About This Product
This Mikuni HSR main jet, size #157.5, is designed for use in Mikuni HSR42, HSR45, and HSR48 performance carburetors. These carburetors are a popular choice for Harley-Davidson riders seeking better throttle response and increased torque. The main jet is the primary fuel metering component for the upper throttle range, and this specific size allows for precise calibration of the air-fuel ratio. Manufactured from high-grade brass to exacting standards, Mikuni jets offer the reliability and flow consistency needed for professional-grade tuning. By using genuine Mikuni parts, you ensure that your carburetor operates as intended, providing the necessary fuel for both stock and highly modified V-Twin engines during high-demand riding situations.
