Upgrade Your Twin Cam Clutch!! Don't Let Your Power Slip Away!!

One of the most overlooked parts when adding horsepower and torque is making sure your clutch can handle the power. Your twin cam clutch can handle quite a bit of power with just a heavy duty clutch spring, but it can be better. You'll waste every penny you put into upgrading your motorcycle if you can't get that power to the rear wheel due to a slipping clutch. A slipping clutch will cause major power losses and when if finally gives out you'll be sidelined with your bike down for repairs. We'll look at the the most inexpensive options to more the more radical adjustable replacements to help you make sure you get all of your power where it belongs!

What is your favorite clutch setup, which one would you run on your bike?

[@skippynj1979]

My sporty i have an Energy One extra plate clutch with 15 percent heavy spring. My M8.. I'm thinking of going with the Barnett 🦂. American Prime is on my radar.

[@GixxerFoo]

Barnett makes some awesome products, you can't go wrong with an upgrade from them.

[@stefanbogatu2106]

So.... I think I should share a bit. The final setup on my 103 Dyna is a S&S 583 cams, Arlen Ness stage 2 air filter and a VH 2in1 Pro Pipe. Runs excellent! Night and day difference. BUT... With everything done to it I considered that a Barnett Extra plate and Heavy Duty spring is what I need to handle that power. In addition to this I got a Mueller Power Clutch to ease the pull in this extreme traffic. Still, my clutch was heavy on the hand. Not at all comfortable on the hand. Much heavier than stock. I also got an EZ pull system. Now, yes! the feel is exactly how it should be. But now appears another problem. Very hard to find Neutral given that the ramp of the Mueller is smaller and also the EZ pull reduces the total pull distance on the spring. Now my bike is extremely oil pretentious. Too low oil, the clutch drags and I also risk burning it. Too much oil, the bike drags, as you have a proeminent Tesla Turbine effect. Took me about 2 weeks to adjust it perfectly (for an acceptable result). But, of course, I forgot to tighten the primary oil plug at the correct spec. After 5k miles it loosened and lost a bit of oil. Not I have to readjust everything again... So, if possible, don't combine easy clutch systems. It may be easy on the hand, but finding neutral will be "a drag".

Energy One Extry Plate on 120 squared for 50,000 miles. It has served me well and in addition the gent provides stellar customer service.

[@redbrickbandit]

I’ve done it all man. Started with the SE diaphragm spring. That sucked. I live in NY so traffic is an absolute killer. Then I did the rekluse but I did the auto clutch. Held my 112 tq 105 hp well but burnt out from a dyno tune. Also friction welded my throwout bearing, oil slinger and pushrod together from the constant pressure. 10000 miles. Now I have a Barnett scorpion basket, hub and clutch pack. Best one by faaaaaarrr

[@GixxerFoo]

Oh dang yeah you've got some serious duty on the clutch being in the traffic up there. I'd imagine that clutch spring was awful with the increased lever effort in traffic. Sounds like you went back with the goods to make it last though!

[@toddoverby5538]

TC88 converted to 107 120 hp 124 tq. Nothing crazy but I did burn through a Barnett clutch in a couple months. Two dyno tunes and riding style may have had something to do with it. FYI You cannot run the Rekluse in an aftermarket basket. Ask me how I know. Still have it. Rekluse said the tolerances are too tight on aftermarket baskets and the plates hang up causing difficulty if not impossible shifting and forget about neutral. They told me they were developing their own baskets to work with their clutch packs. (This was in 2020) They supposedly work with the stock basket but I never tried it since my basket was swapped already and I wasn't going backwards. Ended up going with Evolution Basket, Alto Carbonite clutch pack, upped spring pressure to 340# and added the Variable pressure VP84 unit from AIM. The guy at ALTO is the best. LittleO

[@bigbb70]

I have a Trask Billet aluminum clutch basket and a drag specialties hub, Barnett kevlar disc set, Barnett heavy spring, and fuel moto aim variable clutch. This is all on my 2012 flhx with the se120r engine. Lever pull is pretty heavy but I have ZERO slippage. I may have done a little more than necessary but I'm one of those, its easier to do it now while its apart instead of waiting till something fails kind of guy. Love your channel

[@hollywoodboggie]

On my 96 twin cam upgrade I included the Screaming Eagle set of clutch plates including the heavy duty spring. The result is very positive. A real smooth clutch with the friction zone pronounced and easy to handle. Not a great deal of additional force needed although the extra effort does add to the positive feel. A solid upgrade thanks!

