Banshee bogs on take off.

Here is my problem I am having trouble with low end power. It bogs as soon as you take off. It is impossible to wheelie even with pulling as hard as you can, but if it just sits there and idles it is fine. When you rev it, it feels smooth and comes right back down perfectly. It is only when you crack the throttle. The mid range and top end is fine it runs good. Once I noticed this I did so much LITERALLY 200 hours of trial and error. Nothing worked so I rebuilt the entire motor. Hot Rods crank, new pistons, everything, I mean everything. 800 dollars later I fired up the new engine and it did the same thing. Bogs off idle. I feel like it would have to be carburation at this point. But I have tried all jets and needle positions and nothing works. My new motor has 150 psi in both cylinders and no leaks (with tester). Carbs are spotless I'm running 30 pilots and 340 mains on the third clip. 30 might sound big but thats what the bike likes at idle. Please comment with any suggestions. Thank you.

Ya carbs are completely clean ive literally cleaned them probobly 10 times. I took out the main jet tube, pilots, air jet, neddle and seat, everything. And turning my air screws out makes me more lean and my idle revs out to limiter. Or it will hang really bad. I feel like me going to 32.5 on a mostly stock motor is way to much but thats what it wants idk.

2000 ft and its 20 right now but summers are 80. And just to explain again the mid range and top end hits power band and runs as should its only right off idle when you give it throttle when it bogs. It makes it impossible to ride hills because at that low rpm there is 0 horsepower.
