SJ147.5-4 Mikuni HSR main jet N102-221, size 147.5

Getting the fuel mixture just right is the key to unlocking performance, and these EBC main jets are built for that exact purpose. Manufactured by A-BAX Precision Engineering, this size 147.5 jet is a direct replacement for the Mikuni N102-221 series. It fits a wide range of carburetors, including the HS40 and the HSR42, HSR45, and HSR48 performance series. These jets are also suitable for BSR, SV650, and BN series carbs like the BN38, BN44, and BN46I. Sold as a pack of four, they ensure you have the parts on hand to dial in your high-speed fuel circuit accurately. These precision-engineered jets provide the consistent flow rates necessary for a smooth, powerful engine response across the entire RPM range.
