The Street Demon has always been known for its innovative engineering, but the Shadow Black Edition takes that to another level. This all-new finish gives the carburetor a stealthy, ceramic-coated appearance to match today’s modern build styles while retaining all the proven performance features of the original. Expect stable idle, lightning-fast throttle response, and seamless performance across the RPM range. Its dual-pattern mounting base makes it compatible with most 4-barrel manifolds, and the patented Goggle Valve Secondary (GVS™) delivers power when you need it most. Inside, the aerospace-composite fuel bowl keeps fuel up to 20° cooler, while the one-piece main body eliminates potential leak paths. The Shadow Black ceramic coating not only looks sinister — it’s also heat- and chemical-resistant for long-lasting performance. Turn heads at the track, show, or cruise-in with the 750 Street Demon Shadow Black — where innovation meets attitude.
