It would seem to me that if the bike starts good from a cold condition and once warmed up it fails to idle, the most probable cause is the choke not shutting the fuel off completely and it starts flooding. You could see this with a black or carboned plug.
If the plug stays clean (tan) then you are still having a problem with the idle circuit.
When the choke shuts off the fuel, the idle circuit takes over. It is critical that the idle jet is clean and unrestricted. If the adjustment screws don't make a difference at all, the circuit is clogged.
