Lectrons Llc Billetron Hdx / Hdx+ Throttle Cable 51"

Torque. Control. Simplicity. The BILLETRON HD-X Series is purpose-built for Harley Davidson and similar large-displacement engines, delivering strong low-end torque, clean throttle response, and minimal tuning. The HD-X supports up to 96ci engines, while the HD-X+ is optimized for high-output builds up to 124ci with a custom larger bore for increased airflow. With three precision fuel circuits — the externally adjustable Idle Fuel Control, Xcelerator™ Metering Rod, and Power Pet — this carburetor gives you total control over fuel delivery while remaining incredibly easy to set up and ride.
