This Year’s Buying Guide
Given the multitude of products available on the market, finding the best carburetor cleaner for motorcycle is not the easiest of tasks. On top of that, simply finding an item is not enough. You need to consider your knowledge of carb cleaning, and start from there.
Besides this, there are other things to take into consideration, to make sure you offer your motorcycle the best treatment possible.
Understanding why only the best will do
Not all of us are knowledgeable when it comes to motorcycle parts and their support. We know that any vehicle needs maintenance, but what does this involve exactly? There are a number of parts you need to check regularly and one of them is the carburetor.
It is essential to have the carb working properly at all times, and for that, you need the best carburetor cleaner you can find.
These cleaners work by removing the harmful deposits that might have gathered in the system. As a result, the overall performance of the engine will be better.
High Energy Solvent
Now that we mentioned the importance of using a high-quality product, there are some things to look for when purchasing it. One of those features is the High Energy Solvent Technology or HEST, as it is essential in order to improve the fuel efficiency but also the vehicle’s drivability.
The HEST technology is developed to clean the entire fuel system of the engine. This means all parts, from the gas tank to the combustion chamber. This feature actively supports combustion for all types of gasoline.
A motorcycle’s dirty fuel system can result in numerous engine issues, including hard starting, rough idling, and no fuel economy. If you are unsure of whether a product has been formulated with the HEST technology, the most effective way to find out is to read the label.
Multi-fabric content, deposit remover and dissolving capacity
The multi-fabric content feature is very sought after because it means that the cleaner will offer increased performance for the carburetor system, the fuel injectors, and the intake valves. Usually, a good carb cleaner will be able to take care of the entire fuel system.
Another important feature of a good carb cleaner is its capacity to dissolve the various deposits that have gathered in the carburetor, such as gums, gunk, and other harmful sediments.
With such a product, the deposits are first dissolved and are later eliminated through combustions. Besides dissolving the deposits, the cleaner itself should also be able to dissolve fast. It must not remain on the surfaces of various parts from the engine.
Just like sediments are harmful to the motor parts, residues from the formula can be harmful as well. The cleaner needs to dissolve quickly, leaving behind only clean parts.
Chlorinated vs. Non-Chlorinated
When it comes to cleaning the deposits off your carburetor, choke, and throttle body, these are the two most popular choices. They will both get the job done, but it is important to understand the key differences in order to avoid maintenance and safety issues. Chlorinated and non-chlorinated cleaners both contain toxic chemicals.
Between the two options, the chlorinated ones include more destructive elements. They are made from methylene chloride, trichloroethylene, and perchloroethylene. These names may not tell you much, especially if you are not a chemist, but we’ll tell you that they are regarded as volatile organic compounds.
The non-chlorinated solvents contain more environmentally friendly compounds such as acetone, low toxicity petroleum hydrocarbons, isopropyl alcohol, and heptane. In case you were wondering what it is with this chemistry lesson, you should know that it is very important to remember that not all carb cleaners are compliant in all of the fifty states.
Hence, before making any purchase, you should make sure that you get an appropriate product. If you are undecided, or unsure, and you cannot find the information online, you can also ask a mechanic.
Carb cleaner kit and accessories
Last but not least, it’s essential for you to know that the cleaner is not enough when you decide to start washing your carburetor.
To be more exact, you will need a carb cleaner kit and gloves in order to correctly clean and rebuild your carburetor, choke, and throttle body. For better organization, we suggest you select a kit that comes in a ring.
This guide is meant to give you an idea of what features to look for when buying a new carburetor cleaner. With its help, we are sure you are going to find the most appropriate one for your needs.
Frequently asked questions about carburetor cleaners
Q: How to use a carburetor cleaner?
When you want to clean your carburetor, first, you should remove the air cleaner section from the engine by unscrewing the wing nut; if it’s very tight, you might need to use pliers. Then, you should vacuum off the top of the engine area; this step is needed to prevent debris and dirt from being absorbed into the engine when the air cleaner is not in place.
The next step is to spray the carburetor inside and out with a dedicated cleaner to loosen the varnish and gunk. You can use shop rags to wipe up heavy grease and gunk loosened by the carburetor cleaner.
Q: What is a carburetor cleaner?
A carburetor cleaner can either be a single-can aerosol or it can come in gallon-sized portion. These products are developed to help you clean your entire engine system.

Combined with premium gasoline or diesel, the results can be more effective and long-lasting. It is important to choose a carb cleaner that is compatible with your engine, and if you do not know too much about this stuff, it is best to ask a professional first.
Q: What is a carburetor cleaner made of?

Q: Do carburetor cleaners really work?
To keep things simple, the answer is yes! However, they cannot do all the work by themselves. Maintaining your engine does not involve using only cleaners. Changing the fuel filter, using premium gasoline with the appropriate octane rating for your vehicle, and also high-quality fuel additives are all key factors to a smooth running engine.
When added to fuel, these concentrated cleaners pass through the carburetor and injectors and loosen and remove accumulated varnish deposits. These sediments are burned up through engine combustion and the result is a noticeable difference in idle smoothness, emissions, as well as fuel economy.
