Hi im in need of help re a juicy bike that I sold bsck in October. The buyer msg me with an issue. Firstly she said the throttle doesn't work to assist I hills. I have onky ever used that to assist with starting off as it is my belief that is all it should be used for. She is saying the bike keeps shunting which I have never experienced during my ownership. Any advice that I can send to her to help her resolve the issue would be very nmuch appreciated.
