Unlock Maximum Performance with Alcohol Fuel

The Lectron PRO-SERIES Alcohol Carburetor is purpose-built for 125cc–500cc 2-stroke engines running methanol or alcohol fuels. Engineered to deliver the increased fuel volume alcohol requires, it provides razor-sharp throttle response, consistent fueling, and maximum horsepower while maintaining Lectron's signature externally adjustable metering system. Spend less time tuning and more time making passes or chasing podiums.

🏁 Who It's For:

Racers and performance enthusiasts running methanol or ethanol fuels who demand precise fuel delivery, instant throttle response, and race-proven reliability. Ideal for 125cc–500cc 2-stroke drag bikes, hill climb machines, speedway bikes, flat track racers, kart engines, and custom high-performance builds where alcohol fuel is the preferred choice.

Whether you're building a dedicated race engine or converting an existing setup to alcohol, the Lectron PRO-SERIES delivers the fuel flow, adjustability, and performance needed to get the most from your combination.

Tailored Bore Design

Unlike one-size-fits-most OEM carbs, our bore is precision-tailored to match your engine's air volume for sharper throttle response and better power delivery.

It's like a well fitted suit vs one from your dad's closet - mass applied sizing doesn't cut it.

Avoid the pitfalls of generic carbs. Get fitted.

Proven Performance

Our carburetors are built on well-established fuel delivery principles that have been tested across countless on and off-road applications. Whether you're racing, trail riding, or running a custom build, you can count on predictable throttle response, smooth power delivery, awesome peak power, and long-term reliability.

This is performance you can feel — without needing to overthink it.

Internal Fuel Circuits

Fully optimized internal fuel circuit routing, meaning the power jet and torque jet systems are fed through machined passages inside the carburetor body — not external hoses. These fuel passages have been designed to expedite fuel delivery by reducing the required vacuum necessary to pull fuel through each circuit and also shortens the fuel travel path which allows for near immediate fuel delivery. The result, a noticeably quicker throttle response and immediate power transfer to the ground.

By eliminating external fuel hoses, the PRO-SERIES not only looks cleaner but is also easier to install and less prone to hose-related damage in harsh riding conditions.

High Density Polyethylene (HDPE) Float Bowl

These HDPE float bowls are specifically engineered to withstand the harsh effects of methanol and other alcohol fuels. Unlike standard float bowls that can warp, soften, or melt when exposed to aggressive fuel blends, these maintain their shape and integrity even under demanding conditions. Whether you're running methanol other alcohol fuels, you can count on long-lasting durability, reliable performance, and the confidence that your float bowls are built to handle the job.

Modified Torque and Power Jet Circuits

Our Torque and Power Jet circuits are precision-modified to meet the increased fuel demands of methanol and other alcohol-fueled applications. By increasing the circuit diameter, these modifications deliver significantly greater fuel flow while maintaining the precise metering needed for consistent performance. The result is improved fuel delivery under high-load conditions, helping your carburetor keep up when maximum power is on the line.

Tailored Alcohol Metering Rod

Our specially designed alcohol metering rod is engineered to deliver the increased fuel volume required for methanol and other alcohol-fueled applications. Featuring a precision-machined groove along the tapered profile, it allows substantially more fuel flow than our standard or X-Celerator metering rods while maintaining accurate fuel metering. This optimized design ensures your carburetor can keep pace with the high fuel demands of alcohol fuels, providing consistent performance throughout the RPM range.
