Lectron Fuel Systems took years of rider feedback on their wildly popular 38mm H-Series Carburetors to develop the original Billetron 38mm 2-Stroke Carburetor. The Billetron Pro 38mm Carburetor takes the original Billetron a step further and obliterates what was previously thought possible for two-stroke performance. Designed for maximum adjustability, instant hit, and a huge increase in low end throttle power, the Billetron Pro allows you to achieve your bike’s perfect fuel delivery, trackside, in a fraction of the time. The patent pending Xcelerator metering rod gives a significant boost in low RPM torque (up to 20%) and rideability over the previous metering rod. Three easily adjustable fuel circuits, metering rod, power jet, and toque jet (Pro-Series only), give the rider complete control over when and where fuel is needed to unlock new levels of performance. The optional TPS upgrade allows 3D mapping with OEM and aftermarket CDIs as well as oil injection functionality on models with these features (Yamaha/Beta).
