How to fix a KTM 250 EXC TPI 2019 Motorcycle when the engine cannot be cranked with the electric starter?
- S
  Shelby ChapmanAug 3, 2025
  If your KTM Motorcycle engine fails to crank with the electric starter, several issues could be responsible. Begin by ensuring you are following the correct start procedure. A discharged battery is a common cause; recharge it and check the charging voltage, closed current, and alternator stator winding. Inspect the main fuse and replace it if it's blown. Also, the starter relay or the starter motor itself might be faulty and require inspection.

Why does my KTM Motorcycle engine have no idle?
- J
  Jasmine RobertsAug 14, 2025
  If your KTM Motorcycle engine won't idle, consider these possible causes: a defective spark plug (replace it), faulty ignition (check the ignition coil, spark plug connector, and alternator stator winding), or an incorrectly set idle speed (adjust the idle speed).
