No, nothing else to check. You need to completely disassemble the carb and clean it out. When gasoline left in the float bowl evaporated, it left behind the gummy additives that the refinery puts in the gasoline. This mess has clogged the jets and small passageways in the carb. The reason it runs with the "choke" out is that it is not a real "choke" but rather an "enricher circuit". It has it's own air passageway and fuel metering "jet" in the float bowl.

Good Luck

If the bike sat a long time with gas in it gums have developed in the gas and it has clogged the filters and the jets. So now the fuel flow is low.
The carbs will have to be cleaned again, either by actually dismantling and cleaning them (what the dealer did) which you can do yourself following this repair manual

or by running an cleaning additive like

Add it to the tank and run the bike for 50 miles or more.
To prevent this from happening again put this

Mine was stored for 20 years, I ended up replacing the seat and needles, cleaning them thoroughly and when I tried starting it, nothing!! No gas was going to the carbs, it turned out to be my gas pump, it was seized by the old gas remains 'varnish' so I had to clean it numerous times, soaked it in gas cleaner (short period at a time 15 minutes or so, being a very powerful cleaner, you cannot leave it for long without causing greater problems, thus I was able to get the pump going by boosting it with my car batterie, having more cranking amps directly to the pump, the pump was able to release itself from the old crusty varnish.
