K...I have a 3 "belt drive on my shovel..If you've ever tried this setup w/ the stock or 5 finger clutch you know its difficult if not impossible to keep the clutch basket from "walking out" while the clutch is pulled in..So after living with it for a few seasons i decided to up grade the clutch..2 options I was considering were Rivera...and Barnett Scorpion..both made for Shovel/Pans..I heard from a friend the Pro Clutch worked great..but was a "little noisy". I bought it..it wasnt cheap ..like 550$ . Installed easily and works PERFECTLY..BUT..this clutch rattles like a MF.. You can hear it from miles away..I didn't think it would be an "issue"..my bike is fairly loud w/ the pipes, how loud could it be?..Well put it this way..if you took an empty spray paint can and attached it to the clutch w/ the ball bouncing around inside the can..thats pretty close..And its the kinda noise that hits you the wrong way..riding/ stopped/ engaged/ disengaged...noise!... when you pull into a parking lot or bar w/ other bikes in it everyone will turn and say WTF is that? Is there something wrong there? BUT as I said it works PERFECTLY..Just a heads up to someone considering this "upgrade".It bugs me so much I am considering swapping for the Barnett.

So, you are complaining that the clutch on your chopper is too loud.

..its got a certain frequency that drives me insane..thought I might let others in on it..May not be an issue for some..I for one dont like hearing a rattle can shaking in my ear constantly while I am riding..It annoys the fuck out of me.. Maybe I shouldn't have posted this..I'm not looking for a beating here.

I thought loud clutches saved lives?

I have a dry clutch Ducati, open cover, though the sound is probably different from what you're getting, but it's still loud and distinctive.

I dig the mechanical racket, some people don't. To some it sounds "broken"...

sugarlou

08-01-2007, 09:45 PM

It sounds broken alright....and it makes the bike stand out from the sea of Evo's..but i would rather hear the mill than the clutch rattle. JUST ME...Tom when I get some scratch for the swap I'll give you a great deal on it. Anyone run the Barnett Scorpion????

Guys who know more will chime in here, but if it's THAT loud, something may be f'ed up, you know?
They should be noisy, but what you're describing sounds pretty horrendous.

The Scorpion clutch is louder.......

sugarlou

08-01-2007, 09:56 PM

I am a musician and a bit nutty when it comes to noises...Ive got "ears" so to speak and certain things get to me. It's installed correctly and works fine as I said..but its LOUD..I called the company and their guy said.."yup" when asked if it was supposed to sound like that..If anyones considering this clutch and feels it may be an issue for them as well..GIVE ME A CALL..I let it run over the phone..Clack clack clack...Also note that this is an OPEN PRIMARY. Hey Chicago, you running open belts as well or primary covers?

sugarlou

08-01-2007, 09:58 PM

Does the Scorpion quiet up while you are riding..or make noise all the time? I understand it should make noise while the lever is pulled in and the tension is off the plates but when riding it should shut the fuck up like the stocker..no?

I wouldn't say Hyper sensitive..other people hear it too, its not like its just me..I am not the first to complain about the noise..The guy who said it was a "little noisy" was a local shop owner who I bought the clutch from. He told me another customer who he sold the same clutch to had him remove it due to noise. Trent I RESPECT your opinion..you build awsome stuff but I am not saying ITS NOT A GOOD CLUTCH. I am saying FOR ME it's fucking annoying and may be to others as well..just a heads up man.

In terms of making a big twin a comfortable daily rider, I think a pro clutch is the absolute number one thing to do. No more hand cramps in traffic.

They definitely clatter, but the BDL I used to use was the same or worse.

It was no doubt a gigantic improvement over the stock clutch as far as performance is concerned..feels way better...no creeping

Dr. Jett

08-01-2007, 10:27 PM

I don't get it? The only time a dry clutch should rattle is when it is dis-engaged (pedal/lever depressed). Are you saying the thing rattle-chingles even when you are in gear?

I mean every open primary I ever had with just about any brand of clutch rattles when the lever is depressed due to the steel plates clanking around in the clutch basket and being loosely dragged by the friction plates, but damn, I never leave the clutch depressed for any period except for departing a stop, or changing gears, and that lasts only a few seconds.

I actually love the sound of a loud clutch rattle, but is sounds like you are saying it does it while in gear.

There must be something wrong with the setup or installation on your bike.

choppercopper1

08-01-2007, 10:27 PM

I have two of them. One on the 49 and one on the 57. They do make a racket. The guys at the shop say they know when I am comming from the sound of the clutch. It don't bother me. If you really want to make it loud try drilling holes in the basket. The noise is even louder. Best clutch I have ever run.

