It will bog down then die when going 52 mph (fully open and as fast as I can go) never really went further than 1 mile at full speed.
Sometimes it will stall when I am down shifting.
Occasionally hard to start when cold.
Whenever it dies on me I have to wait about 5-10 mins before it will fire up again... then it will go about a half mile before dying again. (I always end up pushing it back to my house.
Carb has this sucking noise whenever I give it gas

Here is what I have done:
Oil change (10w40)
Valve adjustment (.002 intake .004 exhaust)
Braided silicone hose on secondary air injection (Factory one burst)
Continually have tried adjusting the carb (fuel/air screw)
Took carb apart and inspected everything (105 main jet, idle jet did not have a number on it?)
Put 1 then 2 then 3 washers under the needle (this helped with cold start but still died on me!)
I even got pissed off and bought a brand new pz30 carb.... same thing!

Any help would be greatly appreciated.

Sounds like a partially blocked tank petcock or the fuel tank is vacuum locking.Next time it happens,open the fuel cap and ride on.If every thing runs properly, take apart the fuel tank cap and clean all the little holes.Do you have a fuel filter?If so,bypass it an see if it runs better.Paper element fuel filters can restrict flow on gravity feed fuel system like motorcycles.
