You feel it every time you mash the throttle on a long straightaway. That little voice in your head that says, “I wish this thing had a bit more punch.” We’ve all been there. You love your quad, but you’re craving that extra edge to pull away from your buddies or conquer that steep hill climb with more authority.
You’re in the right place. We’re about to break down exactly how to make an ATV faster, from simple weekend projects to more serious performance upgrades. This isn’t about reckless speed; it’s about unlocking the full potential of your machine safely and intelligently.
This comprehensive how to make an ATV faster guide will walk you through the essential steps, explaining the benefits and what to expect at each stage. Let’s get those wrenches turning and find some hidden horsepower.
Before You Mod: The Foundation of Speed is Maintenance
Hold on there, speed demon. Before you start bolting on shiny new parts, we need to talk about the single most important factor in your ATV’s performance: its current state of health. A poorly maintained quad will never be a fast quad, no matter how much money you throw at it.
Think of this as your pre-flight checklist. A well-oiled machine is a fast machine. This is one of the most crucial how to make an ATV faster tips we can give you.
The Essential Tune-Up Checklist
- Clean Your Air Filter: A clogged air filter is like trying to breathe through a straw. It suffocates your engine and robs it of power. Clean or replace it according to your owner’s manual.
- Change the Oil and Filter: Fresh oil is the lifeblood of your engine. It lubricates, cools, and cleans. Old, broken-down oil increases friction and heat, which are enemies of horsepower.
- Check Your Spark Plug: A fouled or worn-out spark plug creates a weak spark, leading to incomplete combustion and lost power. A new plug is cheap insurance for a strong-running motor.
- Tire Pressure: This is a free performance mod! Over-inflated or under-inflated tires can drastically affect handling and straight-line speed. Check your pressures before every ride and set them for the terrain you’ll be on.
Step 1: Let It Breathe – Uncorking Airflow for Instant Gains
Engines are essentially big air pumps. The more air they can move in and out, the more power they can make. The easiest and most affordable way to start your journey is by improving the “inhale” side of the equation.
Your stock intake system is designed to be quiet and meet emissions standards, which often means it’s restrictive. We can fix that.
Upgrade to a High-Flow Air Filter
This is often the very first mod people make. Replacing your stock paper or foam filter with a performance aftermarket filter from a brand like K&N or Twin Air can make a noticeable difference.
These filters use less restrictive materials, allowing more air into the engine. The benefits of how to make an ATV faster with this mod are improved throttle response and a small but real horsepower bump. Plus, they are reusable, making them an eco-friendly choice in the long run.
Consider an Airbox Lid or Full Intake System
For even more airflow, you can modify or replace your airbox. Some riders remove the restrictive airbox lid entirely (best for dry conditions) or install a vented aftermarket lid. A full intake system replaces the entire tube from the filter to the throttle body, creating a smoother, more direct path for air.
Step 2: The Exhale – Upgrading Your Exhaust System
Now that we’ve improved the air going in, we need to help the engine push the exhaust gases out more efficiently. Your stock exhaust is heavy, restrictive, and designed to be whisper quiet.
An aftermarket exhaust is one of the most popular mods because it provides gains in power, a significant reduction in weight, and a much more aggressive sound.
Slip-On vs. Full System
- Slip-On Exhaust: This replaces only the muffler (the rearmost part of the exhaust). It’s easier to install and more affordable. You’ll get a better sound and a modest power gain.
- Full System: This replaces everything from the engine cylinder head back, including the header pipe and the muffler. It’s more expensive and complex to install but offers the greatest performance gains by optimizing the entire exhaust flow.
A common problem with how to make an ATV faster using an exhaust is that it can cause the engine to run lean (too much air, not enough fuel). This brings us to our next critical step.
Step 3: Fueling the Fire – Optimizing Your Fuel Delivery
You’ve added more air with a new intake and exhaust. Now, your engine is thirsty for more fuel to match. Failing to adjust your fuel delivery is a rookie mistake that can lead to poor performance and even engine damage.
This is where how to make an ATV faster best practices really come into play. A well-tuned engine is not only powerful but also more efficient, making this a more sustainable way to get performance.
