Why does my Husqvarna Motorcycle engine have too little power?
- F

  If your Husqvarna Motorcycle engine has too little power, consider these potential causes. The fuel feed might be interrupted, so check the fuel tank breather and clean the fuel tap; also check the carburetor components. A very dirty air filter can restrict airflow, so clean the air filter and air filter box. Inspect the exhaust system for leaks or deformation and replace the glass fiber yarn filling in the main silencer if needed. Also, a fault in the ignition system could be the reason, so check it. Lastly, inspect the diaphragm and reed valve housing for damage.

Why is my Husqvarna TX 125 Motorcycle engine overheating?
- R
  rjonesSep 12, 2025
  If your Husqvarna Motorcycle engine is overheating, several factors could be responsible. Check for too little coolant in the cooling system, and inspect for leaks and check the coolant level. Ensure there's enough air stream; switch off the engine when stationary. Clean the radiator fins if they're very dirty. If there's foam formation in the cooling system, drain and refill the coolant. Inspect the cylinder head and cylinder head gasket for damage. Finally, replace the radiator hose if it's bent.
