Mini bike slow and won’t work

I have a Coleman b200 NOT the b200r i mean the one with the torque converter. it was really slow at first like 25 mph. I then twisted the throttle limiter screw back and it went like 30. then I put on a go power sports b200 kit stage 1 which was like 150 bucks and it goes 35. I’m pissed cause it’s still slow af and it’s not working right but i dont care about that I can just fix it. I wanna know what i can do to make it faster. I thought the kit removed the governer but now im thinking maybe it didnt because people say it would go faster if it really did take the governor away. Im thinking about taking the kit of my current engine and putting it on a 212 and then put that on my bike but then I wouldnt have a torque converter anymore. how am I supposed to make this thing faster cause I feel like people make there mini bikes go like 60 with 3 dollars and a becket of screws and mine is just slow asf for no reason?
