| REDTREV,Water entering the clutch assembly & left wet when parked will in fact rust the clutch springs , unless you change to the stainless,the steel plates will also start to rust , however you can & should remove the plates for a thorough cleaning & checking out for the steels for warpage as well as the fibers for wear, as well as the clutch basket tang wear , dont forget the P/Plate bearing & grease it ,along with the end of the push rod. ducati has changed the clutch baskets & fibers to a new aluminum alloy & have also tightened up the tolerances with the basket & the plates, this is why your 999 is quiter than the 916 with the stell basket & steel fiber pack. Heat is the the major cause of many dry clutch failures , clutch chatter, plate warpage & so on , to avoid these consequences & not totally eraticate the problem vented & open clutch covers are often used ,some & not allot of P/ plates are also vented to cool down the heart of the matter , in some cases the clutch housing as been machined around the clutch basket area to also alleviate the heat.... is it totally necessary to have all this .. no.. not unless your racing & constantly driving through city traffic where the clutch really heats up.. & starts getting heavy where the machine starts to vibrate in low gear take offs from the clutch chatter.. untill you get going again & she cools down a bit.... slippers are nice indeed, they do help on the tracks & in fast canyon riding to help prevent rear wheel lock up on down hiftinf , but unless your really putting her through the paces , you really dont need it, the stock unit when maintained periodically will more than suffice . later..
