Steps to Gap Dirt Bike Spark Plug
Below are the steps you need to follow in order to gap your dirt bike spark plug:
1. Remove the spark plug from the engine
The first step is to remove the spark plug from the engine. Be careful not to drop it and damage the ceramic core!
2. Measure the plug gap
Use a spark plug gap tool or feeler gauge to measure the plug gap. This is the distance between the center electrode and the ground electrode.
3. Adjust the gap as necessary
If the gap is incorrect, you can use a spark plug gap tool to adjust it. Be very careful when doing this, as you can easily damage the spark plug if you’re not careful.
4. Reinstall the plug
Once the gap has been adjusted, reinstall the spark plug into the engine. Make sure that it’s properly tightened so that it doesn’t come loose.
And that’s it! You’ve now successfully gapped your dirt bike spark plug.
So, Why does the gap matter?
The gap between the center electrode and the ground electrode affects the performance of your engine in a few ways:
– It controls the spark intensity
– It determines the amount of voltage required to fire the plug
– It influences the duration of the spark
All of these factors play a role in how well your engine runs, so it’s important to make sure that the gap is set to the correct specification.
What happens if the spark plug gap is too big?
If the gap is too big, the spark will be too weak to ignite the fuel/air mixture in the engine. This can cause a number of problems, including:
– Poor fuel economy
– Rough running engine
– Black smoke from the exhaust pipe
– Reduced power and acceleration
– Increased emissions
What happens if the spark plug gap is too small?
If the gap is too small, the spark will be too intense and it could damage the electrodes in the spark plug. This can lead to:
– Engine misfiring
– Reduced engine performance
– Plug fouling
– Increased emissions
As you can see, it’s important to make sure that the gap is set to the correct specification. By following our guide, you can easily do this yourself.
