Hi, So my GS won't run smoothly. And some iginition part has been change (signal generators and spark wires and plugs and also new altrenator)

So There is still problem with getting RPMs up and exhaustpipes get damn hot very fast.

I have think that there might be some problem with valve adjustment (exhaust valve carries or something)

or something with carburators. (those I have cleaned up but no use.) and using Choke don't make any difference. (exept when warm engine stops)

But funniest here is that engine starts damn well and idle quite well

you may be running too rich so the engine warms up quickly when cold and idles well (as if under choke) but dies when choke applied when engine hot?

so, i'd check the valves first and then move onto the carb adjustment - by reading the plugs

It idles well even when engine is warm. Starts damn well when warm and very well with cold engine (cold engine with choke).

I Didn't get any improvment even I remove airfilterbox lid. I'm very confuse with this bike at the moment. Is it possible that CDI Box has lost "timing" so it won work in higher RPMs
 
sorry, from your desciption i'm no longer sure what exactly is your problem

i would still look into:
adjusting the valves (so you have a good background for adjusting the carbs)
make sure there are no leaks in the intake system
sync the carbs
do a plug chop at low throttle and adjust the carbs screws accordingly
