Air Filter Cleaning & Replacement Guide for 2013 Yamaha TTR50
Shop parts for a 2013 Yamaha TTR50 Dirt Bike.
The air filter in the 2013 Yamaha TTR50 is a vital component for ensuring engine longevity – regular maintenance keeps performance consistent and helps avoid costly repairs. The TTR50 uses a compact foam filter, which requires careful attention due to its small size and the high likelihood of debris accumulation during off-road rides. If you ride in dusty or wet conditions, clean or replace the air filter even more frequently than standard service intervals recommend.
How Often to Clean or Replace
- Inspect and clean the air filter at every second ride or at intervals listed in the maintenance schedule, whichever is more frequent, especially in dusty environments.
- Replace the air filter whenever it's visibly damaged or overly dirty – these small foam filters are both affordable and easiest to replace completely when worn out.
Tools & Supplies Needed
- Phillips head screwdriver
- Air filter cleaning solvent (never gasoline or any low flash point solvent)
- Air filter oil
- Disposable gloves
- Replacement air filter (if necessary)
Step-by-Step Cleaning Instructions
- Remove the air filter cover: Locate the three screws securing the air filter case cover and carefully remove them.
- Extract the filter: Gently pull out the foam air filter and mesh from the housing.
-
Clean the filter:
- Foam Element: Rinse thoroughly in dedicated parts cleaning solvent, then gently squeeze out excess without twisting or wringing.
- Mesh Material: Clean with solvent and wipe dry.
- Let the filter dry completely before re-oiling; do not use heat to speed up drying.
- Oil the filter: Apply air filter oil evenly to the foam. The goal is full coverage without oversaturating – a slightly tacky, not dripping, filter is ideal. Place the filter in a plastic bag to distribute the oil, then gently squeeze out excess.
- Reinstall: Insert the oiled filter back in the airbox, followed by the mesh if equipped. Replace the cover and secure all screws.
Replacement Procedure
- Follow removal steps above.
- Insert a new foam air filter (replacement is recommended if the foam is torn, heavily stained, or fails to clean thoroughly).
- Oil as described and reinstall into the airbox.
Model-Specific Notes for the 2013 Yamaha TTR50
- Filter Size: The TTR50 uses a small foam filter, making it essential to clean more often than larger capacity bikes.
- Frequent Cleaning: Clean every second ride to avoid premature engine wear, especially since young riders may encounter varied terrain.
- Chain Adjustment: After filter service, check the chain free play (35–45 mm) and adjust as needed – stretching is normal on newer chains.
- Safe Disposal: Dispose of used oil and filters in an environmentally responsible way.
Final Tips
- Always park the bike securely before servicing.
- Check the drain tube for debris – a blocked tube can cause water or mud to back up into the airbox.
- Never operate the TTR50 without a properly installed, oiled filter – doing so risks damaging the engine permanently.
