While most mechanics and riders pay attention to the engine of the bike, at times one ends up ignoring the most important part in the engine- the modest spark plug. Remember that an engine without a spark plug is as good as a heap of junk. Therefore, it is important to take proper care of the spark plug.

Damaged spark plugs are the primary cause of hard starting. For the correct working of the internal engine, the role of spark plug plays is important. Spark plugs are the most important part of your bike and are regarded as a life source in an engine. One should take care of the spark plug as they are responsible for performing several key functions such as idling, acceleration, power, and fuel consumption. The spark plug for your bike will not work if the dirt collects within it and make sputtering noises. Thus, carry out a spark plug check from time to time for the proper functioning of your bike.

Tips On How To Take Care Of Bike Spark Plug

Cleaning the spark plug of dirt and grime and cleaning the oil residual will go help in keeping the bike in good physical shape. Mentioned below are the tips to follow for spark plug:

  • Remove the spark plug cap carefully
  • Use a dirt free cloth to clear up the place near the plug to correctly inspect the spark plug status.
  • Eliminate the spark plug using a spark plug spanner and then check the status of spark plugs. Black crust or oil deposits or near the plug tip indicates the engine is blazing at less than perfect condition.
  • Dip the plug in kerosene or petrol and then give it a clean wipe with a dirt-free, dry cloth.
  • Check the manual for the accurate suggested gap to be maintained amid the electrodes. Typically, the electrode gap is 0.8mm to 1.2mm.
  • Once the cleaning and examination is done, fit the spark plug back into its position with the assistance of the spark plug spanner. Keep in mind not to tighten it too much as it can damage the threading and further augment your hassle.

All these tips will help keep the spark plug clean and functioning competently resulting in more smiles per mile.

A bike is a beloved asset of every bike fanatic. Thus, it is important to maintain the bike in good condition and also vital to know the basic repair process in case of any mechanical issues in the middle of the road.

How Often Should The Spark Plug Be Replaced?

For most bikes, replace the spark plugs every 15,000 to 16,000 miles. However, if your bike is sputtering, running rough, or is losing power, spark plugs should be examined and replaced if necessary. If you have purchased a used bike, especially one that has been sitting idle for a while, then you should examine the spark plugs. Ask the previous owner the last time they were changed. If they do not recall, then replacing them is the best option.


By following the aforementioned steps, one can take care of the spark plug easily. If the plug shows bizarre signs of wear after cleaning, then it is recommended to replace the spark plug. Replacing the spark plugs is an easy maintenance job you can often do yourself.
