  • Ratchet
  • Drain pan
  • Rags/paper towels
  • Fresh oil filter (specific to YZ450F)
  • 1 liter of 10W-40 motorcycle oil (Yamalube or your preferred brand)
  • Gloves (recommended, as oil will be hot)
  • Torque wrench (highly recommended for accurate reassembly)
  • New drain washer (recommended for best seal)

Important Call-Outs for the 2024 Yamaha YZ450F

  • The 2024 YZ450F requires 1 liter of oil for an oil change, including filter replacement.
  • Yamaha recommends using Yamalube 10W-40 or a high-quality 10W-40 engine oil.
  • Change oil every 7.5 hours of riding or after every three races.
  • The drain plug and filter bolts have specific torque specs: oil filter cover bolts to 10 Nm.
  • Do not overfill or install the filter backward; improper installation can cause engine damage.
  • Bike must be upright and on level ground during the procedure. The skid plate may need to be removed for easier access.

Step-by-Step Oil Change Instructions

  1. Warm Up the Engine
    • Start your bike and run it for 3–5 minutes to bring the oil to operating temperature.
    • This helps the oil flow out more easily, carrying sediments with it.
  2. Preparation
    • Turn off the bike and allow it to cool for a minute or two.
    • Position the bike securely on a stand so it sits upright.
    • Gather tools and oil change supplies.
  3. Remove the Skid Plate (if equipped)
    • If your 2024 YZ450F has an aftermarket skid plate, remove it to access the oil drain bolt and filter area.
  4. Unscrew the Oil Filler Cap
    • This allows the oil to flow out more smoothly during draining.
  5. Drain the Engine Oil
    • Place the drain pan under the engine's drain bolt.
    • Using a 12mm socket, carefully remove the drain bolt. Wear gloves, as the oil may still be hot.
    • Allow all oil to drain out completely.
  6. Remove and Replace the Oil Filter
    • Use a 10mm socket to remove the three oil filter cover bolts.
    • Take off the oil filter cover, being cautious of any remaining oil spilling out.
    • Remove the old oil filter. Pay attention to orientation. The filter's hole must face inward toward the engine. Installing backwards can cause engine damage.
    • Install the new oil filter and reinstall the cover. Torque bolts to 10 Nm as specified by Yamaha.
  7. Inspect Oil Strainer (if desired)
    • Experienced owners may wish to inspect or clean the oil strainer at this time, though this is not required at every change.
  8. Replace the Drain Bolt
    • Inspect and replace the washer under the drain bolt if necessary.
    • Hand-tighten, then torque to factory specification for your model (typically 20–30 Nm; consult your owner's manual for precise values).
  9. Add Fresh Oil
    • With a funnel, pour in 1 full liter of 10W-40 oil.
    • Do not overfill. Check oil level via the inspection method specific to your YZ450F (usually sight glass or dipstick).
  10. Check for Leaks and Final Steps
    • Reinstall the oil filler cap.
    • Clean any residual oil from engine and frame.
    • Start the bike and idle for 1 minute. Shut off and re-check oil level, topping off as necessary.
    • Inspect for leaks at the drain plug and filter cover.
    • If removed, reinstall the skid plate.
  11. Dispose of Old Oil Responsibly
    • Take used oil and the old filter to a recycling center or participating MotoSport.com location.

Key Model-Specific Cautions

  • Do not install the oil filter backwards. The open hole must face inward. Failure to do so may require complex engine repairs.
  • Follow the torque specs: Overtightening bolts (especially on the oil filter cover) can strip threads or warp covers.
  • Change the oil after the first few rides on a brand new bike to remove manufacturing debris.
  • Stay on top of maintenance, especially given the YZ450F's performance capabilities and tight service intervals.

Conclusion

By performing regular oil changes using the above steps, your 2024 Yamaha YZ450F will remain in peak condition for the track or trail. Trust MotoSport.com for all your genuine Yamaha parts and supplies.
