  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.

  If your KTM Motorcycle engine turns over but doesn't start, several factors could be at play. It could be due to an operating error during the starting procedure. Old fuel in the float chamber can also be a culprit if the motorcycle has been sitting unused for a while. Check if the fuel feed is interrupted, or if the spark plug is oily or wet. Also, the electrode distance of the spark plug may be too wide, or the connector/ignition coil might be loose or oxidized. Clean and dry the spark plug, and adjust the plug gap to 0.60 mm (0.0236 in). Clean the plug-in connection and treat it with contact spray.
