Fuel Systems & Carburetors
Motorcycle Fuel Systems & Carburetors
The fuel system is responsible for delivering the precise mixture of fuel and air that your engine needs to produce power cleanly, reliably, and efficiently across every throttle position and every operating condition. When it works correctly you never think about it. When something goes wrong, you feel it immediately in the way the engine starts, idles, responds to throttle input, and performs under load. A carburetor that is worn, dirty, or incorrectly jetted for the current conditions produces flat spots, hesitation, rich or lean running, and starting difficulty that makes every ride more frustrating than it needs to be. A fuel pump that is failing delivers inconsistent fuel pressure that causes surging and power loss that no amount of jetting or tuning can compensate for. Getting the fuel system right is foundational to everything else the engine does.
Mad Lads Moto stocks a comprehensive range of fuel system components for carbureted and fuel-injected motorcycles across dirt bike, motocross, enduro, trail, street, dual sport, and adventure applications. Whether you are rebuilding a worn carburetor on a two-stroke motocross bike, replacing a failing fuel pump on a fuel-injected adventure tourer, upgrading to a performance throttle body for more airflow on a modified engine, or simply replacing a cracked fuel line before it becomes a fuel leak and a fire risk, we have what you need. Here is how we have organized this section to make finding the right component straightforward:
- Carburetors & Jets - Complete replacement carburetors, carburetor rebuild kits, main jets, pilot jets, needle jets, and jet kits for altitude and temperature tuning on carbureted two-stroke and four-stroke motorcycles.
- Tanks & Fuel Pumps - Replacement fuel tanks, auxiliary fuel tanks, fuel pumps, and fuel pump components for machines where tank damage, tank capacity limitations, or fuel delivery failures require attention.
- Injectors, Throttle Bodies & EFI - Fuel injectors, throttle body assemblies, fuel pressure regulators, and electronic fuel injection components for fuel-injected motorcycles where precise fuel delivery requires specific component maintenance and replacement.
One of the most common and most avoidable fuel system problems across all motorcycle types is fuel system damage from ethanol-blended gasoline that has been left to sit in the tank and carburetor during storage. Modern pump gasoline containing ethanol absorbs moisture from the atmosphere over time and the resulting water-ethanol mixture settles to the bottom of the fuel system where it attacks rubber fuel lines, dissolves carburetor diaphragms, corrodes aluminum carburetor components, and leaves a varnish residue in jets and passages that causes starting and running problems when the machine comes back into service. Using a quality fuel stabilizer, draining the float bowl at the end of every storage period, and considering ethanol-free fuel for machines that sit for extended periods are the most effective ways to prevent fuel system damage that is expensive to repair and entirely avoidable with basic preventive care. We stock fuel system components for Honda, Yamaha, Kawasaki, Suzuki, KTM, Husqvarna, Beta, GasGas, and more. Use our year, make, and model fitment tool to confirm fitment before you order.
