Tools and Supplies Needed

  • 14mm socket and ratchet (for drain plug)
  • Drain pan
  • Funnel
  • New oil filter (OEM or equivalent – check your owner's manual for part number)
  • 10W-40 motorcycle oil (semi-synthetic or synthetic, approximately 1.1-1.3 quarts)
  • Clean rags or paper towels
  • Gloves (optional but recommended)
  • Torque wrench (for precise reinstallation of the drain bolt)

Steps to Change the Oil

  1. Warm up your engine: Start your KLX300 and let it idle for about 5-10 minutes. This warms the oil, allowing it to drain out more easily and completely.
  2. Prepare your workspace: Place the bike on a flat, stable surface with plenty of room. Consider using a motorcycle stand for more stability. Have your drain pan ready underneath the engine.
  3. Remove the skid plate: If your KLX300 has a skid plate, remove it for easy access to the oil drain bolt.
  4. Drain the oil: Use the 14mm socket to remove the drain bolt located on the bottom of the engine. Let the old oil completely drain into your pan. Inspect the drain plug washer and replace if damaged or excessively worn.
  5. Remove the oil filter: The oil filter is typically located on the right side of the engine. Lay the bike gently on its side if needed for better access. Remove the three bolts holding the filter cover and carefully pull out the filter. Be mindful of any oil that might spill out here as well.
  6. Install the new oil filter: Lightly coat the rubber gasket of your new filter with fresh oil. Insert the filter with the open side facing in towards the engine. Reinstall the filter cover, tightening the bolts evenly and to manufacturer torque specification (consult your manual for the exact torque).
  7. Replace and tighten the drain plug: Once all oil has drained, reinstall the drain plug with a new or good condition washer, tightening it to the recommended torque.
  8. Refill the engine with oil: Remove the oil filler cap on the right-hand side of the engine. Using the funnel, pour in about 1.1-1.3 quarts (refer to your manual for the exact capacity) of 10W-40 four-stroke motorcycle oil. A good indicator is to fill until the level is between the two indents on the oil sight glass while the bike is upright and level.
  9. Check for leaks: Reinstall the filler cap, start the engine, and let it run for a minute. Check for any leaks at the filter and drain plug. Turn off the engine and let it sit for a minute, then re-check the oil level and top off as needed.
  10. Dispose of used oil and filter properly: Take used oil and the old filter to a recycling center or auto parts store that accepts oil waste.
