Complete guide to changing the spark plug of your bike  04th August 2022

If you are a biker, you know the importance of maintaining your bike in top-quality condition. Some people learn ways to keep their bikes on their own, while others depend heavily on mechanics and service stations to maintain their vehicles properly. In this article, we will understand the functions of one of the most vital components of a bike, the spark plug, and how to maintain and change it.

What is a spark plug?
A device that delivers electric current to the combustion system via the ignition point is known as a spark plug. A spark plug ignites and fuels the vehicle using an electric spark while maintaining the engine pressure.

What key dimensions do you need to look for in a spark plug?

1. Diameter:
The right diameter is imperative for the proper functioning of the spark plug. The wrong diameter can affect the internal components and damage the bike.

2. Reach:
The spark plug's optimal range or reach determines its ignition capacity. If the length of the spark plug is too short, it will fail the ignition. And if it is too long, it might ignite pre-emptively or get jammed and hit the valve inside.

3. Range:
The range of the spark plug is calculated by the distance from the insulator's tip to the ceiling ring. A longer distance will heat the plug and cause pre-ignition, while a shorter range results in a colder plug resulting in easy wear and tear.

4. Gap:
The distance between the centre and the grounded electrode is known as the spark plug gap. The bigger the size of the gap, the bigger the spark produced.

What are the indicators of a damaged spark plug?

1. When you stop the bike, and the engine starts sputtering or idling, it indicates a failed spark plug.

2. If you have trouble starting your bike engine, it could indicate trouble with ignition and the spark plug.

3. If you notice corrosion in various parts around the spark plug, then it is high time to change your spark plug.

4. You might have a faulty spark plug if you notice a poor fuel economy.

Various other factors are indicators of a faulty spark plug. If you notice any problem while riding your bike, it is best to take your vehicle to a mechanic and inspect it as soon as possible.

How to change a spark plug at home?

Although it is advisable to make any changes to your bike under the supervision of a trained mechanic, if you want to change your spark plug, the following list will help you with that.

1. The first thing that you need to do when changing a spark plug is to pull the cap and remove the wire. Remember to do it gently, as a sudden tug or pull can damage the connection and prevent the ignition from happening.

2. Attach the ratchet to the plug and make sure that the plug is fitting properly inside the socket. Using the ratchet, turn the spark plug till it is loose, and then carefully remove it.

3. Inspect the plug for oil and soot deposits or other damage. If the spark plug is greasy and dirty, it is high time to change it with a new one.

4. Before fixing a new spark plug, it is better to check for the range, diameter, and space of the spark plug. The exact spacing of the spark plug will be mentioned in the user manual.

5. Clean the new spark plug and place it neatly to ensure it fits properly.

6. Tighten the spark plug and put the cap back on.

These were the steps you need to follow when you want to change the spark plug of your bike. Remember that if you notice any abnormality with your bike and experience trouble while driving, it is best to get it checked by a mechanic. Invest in bike insurance to safeguard yourself against the cost of repair and maintenance. Bike insurance adds value to your bike and helps you gain a better riding experience with more focus on security and less financial stress.
