A Snapshot of our Top Picks
But First an Intro to AFR for the Best Fuel management system for Harley Davidson
What does the Air Fuel Ratio (AFR) refer to?
Air Fuel Ratio, also known as A/F Ratio or AFR, refers to the amount of air and fuel that is to be injected into the cylinders. A lean air to fuel mixture means you have more air and less fuel, while a rich mixture means less air and more fuel in the mixture.
If you are using gasoline, the calculated air to fuel ratio to produce complete combustion is 14:7. Running your engine on a lean air to fuel ratio improves fuel economy such that you can ride for long without spending so much on fuel. On the other side, running your Harley Davidson bike on a richer ratio ensures you enjoy more power and cooler engine temperatures.
Why should you care about the air to fuel ratio?
If you strike a balance between the two, you can expect enhanced performance in your Harley Davidson. It also enhances mileage, and if you love speed, the right ratio ensures that your bike offers you the expected speed.
Additionally, a balance in the ratio also helps your bike last longer as it reduces wear and tear. By just maintaining a balance between the air and fuel ratio, your Harley Davidson bike serves you better, and you can also expect an extended useful life from the bike.
But everything happens in the engine. How do you ensure you maintain a proper balance while you can’t see what is happening in the engine?
What you need is an auto-tune device. However, the challenge is trying to get the best fuel management or autotune system while there are so many market options.
If you are looking for the best fuel management system for Harley Davidson, then you are in the right place. Here, we will give you our top three picks. The choices are a result of intense research and expert review.
You can trust our choices to enhance your Harley Davidson bike’s performance, speed, and durability.
Do you require a fuel management system?
Motorcycle manufacturers have to adhere to specific regulations such as EPA. This ensures their motorcycles are environmentally friendly by reducing noise pollution and other emissions.
However, after getting the bike, most bike enthusiasts perform different upgrades to enhance performance and looks. The most common performance upgrades include installing performance exhausts, high-performance air intake, and fuel management systems.
The modifications come in different installation difficulty stages. Some modifications are easy, and you can handle them by using common tools and instructions. Others may require you to get a professional to handle them.
If you change the exhaust system, you change the engine’s amount of back pressure, affecting the air to fuel ratio that ensures complete combustion. When you upgrade the exhaust with slip-ons, the muffler section where the engine’s pressure is generated is most affected. Thus, it is essential to ensure your engine is well-tuned.
Most modern bikes come with O2 sensors, and they don’t need a fuel management system, and the bike will make the adjustments itself.
Additionally, most manufacturers tune their bikes to run very lean. This causes your bike to become hotter and also loses power. The extra heat is bad news on your thighs. It also puts the engine’s gaskets under stress, deforms parts, and scorches oil.
When you modify the bike, you enhance power and performance. However, you need other alterations to go along with the enhanced performance.
Therefore, you need proper tuning to ensure your Harley Davidson bike is pumping out the maximum amount of power.
Note, the best fuel management system for Harley Davidson come in different prices and installation difficulties. Your choice of system should depend on your bike and riding style.

Which is the best gas for a motorcycle?
Maybe you have noticed the various hoses and buttons for dispensing fuel at your local petrol/gas station. Is there a difference if you use one variety and not the other? And which is the best option for your motorcycle?
Every motorcycle with internal combustion requires gasoline to produce power and move the bike. Most manufacturers ensure that their bikes can run on multiple varieties and blends of fuel.
The difference in gasoline options has to do with the Octane number. Octane number refers to the ability of the fuel to get ignited when compressed or under pressure. The higher the octane number, the higher the tolerance of the gasoline while under pressure or compressed.
The best gas for your motorcycle should be high octane gasoline with at least a 91 rating. The gas should also be ethanol-free.
Can gas go bad in a motorcycle?
The gas that you use in your motorcycle is refined and is different from what is underground. The refined gasoline has a shelf life. If you don’t use your motorcycle a lot or plan to store it for an extended period, it’s essential that you find out how long the gas will last before becoming bad.
If you use unstabilized gas on your motorcycle, it can start going bad after 30 days, especially if you are not using your bike?
For stabilized gas, you should not use it if it has been lying on the motorcycle for 6-12 months.
Gasoline gas goes bad after exposure to oxygen, which starts to change its chemistry. The chemical change can start happening after 30 days and will continue over time. If the gas goes bad and you use it on your motorcycle, you may experience a host of mechanical problems on the road.
To prevent the gas from going bad, ensure you use it or top it up with fresh gas after some time.
Should I use ethanol-free gas in my Harley Davidson bike?
Harley Davidson recommends the use of unleaded gasoline in your engine for the best experience and performance.
Gasoline without ethanol offers the best efficiency and performance for engines with internal combustion.
Can I run race oil on my Harley Davidson bike?
