Except, when it's been ridden for a while, and the engine is really hot, and the bike is stationary, it become difficult to shift into neutral from 1st or 2nd. It can also require more effort than when the engine is cooler to shift from 2nd to 1st when stationary. I also think that when this occurs there is the faintest creep forward when the bike is in gear: it can require more effort to push it backwards than when it is in neutral.
Does anyone have any thoughts or suggestions?
All other members comments are good!
Based on your good observation, I would say you may have one to three combined or separate clutch issues:
1. the clutch plunger does not have required stroke/movement to completely disengage/separate clutch plates due to: air, contaminated fluid, clutch master pump/piston blow by or/and slave cylinder piston blow by, and this could be consider as hydraulics. Also check for wetness under the left side rear engine cover, not necessarily leak or dripping clutch fluid, would indicate slave master cylinder unnoticed weeping, fluid level lower than normal??, pull off the cover, if there is no leak, the clutch fluid reservoir should always maintain constant level.
2. you also may have an issue with worn brass/soft bush #2/parts - its seat becomes too deep by constantly being "attacked" by clutch master cylinder steel/hard rod and your clutch have a short stroke/movement

3. as to the slave cylinder #8/parts, under the left rear engine cover, check if three M6x75 #26 parts - long bolts are intact, not loose or have stripped thread

Q: if you take off from the 2nd gear, do you fill clutch slippage?, if not your clutch plates should be OK
Q2: Clutch lever feels funny, spongy, weak..or different before this issue
Q3: Did you change engine oil or its brand
