Why my Husqvarna FC 350 2022 has high oil consumption?

  Patricia HarrisAug 2, 2025
  If your Husqvarna Motorcycle has high oil consumption, the engine vent hose might be bent; route it without bends or replace it if necessary. The engine oil level might be too high, so check it. The engine oil might be too thin (low viscosity), so change the engine oil and oil filter, and clean the oil screen. Lastly, the piston or cylinder might be worn, so measure the piston/cylinder mounting clearance.

  If the malfunction indicator lamp lights up or flashes on your Husqvarna Motorcycle, it could be due to an error in the electronic fuel injection. Inspect the wiring for any damage and check the electrical plug-in connections for corrosion or damage. Also, read out the fault memory using the Husqvarna Motorcycles diagnostics tool.

  Lauren SmithAug 10, 2025
  If your Husqvarna Motorcycle engine does not turn when you press the start button, it could be due to several reasons. You may not be following the correct start procedure. The 12 V battery might be discharged, requiring you to charge it, check the charging voltage, open-circuit current and the alternator's stator winding. The main fuse could be blown, so replace it. The starter relay or the starter motor could be defective and need to be checked.

  If your Husqvarna Motorcycle engine overheats, it could be due to several reasons. There might be too little coolant in the cooling system, so check for leakage and the coolant level. Insufficient air stream can also cause overheating, so switch off the engine when standing. Dirty radiator fins can restrict cooling, so clean them. Foam formation in the cooling system can also cause overheating, so drain and refill the coolant.

  jamiethompsonAug 19, 2025
  If your Husqvarna Motorcycle engine has too little power, the air filter might be very dirty, requiring cleaning of the air filter and air filter box. The fuel filter could also be very dirty, so replace it. There may be a malfunction in the electronic fuel injection, which requires reading the fault memory using the Husqvarna Motorcycles diagnostics tool. The exhaust system could be leaky or deformed, or have too little glass fiber yarn filling in the main silencer, so check for damage and replace the glass fiber yarn filling. Finally, the valve clearance might be too little, so adjust it.

Why is my Husqvarna FC 350 2022 12 V battery discharged?
- K
  Krystal RamosAug 28, 2025
  If your Husqvarna Motorcycle 12 V battery is discharged, it might not be charging, so check the charging voltage and the stator winding of the alternator. An unwanted electrical power consumer could also be draining the battery, so check the open-circuit current.

  If your Husqvarna Motorcycle engine turns but does not start, it could be due to several reasons. Ensure the quick release coupling is joined. A clogged fuel screen in the quick release coupling can prevent starting, so replace the fuel screen. An incorrectly set idle speed can be the issue, so adjust it. A sooty or wet spark plug can cause starting problems, so clean and dry it, or replace if necessary. If the plug gap of the spark plug is too wide, adjust it to the guideline of 0.8 mm (0.031 in). A frayed short-circuit cable in the wiring harness or a faulty stop button can also be the cause, so check the wiring harness and the electrical system. Lastly, a malfunction in the electronic fuel injection could be the reason, so read out the fault memory using the Husqvarna Motorcycles diagno...
