Clutch Quiet Mod

[koko64]

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?

check out that $2k clutch that DuckStew mentioned

Yeah I saw that. $$$
Be good if that guy sponsors him and he can give us a report.

he said no

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?

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.

There is so much play between the tabs and the basket now that the clutch is louder than the exhaust at idle.

Yeah mine got like that, clutch louder than pipes. I've got a closed clutch cover and it still shits me.

I have an open billet cover thanks to my last crash...

LOUD.

I think I'm the one that originally started the quiet mod thread (to much ridicule  )...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.

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!!

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..

When I was younger, I thought the loud clutch was cool, now I hate it. I love the dry clutch otherwise.

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, when it arrived I fitted it without any problems and its worked perfectly and like I've already said finding neutral is trouble free...
