Sudco Low Speed Jet for Keihin Carburetors

The Sudco Low Speed Jet for Keihin carburetors, also called a slow jet or pilot jet, meters fuel in the idle and off-idle part of the throttle range. It lets you fine-tune carburetor performance in that range. Sudco is a long-time supplier of carburetors, jetting and rebuild components for Keihin and Mikuni carburetors.

Key Features:

• Designed for Keihin carburetors, including PJ, PWK and PWM series and some smooth-bore designs
• Controls fuel delivery at idle and from off-idle to roughly 1/4 throttle, where the slow jet has the most effect
• Available in multiple jet sizes so you can richen or lean the low-speed mixture to suit engine modifications, exhaust changes, altitude or temperature
• Works as a replacement part when rebuilding or re-jetting a carburetor

A larger slow jet richens the mixture in the low-speed range, and a smaller one leans it. Keihin and Mikuni jetting components are not interchangeable, so use this jet only in Keihin carburetors. Pick the size that matches your carburetor's jetting requirements.
