Unlike sealed-off idle circuits or carbs that require disassembly to make changes, our externally adjustable Idle Fuel Control gives you direct access to fine-tune low-RPM fuel delivery on the fly. Need to bump idle up after a cam swap or richen things for cold starts? A simple turn of the screw does it.
This isn’t a “set-it-and-pray” system — it’s precision control where it matters most.
Don’t settle for a carb that idles how it wants. Dial it in. Get control.
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.
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.
Chrome Plated Brass 'H' Slide
Throttle feel starts at the slide — and this one’s built to deliver. The chrome-plated brass ‘H’ slide adds durable mass for a more stable, weighted response, while the chrome finish drastically reduces friction to prevent sticking or galling under heat.
The result? A buttery-smooth throttle pull that stays consistent, even in the harshest conditions.
Don’t settle for flimsy or grabby. Feel the difference. Ride smoother.
