Screaming Eagle Performance Clutch Kit (38002-04)

[Phaedrus]

I had hoped to be posting my installation of this kit in the "How To" forum, but in spite of what Harley says in their catalog, the Screaming Eagle Performance Clutch Kit, part # 38002-04, will not fit in the XR1200.

Harley describes this as:

Performance clutch kit converts the 8-plate clutch to a 9-plate design. The surface area is increased by 13%, and the spring rate is increased by 10% for a combination that can handle over 115 lb.-ft. of torque at the crank, a 23% increase over the stock-rated capacity. Kit includes Kevlar®-based friction discs and performance clutch spring.
And states:

Fits '91-later XL and XR models, and '94-'97 Evolution® 1340-equipped models.
However, the stack height of the extra plate kit is too tall for the XR. The kit relies on removal of a mid-stack spring plate from the XL clutch to accomodate the extra plate. The XR1200 does not have this spring plate in its stack and therefore the stack height of the Screaming Eagle clutch kit is too tall for the XR1200.

Sorry I don't have better news...

[Fat Billy]

Hey Phaedrus, Can you leave out the extra plate and it work ok? That would help with better plates and stronger and stronger spring would'nt it? My clutch is fine with 85 hp but you guys pushing over 100 may need some help. Later,

Oh Ponderous One,

The short answer is - that should work.

I mic'd the plates and it looks like the steels and the fiber plates are the same thickness as the XR1200's stock plates. The steels are probably the same part number. The Screaming Eagle kit has Kevlar based friction plates and a stiffer spring. It ought to dissipate heat better and clamp a little stronger if you just replaced the stock XR1200 plates with the same number of plates from the 38002-04 kit.

Or - I've got a Barnett MT-77 clutch spring in mine now with the stock plates and it holds just fine. A warning though, the MT-77 is a heavy spring and will give your clutch hand a workout. I wouldn't suggest it for people with small hands, or those who prefer a light clutch feel.

I'd hoped the SE clutch would give the same clamping force with a lighter spring - but no go.

Hi Phaedrus, Please let us know how the pull with the Barnett Mt-77 and Muller Power clutch compares to the standard XR setup.
Thanks in advance

Just curious if you were able to use the SE clutch kit. When my clutch blew-up I ordered the kit and since it was under warranty, I let the delearship do it. They called me later and said that it wouldn't work. They however used the spring from the kit on my stock clutch. Just wondering what came of this. Thanks.

Sorry to brink back an old thread..

Has anyone documented a clutch servicing yet with pictures? do we need any special tools?
I looked through an old sportester manual from 10 years ago and theres a crazy spring compressor tool in there but i would like to know if we can do it ourselves?

Cheers

Elie53, welcome to the forum.

We have several members who have been into their clutch.....I'm sure they will be able to help you...where are you?

[JoeP]

Elie53, ....where are you?

LOL - who does he get that from?

So, did anyone ever link a good thread about working on the clutch?

Phaedrus, what is your "long term" report on the Barnett MT-77 clutch spring? Does it offer more grab or just a stronger spring? How does it hold up to your engine's extra power?

[streettracker]

JoeP you're slipping, you didn't hammer him to do an intro!!! Elie53 do an intro, let everyone know who ya are and where your from, you'll get better responses here that way.

[JoeP]

My Apologies!

Yes Elie53, it's just good courtesy on our forum. I think I'm the unofficial Intro Cop.

Unfortunately you still need one of those spring compressors. There was a great photo documentation on the xlforum

FWIW One of the best improvement I have made is getting rid of the stock clutch spring. I looked into this quite a while ago (after have lots of clutch plate wear/slipping problems) so the figures are off the top of my head and may be a bit out......but if I recall correctly:

1. The stock XR1200 springs are 20% lighter than the pre 2005 sportsters.
2. The Barnet MT-77 is 25% stronger than the pre 2005 sportster.......so the MT77 is 56% stronger than the stock XR spring and may be overkill on a std XR.
3. I went with the screaming eagle spring which is 10% stronger than the 2005 sportster spring. That makes it 37.5% stronger than the stock XR spring, so you will feel a difference in your left hand as well as the instant grab. You wont feel that faint torque slip when you wind on in 4th and 5th gear......and the bike lifts changing hard into second....sometimes even third.

I think the stock plates are fine.....it is just the spring that sucks

Sorry cant find the exact one I used but it is either 37951-98 or 37949-98A

THE V&H Race Series notes the 98A as the only approved clutch spring replacement.

Found the packet. It was the 37949-98A.

[silja]

Hello,

I've been thinking of upgrading my clutch by something stronger than the stock, since the work done on the engine, and all my hard riding, that made me decide I'll replace the clutch by performance components when the stock is burned.

And now here we are, its slipping more and more at high revs, the stock clutch needs replacement.

