From one of my previous posts and the outcome was it worked fine and I'm still using the same setup in my current DD bike
http://www.ducatisportingclub.com/sh...ad.php?t=35525 As for the 620 Class A bike, it suffered from a immense amount of clutch slip at Cadwell as well as a small oil leak from the oil prewssure switch..
Off came the clutch casing, the switch was replaced and then the clutch plates were removed. All looked like new, there was no discolouration of the steel plates and all the friction plates were in a very healthy condition.
So I resorted to the same method of curing the slip as I did with the 750s clutch. Out came two of the stand steel plates and 3 of the standard springs to be replaced with 916 bits which again consisted of one dished steel plate (spring plate) one 2mm steel plate and 3 of the shorter but stiffer clutch springs.
I'll know if its done the trick when I take it out in practice at Pembrey.
