Cam Shootout Series | Part 3 Big Bore 124 & 128 Cam Comparison with M8 Stock Heads 

Great information! You all are the best Harley-Davidson dealership providing this type of information and service. Kudos to you three and your staff/team for putting out solid content.

You guys are awesome. Can't wait till my SG is on the table.

Another great and informative video!! Keep em coming!!!!🤘🏻

For all you guys that can’t afford Moonshines engine upgrades try this...... Rode my Electra glide standard 107 up to them from Florida in May. They put S&S 465G cam chest kit, fulsac headers, power vision Tuner, and I just put TAB BAM stick mufflers on for sound. Now running 101 HP and 120 Tork! Now I have the power and sound! Thanks Moonshine!

I think this is the best video of the 124/128 technical data at this time. The numbers do not lie. The fact that you guys have put the time into this speaks volume of the professionals you are. We will be in touch soon for our 21 Road Glide Limited.

And thanks for the video!!! Found you guys and now subscribed!!

I could listen to you guys all day.

Great video. Y'all answered some of questions.

(It's me again) Great video gents! I'm looking forward to the shootout with performance heads and intake!

great video guys, thanks for sharing. Cheers

WOW!!! I'm glad I watched this!! I'm currently shopping for my second touring bike and wasn't really feeling the 131's torq specs (which we can't get in Cali). I'll wait and am excited for the next video comparison with the heads to make my final decision.

Good video and alot of great information. Thanks guys

Great information guys and awesome comic relief. 😂😂😂👍

Beautiful show

You nailed it Mike about torque vs horsepower on a V Twin

Awesome content

I appreciate the information I think you might have just convinced me on the 128👍

Can’t wait for the next video. Best Harley content.

I’m going to call and ask for a 131 now. Looking forward to seeing what my 550 will do on the Dyno at the end of the month.

Aaron mentioned Dakota Digital instruments and I looked them up. I immediately bought a MLX-3000 Series for my ‘18 FXFB.

Dudes. Like I was thinking about my 95" s@s twin cam . Runs great loaded ! 14THOU klm . Last year

Absolutely correct about the fuel mileage, riding to work and home I get 30-35mpg, on a road trip running 70-80mph I get stock mileage.

Awesome videos, been watching all week. When is the ported head big cam shootout coming?

Very nice

Love seeing your guys videos great information definitely learn A lot from your video keep them coming!!! 👍🏻 Question is screaming eagle any good?? I have S.E. On my 16FLSS. K&N filter, S.E.Street Cannons, S.E & a auto smart tuner. I went to put S.E. 585 cams on but H-D dealer couldn’t put them on apparently it’s illegal in California 🤦🏻‍♂️ I would either have to go to Nevada or Arizona to have them installed.

As I'm in Europe, I can't take my bike to Moonshine. So I got a Fuel Moto 128" (same as S&S but with a FM badge) 10.75:1 kit with their Wood WM8-22X-E cam, DynoJet PV w/ Target Tune, 5.5g/s injectors, Feuling RS plate and pump, Wood lifters, SE 64mm throttle body w/ Ward ported manifold, Feuling valve springs, SE Heavy Breather Extreme A/C, Jackpot 2-1-2 headers and Hi Roller mufflers, Dark Horse comp, and Barnett Scorpion Lock-up clutch. Motor still needs to be built though, so no numbers yet, but I should expect 130+ HP, and 140+ TQ.

love your content and education so that we can make an informed decision on upgrading our Harleys. Have you checked out the Fueling 3 valve heads?

you guys are rockin it , one question why dont you use any tman cams like the 4059 for a 128 build

Great video!!!! One question, with that kind of power those big bore are making. Do I need to upgrade the oil cooler? More power more heat.

How does that 55mm intake set up work on a stage 2 114? Great video as usual, guys. Thanks!

Nice comparison gents.. i hope some day you give Jim's VTwin Performance cams a try.

