This is a word of caution to premium and LE owners. Check the shimming of the bell and ensure the opto interruptor DOES NOT hit the opto! On my Luci, the bell pivot hinge has about 1/4 inch play and that allows the interruptor to contact the opto. Ultimately this could lead to the opto getting snapped off the board. I'm glad I caught this in time!
Maybe this was covered already..?