[@GixxerFoo]

Very welcome that is awesome to hear! A good clutch really changes the dynamic of the bike!

[@advhawk6455]

At 14k miles with a Stage 1 96 ci Twin Cam my clutch is slipping bad when I pull hard from a stop. I've got a 110 ci kit, Screamin Eagle heads, S&S cams, a FuelPak 4, and a compensator eliminator sitting on the shelf. I'm going to do a coil spring conversion (3 medium and 3 heavy springs) with an extra plate kevlar friction kit, all from Barnett. That should get 'er done.

[@BigRooster616]

I have built several 100hp 100 TQ Twinkie engines. Every time I have used Alto Clutch plates and a S.E. Spring with ATF Fluid in the Primary , with very good results. Supper cheap clutch setup that works great .

[@GixxerFoo]

Great tip! I really like hearing about proven setups like that, it makes sense to me!

[@troyroberts]

Thank you! I am the same way, I get HOG too and I am just pretty much ate up with Harley. You can't beat that feel and ride of a Harley-Davidson!

[@tarmak968]

I went with the heavy spring that came with the tire shredder kit. It only slips when I give it the beans and dump the clutch.

[@GixxerFoo]

Nice! That's a massive amount of torque hitting that clutch, it's pretty impressive the stock clutch can handle the shredder kit.

[@Sam590ss]

The stock clutch slips just a little by design. That was the first upgrade I made to mine. Evolution Industries billet basket and American Prime Manufacturing clutch. NO SLIP.

[@GixxerFoo]

Billet baskets with some new plates are a excellent setup, no one really puts a lot of thought into the clutch until there is an issue!

[@Brad__Gray]

The best option hands down is the clutchwiz. Unfortunately the guy retired and stopped making them but its way better than a VPC. You can run the heaviest spring on the market and itll bring the clutch pull down less than stock. The VPC just allows you to run a lighter diaphragm spring without slip, but it doesnt start working until 3.5k+ rpms. And its noisy. Ive got a 124" in my fxdx and get no slip with the clutchwiz. If you can find one, get it. They randomly pop up for sale. VPC still works but it has flaws for sure.

[@sk8salot88]

Solid videos man!!

[@Manis-World]

EnergyOne clutch pack is the best bang for the buck. It retains stock basket and have worked better than Barnett in most bikes I've put them in... They also offer extra plate and heavy spring options as well. One thing to note with the variable/lock-up clutch plates, you do add a lot more shock to the transmission gears which can cause stress fractures and chipped gears ( especially with the 06+ 6speed trans). A little slippage is a safety cushion for your trans. Oh, and another thing I found with the lock-up pressure plates is to watch for clearance with the old-style derby gaskets; had a bike come in with one that the shrapnel from the gasket went through the primary and took out the stator.

[@GixxerFoo]

That's a good point, even though it say bolt on it's always good to check clearances! Thank you for sharing the info!

[@pb68slab18]

Another system Harley gets the bugs worked out of, then foolishly tries a totally new design! The Rivera Pro-Clutch is a good unit, but I dislike flat springs. I like the Barnett Scorpion I used in my 93" S&S/STD stroker. Noisy as hell in an open application though. Uses coil springs so you can mix springs to your needs. Both run close to $500.

I know what your going to say most bikes the factory calls for more oil in primary ! But I been doing this 1 qt for a long time it is plenty of lubrication ! The half turn on clutch nut makes the lever release by only with about half of the pull perfect for racing !

