Maintaining your 2020 Yamaha TW200 air filter is essential for optimal engine performance and a long, trouble-free ride. This MotoSport.com proprietary guide covers step-by-step cleaning and replacement instructions, tips specific to the TW200 design, and best practices for keeping your machine at its best.

How Often Should You Clean or Replace the Air Filter?

  • Clean the air filter every 3,000 miles or sooner if you frequently ride in dusty or wet conditions.
  • Inspect visually: If the filter is torn, severely stained, or damaged, replace it immediately for optimal protection.

What Makes the 2020 TW200 Air Filter Unique?

  • The TW200 uses a foam air filter with a sturdy internal cage for precise fitment.
  • The airbox is well-sealed but still accessible, with the filter positioned on the left side for quick servicing.
  • OEM and aftermarket filter options are available–oil type must be appropriate for foam material.

Tools & Supplies You'll Need

  • Phillips screwdriver
  • Air filter cleaner (for foam filters) – avoid petroleum-based solvents
  • Warm water and mild soap (dish soap is suitable)
  • Dedicated air filter oil for foam filters
  • Non-lint towels or paper towels
  • Latex or nitrile gloves to keep hands clean (optional)

Step-by-Step: Removing the Air Filter

  1. Locate the filter on the left side of your TW200.
  2. Use a Phillips screwdriver to remove the two screws on the side panel, then gently pull the panel from the grommet at the top.
  3. Remove four screws securing the airbox cover and set the cover aside.
  4. Carefully remove the filter from the cover, separating it from the internal plastic cage. Inspect for damage or tears; if present, replace the filter.

Cleaning Your Foam Air Filter (TW200 Procedure)

  1. Gently tap the filter to remove loose dirtalways tap dirt side down to avoid contaminating the clean engine side.
  2. Soak the filter in a solution of mild soap and warm water. Squeeze (never wring or twist aggressively) to release dirt. Rinse thoroughly with clean water.
  3. If the filter is especially dirty, repeat the process. Commercial foam filter cleaners can also be used.
  4. Let the filter air dry completely. Do not use compressed air or heat sources, as this can damage the foam.
  5. Once dry, apply foam filter oil generously–work it in by hand to ensure full and even coverage, inside and out.

Installing the TW200 Air Filter

  1. Mount the clean, oiled foam filter back onto the filter cage, making sure the fit is snug and even.
  2. Attach the filter to the airbox cover and then reinstall the airbox cover, securing with all four screws. Be careful not to overtighten to avoid stripping the threads.
  3. Refit the left side panel by lining up the grommet and reinstalling the two main screws.

Extra Tips for TW200 Owners

  • OEM filter oil is recommended for longevity and correct filtration, but premium foam filter oils will also work well.
  • Before opening the airbox, wipe down the area around the cover to prevent loose grit from falling into the air intake.
  • Mileage may vary: Consider more frequent cleaning if you ride in especially dusty or muddy terrain, or after water crossings.
  • Treat the filter cage gently; damage to this piece can compromise seal and filter performance.

Regular maintenance of your 2020 Yamaha TW200 air filter extends the life of your engine and enhances throttle response, fuel economy, and reliability. Allowing a dirty or damaged filter to remain in service can result in costly engine repairs–making periodic inspection as important as regular oil changes. For replacement filters, airbox hardware, or filter oils specific to your bike, choose tested, high-quality options from MotoSport.
