Chain rubbing on clutch slave

Need some help!

Picked up a 1098 today and noticed that the chain/rear wheel was dragging. Pulled off the front sprocket to find that the chain was eating into either the engine case below the clutch slave or the slave itself. Previous owner told me that the only change he's made to the bike is pulling off the quick change sprocket set up for OEM (chain and front sprocket untouched). Any idea what can be causing this?

Hmmm, front sprocket too big would've been my first guess followed by incorrect chain size. If we assume they were untouched like your seller told you, then I'd have to say chain growth. How old is the chain? And is it adjusted properly? If he had a larger rear sprocket on and just swapped it back for OEM without readjusting the chain that could hurt too

Turned out to be the clutch slave cap (on the backside) that came loose and rotated towards the chain.

Thanks for your ideas!

that could be a sign the clutch pushrod might not be spinning freely. not good for the slave. check the condition of the pushrod and bearing it sits in on the other side. a stuck bearing will cause the rod to spin inside the slave.
