Connecting vacuum gauges to each other?

Question. Does it make any difference to connect the vacuum gauge attachments with each other on kawasaki Z1 carburettors ? Carb 1 and 2 with a tube and 3 and 4 with a tube?

You CAN'T connect 1 & 2 together. You CAN'T connect 3 & 4 together as when one piston is down the other will be up and they'll reduce the vacuum on the induction cycle for each piston. 
You CAN  connect 1 & 4 together and 2 & 3 together though. 
All it will do is equalise the vacuum between the two connected cylinders which should smooth the idle a little. 
That said set the vacuum properly on all four cylinders and there's no need to connect any cylinders. 

Warren answered Your query but...was that what you were "really" asking or did your Real question get lost in translation? 

Yes it was just a question,  just a mindblow and a clear answer.
Good forum

The only reason to connecting the "non carb vacuum gauge attachments" with each other together is to verify and set/adjust high quality sync gauges i use.

 
 
 
 

Those look fancy, Medical Grade/Expensive" Scirocco!! Don't drop them, haha.

Bought my BOEHM vaccum gauges in 1996 for 200 DM = 100 €
In 2023 the BOEHM company has stopped production, last price 249 €
Today you have to pay 200 € for a used and 320 € new BOEHM vaccum gauge set.

This is "version 2" of my own design, Digital Carb Sync. tool.

 

Sensitivity, range, and "damping" is easily adjusted by the 4 "touch" keys on the front panel.
Digital (software) filtering and damping alleviates the need for any "restrictions" in the tubes.

Is the screen above the 'Tune Rite' moniker the vacuum display for the 4 cylinders?

What is the resolution in in. / Hg?
