First off, I love the look of the 07 s4r dry clutch. I'm still wanting to keep it exposed, but I'm about to get the boomtubes on my bike... and I have been thinking of trying to set up my bike with a clutch set up that is a little bit less clank clank clank at idle... I have no clue if this is even possible without covering up the entire clutch... does anyone know or have any recommendations? Again I want to leave the clutch exposed.. I saw the EVR Ducati Progressive Engagement Clutch Pressure Plate will this accomplish this?
Ear plugs are the answer.
I have the EVR pressure plate that claims to reduce noise. It doesn't.
I can't say how effective this is:

Meh, I'd put the stock clutch cover back on. Me personally, the sound adds to the rumble of the twin. If I just want the rumble, I'll pull up by a Harley and kill the enginen.
I swapped to an aluminum basket a while back and it took away a lot of the noise. The stock basket rang like a bell when I tapped it with a wrench after I had it out. The AL one just went *plink*
Plates that fit snugly in the basket helps too - reduces their ability to jingle about
I tried this on my S2R1000 that had an EXCESSIVE clutch clank. It worked fine. Still the sound of a dry clutch just much tamer...

The EVR pressure plate is not designed to reduce clutch noise at idle. It offers a more progressive engagement when going from a stop to moving, which eliminates the "crunching sound" (for lack of a better word) you sometimes hear at that point. It does nothing to reduce the noise of the clutch plates hitting the basket, nor does EVR claim it to.
The more worn the plates and basket get the louder it will get. I suggest going with a 48T setup when it is time to replace. The tolerance is tighter and stays tighter much longer than the 12T and the noise is much less. It will also last you more miles than the 12T setup so that is good.

Remove your clutch pack. Take the outer most friction plate and put it back in 1st (before the 2 steel plates), then re-build the rest of the clutch pack in the same order it came out. You'll have a quiet dry clutch even with an open cover, it's free, and it'll take about 15-20 minutes. [thumbsup]
It'll be almost silent with the bike in neutral (no more clack-a-clack-a-clack)...but will still have the "scraping" sound when the bike's in gear with the clutch pulled in.
This set-up should make your clutch last longer too since the plates aren't trying to beat the basket into submission with every pulse of the motor.

how much longer does it last? i only got about 11k avg per a pack using OEM plates. i need a new basket and friction plates.. what kind of cost are we looking at here.
How long it lasts is up to the rider. I've seen them toast after only 3,000 miles, but also other packs have gone over 20,000. The sintered packs range from $479 to $509 (http://www.mota-lab.com/evr-ducati-48t-aluminum-clutch-basket-and-complete-sintered-plate-set-p-354.html (http://www.mota-lab.com/evr-ducati-48t-aluminum-clutch-basket-and-complete-sintered-plate-set-p-354.html)). EVR will be releasing organic based plates in a month or so that are significantly lighter than the sintered kits, made of the same material as stock and cost about half as much as the sintered packs. It will use the same basket as the current kits do.
This works great. I did it a couple months ago and I was very surprised. It made a significant difference, and I was able to do it myself in 20 minutes. Not bad, considering I'd never touched a clutch and was a little apprehensive.
In terms of noise at idle, if the stock rattle was a 100 in terms of noise, it probably dropped to a 30 or 35. It was very significant and still keeps the character of the clutch sound.
Do it....don't need to spend any cash!

is there going to be a significant difference in wear between organic and sintered material?
half the cost around $250-300ish? for just the pack? or as a combo pack/basket?
seems like its worth giving it a try as the rattle is getting annoying on my bike.
