More Power. Perfect Balance. No Jetting.

The Lectron PRO-SERIES 32mm carburetor system is the ultimate upgrade for twin-cylinder 2-stroke riders tired of syncing carbs, chasing jetting, and dealing with inconsistent fueling between cylinders. Built on our proven PRO-SERIES platform, it delivers crisp throttle response, stronger low-end pull, and clean, balanced fueling across both cylinders—without jets to swap or clog.

Featuring dual 32mm high-velocity bores and our new Xcelerator™ metering rods, this system delivers instant, equalized fuel the moment you crack the throttle. The result? Zero bog, no hesitation, and smooth, hard-hitting acceleration with perfectly matched cylinder performance.

The Torque Jet has been relocated to the engine side of each carburetor, allowing for quick, on-the-fly idle adjustments—no tools needed. Combined with integrated Power Jets and Lectron’s adaptive metering system, each cylinder automatically compensates for changes in elevation, temperature, and riding conditions—keeping both sides perfectly in sync and your air/fuel ratio consistently dialed.

Each kit includes everything needed for a clean, straightforward install—matched carburetors and throttle cables—so you can spend less time syncing and tuning, and more time riding.

Who It’s For:

Designed for twin-cylinder 2-stroke riders who demand smooth, consistent performance from both cylinders. Whether you're riding vintage performance bikes, twins in flat track, or custom builds, this setup eliminates common issues like uneven fueling, plug fouling, blubbering, and constant rejetting. The result is a smoother, more controllable powerband, improved 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.

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.

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.

FAQ

What does the Xcelerator metering rod do?

The Xcelerator metering rod stores fuel in an internal reservoir and delivers it instantly during rapid throttle openings, eliminating the hesitation caused by vacuum drop during
throttle transitions.

Do Lectron carburetors adjust for altitude automatically?

Yes. Because the metering rod’s fuel delivery is driven by the pressure differential between the float bowl and the venturi, it automatically scales with changes in air density. At higher elevations, reduced air density lowers the pressure differential, which reduces fuel flow proportionally. This passive compensation eliminates the need for re-jetting when riding across different elevations.

How does a metering rod carburetor work?

A metering rod carburetor uses a single tapered rod positioned within the fuel bore to meter fuel continuously based on airflow. As the throttle slide lifts, the rod’s taper increases the effective flow area, and the pressure differential created by airflow through the venturi draws fuel proportionally. This replaces the multiple fixed jets found in traditional carburetors with one continuous fuel curve.

What is the biggest difference riders notice?

Most riders notice improved throttle response, smoother power delivery, and consistent performance across varying conditions.
