The 2019 Husqvarna TX300 is a two-stroke cross-country machine renowned for its potent power delivery and reliability. Proper air filter maintenance is critical for peak performance, engine longevity, and consistent throttle response, especially in dusty or sandy riding environments. Below you'll find a proprietary MotoSport guide tailored specifically for your 2019 TX300.

Why Air Filter Care Matters for the TX300

  • High-performance engines like the TX300 rely on a clean air filter to prevent dust, sand, and debris from entering the intake.
  • Failure to maintain the air filter can lead to premature engine wear and power loss.
  • This model features two filter screens that add an extra layer of protection – be sure to inspect and care for these screens during routine maintenance.

Proprietary Step-by-Step Cleaning Guide

  1. Remove the air filter:
    • Access the filter by releasing the seat using the quick-release mechanism typical to Husqvarna designs.
    • Unfasten the filter cage and carefully extract the filter, minimizing contact with internal airbox surfaces.
  2. Inspect the filter:
    • Check for visible tears, dirt buildup, and oil saturation.
    • Never reuse a damaged filter — replace immediately to protect your engine.
  3. Clean the filter:
    • Use a proprietary MotoSport air filter cleaner for best results.
    • Submerge and agitate the filter in cleaning solution; avoid wringing or twisting as this can cause damage.
    • Rinse in clean water and let the filter dry fully in a dust-free area.
  4. Oil the filter:
    • Apply MotoSport recommended filter oil evenly throughout the filter foam.
    • Massage the oil into the foam, ensuring complete coverage without pooling excess oil.
  5. Inspect and clean filter screens:
    • The TX300 includes two filter screens – gently remove and clean these as part of your routine.
    • Check for trapped debris and ensure the screens are free from tears or cracks before reinstalling.
  6. Reinstall the filter:
    • Seat the filter properly in the cage – make sure the filter fits snug without gaps.
    • Replace the filter cage; secure the seat; ensure a tight airbox seal to prevent unfiltered air from entering.

When to Replace the Air Filter

  • Replace your filter if you notice significant tears, thinning, or damage after inspection.
  • If riding in extremely dusty, wet, or sandy conditions, inspect and clean your filter after each ride; replace it if needed.
  • Stock up on replacement filters for quick swaps between races or long weekends. – MotoSport stocks direct-fit filters and all necessary airbox components specific to the 2019 TX300.
