil and parts ensure the best results.
