I was watching a video a few weeks ago, before I started my rebuild, about one of the possibilities on why the Bendix will disengage when trying to start my bike. In the video he shows the c clip, with the little hook tail on it, not fitting into the slot in the case. He squeezed it shut a little more and made sure it would slid in the slot and he said no more starter problems. Took my gears off last night, and sure enough.....it doesn't fit in the slot.
