Set up the gauge, cut the rubber hoses in two pieces, and connect the hoses with white plastic valves, attach the rubber hoses with the gauge. 3. Remove the vacuum attachment plug-screws from the carburetor flanges or intake manifolds and install the brass adapters in these holes ( long adapters to inside carbs and short adapters to the outside carbs). 4. Multi-cylinder engines require synchronous opening of the throttle valve. 5. Through synchronisation, the same vacuum is reached before the carburettors. A dial is required for each carburettor for synchronisation. Adjustment of the individual compressors is done via the adjustment mechanisms. You need to start the engine and check the gauges, adjust the dial and the screw slightly, stall the motorcycle, give the throttle a few snap backs, and repeat the process until the designer result is achieved.
