How do you start a baja 90cc ATV without a key?

To start a Baja 90cc ATV without a key, locate the ignition wires under the front cover or near the ignition switch. You can bypass the ignition by connecting the power wire (usually red) directly to the starter wire (often a different color, like yellow or green), but be cautious, as this can be dangerous and might damage the electrical system. Make sure the ATV is in neutral and that you have taken appropriate safety measures. If you're unsure or uncomfortable with this process, it's best to consult a professional or the manufacturer's guidelines.
