Hey there, fellow motorcycle enthusiasts! If you're looking to soup up your Harley-Davidson Sportster, you've probably stumbled upon the Arlen Ness air cleaner – a popular choice for riders who want both performance gains and a killer look. In this article, we'll dive deep into everything you need to know about these awesome air cleaners, covering their benefits, installation, and why they're a top pick for Sportster owners. So, buckle up, because we're about to explore the world of Arlen Ness and how their air cleaners can transform your ride!

Why Choose an Arlen Ness Air Cleaner for Your Sportster?

Alright, let's get down to brass tacks: why should you even consider swapping out your stock air cleaner for an Arlen Ness air cleaner? The answer lies in a combination of factors, starting with enhanced performance. The stock air cleaner on a Sportster is often restrictive, limiting the amount of air that can flow into the engine. Arlen Ness air cleaners, on the other hand, are designed with high-flow filters and optimized intake systems that allow your engine to breathe easier. This means more air, more fuel, and ultimately, more power. You might notice a snappier throttle response, improved acceleration, and a slight bump in horsepower and torque. It's like giving your Sportster a shot of adrenaline!

Beyond performance, Arlen Ness air cleaners are all about style. These things are designed to make a statement. Arlen Ness offers a wide variety of designs, from the sleek and modern to the classic and aggressive, so you can find one that perfectly complements your bike's aesthetic. Whether you're going for a subtle upgrade or a full-blown custom look, an Arlen Ness air cleaner can significantly enhance the visual appeal of your Sportster. And let's be honest, who doesn't love a bike that turns heads? The build quality is also top-notch, with many air cleaners featuring durable materials and finishes that are built to last. You're not just buying a performance part; you're investing in a piece of art that will endure for years to come.

But that's not all, guys! Arlen Ness air cleaners often feature washable and reusable filters. This is a massive win for maintenance and cost savings. Instead of constantly buying replacement filters, you can simply clean your Arlen Ness filter with a filter cleaning kit, and it's good to go. This eco-friendly approach also saves you money in the long run. The ease of maintenance is another perk. Most Arlen Ness air cleaners are designed for relatively easy installation and servicing, meaning you can often perform the necessary tasks in your garage with basic tools. This empowers you to take control of your bike's upkeep and avoid costly trips to the mechanic. In summary, Arlen Ness air cleaners offer a trifecta of benefits: performance, style, and practicality. They are a worthwhile upgrade for any Sportster owner seeking to elevate their riding experience.

• Velocity Series: For those who crave maximum performance and a race-inspired look, the Velocity Series is the way to go. These air cleaners are designed with a focus on airflow optimization. They typically feature a large, open filter element and a velocity stack design that channels air directly into the engine. This combination results in a significant increase in horsepower and torque, making the Velocity Series ideal for riders who frequently hit the open road.

Installation Guide: Putting on Your Arlen Ness Air Cleaner

Alright, now for the part many of you are most curious about: how to install an Arlen Ness air cleaner on your Sportster. Don't worry, guys; it's generally a straightforward process that you can tackle in your garage with a basic set of tools. While the specific steps may vary slightly depending on the air cleaner model and your Sportster's year, the general process remains the same. Here's a step-by-step guide to get you started.

• Gather Your Tools: Before you start, gather the necessary tools. You'll typically need a set of metric and/or standard wrenches and Allen keys, a screwdriver, a torque wrench, and possibly a shop towel to protect your bike's paint. Make sure to have a clean workspace and good lighting to see what you're doing. It's always a good idea to have a torque wrench on hand to ensure you don't over-tighten any bolts, which could damage your bike. Depending on the specific air cleaner and your bike, you might need a few specialized tools, but the installation kits often include everything you need.
• Remove the Stock Air Cleaner: Begin by removing the stock air cleaner. This usually involves removing the cover, the filter, and then the backing plate. Consult your Sportster's service manual or a step-by-step guide specific to your bike model to make sure you're following the correct procedure. Disconnect any necessary hoses or sensors connected to the stock air cleaner. Take your time, and be careful not to damage any surrounding components.
• Install the New Backing Plate: Once the stock air cleaner is removed, install the new backing plate provided with your Arlen Ness kit. This backing plate is crucial for mounting the air cleaner. It's designed to align with the bolt pattern on your Sportster's engine. Ensure the backing plate is properly aligned and secured, tightening the bolts to the torque specifications provided in the instructions. It's important to use the correct torque to prevent leaks and ensure a secure fit. Make sure all the components fit smoothly and the new backing plate is flush with the engine.
• Attach the Filter and Cover: Next, attach the filter element to the backing plate. This usually involves simply sliding the filter over the mounting studs and securing it with the provided hardware. Then, install the cover, which often features the stylish Arlen Ness design. Ensure all the components fit snugly and are securely fastened. Before tightening everything down completely, double-check that the filter is properly seated and that there are no gaps or obstructions. Then secure the cover.
• Reattach Hoses and Sensors: Reconnect any hoses and sensors that you disconnected from the stock air cleaner. Ensure everything is properly connected and secured. This is a critical step to ensure your bike runs correctly. Double-check all connections to prevent any potential issues. Make sure nothing is pinched or damaged. Pay close attention to any wiring or vacuum lines that need to be reattached.
• Final Checks and Test Ride: Once everything is installed, give your bike a final once-over to ensure everything is secure and properly aligned. Check for any leaks and make sure all bolts are properly tightened. Start your engine and listen for any unusual sounds. Take your Sportster for a test ride, paying attention to the throttle response and any changes in performance. If everything feels good, you're all set!