Need that for 103

Kudos on all the work you guys do with the trial and error. I'm not made of money so the Harley 131 sounds like a better solution. My 17 SGS is in the shop now because of the oil sumping issue at 30,000 miles. A badly engineered oil pump from the factory jacked up the entire engine. If I hadn't got the Extended Service Plan, I would be looking at thousands of dollars in repair costs. I am going with the Harley 128 Stage kit, get it covered under the ESP and if I have any more issues I am going to sell and go buy a Goldwing, Indian or BMW.

Does the 492 cam require new valve springs ? Thank you and I love your videos

Company I work for is talking about moving me to Franklin TN and my first thought is how far is that from Moonshine Harley.... bout10 mins hell ya 👍👍😁

Another “da shit” vid , great job 👍🏾

If I was in the states I’d get you guys to build my bike for sure but I’m in Australia. Building a S&S 128 into my 2020 RGS, all the goodies but stock heads for now. I’ve gone with a CR480 cam and deciding between D&D Billet Cat and Bassani RR3 mid (for looks). Am I on the right track in your opinion?

Was laughing at through the first half of the video seeing Mike wearing a shirt with Jamie on it. Midway through it's covered with blue tape

This is an amazingly informative video! Thank you for the time and effort you gents put into shooting and testing. Ive got 11:1 120ci Pistons and Feuling 508 cam. (S&S oil pump springs rods etc) and 55m SE manifold going into my build. Stock heads Supertrapp/Scremin Eagle exhaust. Is the 508 cam a good choice for this setup? Sadly there isnt much info about the cam. What experience do you have with the 508?

Would like to see s&s 550 cam with 131 configurations...for max tq and hp...great videos

Is it more expensive to upgrade to a 131 harley or 128 moonshine? And how long is build time for 128

Horse power is how fast the torque works its magic

I have a breakout 114, can I install a 128ci bore kit with the stock can and springs? I know that is not the best configuration but I want to know if it’s something damaged if I do that…. I’ll install 590 cam and oil pump in the future.

Mike looks like he worked 100hours the last week

You referenced the moonshine exhaust package a few times. Will you elaborate what parts you use?

So I have a 2019 Road King Special 114 with SE stage I. I want to upgrade to stage II, I’ve been looking at the SE515 cam. And keeping the rest stock parts. I only say SE parts as I want to maintain my extended warranty (Active duty military) and I move around a lot (having that piece of mind helps) My question is besides the valve springs and the cam what else should I upgrade ( plan on doing a self install and having the dealership retune the bike)

you did not mention which big bore kit's your using eg. Harley Screaming Eagle, fuel moto, S&S -or the compression ratio ? i'm in western Canada and there is no way i could bring my bike there-my bike is a 2019 FXBB street bob 107 I want to do a 124ci with the 475 cam looking for 145tq ,thanks love your channel

Awesome videos guys thank you for all the work you put in. Have you tested the Khrome Werks full exhaust? I know the MX and D&D are great, I just like the look of the “eclipse chrome” that Khrome Werks does. Are the 2-2 or 2-1 Khrome Werks full exhaust systems good for the 114 comparatively speaking? Thanks again for the awesome work!

What's your thoughts on a 64mm throttle body with a 128 and a t man 3262/ 590 cam stage two heads from zippers and d&d xcat 2into 2 head pipe. ???

I'm not surprised about cam performance after the came shootout. Displacement usually multiplys power. The difference really would have changed if the heads flowed better. sorry if that's redundant

So a tech question for Moonshine. Does the sleeper concept(s&s475 w/ moonshine exhaust) apply to the softails as well? Or, is it because of the exhaust and the set up of softails that would make this type of power not apply to the softails(I own a lowrider S, RS472 cam, bassani prostreets, 130tq and 113hp). Just curious.

Great information and much appreciated. I watched the entire vid but maybe I missed it, did you have to do injector upgrades for any of these builds?

Can you make a comparison between the fullsac headpipes and the d&d xcat.

Did you ever do part 4 for the builds with heads done?

Good video. Have you guys done much with TBR exhausts? Specifically the comp s? I have it on my bike and love it overall.

