Hello. I own a 1986 Kawasaki GPZ600. I have 4 carbs on it, And im having a bit of hosing problems. The two center carbs (2 & 3) have a T hose connected to it, which connects to the gas tank. And the outer carbs (1 & 4) are connected together by a hose. But how do these carbs get their gas, or do they even get gas? Is this setup wrong?
