O.K. I got the side fairing off. Started her up. Quiet at first, then as it warmed up, about 1 minute, I heard the rattle. Not as bad as before, but heard it. It is coming from the CCT/ignition pulse generator area. I can feel the CCT and it's feel correlates with the sound. I just put the CCT in last year. Double green dot. It does not have the same "rocks in a can" sound as usual for a failed CCT. Plus the sound is at idle and above. Not the usual 3500 rpm area.
The sound changes with RPM rise.
I am going to pull the cover for the IPG and see if anything is noticeable.
