Just like with most of the motorcycle cleaning products you’re shopping for, carburetor cleaners each have their own features distinguishing them from one another. When you’re shopping for a quality motorcycle carb cleaner, you want to have all the information possible to make sure you’re getting the right one for the job.

To make it easier for you to find the right product, you put together this helpful buyer’s guide. With this information you’ll be well informed on choosing the best carpet cleaner, regardless of your motorcycle model.

This section will help you with some tips on how to pick the best carb cleaner. You’ll also learn more about the features to look for to find the right product for your needs.

Why You Should Use a Motorcycle Carb Cleaner

The problem with motorcycle carburetors is that they can regularly get choked by oil, carbon deposits, and sludge. When this happens, fuel is prevented from smoothly moving into the combustion chamber.

This causes the fuel to take more time to burn and results in waste. The performance of the motorcycle engine is also affected.

Using a quality carb cleaner will remove these carbon deposits and other unwanted materials in the carburetor. They’ll also help to enhance the speed of fuel movement and improve combustion.

Chlorinated carb cleaners can clean the entire engine. This includes cleaning the fuel injectors and valves, which will boost fuel efficiency.

The way these motorcycle carb cleaners work is through a mixture of powerful chemicals. These chemicals react with the carbon deposits and dirt that’s left behind in the carb. The dirt and deposits are broken down by these chemicals, which enhances the performance of the engine.

With a dirty carburetor, the motorcycle engine won’t function properly. The deposits of carbon and sludge will slow down the motorcycle acceleration and affect overall performance. Using a quality carb cleaner will remove all the dirt in the engine system, clean out the carburetor, and enhance fuel flow while making the bike easier to start and accelerate.

To summarize, these cleaners will remove all the dirt and carbon deposits in the carb. They’ll help the motorcycle engine save on fuel while preventing hard starts and improving the bikes acceleration.

Types of Motorcycle Carburetor Cleaners

Depending on the manufacturer, there are different types of carb cleaners available. Always check that the brand you’re interested in is compatible with your bike.

Let’s take a look at some of the basic types of motorcycle carb cleaners you can find:

Chlorinated vs Non-Chlorinated

Chlorinated carburetor cleaners use chlorine in their solvent formula. This is only suitable for certain types of carbs and engines. Chlorine is a very active solvent and can damage the carburetor, if used improperly or on the wrong carb.

Non-chlorinated cleaners do not contain any chlorine in the formula. Most carb cleaners do not contain any chlorine, due to the damage it can cause to the smaller parts of the carburetor and motorcycle engine.

Non-chlorinated carb cleaners can also be used in a variety of applications. Along with the carburetor, they can be used to clean smaller components of the engine, such as the valves and fuel injectors.

Compatible vs Non-Compatible

Depending on your motorcycle carburetor, the cleaner may or may not be compatible. Look for this rating when you’re browsing different carb cleaners.

Compatible carb cleaners are universal and designed to be used on different types of motorcycle carburetors. The compatible type won’t affect engine performance negatively.

Non-compatible carb cleaners are made for specific types of carburetors. These are designed to be used with specific motorcycle brands.

Compared to non compatible cleaners, the compatible carb cleaners are more affordable and easier to find. Most of them also come with a built-in nozzle, for easy and quick application.

Motorcycle Carb Cleaners Features to Look For

When you’re looking for a quality carb cleaner, there are some different features and characteristics to keep an eye out for. Always start by checking that the cleaner is suitable for your motorcycle brand.

Here are some other key elements and features to keep an eye out for:

Construction of Your Carburetor

The first thing to consider is the material used in the construction of your carburetor. Some parts of the car are made of plastic, rubber, and soft metal, parts that can easily damaged if you’re using a carb cleaner with a strong solvent.

If you’re worried about the construction of your carb, your best bet is to use a non chlorinated cleaner. These are safe to use on a wide range of different materials, including the sensitive materials that you might find in your bike.

Chlorinated carb cleaners should be used with any soft rubber or plastic materials. To avoid damaging your carb, find the right cleaner that’s suitable with the materials found in your motorcycle.

Safety

When you’re shopping for a carburetor cleaner, look for one that comes with safety features. These features make the cleaner easier and safer to use for maintaining your motorcycle carburetor.

For example, look for nozzle funnels, sprays, or dips. Don’t forget to check the ingredients, to make sure you’re not allergic to anything inside. You should also choose a product that’s safe on your hands, although it’s a good idea to wear gloves either way.

Riders with a standard carburetor do not need a carb cleaner that uses powerful, dangerous chemicals. These could put your health at risk and they’re not required in most cleaning conditions.

Ease of Use

With so many different cleaners to choose from, you want to look for one that’s easy to use. There should be an instruction manual included as well as an easy to open seal, for faster application.

Any of the cleaners you’re using should be easy to open and large enough to handle. Check reviews and the product description to make sure you’re using a safe product that’s easy to use.

HEST Rating

The HEST rating relates to the technology in the carb cleaner. It’s a feature that helps the cleaner remove deposits and dirt in the carburetor, without affecting its operation.

Keep an eye out for the HEST rating as it lets you know you’re buying a quality product. Having this feature supports fuel combustion and helps your motorcycle engine to enhance acceleration and save on fuel costs.

Tips for Buying and Using Motorcycle Carburetor Cleaners

It can be challenging to buy the right carb cleaner, especially if you don’t have the skills or experience with this process. You need to know that a quality carb cleaning spray or foam should be able to break down all the dirt, sludge, and carbon deposits inside the carburetor.

It needs to have a higher dissolving capacity, which helps to break down complex deposits and help prevent them from forming in the engine system. Most of the cleaners will also improve engine performance and fuel economy as well.

Most riders prefer using mutli-fabric cleaners, as they’re more powerful and effective at removing dirt and varnish in a carburetor. This type ensures the motorcycle carb keeps running in excellent condition, as well as the rest of the fuel system.

Another factor to consider is the affordability of the cleaner you’re interested in. Most standard carb cleaners are reasonably priced and will provide you with more than one use. You’ll find that the non-chlorinated cleaners, or those that double as a fuel additive, will be a bit more expensive.

Other helpful tips include:

  • Check for the HEST rating
  • Ensure that the price is within your budget
  • Check the ingredients to see if they’re safe or if you’re allergic to any
  • Only use cleaners that are from quality manufacturers
