Shop parts for a 2004 Kawasaki KX60 Dirt Bike.

This proprietary MotoSport.com guide walks you through the step-by-step process to change the transmission oil in a 2004 Kawasaki KX60–a crucial task to maintain smooth shifting and long engine life. Below you'll find the specific tools required, detailed procedure, oil specifications, and key owner call-outs unique to this model.

Tools & Supplies Needed

  • 10W-40 motorcycle oil (API certified, non-energy conserving formula recommended for two-stroke transmissions)
  • Measuring cup (to ensure accurate oil volume)
  • 14mm wrench or T-handle (for drain bolt)
  • Oil catch pan
  • Clean rag or paper towels
  • High temperature silicone (optional, if gasket is worn)
  • Replacement drain bolt washer/gasket (highly recommended; prevents leaks)
  • Funnel (aids in tidy filling)
  • Service manual (for torque specs and reference)

Step-by-Step Oil Change Instructions

  1. Warm Up the Engine
    • Run the engine for 2–3 minutes to ensure the oil flows out smoothly and carries away contaminants.
    • Shut off the engine and place the bike on a level stand.
  2. Remove the Drain Bolt
    • Position your oil catch pan beneath the transmission drain bolt (usually located on the bottom of the right engine case).
    • Use your 14mm wrench or T-handle to slowly remove the drain bolt. Be careful not to drop the bolt into the oil pan.
    • Let the old oil fully drain out–this may take several minutes.
  3. Inspect & Prep the Drain Bolt
    • Check the copper or aluminum washer/gasket on the drain bolt. If it’s worn, cracked, or flattened, replace it to prevent leaks.
    • If reusing the gasket, ensure it’s in good condition and clean off any old oil or debris.
    • Some riders apply a thin layer of high-temp silicone to assist sealing if the gasket is questionable.
  4. Reinstall the Drain Bolt
    • Thread the drain bolt in by hand to avoid cross-threading.
    • Tighten snugly, but do not over-tighten–the KX gearbox case threads can strip easily. Reference the manual for the correct torque spec (usually about 10–12 ft-lbs). If no torque wrench is available, “firm hand tight” with a short wrench is safe.
  5. Measure and Fill Fresh Oil
    • Reference your KX60’s manual; most models require about 650ml (22 oz) of oil. Always verify your exact spec.
    • Use your measuring cup to portion the correct volume.
    • Remove the fill cap (located atop the right-side engine cover) and pour oil in using a funnel to avoid spills.
    • Replace the fill cap once finished.
  6. Check the Oil Level
    • Set the bike upright on level ground (not on side stand).
    • With the correct amount of oil, the level should be at the bottom thread of the fill opening or as indicated by a sight window/notch if present.
    • Add a small amount if not visible–do not overfill.
  7. Final Check and Clean Up
    • Wipe up any drips. Inspect for leaks around the drain bolt as the bike sits.
    • Properly dispose of used oil at a recycling center.

KX60-Specific Tips and Call-Outs

  • Drain bolt threads on older small-bore Kawasakis are easily stripped. Always start by hand, and never overtighten.
  • If your bike has a plastic fill cap, check for cracks and ensure the O-ring is present and pliable—replace if damaged.
  • The KX60 does not have an oil filter; the oil serves only the gearbox and clutch. Change oil more frequently if riding hard or in dirty/wet conditions.
  • Be cautious: The KX60 shares a similar oil change method to the KX65, KX85, and other Kawasaki two-strokes from the 2000s, but oil volume may differ. Always use your specific model’s data.
  • When in doubt, consult your Kawasaki service manual for the exact fill specification and torque values for the 2004 KX60.

Why Fresh Oil Matters

  • Fresher oil provides optimal clutch feel, smooth shifting, and extends the life of internal components.
  • Old or dirty oil causes clutch slippage, poor shifting, and additional engine wear.
  • Make it a habit to change your KX60’s oil after every few races or every 5–10 hours of riding, whichever comes first.
