Step-by-Step Oil Change Instructions
-
Warm Up the Engine
- Start your bike and let it idle for about 3-5 minutes. This heats up the oil, allowing it to drain more fully and quickly .
- Turn the bike off and let it rest for a minute so it's not too hot to touch.
-
Remove the Skid Plate
- If your CRF250RX is equipped with a skid plate, remove it using an 8mm socket to access the oil drain plug .
-
Position the Bike
- Stand the bike upright or use a bike stand. This ensures oil will drain evenly. Place the oil pan beneath the engine's drain plug.
-
Remove the Oil Drain Plug
- Locate the drain plug under the engine. Use an 8mm Allen wrench to remove it .
- Allow the old oil to drain completely into your oil pan.
-
Remove the Oil Filter
- Locate the oil filter cover on the right side of the engine.
- Remove the two 8mm bolts securing the oil filter cover .
- Gently pull the cover off and remove the old oil filter. Be careful; some oil will spill.
- Inspect the old oil filter and note any metal shavings–an indicator of unusual engine wear.

Drain Remaining Oil
- Tilt the bike to the right, then left, to ensure all oil is drained from inside the engine .
-
Install the New Oil Filter

- Replace the oil filler cap.
-
Check the Oil Level and Inspect for Leaks
- Start your bike and let it run for a minute. Shut it off and allow the oil to settle.
- Check the oil level using the sight glass or dipstick, adding oil if necessary.

Reinstall the Skid Plate
