pickup speed hangs on my (gy6)

I have a Puma Amor 50cc which I just recently upgraded to a 80cc bigbore kit and installed a new corroborator. It still has the stock muffler though but a second hole was drilled in it to allow for more speed.

It starts off really well and picks up speed really fast but at about (hypothetically 2nd gear) it starts to lag. Eventually it slowly picks up speed and maintains the increased power. Not sure what it could be. Any advice is greatly appreciated
