Description
Proper jetting is fundamental to carburetor performance—too lean and you risk engine damage, too rich and you sacrifice efficiency and throttle response. The S&S Cycle Main Jet .120″ delivers the precise fuel metering your engine needs to run cleanly across the RPM band, whether you’re tuning a stock cruiser or dialing in a performance build. This five-pack ensures you have spares on hand for testing different air-fuel ratios without interrupting your ride.
Main jets control fuel delivery at steady-state throttle positions, making them critical for mid-range performance and fuel economy. A .120″ orifice sits in the sweet spot for most stock and mildly modified engines, providing the baseline jetting many builders start with before fine-tuning to their specific setup.
