Why KTM 50 SX 2015 Motorcycle engine turns but won't start?
- M
  Mark MaldonadoJul 26, 2025
  If your KTM Motorcycle engine turns but won't start, there might be several reasons. It could be due to an operating error, old fuel in the float chamber (if the motorcycle was out of use for a long time), or an interrupted fuel feed. The spark plug might be oily or wet, or the electrode distance (plug gap) of the spark plug could be too wide. Another potential cause is a loose or oxidized connector or ignition coil.
