If your self-start isn’t working, there’s something wrong with the motorbike battery, spark plug, or stator. Even in some cases, motorbikes show the same problem when there’s something wrong with the motorbike kill switch. If you’re able to start the motorbike with a kick but now with a self-start, there could be something wrong with the wires. 

Let’s look at what it means and what you can do about it. 

While writing this post, I leave no stone unturned so you can know everything about malfunctioning self-start.

Reasons why your motorcycle self start isn’t working: Signs: Details: 
Faulty Battery. Signs like sluggish light, problems in starting a motorbike then battery faulty could be the reason behind it. Faulty batteries won’t even produce single ignition. 
Spark plug.Your motorbike won’t produce a spark. A faulty spark plug won’t produce ignition.

Table Explaining Reasons why your motorcycle self start isn’t working

Faulty Battery: 

A faulty battery can be one of the reasons why your motorbike stops responding.

And unfortunately, many riders do not pay attention to their motorbike battery which will make the situation severe.

If you see signs like sluggish light, problems in starting a motorbike, then battery faulty could be its reason. 

Generally, a motorbike battery goes down when there’s a problem with your stator or an electric charge-producing device, or you’ve installed devices beyond your motorbike battery capacity. 

Spark Plug: 

A bad spark plug is the second reason your motorbike stops responding to the kick and self-start button. 

A spark plug is a device that generates a spark causing your motorbike engine to ignite. 

Spark plug usually stops responding when its ceramic coating cracks, causing the charge to choose the least resistant path. And it prevents the spark plug from generating an electric charge. 

Experts recommend checking the spark plug when igniting the motorbike engine. If you see a small spark, then your spark plug works fine and vice versa. 

Generally, the faulty spark plug is pretty standard when your motorbike is oil or if someone drops your spark plug before installing it in your motorbike. 

Blocked Air Filters: 

Air filter blocks dust particles from going inside your motorbike engine. 

If you do off-road riding a lot, then blocked air filters can be the main reason why your motorbike stops responding. 

If you see signs like a burning smell, not an appropriate air-fuel mixture, or wear of piston and cylinder, then a blocked air filter could be the main reason. 

Experts usually recommend checking your motorbike air filters every 3000 miles. 

Malfunctioned Starter:

Stator malfunctioning isn’t the typical reason, but still, we can’t ignore it. 

The stator is the device that produces an electric charge while you’re riding; the malfunctioned stator would not create an electric charge while riding. 

Although there’s no solid reason why sometimes statorss malfunction, some experts consider installing too many electrical devices on the motorbike as the main reason. 

If you ever experience a whining sound while riding, or motorbike battery stops charging while riding, or you experience sluggish light, then a malfunctioning stator could be the main reason. 

Experts also recommend checking your motorbike’s electrical device every 10,000 miles. 

Dirty Carburetor: 

The carburetor is the motorbike device that helps the fuel and air to mix together for internal combustion. 

Dirt on the carburetor can be caused when you do off-road riding a lot or you don’t clean your internal motorbike parts.

Suppose you ever experience air-fuel mixture problems and your motorbike starts to overheat suddenly. In that case, a dirty carburetor could be the main reason behind it.  

Kill Switch: 

A motorcycle kill switch is a button that helps turn off the motorcycle within a second without touching the key. 

The motorcycle kill switch works by breaking the spark plug circuit, thus turning off the engine instantly. Most motorcycles have kill switches but at different locations. 

I personally had a bad experience when I thought my Harley engine malfunctioned. Later, I found my Harley kill switch was enabled.

And thus, it’s crucial to check if your motorbike switch is on/off, also, don’t forget to see if your motorbike kill switch is malfunctioning or not.

Or, if there’s something wrong with the battery charging plug, it’s advisable to hire a technician to see your motorbike battery. 

Inner Wiring Could be the Reason? 

Inner wiring is a complex place where you can’t figure out any problem easily. 

And this could be the main reason your motorbike self-starter isn’t working. If there’s a loose plug or broken wire, there won’t be a connection between your self-start and the engine. 

To tackle this problem, you could take your motorbike to the technician, where he will check whether your motorbike’s inner wire is connected or not. 

What to Do With a Malfunctioned Stator? 

Undoubtedly a stator is necessary to produce charge while you’re riding, experts recommend checking, and if something is broken, you should consider changing it, you may do it yourself; it’s better to hire a technician.
