Common motor swaps for the Polaris 400 Scrambler include engines from the Polaris Predator 500 and the Polaris Sportsman 500, as these provide a boost in power and performance. Some enthusiasts also consider swapping in larger engines, such as the Polaris 800 or 850, for even greater performance, although this requires significant modifications to the frame and mounting points. It's essential to ensure compatibility with the ATV's transmission and electronics for a successful swap. Always consult with a professional or experienced mechanic before undertaking such modifications.
