When a bike doesn't start, the spark plug is the first thing that comes to mind. The spark plug aids in the spark that ignites the engine. Therefore, your motorcycle won't run if the spark plug isn't installed properly. Therefore, understanding how to maintain a spark plug is crucial so that your travel can go without a hitch. You may take care of the spark plug with your bike insurance policy. Consider buying a comprehensive two-wheeler insurance policy to deal with issues of spark plugs. Besides, the policy will have a mandatory third-party cover, allowing you to ride your motorcycle without any legal concerns. Let's check the function of the spark plug and why it is important to care for it. Besides, you can know when to replace spark plugs if the situation tells you to. Let's get started!

What is Spark Plug?

A spark plug is responsible for igniting the pressurized air-fuel combination in an engine's combustion chamber. Manufacturers recommend replacing spark plugs at regular intervals. However, low fuel quality and dust may necessitate periodic cleaning. 

While most mechanics and riders focus on the engine, the most vital part of the engine- the small spark plug- is frequently overlooked. Keep in mind that an engine without a spark plug is useless. As a result, it is critical to maintaining the spark plug properly.

Perform a regular spark check to verify whether the engine is working correctly and when to replace those plugs. Cleaning the spark plug of impurities such as dirt and grime, as well as any oil residue, will go a long way toward maintaining a healthy spark. 

Why is it Important to Care for Bike Spark Plug?

The most common cause of difficulties starting is damaged spark plugs. The role of the spark plug in adequately operating the internal engine is critical. Spark plugs are the most crucial component of your motorcycle and are considered a life source in an engine.

The spark plug should be maintained because it is responsible for various critical tasks such as idling, acceleration, power, and fuel consumption. If dirt collects within the spark plug and causes sputtering noises, it will not work. Thus, for the optimal operation of your bike, perform a spark plug check regularly.

Tips on How to Take Care of Bike Spark Plug

Here are some tips you should follow to take care of the bike spark plug

  • Remove the cap of the spark plug very carefully.
  • To properly evaluate the spark plug condition, pick a clear cloth and clean up the place surrounding the plug.
  • Remove the spark plug with a plug spanner and inspect the spark plugs. Oil deposits around the plug tip indicate that the engine is not performing optimally.
  • Immerse the plug in gasoline or kerosene for cleaning, and then wipe it clean with a dirt-free towel.
  • Refer to the handbook for the proper suggested space. The electrode gap remains typically between 0.8mm and 1.2mm.
  • After thoroughly cleaning and inspecting, carefully replace the spark plug with the spark planner.
  • All these suggestions will assist in keeping the spark plug clean and running correctly, resulting in more smiles per mile. Apart from these, you should keep in mind the following points :
  • Each manufacturer defines plug types based on the specific characteristics of their engines. As a result, manufacturers recommend a standard plug specification based on the thermal range that the plugs require. Use only the type and make recommended by the manufacturer. Using the incorrect type of sparkplug can result in poor engine ignition and, in extreme situations, detonation.
  • The air-to-fuel ratio in the cylinder's explosive mixture can also affect your plugs. Lean mixtures place an undue strain on the plugs, resulting in more significant wear and tear. Unnecessarily rich mixes can induce pre-detonation, which can cause valve pinging and damage to your valves, piston and plugs. Check that the air/fuel ratio is set to the manufacturer's specifications. Over-advancing ignition time can cause plugs to burn or cause significant erosion. Changes to camshaft profiles or cam lobes can indirectly affect sparkplugs.
  • The spark plug cord is also essential since it transports the electric charge into the plug. Cracked, damaged, or worn-out cords must be replaced quickly to prevent energy leakage. The spark plug cap also helps keep the spark plugs dry and clean. As a result, cracked caps should be avoided. Keep an eye on the cord's length as well. It must be just the appropriate length to prevent the cap from falling off the plug if it is stretched too tightly. Look to change cords and plugs simultaneously.
  • Ensure that the plugs are removed and replaced using only a spark plug spanner. Also, ensure the threads are properly aligned and the plug is firmly screwed in. Avoid overtightening the plug, as this may cause thread damage.

If you have bike insurance, you can get the spark plug replaced regularly after a certain period.

When Should You Replace Your Spark Plug?

Replace the spark plugs on most motorcycles every 15,000 to 16,000 miles. However, if your bike is stuttering, running rough, or losing power, check spark plugs and, if necessary, change the same. If you buy an old motorcycle, especially one that has been sitting dormant for a while, you should inspect the spark plugs. Please inquire with the previous owner when they were last altered. If they do not recall, the best alternative is to replace them.

You can take two-wheeler insurance to get the spark plug changed and maintained regularly. You can opt for bike insurance online through Paytm Insurance.


The spark plug can be simply maintained by following the instructions outlined above. If the spark plug displays unusual wear after cleaning, look to replace it. Replacing spark plugs is a simple maintenance task you can easily accomplish.

1. How should spark plugs be cared for?

Check the spark plug regularly to determine whether the engine is working correctly and know when to replace it if necessary. Cleaning the plugs and removing the impurities such as dirt and grime, as well as any oil residue, will help maintain the spark plug healthy and fine.

2. When should spark plugs be changed?

A spark plug is responsible for igniting the pressurized air-fuel combination in an engine's combustion chamber. Manufacturers recommend replacing spark plugs at regular intervals. However, low fuel quality and dust may necessitate periodic cleaning.

3. Can I clean spark plugs with petrol?

Yes, you can clean spark plugs with petrol.

Eliminate the carbon particles from those spark plugs using a wire brush and immerse the plugs in petrol or vinegar for a couple of seconds to slowly eliminate the carbon particles.

4. How long should the life of a spark plug be?

The everyday life of a conventional copper spark plug is 10,000-20,000 miles. Silver plugs, utilized in older automobiles, have a lifespan of up to 20,000 miles. Iridium or platinum spark plugs, which are more expensive, can last 60,000 miles. Long-life spark plugs can last 100,000 miles.

5. What happens if your spark plugs aren't changed?

When the spark plugs are not changed, they do not produce enough spark. As a result, the combustion of the air/fuel mixture is incomplete, resulting in a loss of engine power, and, in the worst-case situation, the engine will not start.