For Fuel-Injected (EFI) ATVs: The Fuel Controller
If your ATV is modern and has Electronic Fuel Injection, you’ll need a fuel controller or “tuner.” This device, like a DynoJet Power Commander or Vance & Hines FP3, plugs into your wiring harness and allows you to adjust the air/fuel ratio.
Most tuners come with pre-loaded “maps” for common intake and exhaust combinations, making it a simple plug-and-play affair. For ultimate performance, you can get a custom dyno tune from a professional shop.
For Carbureted ATVs: Re-Jetting the Carb
If you’re riding an older machine with a carburetor, you’ll need to “re-jet.” This involves physically swapping out the small brass jets inside the carburetor bowl for larger ones that allow more fuel to flow. Jet kits are available for most models and are a must-do after intake/exhaust mods.
How to Make an ATV Faster: Advanced Drivetrain and Gearing Mods
So far, we’ve focused on making more power. But what about how that power gets to the ground? The drivetrain is where you can fine-tune your ATV’s performance for specific types of riding, whether it’s quick acceleration or higher top speed.
Install a Performance Clutch Kit
Your ATV’s CVT (Continuously Variable Transmission) uses a clutch system to transfer power. An aftermarket clutch kit can make a huge difference in how your quad feels. These kits typically include different springs and weights that change how and when the clutch engages.
You can tune your clutch for faster, more aggressive engagement off the line (great for drag racing or mud bogging) or for smoother engagement for technical trail riding. This mod doesn’t add horsepower, but it makes much better use of the power you already have.
Change Your Sprocket Gearing
For sport ATVs with a chain and sprockets, changing your gearing is a classic speed-tuning trick.
- Smaller Front Sprocket / Larger Rear Sprocket: This is called “gearing down.” It will increase acceleration and low-end torque but will reduce your top speed. It’s perfect for tight trails and quick sprints.
- Larger Front Sprocket / Smaller Rear Sprocket: This is “gearing up.” It will sacrifice some acceleration but will give you a higher overall top speed. This is ideal for open desert riding or fire roads.
Weight Reduction and Tires: The Unsung Heroes of Speed
Horsepower is only half the battle. The power-to-weight ratio is what truly matters. Every pound you can remove from your ATV is like getting free horsepower. It’s a simple concept that many people overlook.
Start with the easy stuff. Remove any unnecessary racks, cosmetic plastics, or heavy accessories you don’t use. For the more dedicated, switching to lighter aftermarket parts like A-arms, wheels, and axles can shave off significant weight.
Your tires are also critical. Heavy, aggressive mud tires will be much slower on a hard-packed trail than a lighter, all-terrain radial. Choose the right tire for your primary riding style to maximize performance.
Frequently Asked Questions on How to Make an ATV Faster
How much faster can I make my ATV?
This depends entirely on your machine, your budget, and how far you’re willing to go. Simple bolt-ons (intake, exhaust, tuner) can often add 5-10 MPH to your top speed and noticeably improve acceleration. More advanced engine and drivetrain work can yield much more significant results.
What is the cheapest way to make my ATV faster?
The cheapest ways are free! Start with a full maintenance tune-up and ensure your tire pressures are correct. After that, a high-flow air filter is the most affordable first performance part you can buy.
Will these mods make my ATV less reliable?
Not if done correctly. Using quality parts and, most importantly, ensuring your air/fuel ratio is correct with a tuner or proper jetting will maintain or even improve reliability. A common problem is when people add parts without proper tuning, which can cause the engine to run hot and lean, leading to long-term damage.
Do I need to be a mechanic to do these upgrades?
Most of the mods discussed here—air filter, slip-on exhaust, and a plug-in fuel controller—can be done by a careful DIYer with a basic set of tools. Internal engine work or a full exhaust installation might be best left to a professional if you’re not comfortable with it.
This how to make an ATV faster care guide is all about making smart, incremental improvements. Start with the basics, see how it feels, and build from there. The journey of modifying your machine is half the fun.
By following these steps, you’re not just chasing speed; you’re learning the ins and outs of your machine and tailoring it to your exact needs. Now, get out in the garage, get to work, and get ready to feel the difference on the trail. Ride fast and ride safe!
