Shop parts for a 1999 Kawasaki KX60 Dirt Bike.

Keeping your 1999 Kawasaki KX60 in peak riding condition means regular maintenance, and one of the most crucial tasks is changing the transmission oil. Doing this at proper intervals ensures smooth shifting, longer component life, and overall reliability on the track or trail. This MotoSport.com-exclusive guide walks you step-by-step through the oil change process, points out every tool you’ll need, and highlights key specifics unique to the KX60.

Tools & Supplies Needed

  • 17mm socket or wrench (for the drain bolt)
  • Drain pan or container to catch old oil
  • Clean rags/paper towels
  • Funnel (small enough to fit the filler hole)
  • Measuring cup (with milliliter or quart markings)
  • New transmission oil: 0.53 quarts / 500 ml (be sure to check your owner’s manual for oil recommendations; high-quality 2-stroke gearbox oil is preferred)
  • Torque wrench (recommended for proper re-tightening)
  • Gloves (optional for cleanliness)

Step-by-Step Oil Change Procedure

  1. Warm Up the Engine
    Run your KX60 for a few minutes to warm up the oil—this helps it flow out more completely. Shut the engine off before beginning the job.
  2. Position the Motorcycle
    Place the bike upright on a stand or securely balanced so it stays perpendicular to the ground for both draining and refilling.
  3. Locate the Drain Plug
    Find the transmission oil drain bolt on the bottom of the right side crankcase. The 17mm drain bolt is easily accessible but may be obscured by dirt or skid plates—clean the area first if needed.
  4. Drain the Old Oil
    Put a drain pan under the bolt. Use a wrench or socket to remove the drain plug and allow the oil to drain completely. This may take several minutes. Wipe any debris off the plug.
  5. Inspect and Reinstall the Drain Plug
    Inspect the drain bolt and its sealing washer for wear or damage. Replace if needed. Thread the plug back in by hand, then tighten with your wrench. Be careful not to overtighten–stripping the threads is a common issue with aluminum cases. Use a torque wrench to factory specs if possible (check your manual for exact torque values for the KX60, but generally 13–18 ft-lbs is standard for similar models).
  6. Refill with Fresh Oil
    Remove the oil filler cap (on the right side of the engine case). Using your measuring cup, pour in the specified amount of oil: 0.53 quarts (500 ml). Use the funnel to minimize spills.
  7. Check Oil Level
    With the bike upright, double-check the oil level. The KX60’s check bolt or fill line is on the right side cover—oil should just reach the bottom edge of the check hole or be visible at the fill line. If no check hole exists, carefully watch the level as you pour in the measured quantity.
  8. Reinstall Filler Cap
    Wipe away any spilled oil and thread the filler cap back in, tightening by hand until snug.
  9. Clean Up & Test
    Remove your drain pan and dispose of the old oil according to local regulations. Start the engine, let it idle for a minute, and ensure there are no leaks from the drain or fill areas.

KX60 Model-Specific Call-Outs

  • Oil Capacity: 0.53 quarts (500 ml). Do not overfill, as excess oil can cause increased clutch drag or transmission resistance.
  • Drain Plug Caution: The KX60 case threads are delicate. Tighten the drain bolt only to the manual’s specification. Over-torquing is a common mistake that leads to expensive repairs if the aluminum threads strip.
  • Oil Type: Use a dedicated 2-stroke gearbox/transmission oil–not standard engine oil–to ensure optimal clutch and gear protection.
  • Oil Level Check: Some KX60 models have a check bolt near the lower clutch cover. Remove briefly after filling; oil should be level with the bottom of the hole. If unsure, rely on precise measuring when pouring in new oil.
  • Routine Interval: Change the oil every 5–10 hours of riding, or more frequently in muddy or wet racing conditions for best engine life.

Additional Tips

  • Always dispose of your used oil at a certified recycling center.
  • Keep a maintenance log to stay on top of regular oil changes, which help prevent premature engine wear and performance loss.
  • If you notice any metallic flakes or unusual debris in your old oil, inspect the clutch and gearbox for wear or service needs.

Regular oil changes are the single best investment you can make in the long-term health and performance of your 1999 Kawasaki KX60. For more Kawasaki tech tips, parts, and supplies, turn to MotoSport.com – your ride, your rules.
