[Ducati] New guy needs Clutch Help

Sun Jun 4 16:09:48 EDT 2006

I do not think you need a slipper clutch, esp for typical street bike you do not plan on racing. I rode a 1995 916 for many years without and have done many track sessions without. Of course you can not slam down 2-3 gears and not expect some tail action...but who does that on the street anyway? Slippers can be a bit more complicated, and have more parts to wear and some have metal to metal ramps while others use balls and ramps so some design differences to consider related to price and expected lifespan. My 996R has a slipper but I bought the bike lightly used with low miles from someone with very deep pockets, money was less of an object for previous owner.  My 1995 916 I had a Nichols basket, stock hub and Barnett clutch plates and was quite happy with the arrangement. This lightenend up that side of crank about 4 pounds. If I had gone with billet hub maybe another pound or so. 
  Slippers are the latest gee gaw gott have it item, kind of like radial calipers, are they better, maybe in limited cases, a must have, hardly. 
  I think even in the conventional non slipper you have some options to consider. I think upgrading to 48 teeth versus 12 tab is an improvement, spreading out the load over more than the typical 12 tabs is good. Seems lots of options in 48 tooth also. Course that will limit your clutch plate options as there are plenty of 12 tab palte options but fewer 48 tooth. I would stick with standard spring as well, for simplicity and tunability. Not uncommon to change pressure plate feel by alternating hard and softer springs.
   So look at Barnett, STM, Yoyodyne, Nichols,  etc for ideas. Rich

  What about updating to the newer slipper clutches I hear newer Ducati's come 
with standard (the multistrada comes to mind) Is that a direct replacement? 
Do I need a slipper clutch?

No, removing clutch not that difficult,, the hardest part of removing clutch 
is the basket, I usually use a pneumatic impact for that. Baskets get 
notches as well as hub so at some point you do need to replace the entire 
package, basket, hub and all steel and friction plates. There are a ton of 
good options there depending on your budget. Barnett makes baskets, Nichols 
makes baskets, etc etc. Still the stock steel basket is not expensive. So 
going back with stock parts is not really a bad idea esp in terms of costs, 
I know surprising considering they are Ducati Parts. But a new aftermarket 
basket will run you more, in some cases twice as much as stock. I think you 
might be able to get an entirely new package for 600-800 depending on what 
you want, that being a standard 12 tab non slipper with conventional 
pressure plate and springs. Yoyodyne is a good palce to start looking but 
not the only ones. There are bunches of options.

This is what I did.
I took the slave off and it looks ok, although there is a little rubber boot
near the front sprocket that was ripped, I am hoping the amount of grit that
was in there was not the problem. I pulled the rod out and it appears fine
as well. While I was at it I took the clutch lever and master cylinder off
and replaced them with a Brembo "gold" master with remote reservoir off a
748, I thought I had all the pieces but my lever doesn't have the plunger
or the retaining bolt. I am looking for those pieces, If I cannot find them
I will put my regular square black master back on, bleed the clutch and try
it again. I am hoping I do not need a new clutch basket as my mechanic
thinks may be the problem. I have never removed my clutch, Is that
difficult?
Thanks for the help.
Michael

Michael did you get my direct response and try any of those things i
suggested. Rich husband of Maxine from the Hawk list. :)

New guy to this list, Friends of mine on the Hawk list told me about it.

I have a 1992 900ss

Long story as short as I can.

I recently had a really hard lever pull with the clutch, 1st pull was kinda
hard, 2nd was worse and 3rd nearly inpossible, then the bike never fully
went out of gear, limped it home (this was after a day of riding and
noticing some clutch slip , I would get on the gas and it would pull hen all
of a sudden full go into gear)
I was't sure what it was, took the clutch cover off and all looks good,
opened up the master resivoir and the fluid is black and looked a little
low. Took the slave cylinder off and there was some gunk in there, seems
the little rubber boot keeping grease and grime off the bar was ripped. So
I am thinking there was some dirt stopping the cylinder from pushing the
rod.
I want to replace the slave cylinder, can I use one from a 748/916? What
does everyone reccomned?
While I am at it I have a remote resevior and lever from a 748 that I want
to put on, I need the bolt and plunger for the lever, Anyone know where I
might get one? Anyone got something for sale? Also I have to replace that
rubber boot near the slave cylinder, where might I get one of those (my
local dealer is useless and would take weeks to get me parts at high prices,
ebay is good but I can't find what I am looking for and I have my first
trackday in 3 weeks!)

Thanks in advance, Michael
