How to Change the Oil in a 1993 Kawasaki KX60

Shop parts for a 1993 Kawasaki KX60 Dirt Bike.

Changing the transmission oil in your 1993 Kawasaki KX60 is essential maintenance that helps ensure smooth operation, optimal clutch function, and longevity of your dirt bike. The 1993 KX60 uses a two-stroke engine, so the oil you are changing is for the transmission and clutch, not for engine lubrication. Here’s a comprehensive, proprietary guide for MotoSport.com owners.

Tools & Supplies Needed

  • 10mm or 12mm socket and ratchet (check your specific drain and fill plug size)
  • Oil catch pan
  • Funnel
  • Clean rag
  • Measuring cup (for accurate oil fill)
  • New transmission oil (see notes below)
  • Torque wrench (optional but recommended)
  • Gloves (to keep your hands clean)

Recommended Oil Specifications for 1993 KX60

  • Always use a high-quality two-stroke transmission oil designed for extreme gear and clutch loads. Common choices include brands like Motul, Maxima, or the ones specified for your KX60.
  • Refer to your owner’s manual for precise viscosity and capacity. If you do not have the manual, most riders use 10W-40 or 80W gear oil. Fill capacity is usually in the range of 600-700 ml (about 0.63 – 0.74 US quarts).

Step-by-Step Guide to Changing the Oil

  1. Warm up the bike briefly. Let your KX60 idle for about 2-3 minutes. This helps the oil flow out more completely, carrying away debris. Do not run too long; just enough to warm the oil.
  2. Turn off the bike and set it on a stand. A center stand or triangle stand keeps the bike upright and stable.
  3. Locate the drain bolt. Underneath the right side of the engine case, you’ll see the oil drain bolt. Wipe the area clean before removing to prevent dirt from entering the engine.
  4. Position your oil catch pan. Place it directly below the drain bolt to catch all old oil.
  5. Remove the drain bolt. Use your socket and ratchet to carefully loosen and remove the drain bolt. Let the oil drain completely. Inspect the drain bolt and its washer for excessive metal or debris—some metal filings are normal, but chunks indicate internal issues.
  6. Clean and replace the drain bolt. Wipe any residue off with a clean rag. Inspect the washer or consider replacing it with a new crush washer, then re-install the drain bolt. Tighten snugly but do not overtighten, as the KX60’s cases are aluminum and threads are easy to strip. Consider using a torque wrench and tighten to the manufacturer’s specification (usually around 7-10 ft/lbs).
  7. Remove the oil fill cap. Located on the right side of the engine, near the clutch cover.
  8. Re-fill the transmission oil. Use your funnel and measuring cup to pour in the specified amount of new oil (typically 600-700ml for a KX60). Use the correct oil type and avoid overfilling.
  9. Check oil level (if applicable). Most KX60s have a small inspection bolt or sight hole on the side case (consult your manual for exact location). The oil should just reach the lower edge of this hole. If you’ve filled to specification, you’re likely set, but checking confirms accuracy.
  10. Reinstall the fill cap and clean off any spilled oil from the engine cases.
  11. Start the bike and check for leaks. Let the engine idle for a minute, checking under the engine for any oil seepage from the drain bolt or fill cap.
  12. Dispose of old oil properly. Take the used oil to your local motorcycle shop, auto parts store, or a recycling center. Never dump oil onto the ground or in the trash.

Specific Call-Outs for the 1993 Kawasaki KX60

  • Be gentle with drain bolt threads: The 1993 KX60’s crankcase is soft aluminum, so avoid overtightening the drain bolt to prevent stripping the threads. Use a torque wrench if possible, and check that your washer is in good condition.
  • Exact oil fill: Overfilling can cause leaks or clutch issues. Underfilling risks gearbox damage. Use a measuring cup to pour the correct amount.
  • Check for old gaskets or O-rings: If your fill or drain bolt has a rubber O-ring or gasket, inspect it for cracks and replace if needed to avoid leaks.
  • Change oil regularly: For motocross or frequent riding, change the oil every 5-10 hours of ride time to maximize smooth shifting and prolong clutch life.
  • Transmission oil only: The 1993 KX60, as a two-stroke, uses pre-mix in the fuel for engine lubrication. Only the transmission side gets oil change service.

Common Questions

  • Can I use automotive oil? Only use oil rated for motorcycle wet clutches. Automotive oils may contain friction modifiers harmful to clutches.
  • How do I know if the oil level is correct? If your model has an inspection bolt/sight hole, fill until oil reaches its base while the bike is upright and level.
  • What if I see metal shavings? Fine shimmer is normal. Large chunks require mechanical attention.

MotoSport.com Pro Tip

Always keep a spare drain plug washer and a quart of fresh oil on hand—frequent changes maximize the performance and longevity of your KX60's transmission and clutch. For parts, tools, and premium oils, visit MotoSport.com.
