Tools and Materials Needed

  • 8mm socket (for oil filter cover)
  • 10mm socket (for oil strainer)
  • 12mm socket (for drain bolt)
  • Socket wrench
  • Drain pan
  • Oil funnel
  • Yamalube 10W-40 Synthetic (or manufacturer recommended oil)
  • New oil filter (Yamaha OEM preferred)
  • New crush washer/gasket for drain bolt
  • Clean rags or shop wipes
  • Gloves (optional, for cleanliness)
  • Owner’s manual for reference

Pre-Oil Change Preparation

  • Warm up the engine:– Start your YZ250F and let it idle for 2–3 minutes. This loosens contaminants in the oil, making it easier to drain completely.
  • Power off the bike:– Shut off the engine and secure the bike upright on a stand for maximum stability.

Step-by-Step Oil Change Process

  1. Remove the Skid Plate (if equipped)
    Using the appropriate socket, remove the skid plate to access the drain plug.
  2. Drain the Oil
    Position the drain pan under the bike.
    Locate the oil drain bolt on the lower right side of the engine and use a 12mm socket to remove it. Allow the old oil to fully drain.
    Pro MotoSport tip:– Replace the drain bolt’s crush washer to prevent leaks.
  3. Remove and Clean the Oil Strainer
    The YZ250F features an oil strainer for added protection. Remove the strainer using a 10mm socket and inspect/clean it for any debris or sludge. Reinstall when clean and undamaged.
  4. Replace the Oil Filter
    Using the 8mm socket, remove the three bolts securing the oil filter cover (located on the lower right of the engine).
    Carefully remove the oil filter and the cover o-ring. Replace with a new oil filter and a lubricated new o-ring to ensure a leak-free seal.
    Reinstall the cover and torque the bolts evenly to manufacturer specifications.
  5. Reinstall Drain Bolt and Strainer
    After oil has finished draining, reinstall the cleaned oil strainer and the drain bolt with a fresh gasket. Tighten to Yamaha’s recommended torque spec to prevent overtightening (reference your manual).
  6. Add New Oil
    With a clean funnel, pour the recommended amount of Yamalube 10W-40 synthetic (or your chosen high-quality oil) into the filler opening.
    For the 2024 YZ250F, fill to the specified amount as per the owner’s manual.
  7. Check Oil Level
    Reinstall the oil filler cap and start the engine.
    Let the engine idle for 2 minutes, then turn it off and let the bike sit for 1–2 minutes. Check the oil level through the sight glass or dipstick.
    Add oil gradually if needed to reach the correct level (avoid overfilling).
  8. Final Inspection
    Check for leaks around the oil filter cover and drain bolt.
    Wipe any spilled oil from the frame and engine.
  9. Reinstall Skid Plate
    Reattach the skid plate if you removed it.
  10. Oil Disposal
    Properly dispose of used oil and filter at a local recycling facility.

2024 Yamaha YZ250F Specific Call-outs

  • Drain Bolt Torque:– Always follow the 2024 Yamaha YZ250F torque specifications to prevent stripping threads.
  • Oil Filter O-ring:– Lube the new O-ring before installation; a dry O-ring can cause leaks.

Maintenance Frequency Recommendation

  • For aggressive or competition use, change your oil every 4–7 hours of engine time.
