Shop parts for a 2020 Yamaha TTR50 Dirt Bike.

Maintaining your 2020 Yamaha TTR50 air filter is essential for optimizing engine performance and longevity. The air filter prevents dirt, dust, and debris from entering the engine, making routine cleaning and replacement a must for every owner – especially if riding in dusty or wet environments.

How Often Should You Clean or Replace the Air Filter?

  • Follow the maintenance intervals in your owner's manual, but clean or replace more frequently if you ride in particularly dusty or muddy areas.
  • Signs the air filter needs attention: visible dirt, reduced power, or noticeable engine hesitation.

What You Need

  • Phillips head screwdriver
  • Parts cleaning solvent (do not use gasoline or flammable solvents)
  • Recommended air filter oil
  • Replacement air filter (if needed)
  • Clean gloves

Air Filter Removal

  1. Make sure the bike is securely parked and cool.
  2. Remove the air filter case cover by unscrewing the screws with a Phillips head screwdriver.
  3. Carefully pull out the sponge material and filter mesh.

Cleaning the Air Filter

  • Mesh: Clean with parts cleaning solvent. Wipe off all solvent thoroughly.
  • Sponge (foam): Gently clean with solvent, then squeeze out excess (never twist or wring – this may damage the foam).

Important: Never use gasoline or low flash point solvents. Handle the foam carefully to avoid tears.

Oiling the Air Filter

  1. Apply recommended air filter oil evenly across the entire foam surface.
  2. Squeeze out any excess oil so the filter is saturated but not dripping.

Don't oversaturate – excess oil may restrict airflow and clog the filter.

Reinstallation

  1. Place the clean, oiled filter (and mesh) back into the airbox.
  2. Secure the air filter case cover with screws.
  3. Inspect and clear any drain tubes attached to the air box for debris.

Replacement Tips Specific to the 2020 Yamaha TTR50

  • The TTR50 uses a foam air filter element – service it gently to avoid tearing.
  • Filters are affordable and designed for frequent replacement; consider using a new filter if the foam feels brittle or does not clean up well.
  • Always dispose of used oil and filters in an environmentally safe manner.

What Makes the TTR50 Unique?

  • This model's filter location makes access simple – just three screws to remove for service or replacement.
  • The small engine is sensitive to airflow restriction – regular filter maintenance makes a noticeable difference in throttle response.
  • If you ride in wet or muddy conditions, inspect and clean your filter after every ride.

Quick Safety Note

Never operate your TTR50 without a filter installed. Unfiltered riding can cause catastrophic engine damage.
