s2r 800 clutch slipping? or just weird aptc clutch action i cant tell, help!

The sight glass fog is a normal thing. There are a lot of threads about it. You just need to take it for a spirited ride and get the temperature up. Then when you come up park the bike, shut it off and remove your oil fill plug. The moisture will evaporate. Sometimes this takes a couple times to get it to go away.

As for the slipping I know one of my services the dealer put in semi-synthetic. I noticed some slipping and my plates would stick if the bike sat more than a couple days. I switched to Mobile 1 and both problems went away. After that I went to Amsoil and stayed with that until I sold the bike.

I think it would still be a good idea to take off the side cover and inspect. It may cost a little money now but that's better then having everything fail on you.
Do you have the workshop manual?

i don't have the manual. however I went on a HARD 5 hour ride yesterday after the oilchange and it's still slipping, but im noticing that it's slipping only when i use the clutch between hard, high rpm shifts, with no clutch I can't make it slip, not full throttle bogging, not hard open closed throttle changes at high load, I even tried hard open closed throttle action at 100MPH, no slip at all so im starting to think the slave isn't releasing fast enough.

Sounds like progress.  If it still bothers you (who upshifts with a clutch?) bleed that system and verify lever adjustment as already described.  Also make note of the lever feel/free play between cold/hot.  Just for good measure you can remove the long clutch rod from the slave side to make sure it's straight and smooth.  You might want to bleed the piss out of the clutch hydraulics to ensure complete fluid change and use an unopened/sealed bottle of new fluid.  If it's a funky coffin type MC, they're actually pretty cheap from Brembo dealers.  The APTC system has such a light disengagement pressure that it doesn't take much of anything to cause a slippage issue.

You can adjust the lever play with the S2r800??? I did not know this, will have to adjust mine, grabs way too high.

bleeding the clutch slave and cleaning the actuator rod seems to have fixed it, i think it was dragging on clutch release.  rode hard for 2 hours with a passanger up hill in the twistys no slip.
