80 Yamaha still not right, shop wants to replace all 4 carbs

Anyone have any information on how these would relate to say the Lucas brand additive "Fuel Additive, Fuel Treatment, Upper Cylinder Lubricant and Injector Cleaner"?

I purchased some of this stuff and was going to give it a whirl this weekend... below is a link that describes it's (advertised) benefits in greater detail.
