High quality alloy trumpet with fixed gauze.
Will fit Dell’orto PHM carburettors with a 52mm intake thread.
These were copied incorrectly from a sample – the internal diameter at carb end is 36mm and will obscure small intake holes of PHM carburettor and may effect carburettor performance if not modified.
The gauze is approximately 18mm in addition to the trumpet length.
Diameter at gauze end 75mm
