What causes high oil consumption in my Husqvarna Motorcycle?
- P
  paulhowardAug 17, 2025
  High oil consumption in your Husqvarna Motorcycle can be attributed to several factors. If the engine vent hose is bent, route it without bends or replace it. Check the engine oil level; if it's too high, adjust it. Engine oil that is too thin (low viscosity) can also cause high consumption; change the engine oil and oil filter, and clean the oil screens. Lastly, worn piston and cylinder can contribute to this issue; measure the piston/cylinder mounting clearance.

How to fix a Husqvarna FE 501 when the engine won't crank with the electric starter?
- R
  Robert MasonAug 19, 2025
  If your Husqvarna Motorcycle engine fails to crank using the electric starter, there are several potential causes. First, ensure you are following the correct start procedure. If that's not the issue, check if the battery is discharged and recharge if necessary, verifying the charging voltage, closed current, and alternator stator winding. Also, inspect the main fuse and replace it if blown. Finally, the starter relay or the starter motor itself could be defective and require checking.

What to do if my Husqvarna Motorcycle engine turns over but won't start?
- S
  Scott CurtisAug 22, 2025
  If your Husqvarna Motorcycle engine turns over but doesn't start, consider these possible causes. Ensure you're using the correct starting procedure. Check the fuel hose connection to make sure it's properly connected. Also, examine fuses 1 and 4, replacing them if they're blown. Inspect the spark plug; if it's oily or wet, clean and dry it, or replace it if needed. Make sure the spark plug electrode gap is correctly adjusted to 1.0 mm (0.039 in). Other potential issues include an incorrectly set idle speed (adjust as needed), a defective ignition system, a frayed short-circuit cable in the wiring harness, a defective kill switch or emergency OFF switch, or a defect in the fuel injection system.

Why does my Husqvarna FE 501 Motorcycle engine have low power?
- B
  Brittany MedinaAug 26, 2025
  If your Husqvarna Motorcycle engine has too little power, several factors could be responsible. A heavily contaminated air filter could be the cause; clean the air filter and air filter box. Also, a very dirty fuel filter or fuel screen could be the issue; in this case, change the fuel filter or fuel screen. Inspect the exhaust system for leaks or deformation, and consider replacing the glass fiber yarn filling in the main silencer if it's insufficient. Additionally, check if the valve clearance is too small and adjust it accordingly. The ignition system could also be defective, in which case you should check the ignition coil's secondary winding, the spark plug connector, and the alternator's stator winding.

Why does my Husqvarna FE 501 engine shut off while riding?
- C
  Christie FlynnAug 27, 2025
  If your Husqvarna Motorcycle engine dies during a trip, it could be due to several reasons. The most obvious is a lack of fuel, so refuel. Check fuses 1 and 4 and replace them if blown. A low coolant level in the cooling system can also cause this issue; check for leaks and verify the coolant level. Finally, insufficient airflow can cause the engine to die; switch off the engine when stationary to prevent this.

Why won't my Husqvarna FE 501 Motorcycle engine accelerate properly?
- J
  jason86Aug 30, 2025
  If your Husqvarna Motorcycle engine does not speed up, it could be due to a defect in the fuel injection system. Another potential cause is a defective ignition system. In this case, check the secondary winding of the ignition coil, the spark plug connector, and the stator winding of the alternator.

What does it mean when the malfunction indicator lamp lights up on my Husqvarna FE 501?
- M
  Mrs. Wendy OliverSep 2, 2025
  If the malfunction indicator lamp lights up or flashes on your Husqvarna Motorcycle, it indicates a defect in the fuel injection system. Stop the motorcycle and identify the faulty part using the blink code. Check the cabling for damage and the electrical plug-in connectors for corrosion and damage.

Why is my Husqvarna Motorcycle battery constantly dying?
- A
  Ashley FritzSep 4, 2025
  If your Husqvarna Motorcycle battery keeps discharging, it could be because the alternator is not charging it properly; check the charging voltage and the stator winding of the alternator. Another possibility is an undesired power consumer draining the battery; check the closed current to identify any such consumers.
