How to troubleshoot why my Husqvarna Motorcycle engine cannot be cranked (electric starter)?
- C
  Cynthia WalkerAug 17, 2025
  If your Husqvarna Motorcycle engine cannot be cranked using the electric starter, it could be due to several reasons. First, rule out any operating errors by going through the engine starting steps. If the battery is discharged (All TE 250/300), recharge it, check the charging voltage, and check the closed current. A blown main fuse (All TE 250/300) could also be the culprit; remove and reinstall the main fuse. Additionally, the starter relay or the starter motor might be faulty, so check both.

  If your Husqvarna Motorcycle engine overheats, there are several possible causes. Check the cooling system for leakage and ensure the coolant level is correct. If there's too little air stream, switch off the engine when stationary. Dirty radiator fins should be cleaned. If there's foam formation in the cooling system, drain and refill the coolant. Also, inspect the cylinder head and cylinder head gasket for damage. Finally, check for any bent radiator hoses and replace if necessary.

Why does my Husqvarna Motorcycle engine stall or pop into the carburetor?
- M
  Maurice ReedAug 27, 2025
  If your Husqvarna Motorcycle engine stalls or pops into the carburetor, it could be due to a lack of fuel. Turn the fuel tap handle to the ON position and refuel if necessary. The engine might be taking in bad air, so check the intake flange and carburetor for tightness. Also, make sure the connector or ignition coil isn't loose or oxidized; clean the connector and treat it with contact spray.

Why does my Husqvarna TE 125 EU 2015 Motorcycle engine have no idle?
- S
  Steven GrimesAug 30, 2025
  If your Husqvarna Motorcycle engine has no idle, several factors could be the cause. An idling jet blocked can prevent the engine from idling, so check or set the carburetor components. If the adjusting screws on the carburetor are distorted, adjust the idle speed. A defective spark plug can also cause idling issues, so replace the spark plug. Lastly, a defective ignition system can be the culprit, so check the primary and secondary windings of the ignition coil, and check the spark plug connector.
