To start your Harley-Davidson Fatboy motorcycle, you can follow these general steps:
Ensure the motorcycle is in neutral: Make sure the motorcycle is in neutral by pulling in the clutch lever (left-hand lever) and using your left foot to shift down until you see the N (neutral) indicator on the instrument panel.
Turn the ignition switch: Insert the key into the ignition switch, which is typically located on the right side of the motorcycle's handlebars. Turn the key clockwise to the "On" position. This will power up the motorcycle's electrical systems.
Prime the fuel system (if necessary): If your Fatboy has a carbureted engine, you may need to prime the fuel system. To do this, locate the fuel petcock (usually located on the left side of the motorcycle's frame) and turn it to the "On" position. If your Fatboy has a fuel-injected engine, there is no need to prime the fuel system.
Engage the kill switch: Ensure that the kill switch, which is typically located on the right handlebar control, is in the "Run" or "On" position. This allows the engine to start.
Activate the choke (if necessary): If your Fatboy has a carbureted engine and it's cold, you may need to engage the choke to enrich the air-fuel mixture. The choke is usually located on the left side of the carburetor. Pull it up or flip it to the "On" position. If your Fatboy has a fuel-injected engine, there is no choke.
Start the engine: With your right hand, press the starter button, which is usually located on the right handlebar control. Keep the starter button pressed until the engine starts. Release the starter button once the engine is running.
Warm up the engine: Allow the engine to warm up for a few minutes before riding. This will help ensure proper lubrication and performance.
These steps are general guidelines, and the specific instructions may vary depending on the model year and configuration of your Harley-Davidson Fatboy. It's always a good idea to consult your owner's manual for detailed instructions and any specific recommendations for starting your particular motorcycle.
