Description

Turn up the performance on your street machine with the 750 CFM Street Demon®. Designed for engines that demand more airflow, this carburetor keeps the same user-friendly simplicity and iconic looks that made the original a favorite among enthusiasts. It’s calibrated to deliver rock-solid idle characteristics, instant throttle response, and unmatched smoothness at cruising speed. The dual-pattern mounting flange allows easy installation on both square and spread bore manifolds, and the integrated fuel bowl design prevents leaks while reducing heat soak. Its aerospace-composite fuel bowl keeps fuel up to 20°F cooler, helping to resist vapor lock on hot days. Finished in a durable shiny coating, this 750 Street Demon is the perfect blend of form, function, and street attitude.
