Help with set up for Top Performance Due Plus

My set up on my Yamaha Aerox is not powerful as it sout be.The cases are ported to the limit and polished.It runs bad and a lot of bogging can't get speed.
Cylinder Top performance Due Plus tuned for 20+BHP.
Exhaust Lazer X Pro
Carb Delorto 21mm with 0.80 main jet.
Variator Polini Speedcontrol 4.5g weights
Cluch Polini for race 3
Crank Rito

Sounds like it needs a good service. What colour's the spark plug.

Could the ignition curve be stopping it?

It's all oiled and black.

Maybe but i don't have another one to test.

Still running the stock CDI?
Also if the plug is black it's too rich.
What air filter

Yes i run on stock CDI.
The filter is not branded but its a good filter.

Foam filter I guess?
I would be looking at the carb jetting.
