Shop parts for a 2013 Kawasaki KX65 Dirt Bike.
Changing the oil in your 2013 Kawasaki KX65 is an essential part of routine maintenance that protects your engine, ensures smoother shifting, and prolongs the life of your dirt bike. This step-by-step guide provides everything you need to know, including the tools required, detailed instructions tailored for the KX65, and critical model-specific tips.
Tools and Supplies Needed
- 14mm socket or wrench (for drain plug)
- Measuring cup or graduated container (for accurate oil measurement)
- Funnel with a long hose (makes filling easier and cleaner)
- Oil catch pan (for draining old oil)
- Clean rag (for cleaning up any spills)
- Motul 10W40 or similar quality 2-stroke transmission oil
- Half a quart (~500ml) of oil (the KX65 requires approximately this amount)
- Zip tie (optional) (for securing the funnel hose to handlebars)
- Socket wrench (ratchet)
Step-by-Step Instructions
- Warm up your engine (optional): Start the KX65 and let it idle for 2-3 minutes. This step is optional but helps the oil drain more easily, as warm oil flows quicker. Turn off the engine before proceeding.
- Stabilize your bike: Position your bike on a stand to keep it upright and stable on a level surface.
-
Locate and remove the drain plug: Find the 14mm oil drain plug under the engine. Place the oil catch pan underneath, then use the socket or wrench to carefully loosen and remove the drain bolt. Allow the old oil to completely drain into the pan.
- Tip: Be cautious not to overtighten or strip the drain plug when re-installing it later.
- Inspect and clean: Once the oil stops flowing, inspect the drain plug for metal shavings (a little is normal, but excessive pieces can indicate issues). Clean the plug thoroughly and wipe around the drain area with a clean rag.
-
Reinstall the drain plug: Screw the drain bolt back in by hand, then tighten with the socket to snug, but do not overtighten. The aluminum threads can strip easily on this model, so just “snug” is enough.
-
Model-specific tip: The KX65’s oil drain plug is 14mm and should not be torqued aggressively; overtightening risks damage to the threads, which is a common pitfall for KX65 owners.
Reference: "if you want to know the size for your little oil drain plug there, 14 millimeter" and "be careful not to snug this green bolt down too tight or you'll strip the threads"

- Fill with new oil: Set up your funnel and hose. Pour in half a quart (about 500ml) of 10W40 transmission oil. It's best to add the oil slowly, letting it settle to avoid air bubbles. Zip tie the funnel’s hose to the handlebars if needed for hands-free filling. Double-check the measurement for best results.
-
Level check: Start the engine and let it idle briefly, then shut it off. Place the bike perpendicular to the ground and check the site glass (oil level window) on the crankcase. The oil level should be within the indicated marks. If not, add or remove oil as needed until the correct level is shown.
-
Model-specific tip: The KX65 has a small site window, so check the level after the bike runs a minute or two and oil has had time to settle.
Reference: "check your little site window...for how full it is"

Model-specific tip: The KX65 has a small site window, so check the level after the bike runs a minute or two and oil has had time to settle.
- Clean up: Wipe off any oil drips from the engine and frame, and dispose of the used oil responsibly at an auto parts store or recycling center.
- Ride and re-check: After your first short ride post-change, recheck the oil level through the site window. Top up if needed.
Specific Call-outs for 2013 KX65 Owners
- The oil drain plug is 14mm. Don't overtighten; these threads are prone to damage.
- The recommended oil capacity is about half a quart (500ml) of 10W40 transmission/gear oil. Always use oil designed for 2-stroke transmissions, not four-stroke motor oil.
- Always double-check your oil level after running the engine briefly and letting it cool for a minute.
- Change the oil every 3-5 riding hours or more frequently if you ride in muddy or sandy conditions, as contaminants can enter more easily in small-bore race bikes.
