Ok, I'll admit my schoolboy error.
I'm swapping my fzs600 2003 foxeye engine and all is going well until I fit the carbs. I have 2 small metal pipes, facing upward, situated on the front of the carbs. 1 between carbs 1&2 the other between 3&4. There is a small pipe outlet on the upper right hand side of the radiator which i am thinking should connect to the 2 on the carbs. I have no recollection if I took these pipes off or not. Can anyone help as Haynes is as useful as ever on this matter?
