More Power. More Snap. No Jetting.

The Lectron PRO-SERIES 32mm carburetor is the ultimate upgrade for 2-stroke riders tired of spooge, bogging, and constant jetting changes. Built on our proven PRO-SERIES platform, it delivers crisp throttle response, stronger bottom-end pull, and clean, consistent fueling—without jets to swap or clog.

Featuring a 32mm high-velocity bore and our new Xcelerator™ metering rod, this carburetor delivers instant fuel the moment you crack the throttle. The result? Zero bog, no hesitation, and hard-hitting acceleration that brings your 2-stroke to life.

The Torque Jet has been relocated to the engine side of the carburetor, allowing for quick, on-the-fly idle adjustments—no tools needed. Paired with an integrated Power Jet and Lectron’s adaptive metering system, your bike automatically compensates for changes in elevation, temperature, and riding conditions, keeping your air/fuel ratio dialed at all times.

Each kit includes everything needed for a straightforward install—carburetor and throttle cable—so you can spend less time tuning and more time riding.

Who It’s For:

Designed for 2-stroke riders who want reliable, consistent performance in any condition. Whether you're ripping trails, lining up at the gate, or hitting technical singletrack, this setup eliminates common issues like blubbering, loading up, and constant rejetting. Ideal for small to mid-size 2-stroke platforms, delivering smoother power delivery, stronger throttle response, and a cleaner-running engine across the entire RPM range.

Chrome Plated Brass 'H' Slide

Throttle feel starts at the slide — and this one’s built to deliver. The chrome-plated brass ‘H’ slide adds durable mass for a more stable, weighted response, while the chrome finish drastically reduces friction to prevent sticking or galling under heat.

The result? A buttery-smooth throttle pull that stays consistent, even in the harshest conditions.

Don’t settle for flimsy or grabby. Feel the difference. Ride smoother.

Xcelerator Metering Rod

Provides a burst of fuel enrichment when ‘whacking’ the throttle for instant throttle response in all RPM’s. This innovation is a leap in metering rod technology by sustaining the hassle-free, no jetting benefits, while leveling up performance and throttle response. No compromise, just power made easy.

IFC: Idle Fuel Control

Unlike sealed-off idle circuits or carbs that require disassembly to make changes, our externally adjustable Idle Fuel Control gives you direct access to fine-tune low-RPM fuel delivery on the fly. Need to bump idle up after a cam swap or richen things for cold starts? A simple turn of the screw does it.

This isn’t a “set-it-and-pray” system — it’s precision control where it matters most.

Don’t settle for a carb that idles how it wants. Dial it in. Get control.

Billet Aluminum Construction

Our carburetors are CNC-machined from billet aluminum, delivering superior strength, precision, and durability. Billet aluminum starts with a solid block of aerospace-grade aluminum, each body is machined to exact tolerances, ensuring flawless accuracy and consistent quality that cast construction simply can’t match. Unlike cast carbs, billet aluminum provides enhanced reliability, long-term durability, and a premium finish that reflects its performance-driven design.

Built for riders who demand the very best, our billet carburetors combine long-term reliability with championship-level performance. This is more than just a carburetor—it’s a premium upgrade that reflects the highest standard of engineering and design.

FAQ

How does a Lectron carburetor work differently from a stock carb?

Lectron carburetors use a metering rod that adjusts fuel delivery based on real-time airflow, rather than fixed jets that require manual re-jetting as conditions change. The Lectron Technology section explains how this system works and why it produces more
consistent performance.

What is the best carburetor for a 2-stroke dirt bike?

The best carburetor delivers consistent fuel atomization, strong throttle response, and reliable performance across varying conditions. Design factors like fuel metering method, airflow velocity, and bore sizing matter more than brand alone. The Carburetor Buying Guides section covers these factors in detail.

Will a Lectron carburetor work at both low and high elevation?

Yes. Lectron’s metering rod system adjusts fuel delivery based on real-time airflow behavior, which means it compensates automatically for air density changes across elevations. Riders frequently travel between sea level and high-altitude riding locations without changing any carburetor settings.

What is the Xcelerator metering rod?

The Xcelerator is a patented metering rod design that includes an internal fuel reservoir and controlled orifices. It stores fuel near the venturi and releases it instantly during rapid throttle openings, solving the lean hesitation that occurs when engine vacuum drops faster than fuel delivery can respond. It functions as a mechanical accelerator pump built directly into the metering rod.
