New plugs, new air filter. Cannot check advance as bike will not rev in order to check.

it could be worth trying an ignition coil, they are a bit of a pig to get reliable test readings from, best bet is to try a known good one if you can lay your hands on such a thing.

Red neons to check for HT loss, until you do just keep pulling your hair out...
Rule out, or rule in ign loss...
Does it rev on cold start up with choke on and you can hear/see the choke butterflies " flapping"...
I assume carbs assembled and bench balanced properly, float/fuel level and throttle butterflies ?
On start up with no choke, the dash pot pistons are seen to rise/flutter ?
