One of the other electrical genius here can probably correct me-The stator provides voltage to the regulator to run lights &charge the battery and to the CDI (black box or capacitor discharge ignition)for the coil and then to the spark plug. The CDI regulates the spark by advancing the timing through rpm range-If the stator is damaged then it's not providing the right amount of current to the CDI, thus no advancing of timing at higher rpm's.
What tooth sprocket did you get from the motorcycle shop?If it's a few teeth off then performance will change. A 50cc engine would do good to propel that buggy to 20mph. Transmission damage is usually going to have a noise associated with it.
