Hi Guys This happened to one of my bikes couple of years ago and thought of getting your views before I do the same to my new bike. So it was a brand new Honda and around 8k it started slipping the chain. When I checked why the front sprocket teeth was badly worn out. The chain was looking pretty good and it looked like the chain cold do another 8k. There was no over wear on the rear sprocket either. My suspicion was that this was caused by engine breaking. I do use excessive amounts of engine breaking and I thought this could have caused the issue. I don't use engine breaking any more to that level. What are your guys thoughts?
