Tools & Supplies Needed
- 14 mm wrench or socket (for the oil drain plug)
- Measuring cup (to measure the exact oil amount)
- Funnel with a long hose (for easy refilling–recommend tying or zip-tying to handlebars for stability)
- New transmission oil (recommended: 10W-40, non-synthetic or synthetic for dirt bikes)
- Drain pan
- Clean rags or paper towels
- Gloves (optional, for cleanliness)
Step-by-Step Instructions
-
Warm Up the Engine
Run the bike for about 2 minutes. This heats the oil, helping it drain out more thoroughly. After warming, turn off the bike and let it sit upright on a stand. -
Locate and Remove the Drain Plug
Find the oil drain plug underneath the engine (requires a 14 mm wrench or socket). Place a drain pan under the plug, then unscrew the plug and allow the oil to drain completely. Be patient–let gravity do the work.
Pro tip: Always check for any metal shavings on the drain plug magnet; a few are normal, but excess could indicate a problem.
Specific to 2020 KX65: The drain plug for the KX65 is a 14 mm bolt . -
Reinstall the Drain Plug
Once the oil has fully drained, clean and reinsert the 14 mm drain plug. Tighten it securely, but do not overtighten to avoid stripping the threads . -
Add New Oil
Using a funnel with a long hose, refill the engine with new oil. For the KX65, pour in half a quart (473 ml) of 10W-40 transmission oil . Add the oil slowly to avoid overfilling and potential spills.
Specific to 2020 KX65: Oil volume is approximately 0.5 quarts/473 ml. Always refer to your owner’s manual for confirmation in case of an aftermarket mod or difference. -
Check Oil Level
When done, start the bike and let it idle for a minute, then shut it off. Check the oil level using the sight window on the engine case while the bike is upright and on level ground. Oil should be visible near the halfway mark of the sight window–top up if needed. -
Dispose of Used Oil Responsibly
Used oil must always be disposed of at a recycling center or an auto parts store that accepts waste oil. Never pour used oil on the ground or in household drains.
Model-Specific Callouts for the 2020 Kawasaki KX65
- Oil Type: Use 10W-40 transmission oil designed for two-stroke dirt bike engines (do not use standard automotive oil).
- Filling Tip: Use a funnel with a long hose for easy access to the filler. Many riders zip-tie the funnel hose to the handlebars for stability and hands-free filling.
- Drain Plug Caution: Do not overtighten; the aluminum cases can strip easily. Hand tighten and finish with a wrench to snug–for most, this is about 11 foot-pounds (refer to your manual).
- Oil Capacity: 0.5 quarts (473 ml) is the standard refill volume, but always check for proper level in the viewing window.
- Running the Engine: Always recheck oil level after a quick start and idle, since the oil may settle and the initial reading can be slightly off.
Extra Maintenance Tips
- Change the oil after every 5-10 hours of riding or following races, especially if riding in sand, mud, or wet conditions.
- Record each oil change in your maintenance log, noting hours, date, and oil type used.
- Use only high-quality motorcycle-specific transmission oil for best clutch and gear longevity.
- While under your bike, do a quick check of your chain tension, brake pad thickness, and inspect for leaks.
