Title: Clutch Quiet Mod Post by: koko64 on March 29, 2013, 02:15:05 AM Tried the clutch quiet mod that's about. You know the one when you place a friction plate in first under the clutch pack. There have been qute a few threads and links about it.
Very quiet, no clutch noise at all. Just the jingle with the lever pulled. I felt uneasy about the side load on the clutch basket bearing. Maybe this solution was never considered oem for that reason (some have suggested Ducati likes the trade in clutch parts). I changed it back to a compromise mod which I have used before which is nearly as quiet but not silent. I am running an alloy basket, Vee Two alloy hub and Barnett plates. I got my oem and aftermarket clutch plates out of my spares and selected a steel friction plate with the largest tangs for a tight fit and put that in last before the last driven steel plate. I also considered bending the tangs inward a little to act as a spring preload. Some have used an extra dished "spring" driven steel plate instead of a flat one for a similar effect of preloading the pack to cut down the noise. Preloading the clutch pack appears to be the way to stop the noise, but which way is safest? What solutions have others tried? Any thoughts on what type of loads are acceptable to the bearings involved? Title: Re: Clutch Quiet Mod Post by: Raux on March 29, 2013, 02:21:20 AM check out that $2k clutch that DuckStew mentioned
Title: Re: Clutch Quiet Mod Post by: koko64 on March 29, 2013, 02:26:13 AM Yeah I saw that. :o$$$
Be good if that guy sponsors him and he can give us a report. Title: Re: Clutch Quiet Mod Post by: Raux on March 29, 2013, 03:40:18 AM Yeah I saw that. :o$$$ Be good if that guy sponsors him and he can give us a report. he said no Title: Re: Clutch Quiet Mod Post by: koko64 on March 29, 2013, 04:18:36 AM Another solution I havent tried is substituting another dished plate to replace the driven plate at the front of the stack to add some spring preload to the pack.
Anyone tested this? Title: Re: Clutch Quiet Mod Post by: ducpainter on March 29, 2013, 07:16:15 AM Another solution I havent tried is substituting another dished plate to replace the driven plate at the front of the stack to add some spring preload to the pack. I added a dished plate when I cleaned up my plates to eliminate the groan. put it in the stack facing the opposite way of the factory dished plate and used the entire stack. Worked great. Anyone tested this? There is so much play between the tabs and the basket now that the clutch is louder than the exhaust at idle. :P Title: Re: Clutch Quiet Mod Post by: koko64 on March 29, 2013, 07:39:10 AM Yeah mine got like that, clutch louder than pipes. I've got a closed clutch cover and it still shits me.
Title: Re: Clutch Quiet Mod Post by: ducpainter on March 29, 2013, 08:14:58 AM I have an open billet cover thanks to my last crash... :P
LOUD. Title: Re: Clutch Quiet Mod Post by: Triple J on March 29, 2013, 10:22:23 AM What solutions have others tried? Any thoughts on what type of loads are acceptable to the bearings involved? I think I'm the one that originally started the quiet mod thread (to much ridicule [laugh])...probably on the old board, but maybe this one. Anyway, I ran my MTS that way for about 20K miles of mainly commuting...same clutch. I've also read of ST guys (where the mod originated) going much longer. I don't think the bearing loads are an issue. Title: Re: Clutch Quiet Mod Post by: geoffduc on March 29, 2013, 10:26:04 AM EVR make what they call an anti-clank pressure plate, it comes in a combination of two colours with a very neat centre piece which is also anodised.
I have one fitted on my streetfighter, the noise is slightly less than with DP plate but the take off is alot smoother and selecting neutral is perfect!! Geoff... [coffee] Title: Re: Clutch Quiet Mod Post by: koko64 on March 30, 2013, 03:19:32 AM I got a " dished"plate out of my spares and replaced the last driven, steel plate. I pointed the curved plate at the pack so the pressure plate sqeezes the curved plate onto the clutch pack. Made it a little quieter again. Not bad, and no end load on the basket support bearing.
So last driven steel is another dished, curved plate, and last friction plate is a big tanged steel plate. Very quiet, less noise than the FCRs slides "clicking". I put this set up on a pack of otherwise normal Barnett plates. The friction material is barely worn, but the Barnett tangs have shrunk nearly 2mm in 6000 miles(10000 kms). The alloy must be soft. I tried to preload the pack with the extra curved plate up front while the fat tanged friction plate is locking the pack in place. Less vibration and noise at low speed/lower gears and more feel to clutch engagement. Now to see how long it stays quiet..

