Shop parts for a 2020 Yamaha PW50 Dirt Bike.
Proper air filter care is essential for your 2020 Yamaha PW50–one of the most popular youth dirt bikes thanks to its reliable shaft drive and beginner-friendly automatic transmission. Keeping the air filter clean prevents engine damage and keeps performance at its best, especially since kids often ride in dusty conditions. This guide from MotoSport.com provides all the model-specific steps you'll need, plus helpful insights unique to the PW50.
Why Air Filter Maintenance Matters for the PW50
- The PW50 uses a foam air filter element designed to trap dirt and debris before it enters the carburetor. A clogged or damaged filter can lead to poor engine performance and internal wear.
- Younger riders often drop or tip bikes, so it's important to check the air filter frequently for signs of damage or saturation.
- The PW50 air filter housing does not use a complex gasket system; the foam presses into the air box and relies on a clean, flexible fit for sealing.
Recommended Tools & Supplies
- 10mm and 12mm socket
- Phillips screwdriver
- Cleaning tub or container
- Air filter cleaner fluid (or mild detergent)
- Contact cleaner & clean rags
- Air filter oil
- Replacement air filter (if needed)
How to Remove the Air Filter on the 2020 Yamaha PW50
- Remove the seat and side cover. Use a 10mm or 12mm socket to loosen the two bolts at the back of the seat and side cover. Lift the seat and plastic cowling off to reveal the air filter housing.
- Locate and open the air filter cover. The air filter is in front of the left rear shock. Use a Phillips screwdriver to remove the single center screw in the air box cover. Gently pull the cover off. You may need to press down on the kickstarter to clear room for removal.
- Pull out the foam air filter element. Remove the foam element from the housing. Inspect the box and surrounding areas for dirt or debris. Wipe clean using a rag and contact cleaner.
How to Clean or Replace the PW50 Air Filter
- Inspect the foam element. Check for tears, holes, crumbling, or brittleness. If any are present, replace with a new filter.
- Clean the filter (if reusable). Drop the foam into a tub with air filter cleaner or mild detergent. Gently squeeze – do not wring – to remove dirt. Rinse thoroughly, then repeat with clean water. If using fuel as a cleaner (as some riders do), remove any attached rubber pieces beforehand to avoid hardening them.
- Let the filter dry completely. Allow to air dry in a clean place, away from direct sunlight or heat, which can damage the foam.
- Oil the filter. Once dry, pour air filter oil over the foam and massage in evenly. The filter should look damp throughout but not drip oil. This is crucial, as the oil helps trap the tiniest particles.
Reinstallation
- Insert the freshly cleaned or new, pre-oiled filter back into the air box, ensuring a correct fit to prevent unfiltered air leaks.
- Reinstall the air box cover and tighten the center screw securely.
- Replace the plastic side cover and seat, tightening both bolts.
- Start the engine briefly to confirm proper operation.
PW50 Owner Tips & Model Notes
- The 2020 PW50 does not use a paper or pleated filter. Always use OEM-style foam for replacements–alternate filter materials will not seal properly or could impact airflow.
- Check the air filter more often if riding in wet, sandy, or dusty environments.
- If you notice frequent clogging, check the intake tube and air box for cracks or missing pieces, as leaks are common on kids' bikes that tip over often.
- Consider keeping a spare filter with you–swapping is quick and helps prevent a missed ride.
Caring for the PW50 air filter is quick and easy, but crucial for the best riding experience. For OEM filters, cleaning kits, and expert advice, MotoSport.com has everything you need to keep your 2020 Yamaha PW50 ready for every adventure.