It makes the same sound w/ the clutch in or out and the rep says "yup" when asked if this is normal..I don't see why or how ..but it does..

Dr. Jett

08-01-2007, 10:41 PM

It makes the same sound w/ the clutch in or out and the rep says "yup" when asked if this is normal..I don't see why or how ..but it does..

That I don't understand that, in gear. If the drive dogs of the metal plates are engaged against the drive blocks inside of the clutch basket, and the friction material plates are clamped down on the metal plates, what the hell could be rattling? Sounds strange.

caschnd1

08-01-2007, 11:55 PM

Yeah.... I'd agree with Dr Jett. The clutch shouldn't make any noise running down the road. Somethings not right.

I also find the sound of a dry clutch (when disengaged) in a belt drive to be very annoying. Affects me like finger nails on a chalk board. :eek:

I found a different solution to that problem though. I installed a SuperMax SilentDrive primary belt drive. This thing is made out of polyurethane and is tough as nails. And the polyurethane clutch basket won't pass the noise of the clutch the way aluminum clutch baskets do. It's as quiet as a wet clutch now. I was skeptical about the toughness of polyurethane pullies, but after 30K miles they still look like new. No signs of wear on the teeth. I run mine under a tin primary cover.

http://www.clubchopper.com/photopost/data/500/medium/DCP_22181.JPG

In the original message you said that you swapped the clutch because the clutch basket was walking out. This is actually a indication that the engine output shaft and transmission input shaft are not aligned. With primary chains the alignment is not as critical as with belt primaries. If you get the engine and transmission aligned, the clutch basket won't walk out. There are also two relatively inexpensive band-aid fixes for this problem. One is called the Ram Jett Retainer (about $15) and the other is called the Clutch Tamer (about $50). Both will keep the clutch basket from walking out, but do not address the alignment issue.

try some of the stock steel plates with the spring loaded ball bearing.that'll quiet it down some.

76shuvlinoff

08-02-2007, 05:35 AM

I was always told they are loud when ran open but I run one in a closed chain drive primary on my shovel and hear nothing, never going back!

sugarlou

08-02-2007, 06:16 AM

The stock cluth couldnt handle the outward pressure of the 3"belt....The motor sprocket and clutch basket were dead nuts using a piece of glass as a straight edge. I installed the "tamer" as well...It worked ...but barely and if you got caught in traffic it got real "cranky"..I knew there was a better way..To try and finalize this post: The Proclutch works great...and makes alot of noise engaged or dissengaged...AND according to Rivera thats NORMAL. Theres nothing"wrong there". if the metal plates arent engaged agianst the dogs the bike would not move..I cant say whats causing the noise..perhaps Rivera can. Also theres obviously other people who hear this rattling...some care/ some don't..Thats the point i am trying to make.

Trent

08-02-2007, 07:48 AM

No worries, I didnt take your post as any sort of disrespect..

I do think something is wrong, as I said I run those exclusively .. they dont make noise going down the road, but at a stop light you will get some clatter.

Dont give up on that clutch.. all the other aftermarket clutches make the same or MORE noise.

Kuda

08-02-2007, 08:45 AM

+1 for the Supermax belt set up, I run the 2 1/4" open Preditor and it's dead quiet, plus a stray rock won't break the 14mm toothed belt. Mind you, I also run a stock 3 finger clutch, but as everyone said, it should NOT make much if any noise when it's engaged. Something's not right there for sure. Have you tried the stock anti-rattle flats yet? Those would be the little sprung ball affairs that lock onto the dogs...

I have to agree here as well. I bought a Rivera from Trent and got it on about a month ago. I don't think it's any noiser than the stock clutch (not noisy at all). I have to also agree with the majority here and say that there's got to be another issue here. Not questioning your wrenching ability at all but if it was me I'd probably take it off and inspect it thoroughly and re-install it.

sugarlou

I thank everyone for the input..I appreciate all..I believe its installed correctlyalthough I am starting to doubt the mating up the Karata basket and dogs to the Rivera steels..They look quite different in size..The Karata dogs are skinny compared to the slots in the steels..
It is normal for the slots in the steel plates to be wider than the dogs in the clutch basket on most of the 4 speed setups I have seen. You just want to make sure you have the clutch pack set up correctly where the steel plates are not the first or last in place on the clutch pack.

