Thanks for all your suggestions. I'm convinced it's more at the front than cush drives or chain. I'm not sure what to do about warranty as I've already tried that route with Ducati Leeds who maintain nothing is wrong.
I don't think it is clutch either as mine feels fine and I have the cover slightly proud for ventilation hence being a little noisier! You wouldn't have noticed Martin unless looking closley.
I'm letting a local independant fettler 'Ducati John' have look and he's promised to give it thorough and fast test run this week I hope.
