Frequently Asked Questions
The low speed (pilot) jet controls fuel mixture at idle and low throttle openings. It affects idle quality, throttle response, and low-RPM performance.
Signs you need jetting changes: poor idle, hesitation on acceleration, black smoke (too rich), or lean popping on deceleration. A 150 is a common mid-range size.
This jet fits Mikuni carburetors with the FN100606 jet seat. Verify your carburetor model and jet seat compatibility before purchasing.
Typically no - most low speed jets can be accessed without full carburetor removal, though you may need to drain fuel and remove the float bowl.
Higher numbers = richer mixture (more fuel). A 150 is richer than a 140, leaner than a 160. Adjust in small increments (5-10 sizes) based on performance.
