Step-by-Step Oil Change Instructions for Your 2015 KX65

Warm Up the Engine

Stabilize the Bike

-
Locate & Remove the Drain Plug
- On the 2015 KX65, the oil drain plug is directly underneath the engine. Use your 14mm wrench or socket to slowly loosen and remove the plug. Avoid hot engine parts and let oil drain into your pan.

Clean and Reinstall Drain Plug

-
Add Fresh Oil
- Remove the rubber oil filler cap on the right side of your engine.
- Using your funnel with a long hose, slowly add exactly 0.5 quarts (500mL) of the recommended 10W-40 trans oil.
Keep the area clean—wipe away dirt so it doesn’t drop inside your engine.
-
Check the Oil Level
- With the bike upright, check the oil sight window located on the right crankcase cover. The oil should appear at the halfway mark in the window.
If it looks low, add small increments; if too high, remove excess—overfilling can pressurize the crankcase.

Dispose of Used Oil Properly
- Take your used oil to a certified recycling center or hazardous waste facility. Never dump oil in drains or on the ground.
