Here are some additional factors that can influence the top speed of a 196 cc go kart:
* Engine modifications: Adding a performance exhaust system, air filter, or carburetor can increase the power output of the engine and, in turn, the top speed of the go kart.
* Driver weight: A heavier driver will cause the go kart to accelerate more slowly and reach a lower top speed.
* Tire size: Larger tires will roll more easily over obstacles and reduce rolling resistance, resulting in a higher top speed.
* Terrain: Driving on a smooth, paved surface will allow the go kart to reach its highest top speed, while driving on rough or bumpy terrain will slow it down.
It is important to note that go karts are not street legal and should only be operated in safe, off-road environments. Always wear a helmet and other protective gear when driving a go kart.
