Best Motorcycle Carb Cleaner Buying Guide & FAQ

We have formulated an all-inclusive buyer’s guide to help you in choosing the best carb cleaner irrespective of your motorcycle model. We’ll give you some tips to help you pick the best carb cleaner if you are a first-time buyer or you are looking for a better one. Read on to find out what features you should look for in a carb cleaner before placing your order. 

Benefits of a Motorcycle Carb Cleaner 

In most cases, your motorcycle carburetor gets choked by oil, carbon deposits, and sludge that prevent the fuel from smoothly moving to the combustion chamber. This results in waste and the fuel takes more time to burn. A quality carb cleaner removes all the carbon deposits in the carb to enhance the speed of fuel movement and combustion. 

A chlorinated carb cleaner will clean the entire engine, including the valves and injectors, to boost fuel efficiency. When used as a fuel additive, a carb cleaner reduces the boiling point of diesel and LPG to save on fuel.

Motorcycle carb cleaner is a mixture of powerful chemicals that react with the carbon deposits and dirt present in the carb. It breaks the stubborn dirt down to enhance engine performance.

A dirty carburetor stops the engine from functioning optimally or at the required acceleration. The carbon deposits and sludge in the carb will slow down the acceleration of the motorcycle. A quality carb cleaner removes all the dirt in the engine system and enhances the fuel flow, making it easier to start and accelerate.

Benefits 

  • It helps your motorcycle engine save on fuel.
  • It removes all the dirt and carbon deposits in the carb.
  • It prevents hard starts and improves the bike’s acceleration rate.  

Types of Motorcycle Carb Cleaner 

There are plenty of carb cleaners from different manufacturers. When choosing a carb cleaner, you must find out if the brand supports the motorcycle carb because some may not be compatible with your bike. Below are some basic types of carb cleaners you can find for your bike.

Chlorinated vs. Non-Chlorinated Carb Cleaners 

Chlorinated carb cleaners are those that have chlorine in their solvent formula. These types of carb cleaners are only suitable for some brands of carbs and engines. They are very active and can corrode the metal surface of the carburetor if used for too long.

Conversely, non-chlorinated carb cleaners are those that do not contain chlorine in their formulation. They are the most common types of carb cleaners you will find. They do not cause any damage to the smaller parts of the carburetor and motorcycle engine system. You can use the non-chlorinated carb cleaner for the smaller components of the engine system, such as fuel injectors and valves.

Compatible vs. Non-Compatible Carb Cleaners 

Carb cleaners can be compatible or not compatible with your motorcycle carburetor. A compatible carb cleaner is universal, which means you can use it to clean different types of motorcycle carburetors without affecting the engine performance. 

On the other hand, non-compatible carb cleaners are those that are made for specific types of carburetors. You can only use them on a given motorcycle brand. Compatible carb cleaners are easy to find and affordable compared to non-compatible carb cleaners. They are also easy to use and may come with a built-in nozzle for quick and easy application.

Features to Look for in Motorcycle Carb Cleaners 

Carb cleaners come with different characteristics that distinguish them. When buying a quality carb cleaner, you must check for the unique features that make it suitable for your motorcycle brand. The following are some of the key elements that you should look out for when buying your carb cleaner.

  • Construction of Your Carburetor

The material used in making the carburetor should be the essential factor to consider when purchasing a carb cleaner. Some parts of the carburetor can be made of rubber, plastic, and soft metal that will easily corrode if you apply a carb cleaner with a strong solvent. 

If you are not sure about the materials used in the construction of the carburetor, you can go for non-chlorinated cleaners, as well as those that work on multiple types of material. Chlorinated carb cleaners are not suitable for cleaning carburetors with soft rubber and plastics. Therefore, to ensure you don’t damage your carb cleaner, you must ensure you get one that is suitable for your carburetor’s material.

  • Safety 

When buying a carb cleaner, you must ensure it is safe to use. A typical carb cleaner should come with a nozzle funnel that makes it easier to apply. You can also go for carb cleaners with sprayers or dips that will make it safer to use. Also, check the ingredients used to make the carb cleaners if you are allergic to them. Choose a carb cleaner that is safe on your hands.

If you have a standard carburetor, then you do not need a carb cleaner with dangerous chemicals. Some retailers may sell you carb cleaners with more powerful and hazardous chemicals that might put your health at risk.

  • Ease of Use 

This is an essential factor to consider before you can buy a quality carb cleaner. It should be easy to use, even by beginners. The carb cleaner should come with an instruction manual to guide you on how to use it. It should also have an easy-to-open seal for faster application. 

Some carb cleaners come with extra tight seals that make them difficult to open. A standard carb cleaner should be easy to open, lighter, and larger enough to last longer. Also, it should be safe and faster to use. You should be able to pull out the carb cleaner from the shelves and start using it without contacting your mechanic for help.

  • HEST Ratings

HEST is another essential feature that you should look for when buying a carb cleaner. A carb cleaner with a higher HEST rating will enhance the motorcycle’s drivability and fuel efficiency of the engine. HEST is the technology that helps the carb cleaner remove all the deposits and dirt in the carb without affecting its normal operation. Carb cleaners with this feature will support fuel combustion and help your motorcycle engine save on fuel and enhance acceleration.

Tips for Buying and Using Motorcycle Carb Cleaners

Buying a carb cleaner can be a bit challenging if you don’t have some skills and advice to help you in the process. It is vital to know that a quality carb cleaner should be able to dissolve all the dirt, carbon deposits, and sludge inside the carb. That means it should have a higher dissolving capacity to break down the complex deposits and help in their emission from the engine system. 

Most motorists prefer multi-fabric carb cleaners because they are more powerful and useful for removing all the dirt and varnish in the carb. A carb cleaner with multi-fabric content will always ensure your motorcycle’s carburetor is in excellent condition because it will take good care of the entire fuel system. 

Affordability of the carb cleaner is also something you must also check to find out if it fits your budget. A standard carb cleaner for removing carbon deposits in the carb should not be that expensive unless it has some other features that make it unique. For instance, carb cleaners that double as fuel additives can be a bit pricey. On the other hand, non-chlorinated carb cleaners are too expensive. When choosing a carb cleaner, you should go for one that is not very expensive or the cheapest. Always shop for a carb cleaner that guarantees you quality and performance.

  • Check if the carb cleaner is HEST rated.
  • Ensure the price of the carb cleaner is within your budget.
  • Find out the ingredients used to make the carb cleaner.
  • Only buy carb cleaners with quality and safety assurance.
