Replacement pilot air screw assembly (x 4 sets) for Mikuni carburettors used on Triumph models. This screw is on the underside at the front of the carburettor. Original screws are stainless steel and suffer badly from seizing in the die cast alloy caburettor body. These replacement screws are now manufactured from electro plated brass, a much more appropriate material for this application.
Fits: 1200 Daytona, 1200 Trophy and 1000 Daytona.