HOLY FUCKING SHIT!!!! Thats sounds like garbage! I agree with you dude, that is horrible and does sound just like a can of paint. When the tone changed a bit towards the end, was that you pulling the clutch lever? I'm thinking you need to get that thing off and do a little troubleshooting. Good luck with it, and when you find the demons, post again to fill us in. I'm sure it would be helpful to those interested in installing one on their own scoot.

08-02-2007, 05:18 PM

Somethings wrong..but the fucker works perfectly so ..I called 'em..they said the noise was normal...It comes apart this weekend.I'll take pics..Yes ,The change in tone was the lever being pulled in.

sugarlou

08-04-2007, 02:38 PM

As per suggested..I took my Pro Clutch apart for inspection today..I was complaining of what I felt to be "excessive noise" in my last thread. The ONLY thing I found to be suspect were the condition of the Karata pully/basket's "dogs"..They need to be replaced..Will that bring the rattle can noise down?...maybe .maybe a little.....maybe not... I was able to run the bike without any clutch friction/steels in the basket and it made no noise.This eliminates the clutch basket and motor pully and belt... The clucth makes the same rattling when you are riding..but decreases substantially when you let off and "coast". Almost no noise when you pull out in first ...some at second and plenty when you are in third doing around town speeds. I really wanted to find the"demonds" ...but no luck..The baskets bearing runs smooth ..the basket does not wobble in any way..the motor pully is tight. The clutch hub was tight (60ft lbs)and spun smoothy and true with no wobble.. I repacked the plates as per the instructions..used the supplied washers to add a little more spring tension...locked the tabs http://i203.photobucket.com/albums/aa142/lickysixx/baddog.jpg[/IMG]down..and fired it up to the same rattle it had before I started..Any suggestions?

Dr. Jett

08-04-2007, 02:51 PM

I don't use Riviera pro clutch, so excuse me if I'm off base here, but why is the distance between the clutch steel plate to friction plate different than the distance between the last friction plate and the basket drive face???? Sould they not be the same??? See arrows:

http://i43.photobucket.com/albums/e352/dean350b/baddog.jpg

sugarlou

08-04-2007, 02:59 PM

the first steel is a fatty..the rest are thinner..why? Dont know

Dr. Jett

08-04-2007, 03:01 PM

Lou,
It appears you are driving the transmission and final drive by the outer pressure plate clamping somewhat down on the steel plates, and the steel plates are driving the basket via the steel basket dogs.

In reality, the steel basket dogs are just there to keep the steel plates aligned and to somewhat engage the clutch, but the true clamp-up of the clutch should be the pressure plate clamps everything down against the rear (inside) drive face of the basket.

I see friction scratches on the basket drive face, but maybe that is from the last clutch you had in there.

Maybe your Ramjet isnt installed correctly allowing the basket o be pushed back towards the transmission, or something is stopping the clutch pack from seating on the basket drive face.

You steel drive dogs tell a story that they are taking all the drive load from the steel plates.

My. 02

sugarlou

08-04-2007, 03:13 PM

This clutch is "special"..the stocker has steels w/slots on the ends and frictions w/ no slots...this clutch has slots on the ends of the frictions and none on the steels. Its the opposite..I am not sure how that applys but...it works great.

I was told by a local shop owner that the dogs were indeed worn but that it was "normal"... any clutch will do that to the dogs over time ..no? Why then are they removable/serviceable?

08-04-2007, 04:35 PM

it would be hell to machine a clutch basket and have them NOT be a seperate part.

08-04-2007, 04:40 PM

good point

bustedlifter

08-04-2007, 08:08 PM

What he said. Your noise is the plates hammering into the dogs. They should NOT look like that, but they do because the plates are transmitting power throught them. For whatwever reason, the clutch isn't clamping enough.

I'm willing to bet those dogs are worn from the old clutch. I run a pro clutch and there's no slipping no matter how much you grab the throttle. As far as wear,it's a lot easier on parts than the stock set-up. They make some noise but the trade-off is a clutch that works flawlessly.

tom

08-04-2007, 08:42 PM

sugarlou- if you decide to replace it I have a 3" pulley I'm not using, you can have it cheap. send a pm if interested.

sugarlou

08-05-2007, 07:24 AM

I would say the marks are from the Pro clutch..the spacing is much to close to be the last clutch..(stock style). It would seem the pack is not tighteneng up enough as stated earlier by the DR.J. Although there really isn't any adjustment ...just washers..which Ive installed already..same noise..It may be the worn dogs..but for now I am sticking to my original post..this clutch/basket combo makes big noise. Ive contacted Primo..let see their responce..I'll post it once it arrives.