A few years down the road I’m going to get a Roadglide from you guys and have you guys do the 128.

Great Videos! I’ve learned so much from you guys! I have a question. What cam would you recommend for Max torque/HP and touring reliability using using 124 Rev Perf Cylinders, SE Heads, and D&D Billet Cat? I currently have a Wood wm8-408 and it seems to be beating up my valve train (Valve noise, noisy lifter, TB reversion, etc). About to go In and sure things up. Any feedback on Cam choice would be greatly appreciated!

Do you guys think the 475 S&S cam is better than a WM8 22XE. Bob woods cam in a 114. Or 128 stock headset

Are y’all tuning frame stabilizers? If so which one?

For myself, I'm a little confused, and 'let down,' by HD. I just purchased an '04,' Heritage Softail, "88." It's all stock, and as far as I can tell, 'all original.' Right down to the leaky O ring on the clutch cable, I will be replacing this week... I've ridden the bike less than 300 miles in this past month, and you don't even want to know the $$$ I've already put into it, for parts, tools, oils, etc., and ofcourse, the monthly payment to the bank! There seems to be few people happy with anything "stock," on an HD and it's usually for 2 reasons... First, most experienced HD riders always want more power, torque, and sound. "Bigger is bader," seems to be the moto. "You just gotta step it up to the next biggest, baddest... Thing!" And I get that to a point. Like shoes, you outgrow your first ones and you are ready for the next bigger size. Secondly, and more importantly... It would appear that a stock HD engine is, in a nutshell, "CRAP!" I have listened to many people, who tell you of everything that can and does go wrong with stock engines and parts, from twisting crankshafts (crankshaft runout), terrible plastic shoes on chain tensioners, the poor design of the "tapered connecting rods," cam and tappet "hardness glaze," coming off, Cam plate and oil pump destruction, Cam bearing wearout, on and on, etc., etc... But because HD is such an 'Icon,' (Although it's 'less American made' nowadays), in the US and the world for that matter, there has become this, "Aftermarket culture," where everyone feeds on the fact that HDs in stock configuration are cheap, flimsy, poorly designed money pits. And the aftermarket feeds on this like hungry piranha, on all the meat, in a man's wallet! In the end, what I get from all of this, is that if you spend the $24K+, for a new HD, no matter the size engine, or you get a used bike... Just go ahead and plan on spending double the $$$ to have the engine and tranny rebuilt with better made, aftermarket parts. Or replaced, all together, for something built better, with better parts, better design, and built the way America used to build a lot of things... Better power, better torque, better sound, will only be achieved, by how much money one is willing to feed to the aftermarket piranha! When I say "Piranha," that's not a term I mean entirely negatively. Take these fellows at Moonshine HD. They are all about the numbers... They eat, sleep, shit, puke, numbers all day long! It's like a secret society, speaking in riddles and codes! LOL But they have created a living from doing what they do... They pay their bills, feed their families, and have established a reputation, for the work they do. And for their efforts, they have become just a few of the school of piranha, that take a crappy, stock bike, and turn it into what dreams the owner may have for it. "But dreams ain't free and they ain't cheap!" And along with Moonshine HD, there are literally hundreds, if not thousands of aftermarket products, some great, some not so much, but ALL part of the piranha schools out there, just waiting for someone to step into the tepid waters of the HD world!

A motor converts electrical energy into mechanical energy while an engine converts various other forms of energy to mechanical energy. An engine is a mechanical device that uses a fuel source to create an output.

I have a stage 3 Screamin Eagle kit on my 2018 Fat Bob, would a Thrashin AR exhaust match well with the Screamin Eagle Round Extreme-Flow Air Cleaner? Will I need the Smart Tune Pro since I live in the mountains?

What tuner are u guys using on all of these builds?

@moonshine harley, dumb question, does your 124/128 upgrades come with any warranty?? I just bought my 2020 RGS and new bike, don’t mind spending the money on a setup, but can’t do a new setup and possible issues later. $$$ decent but not rich. Lol. Thanks -Brion

The 521 your talking about is that the feuling 521?

