Changing a spark plug is one of the most straightforward ways to maintain your dirt bike’s engine in shape. Timely replacement of spark plugs is vital for the efficient functioning of your dirt bike as it helps in igniting the fuel-air mixture. In this blog post, we’ll dive into how to change a spark plug on a dirt bike. Whether you’re a seasoned rider or a newbie, this step-by-step guide will be helpful in providing the necessary guidance.
Why and When To Change the Spark Plug
Spark plugs play a critical role in your motorcycle’s operations. They ignite the fuel/air mixture in the combustion chamber to make the engine run. And just like any other components of your motorcycle, spark plugs get damaged over time. So when does it mean it’s time to change them? This blog post will help you determine when it’s time to replace your motorcycle spark plugs and why it’s necessary.
1. Mileage: Your motorcycle’s owner’s manual comes with a maintenance schedule that includes changing the spark plugs at specific mileages (usually between 5,000 to 10,000 miles). If you don’t ride your motorcycle that often (or you only ride it during weekends), consider changing the spark plugs once a year.
2. Rough Idle: When your motorcycle is idling, do you notice roughness, stalling, or misfiring? This could indicate that your spark plugs aren’t working correctly. If left unattended, this problem could lead to more significant issues such as poor fuel economy or damages to the exhaust system.
3. Poor acceleration: If you notice that your motorcycle doesn’t accelerate as quickly as it usually does, the issue could stem from worn-out spark plugs. It’s best to replace the plugs to restore your bike’s performance.
4. Difficulty starting: If your motorcycle has trouble starting up, especially when the engine is cold, the culprit might be your spark plugs. Without a healthy spark, the engine won’t get enough power to start.
5. Fuel economy: Lastly, consider your motorcycle’s fuel economy. Are you refilling the gas tank more frequently than usual? Then it could mean that your spark plugs are causing more fuel consumption than necessary. Changing the spark plugs can save you money in the long run.
Spark plugs may seem like small components, but they are essential in keeping your motorcycle running smoothly. Knowing when to replace them can help you avoid costly repairs and lengthen the lifespan of your motorcycle’s engine. If you have any doubts about the health of your spark plugs, it’s best to bring your bike to a professional mechanic. They can assess the situation, recommend replacements, and ensure your motorcycle runs well for miles and years to come.
How To Find a Replacement Spark Plug for Your Dirt Bike

The OEM spark plug may cost slightly more than the aftermarket alternatives, but it is worth knowing that it’s a genuine product that’s guaranteed to work correctly with your dirt bike.
5. Don’t Ignore Changing the Spark Plug
Finally, it’s essential to note that spark plugs wear out and need replacement. Most manufacturers recommend replacing the spark plug on your dirt bike after every 100 hours of use or once a year, whichever comes first.
