Tools and Supplies Needed
- 14mm socket and ratchet
- Oil drain pan
- Funnel
- Measuring cup (marked for 700mL)
- Clean rags/shop towels
- Replacement crush washer (optional/recommended)
- Transmission oil (10W-40 or manufacturer-approved gear oil)
- Gloves (to keep your hands clean)
Oil Change Interval
- The KX85 manual recommends replacing the transmission oil every three to five hours of use depending on riding conditions and intensity. Regular maintenance preserves clutch and gear longevity and ensures smoother shifting.
Step-by-Step Oil Change Process
- Warm up the engine
- Start the bike and let it idle for about a minute. Warming the oil helps it drain faster and more thoroughly.
- Stabilize the bike
- Place your KX85 upright on a stand or level surface to prevent spills.
- Locate the drain plug
- The oil drain plug is underneath the right side of the engine case. Use a 14mm socket to loosen the plug.
- Drain the old oil
- Set the oil pan beneath the plug. Remove the plug and allow all the oil to drain out completely. Wait several minutes for the oil to finish draining.
- Inspect the used oil for any unusual metal fragments or cloudiness, which could indicate internal engine wear.
- Inspect and clean the drain plug
- Wipe off any metal shavings from the magnetic drain plug. Replace the crush washer if worn.
- Clean around the drain area to prevent dirt from contaminating the new oil.
- Reinstall the drain plug
- Screw in the drain plug by hand, then gently tighten with the socket wrench. Do not overtighten—these aluminum threads strip easily. Tighten snug, but not excessively – typically 7.2 lb-ft (10 Nm) is sufficient for the KX85. Double-check for leaks before proceeding.
- Measure and add new oil
- The 2010 KX85 oil capacity is 700 milliliters (mL). Use a measuring cup to ensure accuracy.
- Pour new oil into the fill plug opening (on the right side of the engine case) using a funnel for a clean fill.
- Only use the recommended oil type—typically 10W-40 motorcycle-specific transmission oil.
- Replace the fill cap
- Reinstall the oil fill cap securely by hand. Wipe away excess oil from the engine case.
- Check the oil level
- Stand the bike perpendicular to the ground (off the stand). Look into the oil check window or reference the notch near the fill hole; the oil level should reach this reference.
- Add or remove oil as necessary for an accurate level.
- Clean up and perform a final check
- Start the engine and let it idle for 30 seconds. Check for leaks at the drain plug and fill cap. Shut off the engine and re-check the oil level, topping off if needed.
- Dispose of the old oil properly according to local regulations.
KX85-Specific Tips & Notes
- Be careful not to overtighten the aluminum drain bolt to avoid stripping threads.
- This process is the same for all modern KX85 models. Always double-check the correct oil quantity for your year and model, but 700 mL is standard for the 2010 KX85.
- The KX85 uses transmission/gear oil, not 4-stroke engine oil; engine lubrication is managed by the pre-mixed gas and oil.
- Check your owner's manual for specific torque specs and oil recommendations for your model and region.
Why Regular Oil Changes Matter
- Regular oil changes protect your clutch and transmission gears from excessive wear and ensure smooth shifting on the track or trail.
- Neglecting this simple service can lead to costly repairs down the line.
