What are the recommended maintenance intervals for the Husqvarna FC 350 2021?

Regular maintenance should be performed every 15 hours of riding. This includes oil changes, air filter cleaning, and checking the chain tension. Consult the owner's manual for detailed intervals and procedures.

How can I troubleshoot starting issues on my Husqvarna FC 350 2021?

Check the battery for charge and connections. Ensure the fuel is fresh and the fuel valve is open. Inspect the spark plug for wear or fouling. If the issue persists, consult a professional technician.

What type of oil should I use for the Husqvarna FC 350 2021 engine?

Use a high-quality, fully synthetic 4-stroke motorcycle oil with a viscosity rating of 10W-50. Always check the owner’s manual for the manufacturer's recommendations.

How do I adjust the suspension on my Husqvarna FC 350 2021 for different terrains?

Adjust the compression and rebound settings on the front fork and rear shock according to the terrain. Softer settings are better for rough terrains, while stiffer settings suit smoother tracks. Refer to the manual for specific adjustment procedures.

What should I do if my Husqvarna FC 350 2021 overheats during a ride?

Stop the motorcycle and let it cool down. Check the coolant level and inspect the radiator for any obstructions. If overheating persists, consult a mechanic to check for potential issues like thermostat or water pump failure.

How can I ensure my Husqvarna FC 350 2021 chain is properly tensioned?
