Why does my Husqvarna Motorcycle has high oil consumption?
- T
  Toni AcevedoAug 15, 2025
  If your Husqvarna Motorcycle exhibits high oil consumption, several factors could be at play. A bent engine vent hose can cause this issue, so ensure the vent hose is routed without bends or replace it if necessary. An engine oil level that is too high can also contribute to high consumption, so check and adjust the engine oil level. Using engine oil that is too thin (low viscosity) can also lead to increased consumption, so change the engine oil and oil filter and clean the oil screens. Lastly, worn piston and cylinder can cause high oil consumption, so measure the piston/cylinder mounting clearance.

Why my Husqvarna FE 450 2018 engine cannot be cranked (electric starter)?
- A
  Anthony JacksonAug 19, 2025
  If your Husqvarna Motorcycle engine cannot be cranked using the electric starter, there are several potential causes. It could be due to an operating error, so make sure to follow the correct start procedure. The battery might be discharged, in which case you should recharge it, check the charging voltage, closed current, and the alternator's stator winding. A blown main fuse could also be the culprit, so replace it. Alternatively, the starter relay or the starter motor itself could be defective, requiring a check.

What to do if malfunction indicator lamp lights up or flashes on Husqvarna FE 450 2018?
- A
  Alexandra SuttonAug 21, 2025
  If the malfunction indicator lamp lights up or flashes on your Husqvarna Motorcycle, it indicates a defect in the fuel injection system. You should stop the motorcycle and identify the faulty part using the blink code. Also, check the cabling for damage and the electrical plug-in connectors for corrosion and damage. It may be necessary to read out the fault memory using the Husqvarna Motorcycles diagnostics tool.

What to do if Husqvarna FE 450 2018 engine turns but does not start?
- S
  Susan PetersenAug 25, 2025
  If your Husqvarna Motorcycle engine turns but does not start, there could be several reasons. You might be making an operating error, so ensure you are following the correct start procedure. Check that the plug-in connection of the fuel hose is connected. A blown fuse 1 or fuse 4 could also be the reason, so replace the fuses. Other potential causes include an incorrectly set idle speed (adjust it), a spark plug that's oily or wet (clean, dry, or replace it), an electrode distance of the spark plug that is too wide (adjust the plug gap to 1.0 mm (0.039 in)). Finally, the ignition system or fuel injection system could be defective, or there could be a short-circuit cable in the wiring harness, so check these systems.

Why does my Husqvarna FE 450 2018 engine overheats?
- J
  jody28Aug 27, 2025
  If your Husqvarna Motorcycle engine overheats, several factors could be responsible. A low coolant level in the cooling system is a common cause, so check for leaks and verify the coolant level. Insufficient airflow can also lead to overheating, so switch off the engine when stationary. 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. Other potential issues include a bent radiator hose (replace it) or a defective thermostat (check it; guideline opening temperature: 70 °C (158 °F)).

What causes Husqvarna FE 450 2018 engine not speeding up?
- D
  deleonrandyAug 30, 2025
  If your Husqvarna Motorcycle engine does not speed up, it could be due to a defect in the fuel injection system, which requires reading out the fault memory using the Husqvarna Motorcycles diagnostics tool. Alternatively, the ignition system may be defective, requiring checks of the secondary winding of the ignition coil, the spark plug connector, and the stator winding of the alternator.

What to do if Husqvarna Motorcycle engine dies during the trip?
- J
  Jeffrey MillerSep 2, 2025
  If your Husqvarna Motorcycle engine dies during the trip, it could be due to a lack of fuel, so refuel. Alternatively, fuse 1 or fuse 4 might be blown, so replace the fuses.

Why Husqvarna FE 450 2018 Motorcycle engine has too little power?
- G
  gail09Sep 5, 2025
  If your Husqvarna Motorcycle engine has too little power, the air filter might be heavily contaminated, so clean the air filter and air filter box. Also, the fuel filter or fuel screen could be very dirty, so replace the fuel filter or fuel screen.

Why is my Husqvarna FE 450 2018 Motorcycle battery discharged?
- J
  John JacksonSep 8, 2025
  If the battery in your Husqvarna Motorcycle is discharged, it could be because the battery is not being charged by the alternator, so check the charging voltage and the stator winding of the alternator. Another possibility is an undesired power consumer, so check the closed current.

Why are combination instrument values deleted (time, stop watch, lap times) on Husqvarna FE 450 2018 Motorcycle?
- S
  Sarah GreenSep 12, 2025
  If the combination instrument values (time, stop watch, lap times) are deleted on your Husqvarna Motorcycle, it is likely that the battery in the combination instrument is discharged, so replace the combination instrument.
