Bintelli

Well ok im new at this i have a 2021 Bintelli Beast 49cc an im just wondering how to make it go a lot faster than it goes now it goes up hills really slow its not as fast as i thought it would be so could anyone let me know everything I have to do or what parts I need to buy please thanks if you dont mind let me know every parts names an how many or whatever

Same here it's the hills that are super slow

Yeah mine is still slow and I have put in a new CDI, Carb, and spark plug so I would guess just put in a whole new engine.
