Step-1: Signs That Help Identify Flooded Dirt Bike Or Not

Before you take any action, first find out if your bike is stopped due to flooding or not. Here are some common symptoms to find out:

  • If you get a normal sound while starting the flooded dirt bike, you won’t be able to start your bike.
  • You will get a strong smell of oil from the cylinder in which excess oil has been stored.
  • You will see the leaking of gas from the exhaust and carburetor. 

These are the three symptoms that will ensure your bike does not start due to flooding. If you find the actual problem of a non-starting engine, you can easily solve the problem. Though it’s a hassle, it can be solved easily.

Step-2: Turn Off The Petcock

Firstly, you need to turn off the petcock. By doing this, your engine will be secured by not adding more fuel when you crank it for a few minutes. Once the dirt bike engine gets secured, you can head to the fuse removal step after blocking the petcock. 

Step-3: Remove The Fuse

Secondly, you may notice there is a fuse that goes to the ignition coil. You need to remove that fuse. Though some people do not prefer to remove it, my suggestion is to remove it for your safety. You may get shocked by some of the wires. 

Step-4: Remove The Spark Plug

After removing the coil fuse, you need to remove the spark plug. At this stage, you have to check their condition. You need to ensure that there shouldn’t be any corrosion. There should be a gap between the spark plug and the hook at the end.

Step-5: Collect Old Clothes To Clean

At this stage, you need to collect some old clothes. Clean the spark plug holes by placing cloth inside. Make sure the cloth shouldn’t get stuck there. While cleaning the spark plug, you need to be careful about the dust and debris which should not get stuck inside. 

There should be space for air to flow. If you have compressed air, it can help dry extra fuel. Another thing that you can do is leave them under the sun for 10-15 minutes to dry. 

Step-6: Reinstall The Spark Plug

Now, you need to reinstall the spark plug. If needed you had better use a plier to adjust. This process is not very hard. If you have a spare plug available, it’s better to use that. If this part is not installed properly, there is a chance of a flooded bike again. There should be a gap between the spark plug and the hook at the end which is about 0.28 to 0.32 in (.07mm to .08mm)

Step-7: Start The Flooded Dirt Bike

This is the last step to follow. After reinstalling everything, start your bike again. Your bike should start within four to five kicks.
