Shop parts for a 2007 Yamaha TTR50 Dirt Bike.

Proper maintenance of your 2007 Yamaha TTR50 air filter safeguards engine life, improves performance, and ensures a fun, trouble-free riding experience. This MotoSport.com exclusive guide explains precise cleaning – replacement steps, tailored to the TTR50's unique design. Critical notes and best practices for this model are included.

Why Clean – Replace Your Air Filter?

  • Dust and debris protection: The TTR50 is often ridden by beginners in rugged environments where filter clogging can happen quickly. A clean filter prevents harmful particles from entering the engine.
  • Engine efficiency: A clogged filter robs power and increases wear.
  • Model-specific note: The TTR50's air filter sits higher off the ground compared to similar bikes, keeping it cleaner longer, but regular inspection is still essential.

Recommended Service Interval

  • Inspect and clean the air filter at intervals specified in your owner's manual, or more often in dusty or wet conditions.
  • Replace the filter if damaged, excessively dirty, or if performance isn't restored after cleaning.

Tools – Supplies Needed

  • Phillips screwdriver
  • Dedicated parts cleaning solvent (never use gasoline – fire hazard)
  • Air filter oil (foam filter specific)
  • Clean rags
  • Nitrile gloves

How to Remove the Air Filter

  1. Ensure the TTR50 is parked securely.
  2. Remove the air filter case cover using a screwdriver to unscrew the three bolts.
  3. Carefully extract both the sponge (foam) element and mesh screen from the case.

Cleaning the Filter

  1. Gently wash the sponge element in a recommended cleaning solvent. Do not twist or wring the foam. You may gently press and squeeze out the solvent.
  2. Rinse the filter element in warm water for thorough cleaning.
  3. Let the filter air dry completely – never apply heat or use a hair dryer.
  4. Clean the mesh screen with solvent and wipe dry.

Oiling the Filter

  1. Thoroughly saturate the foam element with air filter oil. Ensure the filter is wet but not dripping; excessive oil can get pulled into the airbox and affect starting.
  2. Massage and squeeze out excess oil. On this model, too much oil may drain into the breather tube or affect starting, so balanced oiling is key.

Reinstallation

  1. Re-insert the air filter mesh and saturated foam into the case, ensuring an even and snug fit. If the mesh screen was removed, verify it is correctly replaced.
  2. Wipe down the inside of the airbox with a clean rag before reassembly to remove residual dust.
  3. Reinstall the air filter cover securely using the three bolts.

Replacement Instructions

  • If the foam is torn, degraded, or does not clean properly, install a new filter from MotoSport.com.
  • Always properly oil new foam filters before installation.
  • Verify the mesh screen is present – this helps maintain filter shape and function.

Additional TTR50 Model Notes

  • The higher placement of the air filter reduces direct dirt impact, but does not eliminate the need for cleaning, especially after crashes or extended off-road riding.
  • The TTR50 filter is more compact than on adult models, so light dirt buildup can still quickly affect performance.
  • Be cautious not to over-oil the filter; symptoms such as hard starting may indicate excess oil has pooled in the breather system.

Environmental – Safety Reminders

  • Dispose of used solvent, oil, and old filters responsibly.
  • Use gloves and work in a well-ventilated area.
