Air Filter Cleaning – Replacement Guide for 2024 GAS GAS MC50

Shop parts for a 2024 GAS GAS MC50 Dirt Bike.

The 2024 GAS GAS MC50 delivers championship-winning power and performance for the next generation of riders, but keeping it running clean starts with proper air filter care. Dirty or clogged air filters starve the engine of clean air, leading to performance drop and accelerated internal wear. MotoSport.com has compiled this complete proprietary guide so you can keep your MC50 breathing freely.

Air Filter Access – MC50 Specifics

The MC50 makes filter maintenance straightforward but requires a careful approach to prevent dirt from entering the intake. Always clean the area around the filter before removing the cover. Unlike many full-size bikes, the compact airbox on the 50cc chassis means dirt can reach sensitive engine parts more easily, so attention to cleanliness is doubly important.

Required Tools & Supplies

  • Flathead screwdriver or Dzus tool (for airbox opening, as needed)
  • Clean shop towels or rags
  • Soft-bristle brush
  • Designated air filter cleaner solution
  • Air filter oil (foam-specific, not engine oil)
  • Nitrile or disposable gloves
  • Replacement air filter if current filter is damaged

How to Clean the Air Filter

  1. Preparation: Place the bike on a stand. Make sure the engine is cool and the ignition is off.
  2. Remove the Seat: Use quick-release bolts or factory seat latches and lift the seat away.
  3. Access & Remove the Air Filter: Unlatch or unscrew the airbox cover retaining fastener(s). Carefully pull the air filter away from the mount. Inspect the airbox for loose dirt; wipe it out with a damp rag if necessary, but be extremely careful to prevent debris from falling into the intake tract.
  4. Inspect the Air Filter: Check the filter for tears, worn foam, or separation at glue seams. If damaged, replace with a new filter.
  5. Wash the Filter: Gently massage a quality foam filter cleaner into the foam. Rinse with warm water from the inside out. Repeat until all dirt and oil are removed. Allow to fully dry – never reinstall a wet filter. Do not use gasoline or harsh solvents.
  6. Apply Filter Oil: Once dry, apply air filter oil evenly, working it in so all foam pores are covered. The filter should feel tacky but not dripping.
  7. Install the Filter: Wipe the airbox sealing surface with a clean rag. Insert the cleaned/oiled filter, ensuring it is properly seated and the edges are forming a continuous seal to the airbox. Reattach cover and seat securely.

Replacing the Air Filter

Replace your air filter if you find rips, severe staining, hard spots, or failing glue seams. These signs mean the foam will not trap dirt effectively, putting your engine in danger. For riders pushing hard on dusty tracks, consider swapping in a new filter mid-ride for best protection.

2024 MC50 Owner-Specific Notes

  • The MC50 uses a compact airbox and filter design, which makes cleanliness especially critical. Dirt can contaminate the intake more quickly than on full-size bikes.
  • Because younger riders may not notice subtle performance drops, adults should inspect the filter after every ride, especially in dusty or muddy conditions.
  • OEM replacement filters and MotoSport.com premium filters are both designed for exact MC50 fitment—do not modify or force incompatible filters into position.
  • Always check airbox cover gaskets and seals during filter service. Replace if worn to prevent leaks.

Recommended Service Interval

Clean or replace your air filter after every major ride, and always after riding in sandy or wet conditions. Neglecting this inexpensive step can lead to costly engine damage on the lightweight, high-revving MC50.

Care Tips Unique to MotoSport Customers

  • Use only premium filter oil formulated for foam motocross filters for best results and longer filter lifespan.
  • Keep a backup oiled filter ready in a sealed bag for fast swaps at the track or trailhead.
  • Dispose of used cleaning fluids responsibly and away from drains or natural water sources.
