You can always get it sleeved. There are brake master cylinders hones
that will work. Or, you can get a wooden dowel (small enough to fit
in your drill), cut a small slot in it, put a folded piece of fine
grit sandpaper (like 600 wet) in the slot, and spin it in the bore.
Keep it wet, and pay attention, but you can clean up the bore this way.
The dowel method works especially well on aluminium bores, like on
motorcycles. A good cleaning can do wonders, and since it's a clutch
MC, and therefore not a safty item, I would try the 'home' methods first.
