Air Filter Cleaning – Replacement Guide for 2017 Yamaha PW50
Shop parts for a 2017 Yamaha PW50 Dirt Bike.
The 2017 Yamaha PW50 is revered for its simplicity and reliability, making routine air filter maintenance essential for preserving performance and ensuring maximum lifespan for young riders' first dirt bike adventures. Proper cleaning – and timely replacement – of the PW50's air filter is especially important given this model's two-stroke engine, which is highly sensitive to dust, dirt, and debris intake.
Understanding the 2017 PW50 Air Filter
The factory air filter in the 2017 Yamaha PW50 is a foam type, designed for dual-stage filtration. The coarse outer layer traps larger particles, while the finer inner layer captures smaller contaminants, keeping your engine breathing clean air without restricting flow. Using quality replacements or cleaning methods that maintain these layers is critical for peak engine health and power delivery.
When to Clean vs. Replace
- Clean the air filter after every 2-3 rides in dry or dusty conditions, or at least once a month during regular use.
- Replace the air filter when you notice excessive wear, tears in the foam, permanent staining, or a significant loss of structure after cleaning sessions.
Proprietary MotoSport PW50 Air Filter Cleaning Procedure
- Remove the Side Panel – With a 12mm socket, loosen and remove the two bolts at the rear of the plastic right-side panel.
- Open the Air Filter Box – Locate the Philips-head screw securing the air box to the carb elbow; loosen it and carefully slide the air box back to expose the air filter.
- Extract the Air Filter – Gently remove the foam filter, inspecting for rips, worn foam, or fuel/oil saturation.
- Clean the Filter – Soak the foam in a bucket of warm water with mild detergent. Squeeze (do not wring or twist) until all visible dirt and residue are gone. Rinse thoroughly and allow to air dry completely.
- Oil the Filter – Once dry, work a dedicated foam filter oil evenly through the filter. MotoSport recommends fully saturating the foam, then gently squeezing out any excess to avoid drippage while ensuring full dirt-trapping coverage.
- Inspect the Air Box & Intake Path – Wipe out any dust, sand, or oil that may have accumulated in the air box before refitting the filter.
- Reassemble – Re-install the filter, ensuring it sits flush on the air box's sealing lip. Secure the air box and side panel in reverse order.
PW50-Specific Air Filter Tips
- The 2017 PW50's air box is compact but must be sealed completely to prevent dirt ingress. Always inspect the sealing surface for warping or damage.
- If you ride in extremely muddy or sandy environments, consider pre-filter covers for added engine protection.
- Using genuine or high-quality replacement filters ensures longevity and correct fitment. Aftermarket dual-stage foam filters with durable adhesive are preferred for their long-lasting performance and easy cleaning cycles.
Replacement Process for Worn or Damaged Filters
- Ensure the new filter is dual-stage foam, shaped specifically for the PW50. Avoid paper or gauze-style filters, which do not offer the same dust holding capacity or engine protection for this model.
- Pre-oil the new filter before installation for maximum protection from the very first ride.
Why Air Filter Care Matters for Your 2017 Yamaha PW50
Neglecting the air filter can drastically shorten engine life, reduce throttle response, and cause poor starting. The PW50's two-stroke engine is particularly vulnerable to air intake blockage or contamination, making routine filter care one of the most important jobs for every owner.
Keep your 2017 Yamaha PW50 running strong by making air filter cleaning and replacement a core part of your maintenance routine.