If you're unsure about any step of the process, consult your Sportster's service manual or seek assistance from a qualified mechanic. Always prioritize safety and follow the manufacturer's instructions to ensure a successful and trouble-free installation. The whole process is usually not too difficult, and many riders find it to be a satisfying DIY project. Enjoy your new Arlen Ness air cleaner!

Maintenance and Care for Your Arlen Ness Air Cleaner

Alright, now that you've got your shiny new Arlen Ness air cleaner installed, let's talk about keeping it in tip-top shape. Regular maintenance will not only ensure your air cleaner performs at its best but will also extend its lifespan. Here's how to properly care for your Arlen Ness air cleaner.

• Cleaning Your Air Filter: One of the primary advantages of an Arlen Ness air cleaner is the ability to clean and reuse the air filter. The frequency of cleaning depends on your riding conditions. Riding in dusty or dirty environments will require more frequent cleaning than riding on clean, well-maintained roads. As a general rule, inspect your air filter every few thousand miles or whenever you notice a decrease in performance. To clean the filter, remove it from the air cleaner housing and follow the instructions provided with your cleaning kit. Typically, this involves spraying the filter with a cleaning solution, allowing it to soak, rinsing it with water, and then allowing it to air dry completely. Don't use compressed air, as this can damage the filter material.
• Oiling Your Air Filter: After cleaning and drying your air filter, it's essential to re-oil it. Most air filter cleaning kits include the correct oil, but you can also purchase it separately. Apply the oil evenly to the filter, allowing it to penetrate the filter material. Excess oil can restrict airflow, so be careful not to over-oil. Once the oil has soaked into the filter, wipe off any excess and allow it to sit for a few minutes before reinstalling it. Proper oiling helps trap dust and dirt, protecting your engine from damage. Use the type of oil specified for your filter to ensure optimal performance and longevity.
• Inspecting and Maintaining the Housing: In addition to the filter, inspect the air cleaner housing regularly for any signs of damage or wear. Check for cracks, dents, or loose hardware. If you find any damage, address it promptly to prevent it from affecting the performance of your air cleaner. Clean the housing with a mild soap and water solution as needed, and ensure that all fasteners are properly tightened. Ensure that the housing seals properly to prevent any unfiltered air from entering your engine.
• Checking for Leaks: Regularly inspect the connections and seals of your air cleaner to ensure there are no air leaks. A leak can allow unfiltered air to enter your engine, which can lead to reduced performance and potential engine damage. Check the backing plate, filter, and cover for proper fit and secure all fasteners as needed. If you notice any air leaks, address them immediately by tightening the fasteners or replacing any damaged components. Regular inspections and proper maintenance will keep your Arlen Ness air cleaner performing optimally and protect your investment for years to come.

By following these simple maintenance tips, you can keep your Arlen Ness air cleaner in top condition and enjoy years of reliable performance and stylish looks. Remember, regular care and attention will ensure your Sportster continues to run smoothly and look fantastic on the road.

Troubleshooting Common Issues

Even with the best maintenance, you might encounter some issues with your Arlen Ness air cleaner. Don't worry, guys; most problems are easily resolved. Here's a troubleshooting guide to help you tackle some common issues.

• Poor Engine Performance: If you notice a decrease in engine performance, such as sluggish acceleration or a lack of power, the air cleaner could be the culprit. Check the air filter for clogs or dirt buildup. If the filter is dirty, clean and re-oil it as described in the maintenance section. Also, ensure there are no air leaks around the air cleaner housing or connections. A leak can cause a lean air-fuel mixture, leading to poor performance. Inspect the seals and fasteners, and tighten them if necessary. If the issue persists, consult a qualified mechanic to diagnose and resolve any other potential engine problems.
• Air Leaks: Air leaks are a common source of problems. They can lead to a lean air-fuel mixture, causing poor performance and potential engine damage. Check for leaks around the backing plate, filter, and cover. Tighten any loose fasteners or replace damaged seals. You can also perform a visual inspection by checking the engine while it's running. Listen for any hissing sounds, which could indicate an air leak. If you can't find the source of the leak, it's best to consult a professional mechanic.
• Difficulty Starting: If your Sportster has difficulty starting, the air cleaner may be restricting airflow. Check the air filter for clogs or excessive oiling. A clogged or over-oiled filter can prevent enough air from reaching the engine, making it difficult to start. Clean or replace the filter as needed. Also, make sure that the air cleaner is properly installed and that all components are securely fastened. Verify all connections and hoses.
• Fuel Injection Issues: If your Sportster is fuel-injected, installing an aftermarket air cleaner may require adjustments to the fuel injection system. This is because the increased airflow can alter the air-fuel mixture. You may need to have your bike's ECU (Engine Control Unit) remapped or install a fuel management system to optimize the fuel delivery. Consult with a qualified technician to determine if your bike requires fuel injection adjustments. In most cases, a fuel management system or ECU remap will optimize the engine's performance.

If you're experiencing any of these issues, don't hesitate to seek professional help. A qualified mechanic can diagnose and resolve complex problems, ensuring your Sportster runs smoothly and reliably. Proper maintenance and troubleshooting will keep your ride running in top form for years.
