Shop parts for a 2022 Yamaha PW50 Dirt Bike.
As a proud 2022 Yamaha PW50 owner, you know how crucial routine air filter maintenance is for reliable performance and engine longevity. The PW50—an iconic, rider-friendly minibike with an oil-injected two-stroke engine—thrives when its air filter is free of debris and well-oiled. Below you'll find MotoSport's proprietary step-by-step guide to keeping your PW50's air intake in optimal shape, along with special notes specific to this model year.
Why Clean or Replace the PW50 Air Filter?
- The air filter prevents damaging dust, sand, and debris from entering your engine while maximizing airflow for smooth throttle response.
- Neglect leads to poor performance, hard starting, and engine wear.
- The 2022 PW50's foam air filter requires regular attention, especially in dusty conditions or after extended riding sessions.
How Often Should You Service the Air Filter?
- Yamaha recommends inspecting and servicing the air filter every 5-10 hours of use. Clean more frequently if riding in especially dusty environments.
- Replace the filter if there are any signs of tearing, foam degradation, or persistent clogging.
Tools & Supplies Needed
- Phillips screwdriver (preferably #3 size)
- 12mm socket for side panel bolts
- Foam air filter cleaner or mild detergent
- Clean water
- Foam air filter oil
- Clean, lint-free cloths
- Optional: contact cleaner for the airbox interior
- Replacement air filter (if damage or age is present)
PW50 Air Filter Cleaning & Replacement Process
-
Remove the Side Panels
Use a 12mm socket to unscrew the two rear bolts on the side plastic panel for access to the air filter assembly. -
Access the Air Filter
Locate the air filter cover near the left rear shock. Using a #3 Phillips screwdriver, remove the center screw holding the cover.
For PW50 models, gently press down on the kickstarter to free the cover if it feels snug. -
Inspect the Filter
Remove the foam filter. Check for excess dirt, oil buildup, or any tears and crumbling. Replace the filter if you see physical deterioration. -
Clean the Filter
Wash the filter thoroughly in warm, soapy water (using a cleaner specifically formulated for foam air filters is best). Rinse well and gently squeeze out the water.
Avoid wringing, which can tear the foam. -
Dry Completely
Allow the filter to air dry fully, out of direct sunlight. -
Re-Oil the Filter
Apply foam air filter oil evenly and work it into the filter. Squeeze out any excess oil to prevent over-saturation. -
Clean Airbox Area
Wipe out any dust or debris from the airbox using a damp, lint-free cloth and contact cleaner if needed. -
Reinstall
Insert the clean, oiled filter back into position. Ensure it seats evenly for a proper seal.
Reattach the cover and secure with the Phillips screw. Replace the side panels and tighten the bolts.
Model-Specific Tips for 2022 Yamaha PW50 Owners
- The PW50 uses a simple, non-sealed foam filter. If cleaning with fuel, remove rubber components to prevent hardening over time.
- Be especially careful reseating the filter; a poorly sealed filter can allow unfiltered air and cause premature engine wear.
- The kickstarter may slightly obstruct airbox access–pressing it down gently allows easier removal of the filter cover.
- Frequent cleaning is necessary due to the PW50's popularity with new riders and frequent use in sandy or dusty riding conditions.
When to Replace the Air Filter
- If the filter foam feels brittle, crumbles, or has visible holes or tears, it's time for a new one. Persistent clogging or discoloration after cleaning is also a sign to replace.
- Always use a PW50-specific replacement filter for best fit and protection.
Proprietary MotoSport Air Filter Service Checklist
- Remove plastics – don't force panels to prevent cracking plastics or mounting tabs.
- Clean inside the airbox every service – dirt accumulation in the airbox can lead to filter sealing issues.
- Let filters dry and "air out" after oiling, for at least 15-20 minutes before installation. This helps excess oil evaporate, reducing the chance of filter oil being sucked into the carburetor.
- Keep extra clean filters on hand for long riding weekends or races to ensure best performance and convenience.
