Can i change my carburetor to a racing carburetor even my egine is in stock 125 honda wave?

Answer 1

You can change it, but will most likely wish you had not. Changing the carb alone will have no good benefit. To gain power, the exhaust, carb, and porting in the cylinder must all compliment each other. It is a job for an experienced engine builder. If you need more power, trade up to a larger bike, which is set up with suspension, brakes, tires, and such. You will enjoy it more, it will be more reliable, and cost less in the long run.
