100cc quads

What are ways to lift this restriction in a two-stroke 100cc quad?
It is a 100cc engine 2 stroke Apache, which was the accelerator Re strict deleted, it is the only mod that has been done to the bike. Basically I was wondering if other ways of achieving a peak speed higher?
It could be a fuel restriction in the carburetor.
