If your engine runs too lean (hesitation, popping on decel) go larger. If too rich (black spark plug, fouling) go smaller. Consult your carburetor tuning guide.
No. Verify your carburetor model accepts FN-series jets. Different Mikuni models use different jet styles (VM, TM, Roundslide, etc.).
Possibly. Modifications that increase airflow may require rejetting for optimal performance. Consult tuning guides for your specific setup.
