Why is my Husqvarna Motorcycle engine overheating?

  Ronald ValdezAug 6, 2025
  If your Husqvarna Motorcycle engine overheats, several factors could be the cause. It could be due to too little coolant in the cooling system, which means you should check the cooling system for leakage. Insufficient air stream can also cause overheating, so switch off the engine when stationary. 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), or a bent radiator hose (replace it).

  If your Husqvarna Motorcycle engine stalls or pops into the carburetor, it could be due to several reasons. One possibility is a lack of fuel, so ensure the fuel tap is in the ON position and refuel if necessary. Another cause might be the engine taking in bad air; in this case, check the intake flange and carburetor for tightness. Also, the connector or ignition coil might be loose or oxidized, so clean the connector and treat it with contact spray.
