The video shows a close-up of a motorcycle engine. A person's hand is seen holding a small plastic cup, which is being used to pour a clear liquid into the engine. The liquid is being poured into a specific area of the engine, which is not clearly visible. The person's hand is steady, and the liquid is being poured carefully to avoid spilling. The engine is metallic and has a shiny surface, reflecting the light in the room. The background is blurred, but it appears to be a garage or workshop setting.
