Timing chain wear can be seen as a flutter when strobing, but it's too rapid to have any effect on idle speed. Hunting is usually carb wear especially if it changes with temperature.Compared to my other Brit bikes the Commando's seem to "hunt" a bit at idle. I'm wondering if minor flexing of the timing chain is messing with the advance. The timing chains definitely have tighter and looser spots when adjusting tension. These bikes all have Pazon Surefire ei's. Maybe the timing chain flutter would be less noticable with points with centrifugal advance.