I see you guys talked about the screamming eagle performance clutch, whith it's extra place. I think it's interesting, but I hear different things: does it work on the XR,yes or no ? You guys mentionned ref 37949-98A, XL, all I found was SCREAMIN' EAGLE PERFORMANCE CLUTCH KIT ref# 38002-04, sold 169$ at Ronnie, mentioned to work on big twins, an XL -1991-2012. Any info on the correct ref# ??

I had my eye set initially on the Barnett one, ref 306-30-20015.
It's a performance kit made for Buells and apparently also XR. I don't know if it offers an extra plate, and extra surface as well, but I'll be trusting this one much more than the Screamming Eagle, that I never heard about before today;

Anyone ever tried the Barnett kits ?

it can be viewed here

All I'm looking for is the best performance. what do you think is the best? anyone know maybe some other brand ?


thx

[Fahqracing]

I just did mine yesterday with the Barnett Kit and stock spring.
The job was a little tougher that I though it would.
I had to make a special screw driver to use the Barnett Spring compression tool.
I destroyed the spring seat too.
I could have used a third hand during the reassembly process.
The results are awesome so far. Wheelies are back in play and 5th gear roll ons are finally working again.
I was on a weak clutch since Septemeber last year.

[silja]

oh yeah the spring comrpession tool. Which brand do you guys recommend ? I saw there is a lot of 'em that exist. You used the Barnett and it didn't work easily ? How come ?!

And you didn' t replace the spring ? I thought that I read the Barnett kit included a new (heavier spring). No ? maybe purchasing a separate spring would be a good idea (which one ?)

And is the barnett kit an extra plate (hence extra surface) solution, or is it just called "performance" because of the material used ?
thx

[admin]

Is Fahqracing the only person to do the Barnett clutch replacement so far? My Honda has a Barnett kit in it and it works great and the install was pretty easy.....but that's a Honda :)

I am looking at a clutch replacement also.

[harry28]

No my mate has the Barnett clutch plates along with the Screaming Eagle Clutch spring,This combo certainly doesn't slip but is quite heavy compared with std, My bike has std plates with the S E clutch spring,Which stopped the slipping in 3rd to 4th and 5th, This is only marginally heavier on the pull at the lever, Whilst giving a more definite feel. My mates bike definitely could do with one of those muller devices but he doesn't like them so he gets a strong hand. His last dyno was 95 horses so he needs the heavier option to alllow for future power upgrades he has planned.

[silja]

you guys use SE clutch spring ?

I thought spring was included in the barnett # 306-30-20015. kit , no ?

[Fahqracing]

The kit only has the plates.
I bought the diaghram spring tool from JP Cycles but is a Barnett part.
This was my first time doing a Harley clutch and I made some rookie manuvers.
Prying the retainer off I also broke the retainer seat which meant I had to take the comression tool off.
There arent enough threads on the tool to get a good bite to thread it back on and I dont have a vise.
I used two C Clamps to get the spring to compress enough to start the threads but that is where I could have used a third hand.
Another useful tip is have the bike on a stand so it is level.
Mine was on the kickstand so the plates wanted to keep sliding off before I could get the spring assembly on.
Overall I am very impressed with the feel and hook up.

[harry28]

I really can't see you having any trouble with just the std plates and the S E spring(under $30), But if you're going for more torque & Hp maybe the Barnett plates would be a good investmest along with a Muller clutch ramp replacement.There are several options for aftermarket springs, There's 3 or 4 on this website just have to find them.S E, Barnett & scotty listed another not long ago.

[Jaybird]

What is the part number for the SE spring ?

Thanks >>>> Inthered


S.E. spring is 37949-98a

you used to be able to get just the H-D plates, part # 38001-04, but it looks like they went obsolete:((didn't save you much$$ going that way, unless you scour e-bay).

[Jeff B]

This thread is going to be saved to my bookmarks just in case. The link to the xl web sight had great how to pics too. Though I have had ironhead clutches out even built the tool I have never done a Diaphragm type

[Scotty]

[98acrsilver]

would using the barnet plates with the stock spring be good or kinda pointless bandaid since it still uses the stock spring

[silja]

we have to know what the barnett plates bring, compared to the SE kit, and to stock.
I think a good compromise would be barnett plates, + SE spring (barnett spring looks to be too extreme for the XR)
I think that's what I'm gonna do.

Right now I'm having a hard time finding the right spring compressor tool.
I'm shoopping on ronnie, and they have 3 models of the barnett one, + the jims and the motion pro, but all are specified working on sporters up to 2006...
anyone can propose a tool that surely works on the XR ?

[Jeff B]

JP cycle has 3 different ones. The Xl forum link was a great read. Read it from front to back. It seems that if to stiff of a spring is used on Sporties it will crack the cast pressure plate, it was recommended to use a billet one. Why any body would need a clutch that hooked up like that is beyond me.

You should be fine with the Barnett clutch plates and discs with the SE spring

Hey! You aren't supposed to be able to right-click their stuff! :nono:

[Fahqracing]

Part number 317-30-30001 has both set ups in the box. (Big twins and XR)(Barnett)
Works fine if you don’t have to disassemble the spring.
I will rent mine for $20 plus S&H or sell for $60..
I hope I did a good enough job to never have to use it again....

