Some considerations.
The throttle cables need to have a prescribed amount of slack, usually the "pull" one is adjusted only. A rudimentary test is to turn steering from lock to lock and blip throttle (while running) at each extreme .... any change at either end, then it needs more room to play with. I can get the spec from manual at twistgrip if you need it.
There's concise method to setup idle circuit jetting if they're been apart before, that's in manual, to get them on aim for mixture. This can get them "hanging " as described if not fully understood and implemented.
Choke should give up to about 2,750 rpm fully out, but obviously when fully home shouldn't be lifting the throttle slides at all. Also data in manual to set that correctly.
