Linear power. Zero hassle.
The BILLETRON Kart Carburetor Kit is built for racers who want crisp, predictable throttle response and simple tuning — with no jetting changes required. Designed for modern 2-stroke and 4-stroke kart engines, it delivers strong low-end torque, smooth midrange, and clean top-end power in a durable, billet-machined package.

Featuring a two-circuit fuel system with our Xcelerator metering rod and power jet, the BILLETRON offers consistent fueling and excellent throttle feel in tight turns and high-speed straights alike. An included throttle cable, fuel pump, and 12" of vacuum line make this a complete, race-ready kit.

🏁 Who It’s For:
Kart racers who want set-it-and-drive simplicity, responsive control, and clean, reliable performance — without the tuning complexity of traditional carbs or EFI.

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.

Power Jet System

Adds external adjustability of fuel for wide-open throttle positions. Fine tune your top end for increased power without sacrificing midrange - Ideal for racing and high-speed performance.

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.

Redirect Slide Ramp

Designed exclusively for our PRO-SERIES & BILLETRON carburetors, this unique slide design does more than control throttle - it redirects airflow to sharpen the fuel signal, delivering quicker, cleaner throttle response and more consistent power delivery across the rev range.

SafeDrain Overflow Bowl

SafeDrain is Lectron’s integrated overflow control system engineered to protect your engine from the complications of fuel overflow in the most demanding conditions. Whether you're navigating steep climbs, hammering through vibration-heavy terrain, or transporting a hot bike after a ride, SafeDrain gives excess fuel a clean exit path and enhanced geometry for improved sealing.

By combining overflow redirection with added venting for incline and decline situations, SafeDrain Bowl ensures stable fuel pressure and consistent performance where other systems fail. It’s peace of mind built into the bowl — no tuning, no fuss, just protection you can trust.

FAQ

Will the carb come pre-tuned?

We have over 50 years of experience with tuning carburetors. We setup each carb to a fundamentally determined setting based on information you provide to us. Your carb will be very close or spot on when received. With that said, varying factors like the bikes condition, wear, maintenance, oil ratio, and age of fuel can have an effect with tuning. We suggest a simple, slight tuning at install to achieve max performance and preferability. Once you set it, forget it. Enjoy no-hassle.

What if I need help with install or tuning?

No problem - we've got you covered. Our dedicated support team has extensive experience tuning and installing Lectron carburetors across a wide range of bikes and riding styles. Whether you're working through your initial setup or fine-tuning for specific conditions, we're here to help. Reach out anytime - we'll make sure your carb is dialed in and your bike runs like it should.
