The bike downshifts on its own I'm just along for the ride I'd make a vid but I have an exhaust so it probably turn out badDig125, it sounds like you may be downshifting into red-line plus. That can cause a lot of problems. I once saw a piston from a car doing that and it looked like a potato.
As for the ticking, I have no idea what that is. Can you post a video of it making that sound?
