Tools and Supplies Needed

  • Socket wrench and sockets (12mm/10mm–for drain bolt and oil filter cover)
  • Torque wrench (recommended range: 7.2 ft-lb for oil filter cover screws, 15 ft-lb for drain plug)
  • Oil catch pan
  • Funnel
  • Shop towels
  • New crush washer (for drain bolt–always replace to prevent leaks)
  • New oil filter (OEM Yamaha or quality aftermarket filter)
  • Engine oil: Yamaha-recommended 10W-40 (Yamalube or equivalent, non-energy conserving, motorcycle-specific oil)
  • Gloves (optional but keeps hands clean)

Preparation and Safety

  • Start the engine and let it idle for 2–3 minutes. Warm oil flows better and helps flush impurities.
  • Turn the motorcycle off and let it sit until cool enough to touch, but oil remains warm.
  • Position the XT250 upright and level–Use a center stand or prop the bike vertical (ask a friend for help if needed).

Step-By-Step Oil Change Process for the 2009 Yamaha XT250

  1. Drain the Old Oil
    • Place the oil catch pan underneath the engine’s drain plug (bottom, left side).
    • Using a 12mm socket, remove the drain bolt and crush washer. Let all the oil fully drain.
      NOTE: Replace the crush washer every oil change to ensure a tight seal and prevent leaks.
  2. Remove and Replace the Oil Filter
    • Locate the round oil filter cover on the right side of the engine.
    • Remove the three cover bolts (usually 10mm head) and set them aside.
    • Carefully take off the cover and pull out the oil filter. Watch for the O-ring; gently clean and inspect for nicks or wear–replace if needed.
    • Smear a thin film of fresh oil (or a little waterproof grease) on the O-ring for a better seal and easier future removal.
    • Model-Specific Note: On 2009 XT250, the cover bolts are not all the same length. The longest bolt goes in the top right hole and the shortest in the top left. Keep track to avoid crossing or stripping threads.
      Torque spec: cover bolts to 7.2 ft-lb each
  3. Replace the Drain Bolt and Tighten
    • After oil has finished draining, wipe the area clean.
    • Install a new crush washer on the drain bolt and thread it by hand.
    • Use your torque wrench to tighten to 15 ft-lb–do NOT overtighten.
  4. Fill with New Oil
    • Remove the oil fill cap (right side, above the filter cover). Using a funnel, pour in the fresh oil:
      • With oil filter replaced: Add 1.37 quarts (1.3 liters)
      • Without oil filter replaced: Add 1.27 quarts (1.2 liters)
    • Replace the filler cap securely.
  5. Prime the System and Check Oil Level
    • Start the engine and let it idle for 2–3 minutes, then shut it down and wait a minute for oil to settle.
    • Check the oil level: With the bike upright, look at the sight glass on the right engine cover–oil should be between the upper and lower markings.
    • If low, add small amounts of oil as needed and recheck.
    • Model-Specific Call-out: After replacing the oil filter, the filter will absorb some oil as it primes during the first start-up. Expect the oil level to drop slightly and top up accordingly. Recheck after a short ride.
  6. Inspect for Leaks and Clean Up
    • With the engine off, inspect the drain bolt and oil filter cover for any drips or seepage.
    • Wipe up any spills, dispose of used oil and filters responsibly.

Important Tips and Common Questions

  • Can I use car oil? No–use only motorcycle-specific oils that are wet clutch compatible.
  • Never overfill: Too much oil can cause foaming or increased crankcase pressure, risking engine damage. Fill only to the upper mark on the sight glass, with the bike level.
  • What oil filter? Use OEM Yamaha or a trusted aftermarket filter compatible with the 2009 XT250.
  • Always replace the drain bolt crush washer to avoid leaks.
  • Proper disposal: Take used oil and the filter to a recycling center or auto parts store–never pour down the drain or onto the ground.
  • Keep track of torque specs and bolt lengths–mixing up the oil filter cover bolts is a common beginner mistake on this model.
