Many times I have to go for my work in the early mornings and every time I have to face the same common problem. Every time in the morning, my bike doesn’t start or it takes some time to start.

This problem is not limited to only mornings, but I face this problem in the winter season, too. Like me, a lot of people face this same problem, and often you might have the question in your mind why my bike is not starting in the morning. 

That’s why I decided to write this article to inform you about the actual reason behind this problem and to give you a solution to this annoying problem.

Why My Bike is not Starting in the Morning

The reason for this problem is a cold engine. A motorcycle or bike doesn’t start in the morning properly when it’s temperature is lower. Due to a lower temperature, engine oil can not flow freely, the battery can’t produce enough electrical current, and eventually, the engine can not produce sufficient energy to start the bike.

In the mornings, generally, atmospheric temperature is very low. This lower atmospheric temperature is the reason behind this problem. Because it is difficult for any engine to work properly in cold conditions. Lower atmospheric temperature affects in many ways on the performance of the bike engine.

Effect of Cold Atmosphere on the Battery of the Bike

So, why does the motorcycle hard to start in the cold atmosphere of the morning? The Low-performance of the battery due to the cold atmosphere in the morning is one of the main reason behind this problem.

Battery plays a very important role as it helps for proper combustion of fuel. The battery creates the electrical current and that electrical current helps for the combustion of the air-fuel mixture or fuel in the engine. But, we often forget that battery of our bike or motorcycle works on the chemistry.

The electrical current produced in the battery is the result of the chemical reaction in the battery. And the speed of the chemical reactions depends on the atmosphere temperature. If the atmosphere temperature is high then the speed of the chemical reaction will be high. If the atmospheric temperature is low then the speed of the chemical reaction will be slow. That why in the mornings or early winter, the battery struggles to create the required electrical current. Less electrical current can not provide the required power to the motorcycle and then it results in the starting problem of your bike.

Effect of Cold atmosphere on Engine oil

In the morning or in the winter season, atmospheric temperature is very low. Due to this lower temperature, engine oil becomes thicker or you can say the viscosity of the engine oil increases. When the viscosity of the engine oil increases, the engine oil becomes thicker and it can’t run freely in the motorcycle.

In other words, you can say that thicker engine oil takes more power as compared to thinner oil to run freely inside the motorcycle. So, in a cold atmosphere, thicker engine oil puts an additional burden on the low performing batteries that can result in the shortage of energy for the combustion of the fuel.

Formation of Moisture in the Fuel Lines

The third reason is the formation of the moisture in the fuel lines, due to low atmosphere temperature. Sometimes, in cold conditions, moisture is formed inside the fuel lines. If the moisture is formed inside the fuel lines and your bike has thin fuel lines then fuel could be blocked in the fuel lines due to moisture. Due to this, your engine won’t get enough fuel to start the bike.

Lean Air-Fuel Mixture

You may know that the air-fuel ratio plays a very important role in the efficiency, maintenance, and performance of the engine. In the morning or in the winter session, the air is denser and more cooler.

So, when such a denser air is taken into the motorcycle then it results in the formation of the leaner mixture. So, the combination of the low temperature and the lean mixture makes it difficult for the engine to produce the necessary power to start the bike in the morning.

When we say that air to fuel ratio is high that means it contains a high amount of air as compared to the fuel and such mixture is called a leaner mixture. The leaner mixture provides more power and more efficiency. When we say that air to fuel ratio is low that means fuel is present in high amount than air and such mixture is called a richer mixture. The richer mixture doesn’t provide proper combustion and it provides low efficiency.

How to Solve Bike Starting Problem in the Morning

Until now, we discussed the problem. Now, we will talk about the solution. I have given some ways that have worked for me to get rid of this problem. Now, let’s talk about how to solve bike starting problem in morning.

Provide choke

As you know, in the morning, air to fuel ratio is lean due to the cold atmosphere. That’s why it is difficult to start the engine. But, we can get rid of this problem by converting this leaner mixture into the richer mixture with the help of choke.

When we provide choke, it helps to supply additional fuel in the carburetor of the motorcycle. As the amount of fuel increases, the air to fuel ratio becomes rich and the engine gets additional power.

If your bike gets started after providing the choke, then you should keep the choke on until the engine is sufficiently heated. After the engine gets heated sufficiently, you close the choke.

Turn off unnecessary Electrical equipment

In the cold condition, your battery can not produce sufficient electrical current. Due to less electrical current, the required heat is not generated and that’s why the combustion process can not be started in the engine.

But, at the same time, the electrical current produced by your battery is consumed by different electrical instruments like radio, heater, and headlights. You should turn off these electrical equipments so that the electrical current produced by the battery would only be supplied to the engine.

Use Low-Grade Engine Oil

Engine oil is a very important part of the bike. It helps to reduce the friction between different parts. It helps to cool the engine and remove the unwanted impurities inside the engine.

There are two types of engine oil that are low-grade engine oil and high-grade engine oil. High-grade engine oils come with high viscosity and it is recommended to use these high-grade engine oils if you live in the warmer place.

Whereas low-grade engine oils come with low viscosity and it is recommended to use this low-grade engine oils if you live in the cold atmosphere. Due to their low viscosity, low-grade engine oils can run freely even in the cold conditions. In this way, by using low-grade engine oil, you will help your bike engine to start quickly even in cold conditions.

Use insulation material to cover bike

If you need to go to your work daily in the morning and you are facing the same cold start problem every morning then you should consider using insulation material for your bike.

The main reason for the cold start problem is the cold atmosphere. Due to the cold atmosphere, your bike engine loses its heat in the night time, and then the engine takes some time to gain the required heat before starting in the morning.

That’s why I am suggesting you cover your bike with insulating material so that it will significantly reduce the rate of heat loss of the engine in the night time. You should spend some money to buy insulation material if you are facing the cold start problem on a daily basis.

Conclusion

The cold engine is the main reason why your bike is not starting in the morning. The cold atmosphere in the morning or winter session affects negatively the performance of the engine and battery. Due to low performance, the engine can not produce sufficient energy to start the bike and that’s why it is difficult to start the bike in the morning. But, we can get rid of this problem by taking some precautions.
