Gotta thunk a bit more on it. However, given that all the voltages/voltage drops are OK, and listening to the recording, I'm back to thinking it's a starter issue. Something in there perhaps binding just a bit. (The whining noise as the starter spins down.) Gets tighter when it's hot. Assuming the starter bearings are all greased properly, try the 'hammer alignment' technique.
Remove the starter. Then, while holding it in one hand, hit it around both ends with a plastic hammer. Don't try to break it -- BUT, make it felt. A 'tap' on all four sides at each end.
P.S. Similarly, light taps on carb bodies can do wonders for seating float needles and floats after rebuilds.

I took the complete starter apart and do not see any issues apart from the brushes nearing the service limit...

I'm not anywhere near an expert on the CBX starter. My suggestions are based more upon having rebuilt other 'small' motors and rotating things. Seems that regardless how hard one tries, they don't bolt together in perfect alignment. So, a couple taps around the housings at the bearings has usually been helpful. As best I can see in the photos, it appears that something has been 'polishing' the cores in the housing. Either alignment or bearing wear. I would not think those bearings would wear, particularly.

As for the clutch, someone else will hopefully have some good feedback there.

Thanks Larry. I used 2000 grid water paper to polish the armature on the lathe. I may just be the photo but nothing touches anywhere... I am at a loss here! Regards!!
