Why does my Husqvarna Motorcycle engine overheat?

  Blake DavenportAug 16, 2025
  Your Husqvarna Motorcycle engine may overheat due to several reasons. It could be caused by too little coolant in the cooling system, requiring you to check for leaks and verify the coolant level. Insufficient air stream, necessitating that you switch off the engine when stationary, or very dirty radiator fins, which means you should clean them. Foam formation in the cooling system may also be the problem, suggesting that you drain and refill the coolant. Other potential causes include a damaged cylinder head or cylinder head gasket, advising a check, or a bent radiator hose, which requires replacement.

  If your Husqvarna Motorcycle engine turns but doesn't start, consider these potential causes and solutions. First, ensure you are following the correct start procedure. If the motorcycle has been out of use for a while, old fuel in the float chamber might be the issue, so empty it. Check for any interruptions in the fuel feed, such as a blocked fuel tank breather or fuel tap. Also, a spark plug that's oily or wet should be cleaned, dried, or replaced. Make sure the spark plug electrode distance (plug gap) is correctly adjusted. Inspect the ignition system for any faults and check the kill switch for frayed cables or defects. Clean and treat any loose or oxidized connectors or ignition coils with contact spray. Finally, check for water in the carburetor or blocked jets.

Why won't my Husqvarna Motorcycle engine crank with the electric starter (TX 300)?

  If your Husqvarna TX 300 Motorcycle engine won't crank with the electric starter, there are several possible reasons. It could be due to an operating error during the start procedure. The battery might be discharged, requiring you to recharge it and check the charging voltage, closed current, and alternator. A blown main fuse could also be the cause, so replace it. Additionally, the starter relay or starter motor might be faulty, and each should be checked.
