Step-by-Step Oil Change Procedure

  • Warm Up the Engine
    • Start the bike and let it idle for about three minutes. This helps the oil flow freely and ensures contaminants are suspended for thorough draining. Make sure not to overheat—it just needs to be warm, not hot.
  • Prepare the Bike
    • Place the RM-Z250 securely on a stand or triangle stand to keep it upright and level for draining.
  • Remove the Oil Drain Bolts
    • Place your oil drain pan beneath the engine.
    • The 2019 RM-Z250 has two drain bolts–make sure to remove both for a complete drain (typically located at the bottom of the engine case)

      .
    • Use the appropriate socket (12mm or 14mm) to remove them. Let the oil drain fully. Inspect the drain bolts and their gaskets; replace any damaged gaskets.
  • Change the Oil Filter
    • Remove the oil filter cover using the 8mm socket or T-handle.
    • Take out the old oil filter and the spring. Carefully remove the old O-ring (use a pick if needed).
    • Lightly oil the gasket on the new filter and the new O-ring for proper sealing.
    • Install the new filter (make sure it seats properly), the spring, and the new O-ring.
    • Reinstall the filter cap and torque the bolts to 11 N·m (8.0 lb-ft)

      .
  • Reinstall the Oil Drain Bolts
    • Clean both drain bolts, reinstall with good or new gaskets, and torque to 14 N·m (10.0 lb-ft)

      .
  • Add New Oil
    • Remove the oil fill cap. Place a funnel in the oil fill hole.
    • Pour in 950 ml of fresh oil if changing the filter (900 ml with no filter change)

      .
    • Replace the fill cap and tighten snugly.
  • Check for Leaks and Confirm Oil Level
    • Start the bike and let it run for a few minutes.
    • Shut off the engine and wait a minute.
    • Check around the drain bolts and filter cover for leaks.
    • Inspect the oil level as per the method described in your owner's manual (typically via sight glass or dipstick, with the bike on a level surface).
    • If needed, add more oil to bring it to specification.
  • Disposal
    • Recycle the old oil and filter at an appropriate recycling center.
