FULL HIGHLIGHTS

Xcelerator Metering Rod

Instant Response. No Bog. All Throttle.

Designed to mimic an accelerator pump—without the complexity—the Xcelerator Metering Rod delivers fuel precisely when you need it. Whether you’re rolling it on or whacking it wide open, this circuit reacts instantly for throttle response you didn’t think a carb could deliver.

Air-Redirect Slide

Targeted Airflow. Sharper Response.

Engineered to channel low-throttle airflow directly at the metering rod, this slide enhances fuel signal where it matters most. Better signal means better response, especially in off-idle and low-RPM situations.

Power Jet (Top-End)

No Compromise. Top-End Control. No Tools Required.

Confidently dial in your low-end with the metering rod without top end compromise. The Power Jet circuit lets you adjust fuel delivery at high RPMs without disassembly and is independent of the metering rod—so you can confidently tune your bottom-end without sacrificing the top.

Precision Metering Rod = No Jetting

Set It. Forget It. Ride Hard.

Forget brass jets and constant tuning. Lectron’s metering rod tech automatically adjusts fuel delivery based on air demand, giving you perfect fueling from idle to redline—without the headache.
