I cleaned up the clutch slave, flushed the fluid and changed the oil, but it's mostly the same.

The bigger issue is that when I start it in gear, the bike will move forward a bit. I can hold it back with my legs, and once I run it a bit, the issue lessens. But I wonder how I would know if the slave cylinder is moving enough? Or is it something else?

Any thoughts? Thanks.
Man, I've had this problem on my 2007 S2R 1000 plenty of times, here's what you can do:

Have you washed the bike recently? If so, the friction plates will stick to the steel discs if they were allowed to dry without riding it after the wash (rust). To resolve this, start the bike in neutral, let it warm up, and pump the clutch handle repeatedly; it will work eventually.

Have you replaced your friction discs recently? I did several months back with a kit from an online shop and the stack was too high (it does not take much); I ended up removing one friction disc and replacing with a worn one from my old set and then ordered a new Barnett stack of friction and steel discs from Amazon. That fixed the issue. Everything needs to be in the proper order as well.

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.