Energy One extra plate clutch kit seems to work for my 130bhp 122 ftlbs monster..... it has a larger friction area AND a stronger spring, and at a fraction of the price of any Screamin' Eagle kit it is the best value for money. I have fitted a hydraulic operating system with parts from a CVO Fatbob but it doesn't make it lighter to use - no hydraulic operation mechanism does ! Fitting an extra strong clutch spring can place more strain on the clutch hub bearing and you should always remember that heavy use and abuse will threaten the integrity of the stock basket and if that lets go then you may trash the entire primary, cases and all !......

[@GixxerFoo]

You've got a nice plan in place with some very reliable upgrades. Good idea on installing that the variable pressure clutch! That's gonna make a world of difference!

[@bobhoffman5581]

@@GixxerFoo I was wanting to install a "softer" Belleville spring, something I believe I saw in a HD catalog, 2006 version--the tech where I'm having it put in told me that the assist device will work better, and I won't lose any clamping force--something I don't want to happen; I thought the different spring would suffice--I'm no "expert," but I DO have some mechanical ability/intelligence. Rundown on what's going to happen at a later date--I'm still not sure, but I'm leaning toward 10.5:1 (0.010 over) pistons, milled so that my compression ratio is a solid 10:1, aftermarket cams, (S&S has a nice grind for maximum bottom end/mid range) new roller lifters, better pushrods, roller rocker arms, better springs (slightly stiffer, with titanium retainers, if available) pocket ported heads, again, to increase bottom end torque--torque tubes in a Vance&Hines Pro Pipe, and the aforementioned 6-speed conversion. My hp/tq goals should be (easily) attainable, don't you think? My riding partner has a '17 Road King, and chided me about my bike being able to "keep up" with him. I'll meet that "challenge," I believe. Now, to just get my driver's license "issues" resolved! See WHY the better than stock clutch is going in? LOL

[@bobhoffman5581]

OOPS! Forgot to mention the intake & carb upgrade--I was considering a Pegasus EFI system, for riding at "elevation," but that would be a rare occurrence. Talked to a former coworker who goes out West to ride, every year--he just takes a run at the inclines out there, and has dealt with the situation. Really can't justify the added expense, after hearing him. I'll get out there once, maybe twice---if at all. lol

[@GixxerFoo]

I think you'll exceed your horsepower goals pretty handily with what you've got planned. I really like those clutches since the provide more clamping force as the rpms rise without increasing your lever pull effort.

[@GixxerFoo]

Are considering a conversion from a carb?

[@toddoverby5538]

Gixxer Great content! As usual. Would love to see you do some work on stuff if you ever get time. The variable pressure units are good but I don't think they give you any advantage right of the bottom. They have to spin to a couple grand first. Is that correct? That's important to a person who likes to dump the clutch occasionally. LittleO

[@GixxerFoo]

Variable pressure units are a great cost effective option to getting an entirely new clutch, lol but like you said they need the centrifugal force to work which doesn't work for dumping the clutch!

Thanks for this video. I’m about to install a 120st with a woods 408-44 cam. I’m thinking new plates and spring should work well.

That cam is going to make that 120ST live up to it's full potential! Really only difference between the 120ST and R is the cam and the ST comes with a throttle body. The R has the SE 259E which is ehhhh, you'd still want a cam swap with the R motor too.

[@GixxerFoo]

Thank you! Not that I am aware of, I've seen a lot of VP clutches run and you wouldn't know it's there unless someone told you. Unless of course you ride the bike and feel the decreased lever effort.

[@justinc.1818]

Long story short , I was riding my streetglide at night & suddenly my voltage ⚡️ drops to 8v so as I was looking at the voltage ⚡️ dropping I kept pushing the bike with open throttle to get to a gas station , had to tow it home. I replaced the charging system to 54amp drag specialties but when I started it up it won't drop back down to idle , it stays reved at 3000 rpm. What went wrong ?

