Re: [DucatiST] Re: Shiny New Clutch

 

Look at it this way...are you in the top .01% of the racing elite where the few ounces will make the difference between winning and losing? Do you enjoy cutting up a clutch due to the fact that the heat cycles of your clutch had grabbed the alluminum screws and they do not want to back off now? Do you like the lump in your stomach you get when the hex tool spins inside the allen socket of the bolt?
 
If you answered yes to the above, then go for the weak cheap aluminum allen bolts for your clutch. (You might want to grind back the used end of the hex to a fresher unrounded section so you can postpone the inevitable).
 
Me? I go stainless or if you need the weight savings on an ST platformed bike, go for titanium. Do use an anti-sieze of somekind when you do. I keep moly paste in a squeeze tube that is used on shotgun's choke tubes as a handy anti-sieze on the bolts and the "top hat" and the bearing in the pressure plate.

Does anyone know if the OEM Fasteners Steel? Would aluminum bolts for the spring retainers be a decent choice? (Still going to get some anti-seize on there).
