Also if I wanted to convert the lite to a rear motor. Is there anything else required besides the B5 conversion?
doing this from memory.. to go from 3 gear to 4 gear, you would need the 4 gear box (v2 for better mesh), extra idler gear and 2 bearings for it, non-v2 top shaft with 2 more bearings if I'm not mistaken. The v2 top shaft is meant for the 3 gear with smaller bearings.
