The issue persists. I'll try bleeding the line again, and disconnect the zip tie at the frame pivot to see if there might be air stuck there.
One thing I notice, is that after the bike has sat for several days, there is a bit of a clunk when I first pull in the clutch. Like something was sticking. I think it might be coming from the slave. Once I pull the clutch in once, the sound won't happen again unless the bike sits for another couple of days.
