I've witnessed the same phenomenon over the years with many different bikes of all makes and I know for a fact the clutch was adjusted correctly. It is the oil that makes the difference. My current bike, a 1999 Victory V92 is shared sump and shifts like butter the first 500-700 miles but then gets notchy and stiff. I know the clutch is correct and it does not rotate the wheel when on a stand with the clutch engaged.
Mine actually shifts decent when its cold, say for the first 10 miles but then gets progressively worse as the oil gets hot. This is when I know its time to change the oil and directly equates to oil shearing and thermal breakdown. Current fill is Lucas Syn 10W40 MC oil. It lasted much longer than the Rotella that was in there last OCI.
