bogging & jerking at full throttle

[new_bee]

So previously I had a (some what-not identical) similar problem thatthat went away when I finally put a new diaphragm in the top of the carb. The previous person had pinched the rubber outer or ing sealing serf ace (the old diaphragm had expanded)..

The bike was running great for a couple hundred miles.

Now a new issue gradually developed, and I have been through the carb so many times, just beating my head against a wall trying to figure out what I could have missed.

Basically the bike runs well upto about 3/4 throttle, and if you accelerate fast from that point it starts immediately bogging down and jerking , feels like it is not getting fuel. If you gradually accelerate at that point can get it to slowly speed up to about max rpm/speed in each gear. Only notice the issue if heavy throttle, quick acceleration

-could throttle cable adjustment have anything to do with an issue like this?

-anything in particular I should pay extra attention to when I pull the carb apart again today? carb has been clean and no sign of any dirt or build up the 5-6 times I have been through it. All passageways not clogged checked with carb spray and air.

I have new fuel filter, no air leaks around boots, new plug, checked valve clearances, checked petcock screen, and tank is clean fresh fuel.

Any suggestions very much appreciated
