Ducati EVR slipper clutch problem

**LBD** · 23rd July 2009, 03:01

I have fitted an EVR slipper clutch to my Duc....The Slipper clutch function works well as does normal engagement from a stop.

The problem I have is when making a more hurried exit from standing, when the engine is reved higher and the clutch slipped a bit longer, I get a loud chatter which grabs and realeases violently.

The springs are EVR supplied. The plan for now, is to fit heavier springs and maybe a larger slave cylinder to compensate. (No I am not an Armenian arm wrestler with a vice like grip)

Does anyone have any similar experiences they have over come?

Over a week and over 40 views and no solutions....not looking good....

my 996 used to do that when assertively leaving a standstill, and it was bog stock standard.

Cant help much i doubt but whats the setup on those things ie pushrod/worm drive etc?I swapped the 5 bolt clutch on my old S for a 6 bolt one and encountered a few problems which to be honest i would never have thought of.

Have you measured the thickness of the plates, they might be worn? Is it a new clutch or second hand?
Are the plates installed in the right order, there's usually a convex plate at the inside.

I had similar issues with a worn clutch. My surflex slipper is sweet as!

The right order caught me out,never realised the last one in on my old thing was supposed to be off-set a notch.

Also, there usually a small mark on the pressure plate that should line up with a mark on the clutch basket that could be worth to double check.
