Have Fitted a Yoyodyne slipper to 996 BP, purchased original Ducati sintered plates. But get bad noise when a standing start, have tried putting original(no sintered) clutch plate next to spacer closest to pressure plate thinking its this, but no luck.
When riding all ok.

Am I better off using non sintered plates?, normal road riding.

Any suggestions?

[cmoss]

Thanks, but don't understand why. At launch it should act as normal clutch only on down shift should it open up.

i've got an stm one and dont believe it sounds any different to a standard one.

Could some one post their clutch plate set-up. Including type of plates and spacers used.
I've tried using dish plates and tried without, just spacer plates, still same.

Sounds like your plate stack height needs adjustment. It should sound just like the standard clutch when setting off.

I've got the single progressive spring STM clutch and I think it's quieter.

In fact several other DSC members have remarked on how quiet it is.

I think (if I remember rightly from the conversation with the very more technically mined chap...) that it's the plates aligning themselves as they catch and hitting the basket that causes the screeching noise.

Maybe it just needs some WD40 in there?

[mike916]

Yeah and then some three bond after to stop the slipping

Don't forgot to put some on the brake discs too - more than doubles their life

Check the plates.
There is a "dot" on them.
This should always face outwards.
This is most likely the problem.
Also check the correct the height of the stack with the manual.
If you're not correct, the clutch will slip, it's partly your use of the clutch / your method.
Get hold of a verner caliper, and make sure the depth is correct.
This is imperative.
If it's slipping a lot on departure, what can happen is that the clutch will eventuall collapse inwardly as you're placing too much pressure on the pressure plate, which, in time, will fracture - the voice of experience speaking here!

Then you'd best be with the AA!