[coffee] Geoff, it sounds like the EVR plate has some kind of dished steel plate attached to the pressure plate to preload the pack. Is that right? Title: Re: Clutch Quiet Mod Post by: geoffduc on March 30, 2013, 10:15:26 AM Geoff, it sounds like the EVR plate has some kind of dished steel plate attached to the pressure plate to preload the pack. Is that right? Yes it has a dished spring steel plate on the back of the coloured pressure plate which takes the place of the last steel clutch plate, other wise it's just a straight forward swop. I spoke with a guy from EVR at the 2011 Milan bike show who talked me through how it works so when I got back home I ordered one from www.speedycom.co.uk (http://), when it arrived I fitted it without any problems and its worked perfectly and like I've already said finding neutral is trouble free...

I don't think the bearing loads are an issue. That is correct, Triple J. I continue to run your mod on my 1100S, but I think I need to refresh the friction plate - it has gotten smooth and allows a little slippage now and them. Nothing like the self-destruct noise of the stock installation, but still not was quiet as it used to be. Title: Re: Clutch Quiet Mod Post by: Billyzoom on April 12, 2013, 01:35:03 PM I don't know anything about the side loads or any other issues. It was a great mod for me...been running it for quite some time with zero issues. Free, significant improvement. If it causes an issue down the road I'll deal with it then. It gives me a lot more enjoyment, and it's FREE. FREE I SAY!!!!!!!!
MWAHAHAHAHAHAHAHAHAHAHAHAHAHAHA!!! Title: Re: Clutch Quiet Mod Post by: Raux on April 12, 2013, 01:50:54 PM you guys and quiet clutches... get a wetclutch bike and get over it ;D
I WISH my 696 had that clackyclack of the ST2 Title: Re: Clutch Quiet Mod Post by: koko64 on April 12, 2013, 04:29:15 PM [laugh]
Mine still makes noises that lets its existence be known (to those who can identify that stuff), but I can hear my pipes now, and they are Termis. Love the dry clutch. Favorite clutch of any bike to work on. [thumbsup] They can look destroyed and somehow still work fine [thumbsup] You can take the cover off and teach your kids clutch operation 101 [thumbsup] Before you got into Ducatis, have you ever seen people worship a clutch as a mechanical thing of beauty like that? [thumbsup] The pressure plate has inspired art [thumbsup] Its a sect within a sect.

It still looks amazing, has a little bit of the rattle, but I hear my Arrows more. Perfect. Title: Re: Clutch Quiet Mod Post by: koko64 on April 17, 2013, 03:22:13 AM I wonder if the new spec Barnett plates will be quieter, Brad says they've been out for awhile.
www.barnettclutches.com/news/news_detail.aspx?news_d=74 (http://) They have replaced the wave/curved plate with a "damper spring". Anyone tried these yet? Title: Re: Clutch Quiet Mod Post by: memper on April 17, 2013, 06:31:53 AM you guys and quiet clutches... get a wetclutch bike and get over it ;D Can't you remove the noise damper inside the cover? Might make it a tad louder..I WISH my 696 had that clackyclack of the ST2 Title: Re: Clutch Quiet Mod Post by: Raux on April 17, 2013, 06:33:41 AM Ultimately i want open dry clutch goodness
the st2 is the tourer and rain so i won't open that Title: Re: Clutch Quiet Mod Post by: Speeddog on April 17, 2013, 10:09:54 AM I wonder if the new spec Barnett plates will be quieter, Brad says they've been out for awhile. www.barnettclutches.com/news/news_detail.aspx?news_d=74 (http://) (http://) (http://) They have replaced the wave/curved plate with a "damper spring". Anyone tried these yet? I fitted one to a mid-90's 900SS a month or two ago. With that new thick inner steel, the stack height was a bit much. The outermost friction was so high in the basket that it looked like it could slip out when the lever was pulled. Swapped to the standard '2-steel' setup. Not sure if that was peculiar to that SS or representative of typical fitment. I'm not very happy with brand-new parts if I have to fiddle around to fit them.... Title: Re: Clutch Quiet Mod Post by: Triple J on April 17, 2013, 12:17:18 PM the st2 is the tourer and rain so i won't open that Why? I commuted on my Multi with an open clutch (quiet modified ;)) for quite a while. It saw more rain than a bike should be subjected to, and the clutch was never a problem. It did sit in a garage at night, but during the day it sat out in the rain. The clutch plates will stick a bit overnight, but free up as soon as you turn it over.
