There could be several reasons why your bike engine is suddenly turning off while riding and requires multiple attempts to start. Here are a few possible explanations:
Fuel-related issues: One common cause could be a problem with the fuel system. It's possible that there is a clogged fuel line, a faulty fuel pump, or a dirty fuel filter, restricting the flow of fuel to the engine. This can lead to fuel starvation and cause the engine to shut off.
Electrical problems: Another potential cause could be electrical issues. Faulty wiring, a loose connection, or a malfunctioning ignition switch may interrupt the electrical supply to the engine, resulting in an engine shutdown. Additionally, a weak battery or a faulty charging system can cause the engine to stall.
Carburetor problems: If your bike is equipped with a carburetor, it may be the culprit. A clogged or improperly adjusted carburetor can cause an imbalance in the air-fuel mixture, leading to engine stalling. Cleaning or adjusting the carburetor may be necessary to resolve this issue.
Ignition system malfunction: The ignition system, including components such as the spark plug, ignition coil, or CDI unit, can contribute to engine shutdowns. If any of these parts are faulty or worn out, it can disrupt the ignition process, resulting in engine stalling.
Overheating: If the engine is overheating, it can lead to sudden shutdowns. Check if the cooling system, including the radiator and cooling fan, is functioning properly. Low coolant levels or a malfunctioning thermostat could cause the engine to overheat.
To determine the exact cause of the problem, it is recommended to have your bike inspected by a qualified mechanic or a service center familiar with Pulsar motorcycles. They will be able to diagnose the issue more accurately by conducting a thorough examination and performing necessary tests.
