Frequently Asked Questions
The low speed (pilot) jet controls fuel metering at idle and low RPM operation. It affects idle quality, throttle response off-idle, and low-speed running characteristics.
Consult your vehicle's service manual or carburetor documentation. Jet selection depends on altitude, temperature, and engine modifications. Start with OEM specification and adjust if needed.
While possible, it's recommended to clean the carburetor when replacing jets to ensure proper fuel flow and atomization.
Larger numbers = larger orifice = richer fuel mixture. Smaller numbers = leaner mixture. Differences of 2.5 units create noticeable changes in running characteristics.
The FN100606 prefix indicates this is a genuine Mikuni component. Verify part number matches your carburetor model before purchasing.
