Regularly changing the oil in your 2013 Kawasaki KX250F is critical to maximizing engine life and maintaining top dirt bike performance. This step-by-step guide, proprietary to MotoSport.com, will help you efficiently perform this essential maintenance task. Specific call-outs for the 2013 model are included throughout.

Tools and Supplies Needed

  • Flathead screwdriver
  • Ratchet
  • 14mm socket (drain plug)
  • 8mm socket (oil filter cover bolts)
  • Funnel
  • Drain pan
  • Pliers (optional)
  • New oil filter (specific for KX250F)
  • 1-1.3 quarts of 10W-40 motorcycle engine oil (synthetic or semi-synthetic recommended)
  • Clean rags
  • Contact cleaner (optional for inside the filter housing)
  • Torque wrench

Important Model-Specific Call-Outs

  • Oil Capacity: The 2013 KX250F takes approximately 0.85 to 1.3 quarts of oil; use the sight glass to confirm proper level specific to your bike.
  • Recommended Oil: Kawasaki suggests full synthetic 5W-40 or 10W-40 motorcycle oil for robust protection.
  • Drain Plug Torque: Tighten to 15 foot-pounds (ft-lb) after draining.
  • Oil Filter Cover Bolts: Torque to 9 foot-pounds (ft-lb).
  • Always warm the engine before draining oil—it improves oil flow and ensures a more thorough drain.

Step-By-Step Oil Change Process

  1. Warm Up the Bike:
    • Start your KX250F and let it idle for 3-5 minutes to warm up the oil. Shut off the engine and place the bike securely on a stand.
  2. Remove the Oil Fill Cap:
    • With a flathead screwdriver, loosen and remove the oil fill cap (top right of the clutch cover). This venting helps oil drain smoothly.
  3. Drain the Old Oil:
    • Place a drain pan under the engine.
    • Using a 14mm socket, remove the main oil drain plug at the bottom of the crankcase. Be careful–the oil could be hot. Inspect the crush washer for wear and replace if necessary.
    • Allow the old oil to drain completely. For a more thorough job, tip the bike slightly side-to-side to ensure all oil escapes.
    • If your KX250F has a secondary (smaller) drain plug nearby, remove this as per the owner's manual and drain any remaining oil.
  4. Replace Drain Plug(s):
    • Once drained, replace both drain plugs with their crush washers.
    • Tighten the main plug to 15 ft-lb using a torque wrench.
  5. Change the Oil Filter:
    • Use an 8mm socket to remove the two (sometimes three) bolts from the oil filter cover on the right side of the engine.
    • Carefully remove the cover; a small spring may be behind it, so keep track of its orientation.
    • Pull out the old oil filter with a screwdriver if needed. Clean the oil filter cavity with a contact cleaner (optional) to remove contaminants.
    • Before installing, apply a light film of fresh oil to the rubber gasket/seal of the new filter.
    • Insert the new filter according to orientation (rubber grommet facing forward, spring in place).
    • Reinstall the cover and torque bolts evenly to 9 ft-lb.
  6. Add New Oil:
    • With the bike upright, insert a funnel and pour in 0.85–1.3 quarts of recommended oil. Start slightly below capacity; check the sight glass or dipstick with the bike level.
    • Replace and snug down the oil fill cap.
  7. Start and Circulate:
    • Start your bike and allow it to idle for 3–5 minutes. This helps circulate the new oil throughout the engine.
    • Shut off, wait a few minutes, and then re-check oil level. Top off incrementally if needed; avoid overfilling.
  8. Final Inspection and Cleanup:
    • Check for leaks at the drain plug and filter cover.
    • Wipe away any oil residue, dispose of old oil/filter properly.
    • Ride and monitor initial running for leaks or abnormal noises.

Special Tips for 2013 KX250F Owners

  • Consult your owner's manual for any variation in specs or procedures—factory service intervals and requirements may differ with prior maintenance or hard use.
  • Always double-check the oil level after shut-down and with the bike upright—2013 KX250F has a sight glass for quick visual confirmation.
  • If racing or riding in extremely dusty conditions, shorten oil and filter change intervals for optimal engine protection.
