Specific Call-outs for the 2016 Yamaha WR250R

  • Oil Change Interval: Yamaha recommends changing the engine oil every 3,000 miles and the oil filter every 6,000 miles. Many owners choose to replace the oil filter at every oil change for optimum engine protection.
  • Oil Capacity: 1.4L (oil and filter change), 1.3L (oil only).
  • Torque Specs: Oil drain bolt: 20 Nm (14 ft-lbs); Oil filter cover bolts: 10 Nm (7 ft-lbs).
  • Sight Glass: Always check the oil level with the bike upright using the sight glass on the right-side engine cover.
  • Don’t lose the O-rings: The oil filter cover uses a small O-ring; inspect and replace if damaged to prevent leakage.

Step-by-Step Oil Change Procedure

  1. Warm up the Engine
    • Start the bike and let it run for a few minutes to warm the oil. Warm oil drains faster and more thoroughly.
    • Turn off the engine.
  2. Stabilize the Motorcycle
    • Place the WR250R on a stand or lift to keep the bike as upright as possible for accurate oil drain and level checking.
  3. Drain the Old Oil
    • Locate the oil drain bolt on the bottom of the engine (left side).
    • Position an oil pan under the bolt.
    • Use a 12mm socket to remove the drain bolt. Be cautious of hot oil.
    • Remove the oil filler cap on the right-side engine cover to speed up draining.
  4. Remove and Replace the Oil Filter
    • Use an 8mm socket to remove the three bolts on the oil filter cover (right side).
    • Carefully pull off the cover—do not lose the small O-ring.
    • Remove the old filter, noting its orientation (the deeper side of the filter faces inward).
    • Inspect the O-ring for wear. Replace if necessary.
    • Install the new filter in the correct orientation.
    • Reattach the oil filter cover, tightening bolts evenly to 10 Nm (7 ft-lbs) to prevent warping.
  5. Install the Drain Bolt
    • Wipe any oil from the drain plug threads and engine case. Install a new crush washer if possible.
    • Reinstall the drain bolt and tighten to 20 Nm (14 ft-lbs) with a torque wrench.
  6. Add New Engine Oil
    • Insert a funnel into the oil filler hole.
    • Pour in 1.4L of quality 10W-40 motorcycle-specific oil (or manufacturer-approved equivalent) if you also changed the filter; use 1.3L for oil only.
    • Replace the filler cap, ensuring the rubber gasket is intact and properly seated.
  7. Start the Engine and Circulate the Oil
    • Start the bike and run for 20–30 seconds to circulate the new oil.
    • Shut off the engine, wait a minute for oil to settle.
  8. Check Oil Level
    • With the bike upright (not on side stand), check the oil sight glass on the right side.
    • Oil should be between the upper and lower lines—not above or below.
    • Top off as necessary but do not overfill.
  9. Finish Up
    • Reinstall the skid plate if removed.
    • Double-check for leaks around the drain bolt and filter area after a brief test ride.
    • Dispose of old oil and filter responsibly.

WR250R-Specific Tips for Oil Change Success

  • Check both the sight glass and for any drips or seepage after your first ride post-change.
  • The filter only installs one way—make sure the deeper side faces the engine; if it doesn't seat easily, flip it around.
  • Never over-tighten bolts—use a torque wrench to protect the WR250R’s aluminum parts from stripping.
  • Replace the O-ring and crush washer regularly to avoid leaks.
