Hello, I have a question if anyone can answer it I would appreciate it a lot. I have a 96 FXDX dyna with a 80 Evo motor in it. A few months ago I was riding and all of a sudden the motor started sounding and acting funny. It is like a high pitch noise coming from somewhere. I started looking around and noticed there is metal shavings in the air cleaner and all over the bike. Seems to me it was coming out of the carb or motor. Does anyone have a idea of what could be going wrong? Thank you... Anthony
