Engine vibration was always an issue, at first forcing users to hang their remote float bowls from flexible rubber elements and then, in the case of Gilera and MV Agusta, to also mount their carburetors with some decree of vibration isolation on short pieces of fuel-compatible rubber hose held in place by hose clips. Moto Guzzi, in its fabled 500cc V-8, tried at first to fuel all its eight interdigitated carburetors from two float bowls—one on the right, one on the left. This worked so badly (Pop! Bang! Kakkachooie!) that Guzzi itself (already making the carburetors) ultimately produced sets of eight tiny separate float bowls, one per carburetor.
