I have recently rebuilt the control head of my BJ8 which has a Mota Lita steering wheel. On the right hand indicating, it self cancels however on the left hand I have to manually cancel. Before putting it back into the hub, it worked on both sides when I moved the self cancelling lug past the respective mechanisms. Could it be the positioning of the disc which is secured by the three grub:fat: screws on the steering hub causing this to happen?
