Step-by-Step Instructions

1. Prepare Your ATV

Ensure your Yamaha YFM200 MOTO-4 is on a level surface and the engine is cool to prevent burns. Engage the parking brake for safety.

3. Replace the Oil Filter

Using the oil filter wrench, remove the old oil filter. Before installing the new filter, apply a small amount of new oil to the rubber gasket on the filter. Screw the new filter into place by hand until it's snug, then tighten it an additional 3/4 turn.
