Licensed replica of the English Amal carburettor by the Spanish carburetor manufacturer Arreche. Cheaper and more robust than tuning carburetors or cheaper original spares. Different sizes for the corresponding tuning stages available: 16mm for original and 50cc tuning; 17.5mm for 70cc Sport Tuning; 19mm and 21 mm for racing and high end. Please select from the list below. Depending on the tuning-level, fine-tuning of the jetting / mixture is required. Fits on the original cylinder inlet. The compact design of the carburetor Arreche means the original air box can still be used.
