The 50 DCO SPW is a unified carburettor - meaning that the spindle now passes through the entire body. There is threaded shaft on both sides of the carburettor. The DCO series carburettor is designed for all out performance with excellent tunability. There is no cold start mechanism (as fitted to DCOE carburettors) therefore minimising moving parts and the chance of any fuel accidently leaking into the carburettor. Factory Calibrations are; 46mm chokes, 5.0 aux venturi, F7 emulsion tube, 180 main jet, 160 air corrector, 65F8 idle jet, 45 pump jet, 100 pump spill, 250 needle valve The air horns are 45mm in length
