Picked my new bike up today, spent 5 hours on the Queens highway but as always when it involves a bike, well worth it

The photos dont do the orange paintwork justice, it is a candy orange absolutely stunning
Take those pods off and try it again. those pods often cover the venture on the carb bell and the pleats cause turbulence on the inlet and this effects the diaphragm lift and smooth running.
if not using factory air box Uni filters are best.

Gday Leslie Nice Bike
Two things jump out at me. First, and probably the easiest to check, the pleated cone filters look as if they are pushed onto the carbs a bit deep. There's a lip on the inside of that filter and it could be obstructing the passages in the bellmouth of the carb. Loosen the clamp and pull them back a bit and try again. This is just a test as those filters will probably have to be changed for Unipods anyway. It'll always be a bit of a struggle to get it to run clean with that type of filter.
The other thing is with the set up u have, filters and short pipes, it could be running a bit lean or rich if its been overcompansated for.. The thing is to find out which way to go.
Whilst u fiddling with the filters, take them off and try it again to see if its better or worse.
I use an old Colourtune (remember those) to find out if i'm lean or rich, still saves a lot of time.
Next are the air screws but u may be out of range on those. Read up in the TECH SECTION, full of insight from the Gurus there. These are tests u can do with the carbs on the bike.
The BIG BIG thing with carbs is one adjustment at a time then run. If u do too many changes u wont know where the hell u are or what made the difference.
Good luck mate, it should be something small as the bike looks as if it was built by someone who knew what he was doing.

Skull, U beat me to it, goodonya mate.
If it has been sitting for a while, and only runs on the enrichment circuit, it's likely the pilot jets are plugged.
Congrats on the beauty bike!
