Flat Slide Carburetors have advantages over round slide carburetors in airflow and fuel signal. The improved fuel signal allows better and more precise fuel metering for better performance and consistency.
EC dials in the fuel calibration to optimize air-fuel ratios for maximum power and acceleration. The carburetors are blueprinted within the tuning range for changes due to variations in atmospheric conditions.
The carburetor flows 126 cfm @ 28-Inches, providing sufficient flow for almost all modified cast heads and stock or mildly modified billet heads.
EC uses their billet velocity stack to improve the carburetor's inlet airflow.
We recommended using the flat slides mostly on straight-line drag racing machines or mini bikes that lean when turning. The flat slide is also a good choice for karting or 4-wheel racing machines but may benefit from a diaphragm carburetor like our XR Intimidators. If you are unsure if this carburetor fits your application, call before ordering.
The carburetor is tuned for gas at less than 1800 feet above sea level. Anything more will require additional tuning.
Do not use a stock exhaust or weenie pipe header for the best performance.
