Couple of points:

You can't balance the butterflies prior to fitting the carbs to the bike. This is what vacuum gauges are for & should be done once the valve clearances have been checked & adjusted (easy on a Bandit - screw & locknut)

There are no tickover jets? I assume that you're referring to the brass screws on the front underside of the carb body - if so, these are your pilot mixture screws & affect throttle response. Unless you have different pipe etc, set as per manual.

Does the bike try to fire at all? I could understand one or two cylinders not firing but not all four?

Try charging the battery to be on the safe side. Also check that the plugs are clean, gapped & have a fat blue spark that can jump 5mm to earth.

No joy? Remove float bowls, carb tops, slides etc & blow through with an airline & try again. Ensure that the air box snorkel/inlet is not blocked.

If not firing at all, as a last resort - fit carbs without the air box, squirt/spoon/tip a little fuel down the bellmouth of each carb & try firing up. If it fires up, then it's a carb problem. If not, then there's a good chance it's electrical - coils, plugs. leads, ignition pickups, battery etc.

BTW, I'm assuming that you've tried fresh fuel? With the carbs apart, ckeck that the choke mechanism is actually operating as it should?
