Hi All,
I bought a basket case kz1000b and I'm putting it back together. Today carbs, which came in a bag. I'm seeing the fuel line is the rail at the bowls and there several vaccum lines. To the petcock and the clean air system I think. Anyone have a diagram for these lines and fuel lines? I see four air line attachments and two fuel? I'm not running the clean air system, any advice there? I have the original fuel tank with petcock so I assume theres a T that connects the two fuel rails to the petcock and the other to a vaccum line. Help

Your carbs might look like these.

Similar to the photo but not those

You should have 26mm carbs with accelerator pump for the b model, which were not very good as they have two diaphragms and never seem to pump properly, on my b i modified these parts so they behave like the 28mm carbs. Here is a picture of what you should have on yours. The yellow pipes are fuel feeds you should have a twin outlet petcock, not vacuum operated, the red pipes are breather pipes and go back to the air box opening under the seat, the green link the bowls so when the pump operates fuel is forced out of the injectors at the air filter side of the carbs, if you have a brass stub where the blue ring is that would be a vac port for a vacuum operated tap as you shouldn't have a vac tap this should be as the picture,. you will also have four brass stubs on the rubber manifolds, these are for when you do a final balance on the carbs and should just have rubber bungs on these, hope this is of some help. a picture or two of your carbs would help us identify yours much faster.

The intake manifolds each have a vacuum line attachment. For balancing the carbs I assume but two point up and didnt have caps. I read these go to the clean air system and do on my 650csr. Theres also two that I think you mentioned go to the air box that are near the fuel inlets. There wont be the clean air or an air box so advice on what to do would be good. I assumed cap the manifold and allow the air filter side

Just cap the ones on the manifold, the other two breathers just run pipes to the open side of air box under the seat , this is how they were from new. and how mine still are.
