Sounds good Arthur and looks nice. You can recoup some of your outlay now by selling the DP clutch cover, they will be £160 + from Ducati I would imagine. On the Sigma, do they have washers that go under the spring collars to allow you to set what slip you require ? I did buy Matt's DP clutch and it has 10 washers that go under the collars ( 0, 1 OR 2 on each spring), you fit 0 for Maximum slip, 5 for Medium slip and 10 for Minimum slip. From Motorapido, who fitted Matt's, it was set to Medium ( 1 washer per spring ), did not know if Maximum slip (0 washers) would be too much or whether it works the other way on and would need 2 washers per spring.
