My motorcycle <<<movement problem>>>?

Question:
Is it the carborator, electric problem, gas problem.
I have a 50CC yamaha motorcycle. I bought it just 2months ago. First it moves with alot of power. It has three throttles. On all 3 throttles it had power to move the cycle with speed. This cycle it was already was when i bought it. The cylinder is bigger than the normal 50cc.
The problem: Now when i shift from throttle 2 too throttle 3, it goes smooth. But when I hit the brake to stop (example: from 50km/h too 20 km/h but not totally stop) and give gas afterwards. I know it takes a couple of seconds too make the cycle move 40km/h at the 3th throttle, but mine it takes more than minutes to make the 40km/h(or goes slower) So maybe i was thinking about changing the bougie or cleaning the carborator. Still the same problem accured. So than i thought of maybe the Motorcycle Electricity, it doesnt gives the full potential electricity i wanted. So can anyone help me with it? Suggestion, advises....
Thank you in advance.

If you did not check the needle in the carby? Do so because it could be an factory defect, it could not be feeding the fuel at that speed or throttle response.

Electra Glide or Goldwing?

Check the pulse rate for the electric motor in accordance with factory specks, and this could also tell you if it works or not.

Does anyone know of any motorcycle shop websites from andorra?

Another thing you have to consider as you say the motor is bigger than a 50cc, you might need a bigger carby and slightly larger diameter fuel line to compensate the starvation of fuel to the motor.
