Common Causes of a DRZ400 Big Bore Engine Not Turning

• Faulty Starter Motor: The starter motor is responsible for getting the engine going. If it’s not working, you’ll likely face the issue of the DRZ400 big bore engine not turning.
• Spark Plug Issues: The spark plug helps ignite the fuel in the engine. If it’s dirty or damaged, it can cause problems with starting the engine, leading to the issue of the DRZ400 big bore engine not turning.
