Ideal for DIY enthusiasts and mechanics working on intake systems, this jet installs in place of the compatible original element. For optimal adjustment, proceed with care: clean the seat, check the condition of the float chamber and circuits, and then make adjustments according to the recommendations of your carburetor or motorcycle manufacturer.
