Frequently Asked Questions
A bleed pilot jet is a precision component in a Mikuni carburetor that controls the amount of air mixed with fuel in the pilot circuit. This affects idle quality and low-speed throttle response.
Signs include rough idle, poor low-speed throttle response, or inability to achieve proper idle adjustment. Replacement is often needed after carburetor cleaning or if the original is damaged.
Jet sizing is critical for proper carburetor function. Only use the size specified for your carburetor model. Incorrect sizing can cause running issues.
Typically yes, the carburetor must be removed and partially disassembled to access the bleed pilot jet. This is not a field-adjustable component.
Check your carburetor's documentation, the Mikuni website, or contact an authorized Mikuni dealer with your carburetor model number.
