After several posts, many great people trying to help and much searching I am still having no success.
Symptom
Bike starts with choke on first try every time
Idle fluctuates when choke is on up and down
As soon as choke is turned off bike dies. I can only get a little past half closed
If give gas when choke is on nothing happened and bike wants to die
Things I noticed
When trying to give the bike gas the throttle slides shudder
When giving the bike gas I can hear a whistling or could be vacuum sound
If I spray carb cleaner in with choke off bike revs up good
This is what I have done
New plugs
Carb cleaning
New fuel lines
Turned up idle
Turned pilot out 3 turns from full closed
Made sure slides moved freely
New battery
Running bike on prime
Fresh gas
Verified fuel flow to carbs
Blew out vent line
I have no idea what to do next aside from heavy drinking.
can someone please help?
check the o-rings for the vacuum caps on the slide covers, and check the diaphragm for you slides. Thats all I can think of..............sorry hope one of em works ( preferably the o-rings they're cheap, and new slides are very not cheap)
You have a vacuum leak.
Make sure the carbs are seated.
Make sure the airboots are sealed all the way around the carb mouths.
Make sure you have the little o-rings under the black caps, as SpcTerry has stated.
Make sure the vacuum line is attached to the inside of the left carb, and to the frame mounted petcock.
Going back through your posts, I wanted to clarify some things:

Also when I pulled the tank there was a long hose laying on top of the motor. It is the hose that connects to the T connector on the carbs. Looks like it might go in the painted fitting under the tank. I can't find it the connection point in the clymers manual it only shows where it connects to the carbs.
That is the float bowl breather hose, it does not connect to anything; usually it is draped over the airbox and ends between the airbox and batterybox.
Thank you very much for the help.
I will tackle the vacuum issue tomorrow.
Don't ask how I know that about the o-rings..... :oops: :oops: Taught me to rebuild my carb in a hurry!!
