Mikuni Genuine VM32 carb will do wonders for most bikes using 28-32mm carbs as a replacement or upgrade. The smooth action is welcome with a response that is needed.
40mm Spigot OD Intake
58mm Air Intake Bell OD EMGO or K&N air filters work well.
Works well with a gravity fed system with simple fuel shut off with NO vaccum petcock needed. Maybe useed on motorcycles and scooters, go carts and ATVs with great results.
Please idle adjustment screw side, pick the one you can get too so you can adjust carb which has idle and air and fuel adjustment. This will also place choke lever side.
