Gearbox noises

[(RIP) Tibs]

Noticed a bit of a rattle/clatter which seems to be coming from the gearbox. It's particularly noticable on the overrun if I blip the throttle.
Any comments or suggestions would be very welcome. (Apart from the obvious: "Take out a mortgage!")
Cheers

Ah, stopped panicing and went and played some more. The noise goes when the clutch is pulled in.
Does this mean its one of those "They all do that, sir." noises from the clutch that i've read about on this very site. And I wonder why I've never been aware of it before....
Feeling slightly less worried at the moment but I expect someone will tell me a clutch horror story just before I go to bed tonight.

Probably worth giving the gearbox oil a change, any visible detritus in there and you can go back to panicking I find that reading ADVrider threads on final drive issues is always good for a few hundred paranoid miles as is leaving my earplugs out for a while.
