New issue with my bike, no error codes or warning lights by the way. The shifting up and down does sound sync too. When shifting up no issues, when shifting down no issues, but when I release the throttle I heard a loud clanking sound in the front. As soon as I accelerate, the noise is gone, only when I am in coast mode between down shifting and lowering my speed. I checked the oil level and it is perfect. Any ideas, I will have to make an appt with the dealer.
