We’ve put together a list of the best motorized bicycle upgrades for your fuel system — from your gas tank to your fuel line. Whether you’re looking for a smoother ride, more power, or simply some parts that provide more convenience and will last you longer, we’ve got you covered with the best fuel components.
Why Add Fuel System Upgrades to Your Motorized Bike?
If you find your motorized bike is working just fine, you may be wondering why exactly you would want to upgrade it with some of these parts. But is “just fine” really satisfying you? The fact is you may not be getting the most out of your 2-stroke engine.
Upgrading your bike’s fuel system can really take your riding experience to the next level — and even provide extra safety. Here are a few benefits of upgrading your fuel components:
- Longevity — Your motorized bike’s stock parts are great for getting you up and running. As with any motorized vehicle, though, over time you’ll begin to see some wear-and-tear. High-quality fuel components will remedy that as they’re generally longer-lasting. That means less replacements over time.
- Smoother Riding — The right upgrades for your fuel system could give you a riding experience you didn’t even realize you were missing out on. Because your fuel system affects how your engine runs, the proper improvements will help you get a smoother, more comfortable ride.
- Increased Performance — A better running 2-stroke engine means more power and torque on the road. So if you want better speeds, an easier time climbing hills, and just overall better performance, you should consider giving your motorized bike a fuel system upgrade.
- Safety — The last thing you want is for your motorized bicycle engine to give out while you’re on the road. If your bike isn’t equipped with the best parts, you could potentially run into breakdowns, leaks, and other issues. Upgrading your stock parts can do a lot for your bike’s overall safety and reliability.
The Best Motorized Bike Fuel Components
Now that you know what the right motorized bicycle upgrades can bring to your fuel system, let’s take a look at some parts that’ll help you improve your engine. Here are the best motorized bike fuel components and what they have to offer.
Upgrade Your Gas Tank for Increased Fuel Capacity
When you’re really in the zone on the road or want to get where you’re going as quickly and seamlessly as possible, stopping to refill your gas tank can be a real inconvenience. And if you’re still riding with a stock tank, which can be pretty small, you probably have to refill it more often than you’d like to.
A larger gas tank for your motorized bicycle is the perfect upgrade to make your rides more convenient and keep you riding non-stop for longer. With a 3.5-liter gas tank, you won’t need to worry about refueling as often. 
In addition, if you want to avoid the hassle of mounting your tank on the frame of your motorized bike, a gas tank that can mount to your seat is a great fuel system upgrade. Seat-mounted gas tanks are versatile enough to attach to the seat tube of all sorts of motorized bikes, from road bikes to beach cruisers to fat tire bikes.

- 3.5 Liter Black Gas Tank (Our Price: $32.95)
- BBR Tuning 2L Seat Mounted Chrome Keg-Style Gas Tank (Our Price: $48.99)
Increase Your 2-Stroke Engine’s Power with the Right Carb Upgrade
Looking for better speed, power, and fuel efficiency? A high-performance carburetor is definitely the way to go. A carb upgrade offers a huge increase in airflow and fuel efficiency, ensuring that your motorized bike will be more powerful and faster.
Furthermore, a high-performance carburetor uses an automatic choke designed to release with the throttle input as your motorized bike’s engine has warmed up. That means you won’t need to adjust your carb at all.
You’ll notice the increase in acceleration and torque within minutes, so you can get going with no issues. Keep in mind, however, that high-performance carburetors are best when used in low elevations.
Alternatively, if you want better performance but aren’t looking to swap out your entire 2-stroke carburetor, a speed carburetor air filter is a great fuel system upgrade you may want to try. A good air-fuel ratio is essential to ensuring your motorized bike runs with power and ease. That’s why an air filter can make such a big difference.
An air filter upgrade will allow a larger intake of clean air to flow into your carburetor, meaning you’ll get extra power and a smoother ride — all without having to upgrade the carburetor itself. An air filter upgrade is also compatible with the stock NT Carb and Speed Carb, making it a great option regardless of your carburetor.
Recommended Motorized Bike Fuel Components:
- 66/80cc High Performance Carburetor (Our Price: $59.95)
- BBR Tuning Speed Carburetor Air Filter (Our Price: $24.95)
Avoid Gas Leaks with a Heavy Duty Fuel Valve and Fuel Line
A good seal between your fuel valve and your fuel tank is vital to preventing things like leaks and rust in your motorized bicycle engine. Your stock valve is pretty good, but there’s always room for improvement. As such, you should consider upgrading it with a well-crafted, heavy-duty fuel valve.
Heavy-duty fuel valves have tapered ends that are easily threaded into your tank to give you a perfect seal — no plumber’s tape or sealants necessary. These valves are easy to install, too. All you do is thread the valve into your tank’s gas port, install your fuel line over the brass barb, and turn on the fuel with the lever. Then you can have peace of mind knowing your engine will stay leak-free! 
Another component to consider upgrading to avoid gas leaks is your 2-stroke engine’s fuel line. Stock lines on motorized bicycles tend to crack after a long time in the sun, which leads to unfortunate leaks. A cheap fuel line is prone to damage and wear-and-tear, and it can put you at risk of breakdowns on the road.
If you’re still riding with a stock fuel line, it’s probably time to upgrade to something a little more durable.
A heavy-duty fuel line made of polyurethane is over 50 percent stronger than those fuel lines in your typical motorized bike engine kit. Plus, installation is simple, with no horse clamps required. A good heavy-duty fuel line is built to last for years, so you can ride confidently and safely for a long time without having to worry about pesky fuel leaks.

- AIGNEP Aluminum Heavy Duty Fuel Valve for 2-Stroke and 4-Stroke Bicycle Engines (Our Price: $19.95)
- Heavy Duty Fuel Line (Our Price: $5.95)
Keep Your Fuel System Clean with a Good Fuel Filter
Debris-clogged carburetor jets can be a real hassle, and they can cost you a great deal of time and energy spent on repairing your motor. A clogged carburetor means no gas in your engine, which means a motorized bike that doesn’t ride. That’s why you may want to consider upgrading to an improved fuel filter that’ll ensure rust and debris doesn’t get into your carb.
There are a few different options out there, but basically you’ll want to stick with something that’s sure to prevent particles from passing through. A mesh fuel filter, for example, will create a barrier that traps debris from getting into your motorized bike’s system.
Alternatively, a magnetic fuel filter works to catch all those little rust particles and metal shavings that come from your fuel tank or the fuel itself. The filter prevents these contaminants from clogging the small, susceptible jets of your carburetor. Magnetic fuel filters include a paper filter that will catch any pesky sediments and particles in your fuel.
Overall, a quality fuel filter will ensure your engine has top quality clean air and fuel while keeping your carburetor safe from clogging. It’s truly a game-changing fuel system upgrade for any motorized bike.

- Stainless Mesh 1/4 Performance Fuel Filter (Our Price: $9.95)
- Magnetic Inline Fuel Filter w/ Fuel Line (Our Price: $5.99)
