How do I remove the optical gear indicator?
There are two small phillips head screws that you'll need a jewellers screwdriver to remove. Once they are removed, you twist the optical indicator counter-clockwise about an eighth of a turn and it will disengage from the shifter. Underneath the optical gear indicator is a blanking off plate that you use. It is secured using one of the small screws that you removed taking the gear indicator off.
