Clutch slipping and high revs

I just acquired my 750 SF and am busy sorting out some issues. When I drive and accelerate the clutch slips (more revs than speed). Is that just a question of dismantling and cleaning the clutch? Furthermore, if the engine is warm it is stationary revving with 2000 RPM. Cold is revs normal. I assume I just have to adjust the carbs?

Thanks

For the clutch it might be worth to have a look under the primary cover. For the carbs, I'd rather search for an air leak first (somewhere around the inlet stubs, e.g. cracks etc.).
 
new springs will very often fix that,
clutch plates need to be measured for thickness, but the springs go awol first.

Maybe someone put Snake Oil in her and the Clutch will slip and rattle until you dissemble the clutch and burn off the disks with a butane torch - Been there.

Replace the clutch plates if I were you. Make sure you do the bejezuz nut proper tight after. Yes, adjust your idle mixture and speed and make sure you have freeplay in all the cables. Also incorrect ign timing will affect idle.
 
A few mm freeplay at the clutch lever. Just so that the cable isn't bowstring tight, which would be pulling on the clutch plates all the time.
 
I had a slipping clutch on my SF2, got some kevlar plates from Red, they worked a treat no more slippage.
