Reasons on why scooters won't start

Before you begin to fix your scooter, the first thing you must do is identify the issue. To determine the problem, you need to be familiar with the reasons why a motorcycle doesn’t start. The following are some common reasons why a scooter stops working. 

Electrical issue- this occurs when there’s an issue with the wires running to the starter or ignition. 

Engine issue- this is common when there is a bad spark plug wire. Or, in some cases, a problem in the fuel system.

Fuel system issue- this occurs when there’s a leak or damage in the fuel lines.

Ignition system issue- this happens when there’s a problem with the ignition coil or spark plug wires. 

Starter issue- this happens when there’s a bad fuse or when there’s an issue with the starter motor.

How to Kick Start a Scooter

It is an essential factor you must know if you own a scooter. If you don’t see the safety measures, the manufacturer puts in, kick-starting a bike can be difficult.

Step 1 : The first thing you must do is identify the level. Once you do, you need to fold the footpeg out. 

Step 2 : The next step is you need to take the key and put it into the ignition. Afterward, turn it so that it’s in the start position. 

Step 3 : Make sure that the kill switch is in the on position. If it’s off, the scooter will not start.

Step 4 : Squeeze the breaks and push the kick start peg down. Keep repeating this until the scooter starts, and it will fire up.

Scooter Won't Start With an Electric Starter

This issue occurs in gas-powered scooters when you use an electric starter, and it won’t start. For the bike to start, all its components must work together in harmony.

Some common reasons why this occurs are as follows;


If the engine of the scooter is not starting, but it makes noises, the fuel is not compressing effectively. Issues with the compressor are prevalent. It is because it is the central part of the engine, and it has to go through a lot. 

Unfortunately, you cannot fix issues with the compressor by yourself. It will need professional help and tends to be expensive.

Electrical failure

If your engine refuses to start up entirely, but it sputters, then the chances are high that your battery is dead or low. In this case, a quick fix in the array will help to start the scooter.


When you try to start the scooter, and if the sputtering is low, the issue is with the spark plug. Or shortly said the bike wouldn’t start any spark. Fortunately, spark plugs are cheap. So it will not be an expensive replacement. 

Scooter Won't Start After Sitting

In some cases, scooters refuse to start after it has been sitting for a long time. It happens when you keep the motorcycle sitting in the winter. Or, in some other cases, the scooter won’t start after sitting overnight, or the bike won’t start when cold. Some reasons why this happens are as follows;

When you leave a motorcycle unused for 7hrs the temperature of the engine oil decreases. It causes the fuel to become thicker and sediments to the bottom. It is because, at night, the temperature is low. 

It is most common in two-wheelers as the battery power is not as durable as cars. Kick-starting the scooter will make the starting procedure easier. You can follow the following steps to deal with such a situation. 

Step 1 : Give 10 to 12 soft kicks while the ignition is off. Make sure that the kicker goes down entirely. When you do this, it leads to better decompression, and the density of the engine oil will loosen. It guarantees adequate circulation of oil.

Step 2 : This time make sure that the ignition is on. Afterward, give a strong kick with mild acceleration. In the first or second, the scooter will start.

Scooter Starts But Won't Stay Running

Some of the reasons why this occurs are;

The engine bay has loose cables- tug on each wire to make sure that none of them are free. If you find a loose cable reconnect it. Once you restart the scooter, it should work fine. 

Intake leaks- a quick fix to this issue is by rubbing heat resistant silicone paste. It will avoid further damage to the scooter and cover up the damaged area. 

Changes needed in the Intake Valve- this occurs when the valves are either too loose or tight. It causes issues. 

Clogged Carburetors- even if a tiny piece of dirt gets in the carburetor, it can cause issues. Unfortunately, this type of problem can be tricky to fix by yourself. But if you want to fix it reasonably, you need to dismantle and clean the carburetor.

Scooter Will Kick Start but Not Electric Start

You will face this issue when there’s an issue with the valves. In this case, check the valve clearances. But there’s also a chance there is an issue with the battery. To make sure, get a load test done. 

Also, make sure to clean all the ends thoroughly. Resistance occurs when there’s a dirty connection. Due to this, the charging system and battery begin to work harder. Or, if the battery is weak, it will not be fast enough for the scooter to fire up. It is true, especially in cold weather.

50cc Scooter Won't Start Spark and Fuel

If the scooter has spark at the plug gap, then the following are some reasons why it won’t start:

» No compression

» No fuel-air mixture

There are many little spaces that a carburetor has that you might miss when it gets stopped up with junk. Take your time and carefully clean small orifice. 

You can also do a check-up to find out the issue by spraying a small amount of starting fluid. Spray this into the intake while cranking it. If you have a spark, then it must fire for a few seconds.

Moped won't Start Just Click

When you try to start your moped, and there’s a clicking noise, there are three reasons why this may happen. 

Dead battery- to consider a battery ‘charged,’ it must have 12.2volts. If it’s lower than 12.2 your scooter will not start, you will only hear a clicking sound. So if you want to get your motorcycle started, then you must recharge the battery. 

Bad starter- the magnetization receives power from the battery. And the starter is what directs the function of each part. If the magnet that turns the flywheel by polarizing the gear isn’t magnetizing correctly, the speed won’t turn the wheel. It makes the clicking sound.

Seized engine- the engine takes due to reasons such as piston rings, pistons, and rod bearings. These become hot and start to weld together.

Scooter Won't Start After Running Out Of Gas

If your scooter runs out of gas and once you refill it does not start, do the following:

» Make sure that you refill the tank with fuel

» Turn the ignition to the ON position 

» Turn the engine run/stop button to the run position

» Until it stops let the fuel pump run

» Turn the engine run/stop button to the stop position

» Wait for ten seconds. It will reset the engine control module

» Repeat the above steps for 4 or 5 times

Scooter Turns Over But Won't Start

If your scooter turns over but does not start, check the spark. Afterward, see if gas is getting to the engine. If there’s no spark, the problem is with the ignition. You will have to replace the electronic ignition module. Or it can even be due to a faulty coil or a loose wire.

If there’s a spark, check the gas. If there is gas, then you must check the fuel valve. To test this, you must disconnect the hose from the carburetor. Once you crank the engine fuel should run out.  If this does not happen, the issue is with the fuel valve.


Shortly said, if you know how a scooter works, fixing it won’t be a task. Once you have an understanding of each part of a motorcycle, you can adjust most of the issues. If you want to avoid any unnecessary spending, make sure to read the manual. 

Once you maintain the scooter well, you will realize how the number of issues and breakdowns lessen. So, always make sure to keep your bike by cleaning it and using it in the right way. If you do this, you can save a lot of money that you would otherwise be spending on repairs.
