TOPIC:

Finally got all the carbs rebuilt (all hydrablasted, washed and blown out and fitted with new kits) and am about to connect it up to the fuel system.
I'm a bit mystified as to how it all goes together - the carbs were disassembled when I got the bike and hoses etc have long since vanished.

No probs with the drain hoses (item 39) and the interconnecting short hoses (item 37) between carbs 1 & 2 and 3 & 4.
Also happy with the 2x 2 way and 1 x 3 way "nipple, fuel hose" (items no 42 and 31) on the parts list (attached) and how they join the carb bodies.

I'd like to know where do hose, fuel (item 34) and 2 hoses (item 38) connect to? :?

I'm guessing that one end of each hose (item 38) connects to the the rear facing pipe on carbs 2 and 4,
but where do the other ends go? Also where does the upper end of item 34 go to?

NB: '78 Z1-R does not have a vacuum operated fuel tap and the fuel tap has only one outlet pipe.



(Hope somebody can work out wtf for me!)

Each of the two bowl vents exit to open air, usually through a hose . The stock hose was probably routed up to underneath the seat. Sometimes the vent hoses are routed down along with the bowl drain hoses to exit underneath the bike.

The fuel hose connects the carb fuel inlet tee to the petcock nipple. And it's a good idea to install an aftermarket fuel filter in the fuel line between the petcock and carb.

The carbs at hand likely don't have the vacuum nipple or the fuel pump shown in the diagram.

Good Fortune!

Yes the yellow lines on Pattons post are they atmospheric vents spigots.
Generally hoses run from these to over the top of the air box as such.

Here's an example on a stock 1976 KZ900-B LTD of how the two carb vent hoses are routed to exit to open air underneath the seat.




Good Fortune!

The vent ports are on the carburetor bodies.

A big thanks to all those who responded to my request for help!!
All embarrassingly simple when it's explained properly

Anyway I can now get those bad boys back together and on the bike,
just gotta get some hoses and clips of various size.
Cheers!
