Before you go sealing tanks an such...................
You said when you start the bike, on the choke it's fine but if you give it gas it dies...?
If you leave the choke on for about two minutes, and then rev it does it still bog down ?
From my experience - my own bike doesn't like ANY throttle on startup - just full choke for a minute or two, then a couple of blips on the throttle. If I give mine throttle when cold, she will stall. If I touch the throttle when starting, she won't start.
I did refurbish my tank with a ceramic compound, BUT REMEMBER - there's a breather in the tank behind the filler neck, a thin metal tube which runs out under the tank....before you cream it or whatever push a wire up the breather,and leave it in when you do the creaming, and then remove it......... or it'll block and you'll have even worse problems. I speak from experience here, I had to fit another breather because mine blocked, and after the vacuum builds up the bike won't run !
Just for info !

 

I had let it run for 10 minutes or so, and it still died when I would touch the throttle. Thanks for the info about the breather... Didn't think about that.

 

Sound's to me like she's flooding, but hard to tell from 10000 miles away
