Shop parts for a 2014 Yamaha TW200 Dirt Bike.

The 2014 Yamaha TW200 is well-known for its bulletproof reliability, but consistent air filter maintenance directly impacts its longevity & trail performance. This guide from MotoSport is tailored specifically for 2014 TW200 owners to ensure proper airflow, optimal engine protection, and consistent power delivery—whether you're trail riding, commuting, or exploring rough terrain.

Recommended Service Intervals

  • Inspect and clean the filter every 3,000 miles, or more often in dusty, muddy, or wet conditions.
  • Replace the air filter immediately if it's damaged or heavily soiled.

Tools and Supplies You'll Need

  • Phillips screwdriver
  • Foam air filter oil – never use motor oil
  • Biodegradable cleaner or mild detergent
  • Clean water
  • Clean, lint-free towels
  • Vacuum grease (optional – for sealing edges)
  • Magnetic bolt pan (helpful to keep track of hardware)

Removing the Air Filter

  1. Turn off engine and ensure motorcycle is cool to the touch.
  2. Remove the left side panel by unscrewing the two Phillips screws. Pull the panel outward to unsnap it from the grommet.
  3. Unscrew the four airbox cover screws (these are longer than the side panel screws; keep sets separate to avoid mixing them).
  4. Remove the airbox cover. The air filter is housed on this panel; gently pull off the filter. Note any metal cage or filter bracket and set aside.

Inspection – When to Replace

  • Check for tears, holes, or thinning in the foam. Replace the filter if any are found.
  • If excessively dirty from oil, sand, or water, a replacement is advised for best engine safety.

Cleaning Your TW200 Air Filter

  1. Separate the foam filter from any plastic or metal cage.
  2. Wash with a mild detergent or dedicated foam air filter cleaner. Gently squeeze out dirt but do not wring out the foam—this can damage it.
  3. Rinse thoroughly with cool water.
  4. Allow filter to dry fully before oiling. Do not use compressed air or direct heat.

Oiling and Reinstalling the Air Filter

  1. Apply foam filter oil evenly, massaging it into all pores. Excess oil should be gently squeezed out – a filter that's too oily attracts extra dirt.
  2. Optional: Apply a thin layer of vacuum grease to the air filter's sealing flange for extra dirt protection.
  3. Reinsert the filter onto the airbox cover, aligning it with the housing tab and any support cage.
  4. Reattach the airbox cover (4 screws), then the side panel (2 screws). Ensure all fasteners are properly tightened without overtightening.

Special Tips for the 2014 Yamaha TW200

  • The TW200's airbox is well-protected but can be overwhelmed in heavy mud or deep water—inspect the filter after any river crossings or especially dusty rides.
  • Pay close attention when reinstalling the panels: the airbox screws are longer than the panel screws. Mixing them can strip threads or leave panels loose.
  • If installing aftermarket filters (e.g., UNI foam), always oil them before their first use and check fitment against the airbox gasket for a complete seal.

Proprietary MotoSport Expertise

  • A well-maintained foam air filter is key to the TW200's legendary dependability. Sticking to a cleaning & replacement schedule ensures your engine breathes clean, maximizes power, and avoids premature wear.
  • Always use foam-specific filter oil for the 2014 TW200, and note that many aftermarket high-flow filters require slightly more frequent servicing.
