Why is my KTM 85 SX 2022 engine overheating?

  Lynn ChristianJul 29, 2025
  If your KTM Motorcycle engine overheats, several factors could be the cause. It might be due to too little coolant in the cooling system, so check for leaks and the coolant level. Insufficient air stream can also lead to overheating; switch off the engine when standing. Other potential causes include very dirty radiator fins (clean them), foam formation in the cooling system (drain and refill the coolant), a damaged cylinder head or cylinder head gasket (check them), a bent radiator hose (replace it), or an incorrect ignition point due to a loose stator (adjust the ignition).

  If your KTM Motorcycle engine stalls or pops into the carburetor, it could be due to a lack of fuel. Ensure the fuel tap handle is in the ON position and refuel if necessary. Another cause might be the engine taking in bad air; check the intake flange and carburetor for tightness. Also, inspect the connector or ignition coil for looseness or oxidation; clean the connector and treat it with contact spray.
