What to do if my KTM 450 SX-F EU Motorcycle engine turns but does not start?
- J
  Jessica MccoyAug 17, 2025
  If your KTM Motorcycle engine turns over but fails to start, several factors could be at play. First, check the fuel hose connection to ensure it's properly joined. Next, inspect the spark plug; if it's oily or wet, clean and dry it, or replace it if needed. Lastly, verify the spark plug's electrode distance, adjusting it to the recommended gap of 0.9 mm (0.035 in) if it's too wide.
