Frequently Asked Questions
If your engine runs too rich (black smoke, fouled plugs) at idle/low throttle, try a smaller jet. If it runs too lean (hesitation, popping), try a larger jet. The 117.5 is a common mid-range size.
This jet fits Mikuni carburetors that use FN-series jets. Verify your carburetor model number and consult Mikuni documentation or your vehicle's service manual to confirm compatibility.
Low-speed (pilot) jets control fuel at idle and low throttle openings. High-speed (main) jets control fuel at higher RPMs and throttle positions. Both may need adjustment for optimal performance.
On some applications, yes - if the jet is accessible from outside the carburetor bowl. However, full carburetor removal and cleaning is recommended for best results.
This is a fixed-size jet. You cannot adjust it like a needle valve. If you need different fuel flow, you must replace it with a different size jet.