laid55

08-05-2007, 09:57 AM

the first steel is a fatty..the rest are thinner..why? Dont knowWhat's up Lou?the reason the first is a fatty is because that is now the main contact surface.the clutches no longer use the surface of the clutch basket as the contact surface.if I'm not mistaken,that fat disc bottoms out on a lip on the clutch hub a cunt hair before it touches the basket.the reason is,there's now a bearing pressed between the hub and basket that wouldn't take the side load pressure.so,unlike the old style clutch set up,the rivera actually relys solely on the dogs to connect the hub and basket,through the clutches.that being said,I'm sure if you replace the dogs,it will get quieter.also,i noticed you said you were running a basket that wasn't a rivera .is it possible that the dogs are a little thinner to begin with,than rivera's?just a thought.I've ran these clutches before on a coule of bikes,and I can only say good things about them.I've never had them make that much noise before while engaged,but they do make a little.the only place that noise could be coming from is between the dogs and the clutches.so concentrate there.check the tolerances.I live about 10 minutes from rivera.if I can help you out in any way,let me know.John,the owner,is real cool and helpful.I've dealt with him plenty of times.and the chicks that work there are fuckin' HOT!anyhow,don't get discouraged,it's an easy fix.

08-05-2007, 10:25 AM

Thanks Laid..its really come down to the dogs it seems..Also I am sure Rivera is not happy I am running a Karata Belt drive! I have attempted to contact Rivera..sent them a link to my little youtube Vid of the bike running. It makes sense now that you've explained the deal w/ the thick steel going in first to eliminate the basket back wall..and as stated the clutch works great..I have logged lots of completely trouble free miles..The dogs may be different than the primo's ..That was my earlier assumption. Either way it sounds like a grenade went off in there. (to me)

Hi, From the video you sent, it sounds like normal noise that you getfrom an open belt drive. However, as the clutch p[lates start to wear, andthe gap between the edge of the friction and the clutch dog grows, the drivewill become noisier. Usually replacing the plates will help to quiet that abit.Thank you,Ben KudonDirector of Sales & MarketingRivera Primo Inc.</PRE>
THIS CLUTCH SOUNDED EXACTLY LIKE THIS WHEN I FIRST INSTALLED IT..maybe a tad quieter.</PRE>

this clutch is backwards though( so to speak )..the stocker has the notches on the steels..this has the notches in the frictions..so they aren't interchangable

Update as of 12/5/07

O.K heres the original video link
http://www.youtube.com/watch?v=_xBaZJQiAyE

Its fucking freezing/ snowing here in NJ and the Shovel is a bit cranky about starting so no follow up video yet.

Heres the deal: A cat named satanmechanic saw my youtube video and had the same issues w/ his Proclutch.. we corresponded back and forth a few times and he relpy's " I fixed it". All of the credit goes to him..not only did he help me out..HE MODIFIED SOME OF HIS OWN PARTS AND SHIPPED THEM TO ME FREE.

Its great to know there are still some real people left in this world and that good Karma comes back around!. I of course am gonna take care of him for his troubles and let his wife pick out something from my website.

Anyway heres the deal.
I am not "super wrench" (obviously) so bear with me on some of these terms.
The rivera clutch hub has splines..The first clutch steel to go in is .120" thick steel plate. It stops on the hub (due to a widening of the hub) before it touches the clutch basket. This space behind the first steel is responsible for the clutch pack never truely tightening up to the point where the plates stop rattling. Why its designed like this I don't know.

I measured the distance behind the first steel and the satanicmechanic modified a stock HD steel plate as well as an additional Rivera friction..The center hole needs to be opened up on a lathe in order for the plates to reach over the hub to the back of the basket. I will includes some pictures.

In my case one HD steel and one Rivera still allowed the noise to continue. He cut an additional HD steel sent it to me ..again free... and I reassembled the clutch as follows.The 2 modified HD steels first.Then the modified Rivera friction, then then what would normally be the first rivera steel(.120" ) and the rest of the clutch pack alternating friction /steel ...etc..

Started it up and....silence..just motor noise and some normal open primary noise while the lever is pulled in...NOW HERES THE DISCLAIMER!
We don't know what effect this will have in the long run..He's on the left coast and rides daily and reports no issues. He has a concern about the bearing failing prematurely but thats not definate and time will tell. I'd personnally rather replace the bearing if it should fail down the line to ride without that rattle can sound cutting into my otherwise enjoyable days out riding.

So I will post some follow up stuff to keep you all informed..but my riding season ends with temps in the 30's.. I know I'm a pussy to all you tuffguys on here..but its my choice and I'll be back riding in the early spring.
