That is a good discussion. Some tangible technical data as well ref volume of plenum. All sounds very doable. Worth bringing that thread back to the
fore and see if any of those have done some further developments.
Interesting pic of R1 carbs at the end Im sure they are TB's?

Jacko,
I've had a good look at your photos again - very useful. I was wondering how the pipes could be formed and aligned, then I saw your manifold
jig. Very neat.
I've just bought a set of CBR600 carbs off the bay of e, so look forward to many more questions!
cheers,
David
Hi David just ask if i can help i will
By the way i tried to do 4 vacuum pipes with a container with and with out one way valves and without container this was for a vacuum type dizzy
but it would not work right
but please try for your self and let the world know if you get it to work

I've got an R6 fuel pump feeding a set of R6 carbs, held onto the engine by a bogg bross manifold, the set up ran straight out of the box from
boggs 
Just need to sort a filter now , oh as for a cable, I used a push bike long brake cable and reduced the nipple on the end to fit the std bike set up
TPS fitted to the carbs as std, and the choke size is 34mm

I think that will work ok.
I am still running the megajolt for ignition even though i have fitted megasquirt for fuelling and found that I have a good map signal from the
throttle bodies done in this manner.
Anyone using megasquirt with ignition will also be using the same method .I also fited a .6mm mig nozzle before the resevoir to damp any
fluctuations.

Not sure about the TPS yet - it wasn't stated in the ad.
However, I was planning to make the manifold with a vacuum take-off on each tube. These will go to a small reservoir then on to my current MAP sensor.
Other people have done this, and apparently it works OK.
I don't know the size of the tube either! Awaiting delivery...

As a matter of interest, can CBR600 carbs be re-spaced?
The efficiency of straight or bent tubes is not a major issue for me, but straight manifold tubes are easier to produce than bent ones!
I won't lose any sleep if they can't be separated...

Graham,
I'd guess that the vacuum supplied to a mechanical dizzy has to do some mechanical work, unlike the Megajolt MAP sensor that only senses the
pressure in the pipe - a microscopic bit of effort.
