Why my KTM 350 EXC-F EU 2021 Motorcycle engine cannot be cranked (starter motor)?
- K
  Kelly OlsonAug 22, 2025
  If your KTM Motorcycle engine can't be cranked by the starter motor, possible reasons include: * An operating error. In this case, carry out the start procedure. * A discharged 12-V battery. If this is the reason, charge the 12-V battery and check the charging voltage, open-circuit current and the stator winding of the alternator. * A blown main fuse. Replace the main fuse. * A defective starter relay. Check the starter relay. * A defective starter motor. Check the starter motor.

  Valerie GibsonAug 26, 2025
  Several issues can cause a KTM Motorcycle engine to overheat: * Low coolant level in the cooling system. Check the cooling system for leaks and verify the coolant level. * Insufficient airflow. Turn off the engine when stationary. * Very dirty radiator fins. Clean the radiator fins. * Foam formation in the cooling system. To fix this, drain and refill the coolant. * A bent radiator hose. Replace the radiator hose. * A defective thermostat. Check the thermostat. Note that the guideline opening temperature is 70 °C (158 °F). * A defect in the radiator fan system (All Six Days models, XCF?W). Check the radiator fan fuse, fuse 4 and the radiator fan.

Why does my KTM 350 EXC-F EU 2021 Motorcycle have too little power?
- V
  Victoria JohnsonAug 28, 2025
  If your KTM Motorcycle is not delivering enough power, here are some potential causes: * A heavily contaminated air filter. Clean the air filter and air filter box. * A very dirty fuel filter or fuel screen. Replace the fuel filter or fuel screen. * An error in the electronic fuel injection. Read out the fault memory using the KTM diagnostics tool. * A leaky or deformed exhaust system, or too little glass fiber yarn filling in the main silencer. Inspect the exhaust system for damage and replace the glass fiber yarn filling of the main silencer. * Too little valve clearance. Adjust the valve clearance.

Why does my KTM 350 EXC-F EU 2021 Motorcycle have high oil consumption?
- J
  Jasmine DanielsAug 30, 2025
  Several factors can lead to high oil consumption in your KTM Motorcycle: * A bent engine vent hose. Ensure the vent hose is routed without bends, or replace it if necessary. * Engine oil level too high. Check the engine oil level. * Engine oil too thin (low viscosity). Change the engine oil and oil filter, and clean the oil screen. * Worn piston and cylinder. Measure the piston/cylinder mounting clearance.

Why is my KTM Motorcycle 12-V battery discharged?
- V
  Valerie Horton MDSep 2, 2025
  A discharged 12-V battery in your KTM Motorcycle can be due to: * The 12-V battery not being charged by the alternator. Check the charging voltage and the stator winding of the alternator. * An undesired power consumer. Check the open-circuit current.
