Maintaining the air filter on your 2007 GAS GAS TXT-PRO-280 is crucial for engine performance and longevity. The TXT-PRO-280 uses a single-cylinder, liquid-cooled, two-stroke engine with crankcase reed induction, making clean air filtration absolutely essential for trials riding and optimal throttle response.

Preparation

  • Ensure the bike is cool before working.
  • Gather gloves, air filter cleaner, fresh filter oil, clean towels, and a replacement air filter if needed.
  • Remove the seat and airbox cover using standard hand tools.

Removing the Air Filter

  • Unclip or unscrew the air filter retainer from the airbox.
  • Carefully pull out the air filter, noting orientation for reinstallation.
  • Inspect the filter and airbox for excess dirt, debris, or signs of water ingress—a key concern if you regularly ride trials.

Cleaning the Air Filter

  • Fill a basin with a manufacturer-approved air filter cleaning solution.
  • Submerge the foam filter and gently compress out the dirt—never wring or twist to avoid tearing the foam.
  • Rinse with clean water until all cleaner and debris are gone, then air-dry thoroughly.
  • Clean the inside of the airbox with a damp cloth for best results.

Oiling the Air Filter

  • Apply a high-quality air filter oil to every part of the foam, but avoid oversaturating.
  • Work the oil into the foam evenly to guarantee complete coverage for dust and water protection.

Reinstallation

  • Insert the oiled filter into the airbox, making sure it seats properly for a full seal.
  • Secure the filter with the retainer and replace the airbox cover and seat.

Replacement Guidelines

  • Replace the air filter if the foam shows tears, holes, hardening, or cannot be cleaned effectively.
  • OEM replacement filters are recommended for optimal fit and life—consult MotoSport's parts catalog for compatible filter elements specifically for the 2007 TXT-PRO-280.

Key Notes for TXT-PRO-280 Owners

  • The 2007 model features a new black chassis – inspect airbox mounts as the frame finish differs from prior years.
  • The Dell'Orto PHBL26BS carburetor and hydraulic clutch setup are sensitive to airflow—regular filter maintenance improves throttle response and prevents fouling.
  • The trial-focused design means frequent filter service is necessary after muddy or dusty rides.

With consistent cleaning and timely replacement of your air filter, your TXT-PRO-280 remains responsive and protected from harmful dirt. For genuine filter elements and engine maintenance products, MotoSport has dedicated support specifically tailored to your 2007 GAS GAS TXT-PRO-280.
