        Get a multimeter and check.

          What bike are you running and with what carbs? Who did the re-jetting? If that's wrong that could cause symptoms similar to what you've described.

            I doubt charging system, but checking is easy enough.

            Whatever jetting you did, it doesn't seem to be adequate since you are running rich. It would be helpful to know what carbs you have (CV or slide type) - makes a difference in diagnosis.

            There are lots of threads on rejetting carbs on this site. Getting dialed in with pods and pipes is not an easy road, but lucky for you many seem to enjoy the challenge.
