- Yamaha crush washer (recommended to replace every change)

- Gloves (optional but recommended)
- Bike stand or assistant to keep the bike upright and level
Step-by-Step Oil Change Instructions
-
Warm up the engine: Start the XT250 and let it idle for a few minutes. Warming up the oil helps it drain completely and carries contaminants out with it.
Tip: Never drain oil when the engine is hot enough to burn—just warm. - Stabilize the bike: Place the motorcycle on a steady, level surface. A center stand or secure bike stand is ideal. If using only a side stand, have an assistant help keep the bike upright during oil fill and level checks, as the oil level needs to be checked with the bike vertical and not leaning .
- Remove the skid plate (if installed): You may need to remove the skid plate or engine guard to access the oil drain plug and filter cover.
-
Drain the old oil:
- Place the drain pan under the engine’s oil drain bolt (bottom of the crankcase).
- Use a 17mm socket to remove the drain plug. Allow the oil to fully drain.
- Replace the crush washer on the drain plug if worn or damaged, as a fresh washer ensures a proper seal .
-
Remove the oil filter:
- The XT250 uses a cartridge-style oil filter located behind the right-side case cover.
- Remove the three filter cover bolts (8mm), noting that the top right bolt is longer than the others for proper reinstallation .
- Pull off the cover and remove the old oil filter. Pay attention to the orientation of the filter as you remove it.
- Clean the filter cover and inspect the o-ring for nicks or damage; replace if needed.
-
Install the new oil filter:
- Insert the new filter in the correct orientation.
- Reinstall the filter cover, placing the long bolt in the top right and the short bolt in the top left positions.
- Tighten all three bolts by hand, then to 7.2 ft-lb using your torque wrench .
-
Reinstall the drain plug:
- Thread the drain bolt in by hand to avoid cross-threading.
- Tighten with a torque wrench to 15 ft-lb .
-
Add new oil:
- Remove the oil fill cap on the right side of the engine.
- Use a funnel to pour in 1.37 quarts (1.3 L) of oil if you replaced the filter; 1.27 quarts (1.2 L) if you did not change the filter .
- Start and warm the engine: Briefly run the bike for one or two minutes to circulate the new oil, then stop the engine and wait a minute for the oil to settle.
-
Check the oil level:
- Keep the bike level and upright to read the oil sight glass (located on the right engine side).
- The oil should be between the upper and lower window marks. Add oil in small increments if needed.
- It’s always better to underfill slightly at first, then top-off, than to overfill .
-
Final inspection and cleaning:
- Inspect for leaks around the drain plug and filter area.
- Wipe away excess oil and reinstall the skid plate if equipped.
Yamaha XT250 (2025) Model-Specific Call-outs
- Drain bolt torque: 15 ft-lb is critical–over-torquing can strip the aluminum threads .
- Oil filter cover screws: Insert the long and short screws in their original locations (top right = long, top left = short). Mixing these can cause leaks or side cover warping .
- Sight glass: Always read with the bike standing vertical, not on the side stand, for accurate level .
- Warm-up and double-check: After initial fill and warm-up, the oil filter will absorb some oil, temporarily lowering the level. Double-check and top off after letting the bike idle post-change .
- Oil type: Yamaha recommends Yamalube 10W-40, but fully synthetic 4-stroke motorcycle oils rated for wet clutches are suitable as long as they meet Yamaha specifications. Avoid oils with friction modifiers as these may adversely affect clutch performance .
- Capacity: 1.4 quarts is overfilling–do not exceed 1.37 quarts (with filter) to prevent foam and pressure issues .
