Shop parts for a 2022 GAS GAS MC85 Dirt Bike.
The air filter in your 2022 GAS GAS MC85 plays a vital role in engine performance and longevity. Regular cleaning – as well as inspection – is necessary to maintain peak power, whether you're hitting the track or trailing through dust and mud.
Why Air Filter Care Matters on the MC85
This 85cc two-stroke is designed for competitive youth motocross, meaning it operates at high RPMs and demands clean airflow for optimal combustion. Dirty or clogged filters can reduce power, accelerate engine wear, and even cause costly damage. Proper air filter care ensures safety and reliability — and helps riders get the most from this model's high-revving engine.
Unique Features of the 2022 GAS GAS MC85 Air Filter System
- Tool-less filter access using the dedicated air filter box cover, making removal fast & simple for regular maintenance.
- Standard foam filter element designed for easy cleaning and maximum filtration.
- The MC85 air filter is highly exposed due to the bike's open frame; regular inspection is advised, especially after riding in sand or dust.
- Take care not to overtighten filter mounts, as excessive force can damage the filter or airbox seal integrity.
Step-by-Step Cleaning Instructions
-
Remove the Seat & Filter Cover
Lift the seat off by releasing the rear latch. Flip open the air filter box cover to expose the air filter element. -
Remove the Air Filter Element
Release the air filter clamp and carefully pull out the foam element. Take note of filter orientation for correct reinstallation.
Tip: Ensure no debris falls into the air intake while the filter is removed. -
Inspect the Filter
Look for rips, tears, or excessive deformation. Replace the filter if damaged. -
Clean the Filter
Wash the foam filter in a specially formulated filter cleaner or mild dish soap mixed with warm water. Squeeze — do not wring — the filter to avoid tearing.
Rinse thoroughly in clean water. -
Dry Completely
Let the filter air dry fully. Do not use compressed air or heaters, which can deform the foam. -
Apply Filter Oil
Pour a high-quality foam filter oil over the filter and massage it in for full coverage. Oil increases particle trapping and is essential for off-road use. -
Reinstall the Filter
Insert the oiled filter into the airbox in the original position. Make sure the filter seals evenly against the intake flange. -
Replace the Cover & Seat
Secure the air filter box cover and reinstall the seat. Confirm all mounts are tight.
When to Replace Your Air Filter
- Replace the filter at the first sign of physical damage, blown-out seams, or persistent dirt that won't wash out.
- Frequent riding in sand, powder dust, or wet mud accelerates filter degradation; inspect after every ride.
- MotoSport recommends keeping a spare filter on hand for race day convenience.
Proprietary MotoSport Tips for MC85 Owners
- Check the airbox for hidden debris – sand, leaves, or water – after every filter removal.
- Always re-oil and reinstall the filter immediately after cleaning to prevent dirt from entering the open intake.
- Avoid splash washing the airbox when the filter is out. Moisture here can damage the engine.
- For latest performance, inspect the rubber airbox seal – unique on MC85 – for any wear that may cause leaks.
- Never operate your MC85 without a properly installed and oiled filter, as this will void warranty and risk engine damage.
