Features:

1. Patent Pending Xcelerator Metering Rod: Our new, proprietary metering rod design brings previously unachievable levels of response. By adding the performance gains of an accelerator pump without the added complexity, the Xcelerator metering rod allows for instantaneous power at any RPM or throttle position. This seamless, instant throttle response inspires the confidence to push your bike to new limits.

2. High Precision Idle Fuel Bleed: This feature allows for maximum synchronization of fuel and air delivery at low throttle positions, ensuring optimal performance of any motorcycle under any conditions. Precise control over idle fuel delivery provides both high rideability and high performance.

3. Externally Adjustable Powerjet: A staple of our carburetor technology, the Powerjet allows you to adjust your top end fuel delivery to match different mods or riding styles with a turn of a screw! Precise control over top end fuel delivery maximizes the performance capability of your bike like never before.

4. Tailored Bore Design: Setting a new standard with its meticulously engineered bore design. Carefully crafted to maximize air flow and velocity dynamics to your engines capacity, this design caters to the specific volumetric capabilities of the engine. At every position, the carburetor optimizes air intake, translating into consistent and abundant power across the entire RPM range. This strategic design sets the stage for exceptional rideability and unbeatable power output.

5. Brass Chrome Throttle Slide: Our new, four-stroke centrically designed throttle slide provides unmatched levels of throttle modulation and consistency. The hard chrome and brass construction prevent wear and throttle friction which give a unmatched level of connection between the throttle and the rear wheel.

The BILLETRON HD-X represents the pinnacle of carburetor technology, where each feature has been meticulously engineered to provide ground breaking performance, adaptability, and rider control. It’s a harmonious integration of advancements that collectively elevate the riding experience to unbeatable heights.
