When you notice that your motorcycle is not running smoothly, it is time to clean your carburetor. Refill the fuel tank completely and add 1 ounce of seafoam per gallon to clean the carburetor. Then shake the motorcycle a little and mix fuel and seafoam, and do a test ride for an hour compactly. As a result, you will see thick white smoke, which means seafoam is cleaning your carburetor.

Regular cleaning of the carburetor can make your motorcycle run smoothly for a long time. Experts recommend cleaning the carburetor regularly. Here I will discuss how to clean the carburetor using seafoam in two ways without separating it from the engine. 

2 Easy Ways To Seafoam A Motorcycle Carburetor:

It is a very popular material for cleaning the carburetors of motorcycles. Seafoam helps keep the carburetor clean, but the best way to clean it is with a carb cleaner.

Anyway, the 2 methods I will tell you about here will help you keep the motorcycle carburetor clean and long-lasting. Let’s learn without further ado! 

Method 1: Seafoam With Fuel

An easy way to use seafoam on a motorcycle is to combine it with fuel. It can easily eliminate dirt from the carburetor. Seafoam and fuel can be mixed to clean your motorcycle when it isn’t running smoothly as before. However, let me know the whole process so that your work becomes more accessible.  

Step-1: Refill your fuel tank

First, refill your motorcycle’s fuel tank so that no part of the tank is left empty.

Be sure to use the usual motorcycle fuel.

Step- 2 Add Seafoam

After filling the fuel tank, seafoam should be added to it. Fuel and seafoam can be

mixed earlier by pouring them into the tank. So, it is required to mix 1

an ounce of seafoam with every gallon of fuel.

Step-3: Shake Your Motorcycle

Once seafoam has been added to the fuel tank, the tank’s lid must be closed and the motorcycle shaken for a few seconds. As a result, seafoam will blend well with motorcycle fuel.

Step-4: Take A Test Ride

In this stage, you need to take a test ride for more than one hour, then test the motorcycle curb again. Seafoam removes dirt from the carburetor during riding by releasing bushy white smoke.

Step-5: Complete The Cycle And Check Engine

The engine must be kept running for a minimum of one hour for the carburetor to be completely clean. So turn on the motorcycle engine and wait to finish and ensure that it is enhanced. This process of cleaning should be repeated several times for the best results.

Method 2: Seafoam With Engine Oil

Now we will know another way to seafoam motorcycle carburetors. For this process, you need to mix seafoam and fuel. This is much easier than the first process, but it slowly removes dirt and debris from the carburetor. So let us know what to do to complete the second process.

Step-1: Pour Seafoam 

First, it is required to take away the cap of the fuel tank and pour the seafoam directly. One ounce of sea foam is needed for every gallon of fuel depending on the fuel in your tank. Use a straw to pour oil into the tank.

Step-2: Take A Test Ride

After pouring seafoam into the engine, the engine should be kept running for some time. You can take an experimental ride that helps clean your carburetor.

Step-3: Monitor The Oil Turns 

After applying seafoam in the oil tank, it should be monitored daily. As soon as fuel becomes black color, then change it with fresh fuel, and repeat this process if necessary. 

9 Tips To Use Seafoam In A Motorcycle Carburetor:

While using seafoam in a motorcycle carburetor is not a difficult task, a few tips will make your job easier. Here are a few tips that will help you apply seafoam to your carburetor as well as clean it thoroughly.


If you wish, you can remove the carburetor bowl and use seafoam to clean it. To do this, remove the bowl, mix in half the amount of fuel and seafoam, and let the mixture rest until it is finished. Then leave it overnight with 100% seam in it, and the next day drain and deactivate the bowls by adding 8 to 9 capful seaweed to the tank.


The fuel tank must be refilled entirely to clean the carburetor. If you do not fill the tank, the seafoam will not be able to enter the entire carburetor, so it will take a long time to complete the cleaning work.


If you remove the carburetor and apply seafoam, you must thoroughly clean and reinstall all parts of the carburetor. This will allow your motorcycle to ride more smoothly and will last longer.


If you ride the motorcycle regularly, you should clean the carburetor using seafoam at least once after 6 months, in addition to proper maintenance. If you do not clean the carburetor for a long time, your motorcycle will become uneven, and the stability of the engine will be reduced.


Using one ounce of seafoam per gallon of fuel is recommended to clean the motorcycle carburetor. However, you can increase the amount of seafoam and use two ounces. It works faster and is better to use a little more seafoam.


Although I’ve talked about adding seafoam to fuel in one way or another, you can add two different ingredients. Although it is easy to mix seafoam directly into the fuel tank, you can also make a mixer with fuel and seafoam in a container.


If you use seafoam without removing motorcycle parts, you need to take a test drive to keep the engine running for at least an hour after refilling the mixture in the fuel tank. Shake the motorcycle a little and go riding.


Although seafoam cannot do much for a motorcycle engine, keeping it on a motorcycle for long is not advisable. Therefore, the fuel should be cleaned within a few hours using the seafoam motorcycle; for best results, use it one hour before changing the oil.


Many people think that it is better to use only seafoam to clean the carburetor, but this is not true. Seafoam carburetor debris cannot be removed entirely, so first clean the carburetor using a carb cleaner and pour seafoam into the fuel tank one hour before changing the oil.
