Basically Jez you need to start it and ride it more regularly, after all that's what you've bought it for right? Its the only way to get to know the bike and keep it happy, three weeks is a bit of neglect, mind you... I don't know your circumstances...
To cure the wet sump, as its not a good idea to start it like that... Drop the oil into a clean bowl and place back in the oil tank. Then get to know the bike by reading all the excellent info here on the forum. Other than that give me an email and I'll offer you a good price for it.
