What are the reasons why a motorcycle won't start after not being ridden for a month?

Motorcycle won't start after not being ridden for a month due to: 1. First determine whether the ignition system can work, check if there is spark output from the spark plug high-voltage wire - spark presence indicates normal operation, absence requires ignition system repair; 2. Check if there is fuel in the carburetor - close the fuel tank switch, loosen the drain screw at the bottom of the carburetor to check for fuel inside, lack of fuel also prevents starting and requires adding appropriate amount; 3. Verify if the carburetor choke operates normally - choke malfunction requires repair. Motorcycles are gasoline-engine driven two or three-wheeled vehicles steered by handlebar-controlled front wheels, being lightweight, agile and fast, widely used for patrol, passenger/cargo transport, and also as sports equipment.
I've encountered a similar situation before. My motorcycle wouldn't start after being parked for a month. A dead battery is the most common cause - when left unused for long periods, the battery naturally discharges. You'll need to check the voltage with a multimeter; if it's below 12 volts, you're in trouble. Another issue could be the fuel - gasoline in the tank may deteriorate or evaporate, forming gum that clogs the fuel system. In this case, cleaning or replacing the fuel should solve it. Then there's the ignition system - spark plugs might get carbon-fouled or damp, causing poor contact. You'll need to remove them to check for rust. Parking conditions also matter greatly, especially in cold winter temperatures when components can freeze. My advice: always fully charge the battery or disconnect the negative terminal before long-term parking, and start the engine periodically for maintenance. Last time it took me half a day to fix - what a hassle! I'll definitely remember to do proper maintenance next time.
I think a month of parking causing failure to start is mostly minor issues, with a dead battery being the main culprit. You can try directly charging it or replacing it. Next could be clogged fuel lines, where old fuel evaporates and blocks the injectors—cleaning the fuel lines and adding fresh gasoline should fix it. Other possibilities include damp spark plugs or oxidized contacts causing a power cut. My habit is to first check if the dashboard lights are on before troubleshooting; if not, prioritize the battery. It's best to keep the bike in a cool, dry place during parking, avoiding direct sunlight. For the battery, investing in a charger/maintainer can prevent recurrence. After each start, ride for a few minutes to let the system circulate. Repairing motorcycles requires patience—troubleshooting step by step isn't complicated.
