  If your KTM Motorcycle engine turns over but doesn't start, there could be several reasons: * **Operating error:** Ensure you are following the correct engine starting procedure. * **Old fuel:** If the motorcycle has been stored for a long time, the fuel in the float chamber may be stale. In this case, empty the carburetor float chamber. * **Fuel feed interrupted:** Check the fuel tank breather, clean the fuel tap, and inspect/adjust the carburetor components. * **Spark plug issues:** If the spark plug is oily or wet, clean and dry it, or replace it if necessary. Also, check the spark plug electrode gap and adjust it to 0.60 mm (0.0236 in) if it's too wide.

  If your KTM Motorcycle engine turns but refuses to start, consider these potential causes and solutions: * **Operating error:** Review the correct engine starting procedure. * **Old fuel:** If the motorcycle has been sitting, old fuel in the float chamber might be the issue. Empty the carburetor float chamber. * **Fuel feed interrupted:** Make sure fuel is flowing correctly by checking the fuel tank breather, cleaning the fuel tap, and inspecting/adjusting the carburetor components. * **Spark plug condition:** A spark plug that's oily or wet can prevent starting. Clean and dry the spark plug, or replace it if needed. * **Incorrect spark plug gap:** An improperly gapped spark plug can also be the culprit. Adjust the plug gap to the recommended 0.60 mm (0.0236 in).
