Does anyone know what the EVR special springs kit for clutch basket panigale V2 are? The part # is on page 6 of the price list https://www.edovignaracing.com/en/price-catalog-edovignaracing.pdf

Im replacing my OEM slipper clutch with the EVR CTS wet slipper clutch and was debating on whether to upgrade to the new upgraded EVR clutch basket with steel inserts. You can buy it as a whole new clutch basket with new gear part # CDU-WET-Z12-IB. Or send in your old clutch basket and EVR will remove your stock gear from your old clutch basket and install the new style clutch basket with steel inserts part # CDU-WET-Z12-IA. But what are the special spring kit for the clutch basket as an additional option part number CDU-WET-MOL? Are those the springs that would go into the EVR cts clutch? Or is something totally different? Im not saying Im changing my clutch basket but I wanted to know what those special springs were. Scroll down to page six https://www.edovignaracing.com/en/price-catalog-edovignaracing.pdf
 
My answer is less helpful than my thumbs up.

Wish a Ducati insider / master mechanic, as passionate as you would jump on these forums and answer these deep questions
 
Hahah if I knew the answer I wouldnt have posted it. I googled it in every variation I could think of and the only thing that pops up are the springs that go into the evr cts wet slipper clutch. I emailed EVR to explain it to me. Im just debating whether to buy the new clutch basket with steel plate reinforcement and brand new gear. Or send my clutch basket out and have the new style clutch basket installed onto my stock oem gear.
 
Yea whatever happened to the resident master mechanic who joined? Oh well. The EVR basket comes in a couple of different configurations. They are mechanically interchangeable. The six springs in the basket are retained by the drive gear which is retained by 3 steel rivets. The drive gear themselves are stock to the OEM basket. The springs in the EVR basket are from what I was told are of a higher compression value. This is what I believe EVR is referring to by "special springs". I have not verified whether the springs are actually of a different value than the stock springs. As you stated there is a machining process to retrofit of the steel anti-wear pieces which requires you to send in the basket. This, in my opinion, is absolutely not necessary for anything but a competitive bike at a very high level and even then, not needed. I have a 4-year-old EVR basket with more than 10K miles and the compression height of the basket springs are where they should be and the spring pockets have no noticeable wear. I also have a very used EVR sbk Corse basket and the non-reinforced spring pockets are excellent (see photo) As a side note, the Corse EVR setup uses 12 friction plates and 11 steel plates as opposed to the 11 friction and 10 steel on the standard EVR wet application. Clutch pack height is the same at 51mm (I think) however the Corse plates are thinner. The EVR Corse pack also has multiple anti chatter rings in the stack.4966 is a stock 99 basket. 4967 EVR corse. No idea what the six unused holes in the basket are for.

After how many miles would you recommend a wet clutch renew? 650ib’s dry clutch was toast at like 4K miles
 
That question obviously has a lot of variables. If you are so inclined, it is easy to pull the cover and use depth gauge on a set of calipers to measure the stack height with the clutch pack in the bike. If it's in spec, you are theoretically good to go. You could still have a burned plate or a friction disc that has worn abnormally which would potentially warrant a fix even though the stack height is in spec. Also, a warped or non-parallel steel plate can give an erroneous measurement
 
In contrast to the EVR setup, here is the STM dry basket and drive gear.

Thanks for the feedback on this. Regarding sending in a oem clutch basket to get machined with steel inserts is not what they do as explained to me. You send them your clutch basket with gear still attached. And you have the option of buying their old style clutch basket without the steel inserts or buy their new clutch basket with the steel inserts. And then they put your oem gear onto the clutch basket you chose. Unless I misunderstood the email from them. And they install the old style clutch basket onto your oem gear. And if you choose their new style clutch basket they machine the steel inserts into the clutch basket then put your old gear onto their clutch basket
 
Ok thanks for the clarification so you are basically supplying the drive gear and you pick which version of the carrier you want as opposed to just buying the complete unit (carrier and drive plate)
 
I was reading your original post as you already had an EVR basket and was thinking of upgrading to the newer version. My bad
 
Correct. You send them your entire clutch basket with gear. And tell them which clutch basket you want. They remove your old clutch basket and use your old gear and install it onto the clutch basket you want. The one without steel inserts is 320 euros aka $354.58. And the one with steel inserts is 390 euros aka $432.15. The shipping costs to Italy are $66. And shipping back from italy is $73.

The total cost without steel inserts is $493.58
The total cost with steel inserts is $571.25
If you want those springs then add $80 to each total. Total time from the time its sent to getting it back is about 2 weeks. They said they do the work the day they get it. And it takes 6 to 10 days for them to get it

A new clutch basket with gear without the steel inserts is $753.50 + $73 shipping total $826.50. And the one with steel inserts is $797.81 + $73 shipping. Total is 870.81. If you want those springs add $80.

Not sure which route Im going to go in terms of sending it in or buying a new one. But Ive narrowed it down to getting it without the steel inserts. Youre right endodoc. No need for those steel inserts unless youre racing
 
Searched with the prefix: 1199; 1299; and Panigale CLUTCH STACK HEIGHT and the advanced search came back w zero results all 3 times going back all the way to 2012
Searched with no prefix and this thread popped up

What is the total dimension for a brand new oem Panigale clutch pack 11 fibers 10 steels???

Thx
 
Found this but both numbers given seem backwards:

DStyleNZL said:
measure the stack and the clutch springs.

stack ia 50.5 (50.8 min) But plates/pads when measure each are ok
Spring is 44mm (45mm min)

?

.5 < .8

lol

And springs usually get shorter over time, not longer...
 
50.8 min is the EVR spec. The question I have is what are the concave steel rings are for in the clutch pack? The RS EVR clutch I pulled from the SBK motor had 6 of those things in there. It also had more thinner plates in the stack than the OTC EVR stack.
 
I believe they call em anti shudder rings

They are there to promote a lil slip right before full clutch engagement. I usually pitch em but never had a hub n pressure plate that were ramped before. If I pitch em prolly lose the lil bit of slipper effect the oem clutch has

Would someone plz post new oem stack ht
