If you are going to Cannon ball I would suggest doing the carb work yourself. Take it apart, and clean it. Don't just look, and say ok.... Take out every part, and use Brake Clean to blow out the jets/passages. The dealer will hit you for 200.00 bucks plus or minus, and you still will know nothing about it. I use sewing needles/torch tip cleaners to clear the jets.
I answered your other post too. It will be MUCH easier for everyone if you get your answers on one thread, and let one die.
There are loads of Youtube videos on GY6 Carb. cleaning for a guide.
