The connection under the motorcycle carburettor is for the oil pipe. There are two interfaces on the carburetor of the motorcycle engine, the upper is cast in one piece with the carburettor. It is also an air balance pipe, a tube that keeps the internal pressure of the carburettor balanced with the external atmospheric pressure. The next copper pipe connection is the fuel line that represents the channel to feed the fuel in the fuel tank into the carburettor.
