Whenever gear of your bike (any vehicle) changes this event is triggered. On event-triggered adapted models will be rotated in the Z axis. To adapt name your component as
fc_cl. Optionally you can choose a time for the script to wait in-between the rotation. For that add a suffix
_ms(wait_time) (milliseconds). By default, the script uses 1 ms as wait time. Also if you need to tweak how much angle it changes you can do that by adding a suffix
_az(angle). By default, the script uses 17.
