There is only one timing plate. Both sets of points are mounted to it. You do not adjust timing for right and left points separately. Once the point gaps are set, timing for both cylinders are adjusted together, as you rotate the plate.
I found this statment I made to be not completly correct. While adjusting timing on a GL1000, the manual states, if left and right timing don't match, adjust right side point gap until timing on right side is correct. I was suprised at how little adjustment to point gap changes timing. The bike idled much better with timing on both sides identical and point gaps slightly out of spec, than the other way around.
The last time I tuned up the KZ305 I set point gaps identical and split the differance on timing, left a bit too far advanced and right a bit retarded. This time I set left point correct and set left timing correct, then set right timing by messing with right point gap until right timing was correct. The KZ305 is starting and idling much better now, even though right point gap is slightly larger than it should be.
