Fits Mikuni FVM28 and similar VM series flat-slide carbs on dirt bikes and ATVs.
#50 is a common stock or tuning size; check your bike's spec or use a jet kit for elevation changes.
If idle is lean (high RPM), go larger; rich (low RPM, fouling), go smaller. Consult a carb tuning chart.
No, reuse your existing O-ring or purchase separately if needed.
