Oil change then clutch rattle!

Changed the oil yesterday on my TV200. On start up I noticed a slight noise from the clutch area. Went for a ride and after about 6 miles I noticed a bit of a rattly noise when pulling away. Got back home. When ticking over there's a slight noise when I pull the clutch in which didn't happen before.
I did put enough oil in. Could it be anything to do with the new oil or is it just coincidence?
Any ideas?
