CV carburetors – Hose diagram

I was recently working on the Zebra 2000 Yamaha R6 and found myself horrified at the unbridled growth of hoses and pipes connecting the 4 carbs to the rest of the machine. In an attempt to clean things up on sought advice on several forums but failed to find a simple, clear diagram explaining the function of each hose and where it should connect.

I designed the following diagram hoping it would help fellow week-end wrenchers better understand some aspect of their carbs inner workings. It is relevant to most carbureted, water-cooled inline 4 engines.

This does not apply to our DRs
