Why is my Husqvarna FE 350s 2021 Motorcycle engine overheating?
- M
  Marcia RiggsAug 14, 2025
  If your Husqvarna Motorcycle engine overheats, several factors could be the cause. First, check if the coolant level is low in the cooling system and inspect the system for leaks. Ensure there's sufficient airflow, and if stationary, switch off the engine. Clean any dirt from the radiator fins. If there's foam formation, drain and refill the coolant. Inspect for a bent radiator hose and replace if necessary. Check the thermostat, which should open around 70 °C (158 °F). Finally, check fuse 3 and the radiator fan for any defects in the radiator fan system.

How to troubleshoot low engine power on my Husqvarna Motorcycle?
- C
  Chase LongAug 17, 2025
  If your Husqvarna Motorcycle engine has too little power, it could be due to several reasons. The exhaust system might be leaky, deformed, or have insufficient glass fiber yarn filling in the main silencer; check for damage and replace the glass fiber yarn filling. The valve clearance might be too small, so adjust it. The ignition system could be defective; check the secondary winding of the ignition coil, the spark plug connector, and the stator winding of the alternator.

Why does my Husqvarna FE 350s 2021 Motorcycle have high oil consumption?
- G
  Gabriela WhiteAug 20, 2025
  High oil consumption in your Husqvarna Motorcycle can stem from several causes. A bent engine vent hose can be a culprit; ensure it's routed without bends, or replace it if needed. An excessively high engine oil level can also lead to increased consumption, so check and correct the level. Using engine oil that is too thin (low viscosity) can contribute as well; in this case, change the engine oil and oil filter, and clean the oil screen. Lastly, worn piston and cylinder components can cause high oil consumption; measure the piston/cylinder mounting clearance to assess wear.
