Tested the fuel tap, that was fine.
Fitted a fuel reservoir to the carbs and balanced them okay though they were tricky and the left middle carb wouldn't match up with the other three no matter what we did.
So we thought it was a lost cause, however it was revving much better and no sight or sound of the dramas in that video I previously posted..
So I took it for a test ride and it rode absolutely fine for the 15 mins I was out for.
Shocked is an understatement. It's not that smooth and needs a little "something" to smooth it out but I have no idea what. I may take it to a garage to sort.
Overall, It runs and pulls fine and I wasn't expecting it to run like it is.
Great evening!

If the carb isn't balancing, check the valve clearances.

As Lynx has said valve clearances are important.
Check the fuel mixture as well. I run mine a bit rich, just enough to crackle on the overrun. I did use a colortune to begin with but after a while I learnt to do it by ear. I carried a small screwdriver and made tiny adjustments to the mixture over the space of a month to arrive at my current settings.
Float height and carb cable condition can be a factor too.
When it all comes together the effect is pretty magical. I've not managed to get a garage to do a decent job of tuning engines, they get in the ballpark but you need to ride it and get a feel for different temperatures before you find a good compromise.

Not sure about the specifics of your bike fuelling system. Does it have auto choke, is the fuel tap controlled by vacuum from the carbs?
I usually go through it in this order :-
check timing, set valve clearances.
check carb vacuum levels are even.
check and adjust fuel air mixture.
You have to adjust things at operating temperature. The symptoms you are describing sound a bit like the choke still being on once the engine is warmed up so it maybe fuel mixture.
