Step-by-Step Instructions

  1. Warm up your bike:– Run the engine for a few minutes so the oil warms up. Warm oil drains more easily and carries more contaminants out of the engine.
  2. Turn off the engine and secure the bike:– Put the bike on a stand to keep it upright and stable, ensuring easy access to the drain and fill points.
  3. Locate the drain bolt:– On the 2019 CRF250R, the oil drain bolt is on the bottom of the engine.
    Call-out:– Do not confuse the engine oil drain bolt with the transmission fluid drain bolt located under the shifter side; ensure you’re draining the engine oil only.
  4. Remove the drain bolt:– Use your 8mm T-handle or socket and let the oil drain completely into your pan. Dispose of used oil in accordance with local environmental regulations.
  5. Remove and replace the oil filter:– Use a 6mm Allen to remove the oil filter cover. Take out the old oil filter and its O-ring. Wipe the mating surfaces clean and install the new oil filter (K&N 116 or equivalent) and a new O-ring. Install the filter with the open side facing out.
  6. Reinstall drain bolt and oil filter cover:– Clean and reinstall the drain bolt, tightening to manufacturer torque specs. Reinstall the oil filter cover, ensuring the O-ring is properly seated.
  7. Add new oil:– Remove the oil fill cap. Using a funnel, add 1.14 US qt (1.08 L) of oil if you changed the filter, or 1.11 US qt (1.05 L) if you did not.
  8. Check oil level:– Replace the fill cap, start the bike, and idle for several minutes. Shut off the engine and allow the oil to settle briefly. Remove the oil check bolt (on the side of the crankcase)—the oil should be level with the opening and may even dribble out – add more or drain some as needed.
  9. Inspect for leaks:– Wipe down all surfaces. Inspect the drain bolt and oil filter cover for leaks once the bike has run and been checked.
  10. Clean up and dispose:– Dispose of the used oil and filter responsibly.

2019 Honda CRF250R Specific Call-Outs

  • Oil Overfill Warning:– Pour in oil until it is level with the oil check bolt opening. The CRF250R’s oil capacity is precise; overfilling may cause excess crankcase pressure or leaks. If oil pours out of the check hole, stop adding more.
  • Correct Oil Filter Sizing:– Use only the specified size (K&N 116 or equivalent) to ensure proper fit and filtration.
  • Break-In/First Service:– If your bike is new or just rebuilt, it’s wise to change the oil and filter after initial break-in (1–3 hours of riding) to remove metallic particles from the engine.
  • Regular Inspection:– Always check the color and consistency of drained oil. Milky or gritty oil signals engine or coolant issues.

Maintenance Tips

  • Change interval:– For aggressive riders or racing, change oil and filter every 3–5 hours of operation. For casual trail riding, every 8–10 hours may suffice.
  • Always use fresh, high-quality oil intended for wet-clutch motorcycles as specified above.
