We’ll also be examining the advantages of having a Stage 2 air cleaner installed and provide some tips on how to get the most out of your new setup. So, let’s get started and get you that sweet performance upgrade you’ve been dreaming of!
Overview of Stage 2 Air Cleaners
For over a hundred years, Harley-Davidson bikes have been associated with the power, style, and iconic rumble of their engines. To further enhance the performance of these bikes, many Harley-Davidson riders turn to aftermarket upgrade. One of these upgrades is the Stage 2 Air Cleaner.
A Stage 2 Air Cleaner or a high-flow air cleaner is an aftermarket component designed to replace the stock air cleaner assembly on a Harley-Davidson bike. This upgrade is part of a multi-stage process aimed at improving the bike’s air intake and exhaust systems to maximize engine performance. Stage 2 Air Cleaners focus largely on enhancing the air intake side of the equation.
Here are some of the primary advantages of installing a Stage 2 Air Cleaner on a Harley-Davidson bike –
#1. An increase in torque and horsepower
One of the primary benefits of a Stage 2 Air Cleaner is the significant increase in torque and horsepower. Stock air cleaners on Harley-Davidson motorcycles are designed to meet emissions and noise regulations, often restricting the engine’s ability to breathe freely.
Stage 2 Air Cleaners, with their high-flow design, allow for a greater volume of clean air to enter the engine. This results in improved combustion, translating to more power and torque. Riders can feel a substantial boost in acceleration and overall performance, especially when overtaking or climbing steep inclines.
#2. Enhanced sound
Most Harley-Davidson riders love the distinctive rumble of their motorcycles. Installing a Stage 2 Air Cleaner can enhance this signature sound. The increased airflow and improved combustion can provide a deeper and more resonant exhaust note. Many riders find this enhancement in sound to be a desirable and rewarding aspect of the upgrade, further enhancing the auditory experience of their Harley-Davidson bikes.
#3. Noticeable increase in throttle response
A Stage 2 Air Cleaner enhances throttle response, making your Harley-Davidson bike more responsive to your inputs. When you twist the throttle, the engine reacts more promptly, delivering immediate power. This improved response is especially noticeable at low RPMs and during quick acceleration, which will give you better control over your bike and make city riding more agile.
#4. Burn fuel more efficiently
Surprisingly, a Stage 2 Air Cleaner can also provide improved fuel efficiency. When the engine receives a more optimal air-fuel mixture, it can burn fuel much more efficiently. This could result in better gas mileage, making your rides more economical in the long run.
#5. Part of other performance upgrade packages
A Stage 2 Air Cleaner is often a part of a broader performance upgrade package. When combined with a high-flow exhaust system and other components, it can result in significant benefits. These upgrades work together and create a well-balanced and optimized performance package for your Harley-Davidson bike.
#6. Personalize and customize your bike
Beyond performance benefits, Stage 2 Air Cleaners offer several customization options. Aftermarket air cleaner overs and designs come in different styles and finishes, allowing riders to express their individuality and match the bike’s aesthetics to their preferences. Whether you prefer a classic look or something unique, there are options to suit everyone’s taste.
Tools and equipment needed for installing a Stage 2 Air Cleaner
Upgrading your Harley-Davidson bike with a Stage 2 Air Cleaner is an exciting step toward improving its performance and unleashing its full potential. While the installation process is manageable, having the right set of tools on hand will be important for ensuring a smooth and successful upgrade. Here are the tools and equipment you’ll need to gather before you can start the installation process.
A set of quality screwdrivers is important for removing and securing various components during the installation process. Phillips and flat-head screwdrivers in different sizes will help you handle screws, clamps, and fasteners.
Pliers are versatile tools that can be used for gripping, bending, and holding parts in place. Needle-nose pliers are especially handy for reaching tight spots and securing hose clamps.
#3. Allen wrenches/hex keys
Harley-Davidson bikes typically use Allen or hex head screws and bolts. Having a set of Allen wrenches or hex keys in different sizes will ensure that you can easily loosen or tighten these fasteners.
#4. Socket set
A socket set is quite valuable when it comes to handling nuts and bolts with precision. Make sure that you have a wide range of socket sizes to accommodate various components on your motorcycle.
#5. Torque wrench
A torque wrench is important for ensuring that fasteners are tightened to the manufacturer’s specified torque settings. Proper torque will ensure that components are secure without risking damage from over-tightening.
#6. Soft-bristle brush or cleaning brush
Before installing a Stage 2 Air Cleaner, it is a great practice to clean the surrounding area to prevent any debris from entering the engine. A soft-bristle brush designed for air cleaner housing can help you remove dirt and dust effectively.
#7. Compressed air or air compressor
Compressed air or an air compressor is important for blowing away any remaining dust from the air cleaner housing and other components. It’ll help ensure a clean environment from the new air cleaner.
#8. Safety gear
You must prioritize your safety when working on your Harley-Davidson bike. Safety glasses and gloves will help protect your eyes and hands from dirt, debris, and any potential hazards.
#9. Replacement components
Depending on the specifics of your Stage 2 Air Cleaner kit and your bike, you may require replacement components like gaskets, O-rings, or hose clamps. Make sure that you have these parts ready if they aren’t included in the kit.
