What To Consider When Buying Motorcycle Carb Cleaner

Carb cleaner kit and accessories

Another essential factor to consider is the kit and accessories. This guide is to give you an idea of the accessories that your package must contain when buying a carb cleaner.

Know whether the kit and gloves are sufficient to correctly clean and rebuild your carb, choke, and throttle body. It is better to use a kit that comes in a ring.

Speediness of the Carb Cleaner

It’s important to take speediness and effectiveness side by side when considering which carb carburetor to buy. Some cleaners will get the job done in a matter of minutes; others may take a longer time.

If you’re running on schedule, the better option is to opt for the cleaners that act fast. Within minutes, the job is done on your carb.

Alternatively, if you have all the time in the world, you can go for the thorough cleaning of vehicle carb. Preferably, go for the carb cleaners that effectively work when applied overnight.

 Note, speediness doesn’t mean shoddiness; whereas, time taking does not suggest effectiveness. It all depends on who handles the two processes.

Effectiveness of the Cleaner

I think the reason for applying carb cleaner on your bike is to have a squeaky clean carb, right? A cheap carb cleaner may be more effective than its pricey counterpart. As much as possible make sure the cleaner you’re buying has all the essential properties and features to get rid of all gunk and varnish deposits from your carb.   

Type of Carb Cleaner

To avoid maintenance and safety issues, find out if the chlorinated or non-chlorinated carb cleaner is suitable for your vehicle. They’re the two options available and they both contain toxic chemicals.

However, the chlorinated ones contain more dangerous elements (such as methylene chloride, trichloroethylene, and perchloroethylene) and are volatile, whereas, the non-chlorinated solvents are more eco-friendly and less toxic. They contain acetone, low toxic petroleum, heptane, and isopropyl alcohol.

Quality of Features of Crab cleaners

Before you buy your motorcycle carb cleaner, make sure you weigh the following essential features, namely, multi-fabric content, deposit remover, and dissolving capacity.

Carb cleaners with multi-fabric content features offer increased performance on your carb, fuel injector, and intake valves. Overall, it does an incredible job on the entire carb system.

A good carb cleaner should also have the capacity to dissolve and eliminate the various gunk and varnish deposits through combustions. Besides, the cleaner should be able to dissolve fast. Residue sediments from the formula can be as harmful as the deposits.

Frequently Asked Questions

What is a carburetor cleaner made of? The ingredients of bike carburetor cleaners actually vary from product to product. However, generally speaking, the components of a carb cleaner are often derivatives of fossil fuel. This chemical compound found in geological locations appears in various forms in the carb cleaners.

One of the petroleum products found in bike carb cleaners is acetone. It is often used due to its osmotic properties. Another petroleum product used in making carb cleaner is methyl ethyl ketone, which is used because of the ability to clean and remove excess grease or lubricant. Ethylbenzene is also used because it removes the resins found in dirty carbs.

Other petroleum products found in carb cleaners include xylene (for its clarity and ability to dissolve easily), propane, and 2-butoxyethanol.

What is a carburetor cleaner? It’ll absolutely be out of place if I fail to describe a carburetor cleaner. Existing either as a single-can aerosol or in a gallon-sized portion, a carb cleaner helps you to clean your entire bike engine system, removing all debris and dirt.

Depending on the chemical mixture used in a cleaner, a carb cleaner is expected to dissolve the gum, varnish, and other unwanted deposits that gather around the carb. The formula should also degrease the carb.

However, the formula works better, lasts longer, and is more effective if blended with some diesel or premium gasoline. Needless to mention, not every carb cleaner is compatible with your bike engine. Ensure you consult your repairman to know which is perfect for your bike.

How to use a carburetor cleaner? Please, bear in mind that you can clean your carb without removing it. However, if you must remove the carb, it is a no-brainer. Follow these easy-to-implement steps:

  • Remove the air cleaner section from the engine (you can either use a screw driver or pliers to unscrew wing nut, depending on the tightness of the nut).
  • Evacuate the top of the engine area to prevent the engine from absorbing debris and dirt (when the air cleaner is out of place)
  • Spray the carburetor inside and out (use a recommended carb cleaner) to get rid of the gunk
  • Wipe up heavy grease released by the carburetor cleaner.

Do carburetor cleaners really work? Yes, carb cleaners really work. Don’t underestimate the need to maintain your motorcycle engine. The carb cleaners can’t do it all alone. Don’t hesitate to study how a motorcycle engine works. Complementing the effectiveness of the carb cleaners requires that you change the fuel filter of your vehicle. Besides, use top-quality fuel additives and premium gasoline with the right octane rating.

Essentially, if all these other factors are in place, the carb cleaner helps to free and remove accumulated varnish and gunk deposits in the engine. The result is that the engine produces incredible idle smoothness while maintaining fuel economy.

Final Thoughts

It’s not always advisable to presume or assume anything when it comes to buying motorcycle carb cleaners. Neither works with probability or without evidence. Buying and using a carb cleaner on your engine is analogous to using drugs in the body. If it’s not the right prescription, it backfires, and quite dangerously.

When it comes to using carb cleaner, the rule applies. If you fail to use the best motorcycle carb cleaner on your bike, the consequences are damaging to your bike engine and telling on your finances, as well. Is it not better to be penny-foolish and pound-wise? I think it is. Hence, if you want to splash your hard-earned money on any carb cleaner, choose any of the ones I have described above. Anything outside these, I can assure you may be buying a sheep in the poke. And you know how dicey that can be.
