Help with horrible noise............

Could it be early signs of oil pump failure if that is the case, low oil pressure not getting enough oil into the clutch?

Bike has 41,000 kms. I'm just trying to describe it, I don't know what's making the sound. Oil pump sounds a bit odd, but, who knows. My bad sounds go away once I'm under way though. The whole thing has only developed in the last couple of months.

If oil pressure due to a pump problem was the issue, I'd think the plain bearings in the engine would have said 'goodnight' first.

Agreed.

But how to fix it ? I haven't got a clue !

that is one source.other is through bushing on which clutch hug drives and third is oil dropping from head down by cam chain and getting splashed all over.
sv does not really have problem with oiling clutch.some years of gsxr's do and cure is drilling holes in hub at right places.
curvy sv has issues with clutch plates breaking.

Replacing the clutch is dead easy. You don't even have to drain the oil to do it. It's just the expense of buying a new one.

Mine does it from time to time when very cold... I put it down to the clutch basket, which was showing some notching last time i had it out.

It's 1 1999 curvy with 14K on the clock.

It does need a new chain and sprockets, this came up at the big service at 12K. They said the chain and sprocket will need doing in the next couple thousand miles.

hard to believe you've toasted the clutch in 14k, have you tried adjusting it, not the cable, but the clutch rod ?
