What to do if my KTM Motorcycle engine turns but does not start?

If your KTM Motorcycle engine turns but doesn't start, several factors could be at play. First, ensure the start procedure is correctly followed. Check that the quick release coupling is joined. Blown fuses (Fuse 1 or Fuse 4) can also prevent starting, so replace them. Other potential causes include an incorrectly set idle speed (adjust it), a sooty or wet spark plug (clean, dry, or replace it), or a spark plug gap that's too wide (adjust to 1.0 mm). Also, the ignition system may be defective, so verify it. Finally, check the wiring harness for frayed cables and the electronic fuel injection for errors (using the KTM diagnostics tool).
