I too am interested. I had a bad upper coil on the left cyl, I had trim bank 1 values of .3 and trim bank 2 values around 3000. After replacing the coil and resetting adaptations they are both in the 3000's now. Valves are in spec, tb sync is good. I don't know what normal is and can't really find any info on it. 2010 1200gs