[@GixxerFoo]

That's pretty much a straight swap, my thought is that you would need to read the live data on engine temperature, voltage and when the bike is supposed to idle down. The higher output of the new charging system might be messing with EITMS (engine idle temperature management system), there might need to be some adjustments made to the values in those tables in the ECM.

[@bodeine454]

We have an '05 Dyna Wide Glide with about 25,000 mls on it and this past summer I installed the Harley-Davidson reduced effort clutch kit (stock engine except for V&H Bigshot exhaust). I also used the lighter spring that comes with the kit and changed the primary fluid to Lucas synthetic 20W 50 oil which is supposed to be OK to use in all three holes. I noticed the clutch slipping a little on gear up changes when getting into the throttle hard but I really like the light clutch lever feel so I'll probably leave it like it is for now, I'm going to look into a possible friction additive that I can pour in if there's such a thing. The plan this coming income tax season is to buy the S&S power package which bumps it up to 100 ci complete with cams, cam plate, push rods etc. If we can swing it I'll probably go with the Recluse clutch setup and possibly upgrade the clutch plates at least that's the initial plan, like always, I'll cross that bridge when the time comes near because I always like to do diligent research first and probably talk to a couple shops before I make any moves.

[@GixxerFoo]

Doing some serious research before you start making purchases is the most important thing ever! I see too many people go buy a bunch of parts and get the wrong combo or decide to upgrade a gain later and find out the cam they bought won't support the higher compression. Sounds like you've got a really good plan laid out for you build! The motorcycle oil in the transmission and the primary is supposed to meet the requirements of the engine, transmission and primary. I've been running Amsoil 20W50 in all three on mine and haven't had any issue. Harley-Davidson i believe does the same thing from the factory on the CVO's these days too.

[@bodeine454]

@@GixxerFoo That's interesting that Harley uses the same oil in all three holes on the CVO's, didn't know that. Yeah from what I've read in recent months most people like Amsoil the best but it's expensive. The reason that I use Lucas is for one, that's what our main Harley mechanic here in Owensboro told me to use and two, we can get it locally here at Rural King. It's still not exactly cheap but for Lucas synthetic it's about the cheapest I've seen anywhere. I also started using HiFlo oil filters this past summer, that's one that Kevin Baxter of Pro Twin Performance recommends. According to their research it's one of the best performing oil filters out there. Check him out on KZbin, he knows his stuff. As far as Lucas synthetic 20W 50 oil in the transmission goes I'm not sure that I'm going to continue running it or at least as is. The transmissions pre 2006 are kinda loud and clanky and sometimes are hard to find neutral, I was hoping that switching to Lucas would help that but it hasn't. There's an oil stabilizer that can be mixed with it and I think it thickens the oil which might help quiet the trans some but I'm going to research that more also, I've heard of thicker oils that might be better in this one (I'm used to the '06 Dyna Wide Glide I had back in '08 with the 6 spd, much smoother and less clanky). I'll most likely go with a mild cam as long as it's compatible with the compression because I don't usually ride in the upper rpm range except for an occasional spirited run from time to time for a short distance, it's mainly windy country roads around here. But the slight clutch slippage changing gears when I'm getting on the throttle hard is kind of a bummer, I'm not sure if that's just normal for a heavier bike with 25,000 miles on it or if whomever owned it before me hotrodded the heck out of it and wore the clutch plates prematurely or if it's just something that happens sometimes because it's such a light spring, it's just another head scratcher, lol. At the least I'll probably upgrade the clutch plates, maybe go with the extra plate kit, but like I said earlier I'll get advice from others with experience first." It ain't nothin but a thang" as they say around here, just things that we all come across when we like to tinker....👍

There's nothing wrong with Lucas, l've used quite a bit of their products too. Amsoil is expensive and difficult to get unless you order, l usually have to order Lucas too. Anything that's not exactly mainstream is hard to find in stores.

No just a tune isn't going to cause the clutch to slip, if you bolted on a turbo and tuned it I could see the clutch slipping a little lol.
