this prob happens allways in carburated engines that the car or motorcycle is running lean or rich . because the air - fuel mixture ratio is not right . so you should open the carburator and remove the air filter you will find two screws in the lower front section of your caeburator. you can adjust them by a screw driver until your car is smooth

Even though you probably don't have that many miles on the bike, or if you do have a lot riding time on it, it sounds to me like you need a valve adjustment. That's a high reving bike for that engine that works pretty hard so you might have 1 - 3 loose valves.

remove the two 4mm alen head bolts form the side, theses have lock tight so uses a small hammer to tap while you put preasure on them. a trusted buddy to tap with the hammer. then remove the two forward covers to be able to remove the forward two. and lift the seat from the rear.
