Bog down and hesitation after installing performance camshaft

Hi
I have installed a performance camshaft in a Chinese clone of Honda 70cc engine.
The can shaft has high lift lobes.

It bogs down after half throttle and seems as if timing is advanced.

Cdi is normal non adjustable one.

Do I need to do anything else for it.

Did you change the carburetor main jet with a bigger one?

after looking at images, its clear that you havent actually installed the game.
So you need to do that first... and then you can start adding mods.
