Dry Clutch - late engagement

Riding today I noticed that the clutch take up point was at the very end of the lever's travel.  

No clutch slipping, no unusual gear clunking, no problems engaging neutral, only issue is very little lever movement required to disengage clutch..... and late takeup of clutch when letting it out to move off....

Guessing its a sign of something?  Any ideas?

Cheers, Ung.

Adjustable Pazzos, yup.  But nothing changed there.  If I adjust the lever in closer... the same very small difference between engaged/disengaged exists, just happens at a closer in lever position.... if that makes any sense.

It's a common complaint actually.

My 96 does the same thing.

I guess I'd check to see how much total movement of the pressure plate you get...and check for leaks at the slave.

It doesn't take much to disengage a clutch which is why it still works...and why I just leave it alone.

It does make sense, the adjustability of the levers control where they (start to) engage, not over which distance.

To be honest I'm glad someone else noticed this on the M1100 dry clutch (I thought I was the only one).
I did a test ride on one once and noticed it too had this late and short engagement of the clutch.  It's the same with my (wet clutch) M695 and 848, but everyone seems to 'blame' the wet clutch for it. I'm pretty certain it's a design difference in some way, I just don't understand what exactly. Maybe the ratio between master and slave cylinder?

I wonder if the clutch on a D16 or the 1199 have the same 'issue'.

That being said, personally I don't think it's really an issue, just something you need to get used to.

Its not inherent.  I've not needed to be used to it for the 1st 17,000kms of ownership.  Its a new phenomenon as of today - prior to which the clutch took a more progressive lever pull to disengage/engage clutch  :-\.

Pressure plate appears to move just as much as it always did and continues to move out until the lever contacts the handlebar even though the clutch is disengaged way, way before that.  No apparent leaks at the slave....

So other than today it feels different....  since it does actually work fine.... leave it alone and  [Dolph]?

NFI.

I'm thinking that my friction plates are worn.....  the lever moves the pressure plate the same full amount it always did, 'cept the clutch lets go sooner.

The early and short action is a Ducati "feature". Allows quicker shifts [thumbsup]

My only sudden change was after a brutal wash which resulted in water penetration into the rubber just outside the master cylinder. WD40 and oil fixed that.

I'd have a look at the master and maybe the plunger adjuster (if your lever has one)

I have over 30K miles on mine...

The basket is pretty notched up, but works fine.

I did do the groan reduction mod about 20K miles ago.

Clutch get wet lately?

Some of the clutch packs have a 'cone' disc to widen the engagement zone.

Perhaps yours is rusted/stuck/rooted.

I would order up a new clutch pack ASAP.  You will need it eventually, you may need it tomorrow.

Thanks for the replies everybody  [thumbsup]

Nothing appears out of the ordinary.... and the clutch is still doing its work alright, just feels different.  So until the first signs of slipping I'll do nothing....  Just suck it and see.

I really need to fix up our driveway... its fairly steep and has coarse gravel on it which gets very loose when the ground dries out.  Makes getting up the hill on the Monster tricky.... maybe I fried the clutch when slipping it attempting to leave home?  :-[

So anyway, when I'm up for a new clutch pack..... so many options....  I'll be back for more DMF wisdom then :).
