Tools and Supplies Needed

  • 10mm and 12mm socket wrenches (12mm for oil drain bolt)
  • Torque wrench
  • Drain pan
  • New oil filter (Yamaha OEM or high-quality aftermarket)
  • Replacement O-rings or crush washer
  • Funnel
  • Clean rags or paper towels
  • Yamalube 10W-40 or equivalent oil (Check your owner's manual for quantity, typically around 1 quart/950ml for full change with filter)
  • Gloves (optional, but highly recommended for cleanliness and protection)

Step-by-Step Oil Change Instructions

  1. Warm Up the Engine
    • Start the YZ250F and let it idle for a few minutes. This helps the oil to flow more easily and suspend impurities for removal.
      It also ensures an accurate level check when finished.
  2. Turn Off and Secure the Bike
    • Shut off the engine and allow it to sit for 5 minutes to let hot oil drain back into the crankcase.
    • Place the bike upright on a stand so it's completely level.
  3. Access Drain Plug and Oil Filter
    • Remove any skid plate if fitted to access the drain bolt and oil filter cover.
    • Locate the oil drain bolt (bottom of the engine case, right side) and the oil filter cover (right side of engine).
  4. Drain Old Engine Oil
    • Place the drain pan under the bike.
    • Remove the oil filler cap (top right of engine) to break the vacuum and allow oil to drain quickly.
    • Loosen and remove the oil drain bolt with your 12mm socket. Be careful of hot oil.
    • Let oil completely drain out. Inspect the bolt and crush washer for damage; replace washer if necessary for a proper seal on reinstallation.
  5. Change the Oil Filter
    • Remove the oil filter cover using a 10mm wrench.
    • Pull out the old oil filter. Inspect O-ring and replace if worn out.
    • Install the new filter, making sure it is facing the correct direction (look for markings on the filter or compare to the old one's orientation).
    • Reinstall the filter cover and torque bolts evenly to specification.
  6. Clean and Reinstall the Oil Drain Bolt
    • Wipe any debris from the bolt and threads. Replace the crush washer if needed for a leak-free seal.
    • Thread the bolt in by hand to avoid cross-threading, then torque to factory spec (refer to service manual, typically around 20 Nm).
  7. Fill with New Oil
    • Place a funnel in the oil fill hole. Pour in high-quality 10W-40 Yamalube or an equivalent; check your manual for the exact volume. For a 2017 YZ250F with filter change, it's about 1.0 liter (1.06 US qt).
    • Replace the filler cap.
  8. Start and Inspect
    • Start the bike and let it idle for a few minutes, then turn it off.
    • Inspect all areas for leaks, especially around the drain plug and filter cover.
    • Allow to sit for about 2 minutes for oil to settle. Check the oil level via the inspection window (sight glass on the right engine case). Oil should be between the minimum and maximum marks.
    • Add oil if necessary, in small increments.
  9. Dispose of Old Oil and Filter Responsibly
    • Place the old oil and filter in a sealed container. Take them to a motorcycle shop or recycling center that accepts used motor oil and filters.

2017 YZ250F-Specific Call-outs and Tips

  • Tight Space: The oil filter cover and drain bolt are located close to the exhaust and frame rail. A shallow socket and extension may help reach them easier.
  • Crush Washer: Always replace the drain plug crush washer to avoid leaks (very common source of post-service drips).
  • Oil Quantity: Too little or too much oil can harm your engine. Measure carefully and refer to the sight glass for precision.
  • Torque Specs: Overtightening the drain bolt or filter cover can damage the aluminum threads. Use a torque wrench and check your manual for correct settings (usually 20 Nm for drain bolt).
  • Yamalube Oil is recommended for maximum protection, but any high-quality JASO MA oil is acceptable.

Final Checklist

  • All bolts retightened and torqued
  • No leaks at filter or drain bolt
  • Oil level checked with engine warm and settled
  • Old oil and filter disposed of responsibly
