Tools & Supplies Needed

  • Torque wrench
  • Drain pan
  • Funnel

  • OEM oil filter
  • Fresh engine oil (Yamalube 10W-40 or recommended)

Preparation

  • Warm up the engine for 2-3 minutes. Warm oil flows better for complete draining. Perform this in a well-ventilated area.
  • Turn off the engine and allow the bike to cool for a minute until it is safe to handle.

Step-by-Step Oil Change Instructions

  1. Remove Skid Plate (if equipped)
    • Unbolt the skid plate using the appropriate socket and set aside for access to the drain plug.
  2. Locate and Remove the Drain Bolt
    • Place your drain pan underneath the engine.
    • Using a 12mm socket, remove the oil drain bolt on the bottom of the crankcase.
    • Allow all old oil to fully drain – standing the bike upright will help to ensure complete drainage.
    • Inspect and, if necessary, replace the crush washer on the drain bolt to prevent future leaks.
  3. Remove and Replace the Oil Filter
    • Locate the oil filter cover on the right side of the engine.
    • Remove the three 10mm bolts securing the cover. Carefully remove the cover and set aside.
    • Remove the old oil filter. Inspect the filter cover O-ring–replace the O-ring if worn or damaged (OEM parts recommended).
    • Install a new OEM oil filter, ensuring correct orientation. Wipe any old oil from surfaces.
    • Reinstall the oil filter cover and hand-tighten bolts. Finish tightening to the correct torque spec from your service manual.
  4. Optional: Clean the Oil Strainer
    • The YZ450F features an oil strainer that can collect debris. It—s accessible by removing an additional side bolt (refer to your service manual for precise location on your 2016 model).
    • Remove the strainer, clean it thoroughly with brake cleaner or light solvent, dry it, and reinstall.
  5. Reinstall the Drain Plug
    • Clean the drain bolt and threads.
    • Install a new crush washer on the drain bolt.
    • Reinstall and torque to OEM spec (check your owner—s manual for exact torque, typically around 17 ft-lb).
  6. Add Fresh Engine Oil
    • Remove the oil filler cap on top of the engine.
    • Using a funnel, pour in the correct amount of fresh oil. The 2016 YZ450F typically takes approximately 1.0 to 1.1 liters when replacing oil and filter, but check your owner—s manual for the exact quantity.
  7. Inspect Oil Level
    • Temporarily reinstall the filler cap.
    • Start the engine and let it idle for 1-2 minutes. Check for leaks at the drain bolt and filter cover.
    • Stop engine, wait about 1 minute, and check the oil level using the inspection window or dipstick (depending on model variation). Add oil if necessary. Do not overfill.
  8. Reinstall Skid Plate and Wrap Up
    • Secure the skid plate if previously removed.
    • Wipe any spilled oil from the engine and frame.
    • Dispose of used oil and filter at an approved recycling facility.

Model-Specific Call-Outs for the 2016 Yamaha YZ450F

  • Oil Filter and Strainer: This model uses both a cartridge oil filter and a mesh strainer. Always inspect/clean the strainer during major oil changes for optimal engine protection.
  • Torque Settings: Always adhere to the service manual—s torque recommendations for the drain plug and oil filter bolts to avoid stripping threads or causing leaks.
  • Correct Oil Quantity: Overfilling can create excess oil pressure, while underfilling leads to inadequate lubrication. Aim for slightly below the maximum mark until you confirm the oil level with the bike on level ground and after a warm-up cycle.
  • Genuine Parts: Use Yamaha OEM filters and recommended Yamalube for best results. Substituting brands or non-OEM components may affect engine performance and longevity.

Final Checklist

  • All drain and filter bolts torqued properly
  • No visible leaks at any gasket or sealing point
  • Oil level confirmed correct after test idle
  • Skid plate reinstalled and secured
  • Tools and waste materials stored or disposed of properly
