Hello all,

To those who have done the superior shift kit for the k1 and k2 valves. Does the new spring (purple for k1 and pink for k2) replace the small spring PLUS the springs in the plastic holder AND the plastic holder itself? That is what I am reading in the instructions, but I just want to make sure. The way it looks in the diagram, the plastic holder was needed so the small spring had a place to seat.

Thanks in advance!
