I have a 2004 FXSTI with 69K miles. This morning when I went to start her there was a rattling noise coming from the primary area, then she died. It sounded like the primary chain came apart inside and locked the motor up. When I took the primary cover off everything looked fine. Can anybody Please help me out here. I know it is hard to tell what's up when the bike is not in front you but any help would be great. THANKS, Chopsaw in FL.
