What to do if the malfunction indicator lamp lights up on my Husqvarna Motorcycle?
If the malfunction indicator lamp lights up or flashes on your Husqvarna Motorcycle, inspect the cabling for any damage and check the electrical plug-in connections for corrosion and damage. Also, use the Husqvarna Motorcycles diagnostics tool to read out the fault memory.
What to do if my Husqvarna FC 450 Motorcycle engine won't turn over?
If your Husqvarna Motorcycle engine does not turn when you press the electric starter, there are several potential causes: * You may not be following the correct start procedure. * The battery might be discharged, so check the charging voltage, open-circuit current, and the alternator's stator winding. * The main fuse could be blown, requiring a replacement. * There may be a fault with the starter relay or the starter motor itself, which would need to be checked.
Why does my Husqvarna FC 450 Motorcycle have low power?
If your Husqvarna Motorcycle engine has too little power, the possible causes are: * A very dirty air filter, which requires cleaning of the air filter and air filter box. * A very dirty fuel filter, which requires changing the fuel filter. * A defect in the fuel injection system, which requires reading out the fault memory using the Husqvarna Motorcycles diagnostics tool. * A leaky or deformed exhaust system, or too little glass fiber yarn filling in the main silencer, which requires checking the exhaust system for damage and changing the glass fiber yarn filling of the main silencer. * Too little valve clearance, which requires adjusting the valve clearance.
What to do if my Husqvarna Motorcycle engine turns over but won't start?
If your Husqvarna Motorcycle engine turns but doesn't start, make sure the fuel line plug-in connection is properly connected. Other possible causes include a clogged fuel screen in the fuel hose connection (change the fuel screen), an incorrectly set idle speed (adjust the idle speed), a spark plug that's oily or wet (clean and dry it, or replace if needed), a spark plug electrode gap that's too wide (adjust the plug gap to 0.8 mm), a frayed short circuit cable in the wiring harness or a defective kill switch (check the wiring harness and electrical system), or a defect in the fuel injection system (read out the fault memory using the Husqvarna Motorcycles diagnostics tool).
Why is my Husqvarna FC 450 using so much oil?
If your Husqvarna Motorcycle has high oil consumption, check the engine vent hose for bends and correct its routing or replace it if necessary. Also, verify that the engine oil level isn't too high. If the engine oil is too thin, replace the engine oil and oil filter, and clean the oil screen. Lastly, worn piston or cylinder can cause high oil consumption, so measure the piston/cylinder mounting clearance.
Why won't my Husqvarna FC 450 engine speed up?
If your Husqvarna Motorcycle engine does not speed up, there may be a defect in the fuel injection system. To address this, read out the fault memory using the Husqvarna Motorcycles diagnostics tool.
What causes my Husqvarna FC 450 battery to keep discharging?
If your Husqvarna Motorcycle battery keeps discharging, it could be due to the battery not charging, in which case you should check the charging voltage and the stator winding of the alternator. Another possibility is an unwanted power consumer, so check the open-circuit current.