[Fahqracing]

I broke #16 thank you very much !!!!!

[silja]

installed SE clutch diaphragm yesterday.

the barnett tool worked perfectly.

The whole disassembling:re assembling was pretty easy and fast.

now the clutch doesen't slip at all.

But OMG now the lever is so hard.
I can't even imagine what woudl it be with the barnett spring.
I guess I'll order the Muller soft clutch soon.

And can the stock clutch cable take the extra force needed ?

[Simon]

I've got the diaphragm spring, ready to go in when I reassemble my motor. I would have thought the stock cable will be fine. I used to run a stock cable on my 124" FXDX with a Primo/Rivera pro-clutch without a problem.

[silja]

In my experience, the stock clutch cable is very fragile. Mine broke suddenly around 9 000 km.

I hope it was just bad luck, but I'm gonna order a barnett cable to have a spare ready!

[Simon]

Let us know how you get on.

Thank you

By the way, where in Paris are you? I'm in France several times for work this year though only near Paris once or twice.

[BillH]

So I'm told by the dealer that the SE clutch won't work. I decided to go with a barnett instead of stock. Still waiting, but I'll let you know the outcome.

[silja]

I live in Bastille, 11the district in Paris.

I just put the SE clutch spring (25 dollars), i kept the stock plates that are still ok.
But I'm planning on replacing them with some good ones like the barnett when the time comes.

And also, by curiosity, I would like to try the barnett plates with the stock spring, to see if it still slips.
The performance springs, se or barnett, are not adapted to everyday use in my opinion, it's really a race orientated product.

[silja]

Anyone knows if in the barnette discs kit (306-30-20015 "Buell XB and XR1200 Race clutch kit from Barnett"), there is the "narrow" friction plate ?

I read that reagular discs kits for sportsters (even the SE performance kit) only include normal sized discs, and not the first one, the narrow (called "37897-02 friction plate narrow B" if I' m not mistaken)

I 'm gonna need soon to change my plates, and I don't know what kit to buy.

[MadDogXR]

...I 'm gonna need soon to change my plates, and I don't know what kit to buy.

How many miles (kilometers) do you have on your bike?

[98acrsilver]

barnett should go right in but uses the stock xr softer spring i think

[superdave]

So, is the consensus for stock plates and SE spring? I'm at 22K miles, and in need of a bit of clutch work very soon.
Thanks.

[springer]

Nope, you can use the Screaming Eagle spring. That's what I used with the Barnett plates. If you want to replace the judder spring and race that will have to be bought seperate from H-D. That is true with the Barnett and the S.E. clutch plate kits.

Hi, I'm new to the forum. I'm wanting to upgrade to the "SE" clutch spring P/N 37949-98A with the Barnett plates. I've tried researching this spring, and this is a couple links I have questions about: http://www.surdyke.com/AdvPartInfo.asp?PartNumber=37949-98A and http://www.ebay.com/itm/Harley-Davidson-Clutch-Pressure-Plate-37912-98A-/200749988257?pt=Motorcycles_Parts_Accessories&hash=item2ebda1b9a1&vxp=mtr. The two links show the same part number but are quite different in prices. Are they the same part? Which is correct? I don't have a lot of cash to spend, so I need the best deal possible. If anyone knows exactly what I will need for this project, it will be greatly appreciated. Thanks.

Welcome jacobsmith, you need to do a proper intro in the welcome section.
Here is a link to my clutch swap.http://www.xr1200ownersgroup.com/site/showthread.php?6327-Springer-s-grinding-cutting-and-painting-oh-my/page7&highlight=cutting%2C+grinding%2C

I went with the Screaming Eagle spring and Barnett plates. If I was going to do it over I would have just ordered the S.E. plates. Not knocking the Barnett ones, just would have made getting the parts easier.

i see that your a fellow Alabamain. I am in the Birmingham area myself and your not far from Magoo.

[jacobsmith]

I've had my bike for a little over 2 years. I was getting disappointed in it a couple months ago. It just wasn't running like it used to. After I installed the V&H Widow and fuelpak, it was a totally different bike. I don't really have a set plan, but I'm sure wanting to put a big bore kit, lifters, adjustable push rods, and roller rockers on it next tax season. I'm not really sure what all will be involved in that build, but I have a while to do some research. I'm just wanting to get a few things lined up for a lot of power in the future, and I figured the clutch would be a good start. I read that the Barnett clutch kit with the SE spring would probably be enough, but I'm still not 100% on that.

[jacobsmith]

Oh, My mistake on the part numbers. I was cutting and pasting not paying attention to the numbers.

[superdave]

For what it is worth, I went with the Screamin Chicken spring with the original stock plates and it made a big improvement for little cash.
Motor is stock.....

[jacobsmith]

Hmm... That may be the way to go until time to big bore it. I do have problems gettin the front end up now. That would probably help some. That would also make more use of the tools I'll have to get, and ease the process some.
