Likeliest to be problems with the slave cylinder seal leaking/loss of fluid. This is a weakness that Ducatis tend to suffer. I got over it by remaking the slave cylinder piston, push rod and using different seals so that the side of the cylinder that picks up all the crap off the chain is sealed wioth an air vent pipe up under the seat. Used this on my ST2 to test it and its stood up to 25,000 miles withjout a hitch. |
