Frequently Asked Questions
The low speed (pilot) jet controls fuel flow at idle and low throttle positions. It affects idle quality, throttle response, and low-RPM running characteristics.
If your bike runs rich (black smoke, fouled plugs) at idle, try a leaner jet (lower number). If it runs lean (hesitation, popping), try a richer jet (higher number). The 145 size is a common middle-ground specification.
No. Different Mikuni carburetors (VM, TMX, TM, etc.) have different jet configurations. Verify your carburetor model and jet compatibility before purchasing.
Yes. Higher altitude or cooler temperatures may require leaner jetting. Warmer temperatures or lower altitude may require richer jetting. The low speed jet affects idle and low-speed running.
Low speed (pilot) jets control fuel at idle and low throttle. High speed (main) jets control fuel at higher RPMs and full throttle. Both work together for proper carburetor tuning.
