Replacement intake rubber for the original Yamaha DT 50 carburetor. Connects the standard carburetor to the air filter box. Connection widths: 44mm/50mm . Length: 80 mmIn case of doubt, please compare the dimensions with old part beforehand! A defective suction rubber should be replaced immediately if it becomes porous or is already torn! Otherwise, the engine pulls false air over this point and the gasoline-air mixture is too low (piston eater danger!). .
