The bike wont idle and cuts out. Weve run carb cleaner through the airbox at high idle, checked the seats and needles on 2 of the 4 carbs and done the spark gap tests all of which came up fine. The colour tune looks ok when we hold the throttle at a idle speed. Our only thought now is to reset the idle screw settings even though the thing runs a bit rough at higher revs. Any thoughts??
Check for vacuum leaks ,around intakes

I have seen this before a few things to do too make sure. First take the air filter out and shine a light use your fingers to move the slides up and down I suspect the springs that go on the slide is not seated in center you can tell from the slide going halfway and hanging up. Next, the boots on the slides only go on 1 way there is a notch on the carbs for them. I would guess this would fix you up if not we can get deeper into it with air-fuel mix screw settings.good luck

i had a similar problem on a suzuki gs250t custom, my bike would not start some times and if did start, would run erratically, and cut out, this was after i changed the spark plugs, found out that the supplier gave me the incorrect graded plugs.

You need to fix the fueling first - without fuel it won't run!
Your other problem sounds like an air leak - either the manifold or the carb. Check by spraying WD-40 or CRC at the manifold and carb join while the bike is running - if the revs change (either up or down) you have a leak.
