  • Funnel
  • New oil filter
  • 4-stroke engine oil (10W-40 recommended)

Step-by-Step Guide

1. Prepare Your ATV

Ensure your KFX400 is on a level surface and the engine is cool. This prevents burns and ensures accurate oil drainage.

2. Drain the Old Oil

Locate the oil drain plug under the engine. Place the drain pan beneath it. Use a socket wrench to remove the plug and allow the old oil to completely drain into the pan. Once drained, replace the drain plug and tighten it securely.

3. Replace the Oil Filter

Use the oil filter wrench to remove the old oil filter. Before installing the new filter, apply a small amount of new oil to the rubber gasket on the top of the filter. This ensures a proper seal. Install the new filter by hand, tightening it securely.

4. Add New Oil

Remove the oil fill cap and insert a funnel. Pour the recommended amount of new 10W-40 oil into the engine. The KFX400 typically requires about 2.2 quarts. Check the oil level with the dipstick to ensure it's at the correct level.

5. Check for Leaks & Finalize

Start the engine and let it run for a few minutes. Check for any leaks around the oil filter and drain plug. If there are no leaks, turn off the engine and recheck the oil level, adding more if necessary.
