One thing to check is the clutch, I have raced with you and know you can tune an engine
So I doubt its that but after it starts bogging set it on the box and rip on it to check it without a load.
I had a clutchbell that gave me the same effects, whether I dremeled it or not it still gave me a bog after warmups. I changed the bell (of course after changing tanks,line,shoes,carbs ect ect. And the problem was solved.
Either way maybe something to check. Lemme know what you come up with
