Clutch arm moving up?

[gixersix]

My clutch arm seems to be working it's way out of the engine. See photos - check out the spring, which used to be quite "compressed". Any ideas? Have I got to remove clutch cover to sort this? Engine is also making occasional click whilst ticking over but I'm having a hard time tracing this and wonder if they might be related. Bike has done 30,000 miles.
