Lectron PRO-2 Carburetor Kit for RG/RZ/RD500 & TZ750 | Responsive, Precise + Performance

More Power. Perfect Sync. No Jetting. The Lectron PRO-SERIES 32mm carburetor system is the ultimate upgrade for 4-cylinder 2-stroke riders tired of syncing four carbs, chasing jetting, and dealing with inconsistent fueling across cylinders. Built on our proven PRO-SERIES platform, it delivers razor-sharp throttle response, stronger low-end pull, and clean, perfectly balanced fueling across all four cylinders—without jets to swap or clog. Featuring quad 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 a smooth, high-revving surge of power with all four cylinders firing in perfect harmony. 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 all four perfectly synchronized 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 eliminate the hassle of syncing and spend more time riding. Who It’s For: Designed for 4-cylinder 2-stroke riders who demand precise, consistent performance across every cylinder. Whether you're running vintage race machines, high-performance builds, or unique multi-cylinder projects, this setup eliminates common issues like uneven fueling, plug fouling, blubbering, and constant rejetting. The result is a broader, more controllable powerband, lightning-fast throttle response, and a cleaner-running engine from idle to peak RPM.