Do you guys sell kits for your customers to put together themselves or have local shops put together for them? I’m looking for a 128” set up for my 2018 street glide special. Looking for great power and torque with a good sounding exhaust. Right now it only has a stage 1, with rineharts

When will the video with CNC heads and larger cams be out? What power level do you recommend putting in the fueling head studs?

Do you have any experience with the Chris Rivas 474 and/or 544 cam? Leaning towards an S&S 124 build with head work and the 544.

Why don't you guys use the s&s 55o cam? I have a low rider and if i got to spend all this money i want a cam that sounds hot! What do you recommend?

I’ve been thinking about ditching my SnS 550 cam for something with more torque. It comes on about 2800-3000, been thinking about the 521 or 538. My bike is a 124 with Fuel Motos ported heads, SE 64, Ward CNC manifold, and D&D standard bore billet cat S&S really needs to come out with something between the 550 and the 475.

How does the S&S superstreet exhaust do on built motors?

👍

What sort of money are we talking to go from stock 114 fat bob to 128?

What’s the 492 cam spec. It’s bad ass. Thank you

Why does the horsepower and torque cross at 4700 rpm instead of 5250?

So you guys mentioned the larger cams can have a significant drop in TQ down low on the smaller bikes with shorter exhausts. I ride a 19 low rider with a bassani 2 into 1, and am hoping to upgrade my 107 to a 124. What cam do you suggest i use? Something like the 475? Im not planning on changing heads or throttle body.

What TB would i match with my Softail 475 /128? Stock55; se55; se64? The uk tuners just don't have your experience.. Cheers.

Great video guys! #stocksucks

Any results on cam shoot out with higher lift like 588 605 cam?

HAVE YOU USED THE WM8-408 ,WM8-4860 CAMS AND WHAT WERE YOUR ###'S ???

You guys have the best information for performance to your Harley. In time I plan on buying a Road Glide Special with the114. What do you recommend to get at least 125 hp and about 135 torque. All across. Riding would be in city and with road trips.

@Moonshine Harley I have a 2018 Heritage 114. Factory warranty runs out on Sept. 24. But, I have a Discount ESP warranty that begins when the factory warranty runs out. The Discount ESP warranty is not voided if you use aftermarket parts or tuners, but it doesn't cover those parts. It covers the bike itself and any H-D/Screaming Eagle parts. This means I can use a PowerVision, aftermarket air cleaner, pipes, and those specific items aren't covered but the engine is covered as long as I use the H-D 131 kit. I am referring to the new (Sept 2020) Softail 131 kit. Laying all that out in some detail to avoid misunderstandings. Because of how my warranty works, I would rather use the H-D 131 than an S&S 128. I am in North Carolina about 8 hours from Nashville TN. My question is, is there a body of knowledge of what I can do to maximize the 131 while maintaining reliability? I have a K&H/FuelMoto AC already installed that advertises 80% greater airflow than stock, and says it's "dyno proven" to support 150HP applications. It is based on a K&H Sidedraft but modified for FM to keep the OE outer plate. So I think I'm good there, though tell me if I'm wrong. I am planning to get D&D Fat Cat pipes. I have a PowerVision that I'd plan to use for tuning. I haven't seen any info about cam options for this kit (other than the one it comes with), so that's my main question, along with anything I did NOT ask about but should have. Thanks for any suggestions!

How do you like the s&s 2-1 pipe for a 124” d Softtail?

Now I'm wondering how well the 55aluminium Manifold works with the Wood 22X cam. The 22X cam was the stock lift one that after looking the graphs gave the most gains at every RPM below 4700RPM. I was gonna go with the 475c, but like Mike said, HP doesnt even come into play at 5250RPM, so the 22X was the queen of the stock lift cams. But I have no idea how it'd react to that 55mm Aluminium manifold. I was lookin to get it in the future just to replace the plastic stock one.

@thiscrazyride when will you guys do a shootout of the big boys? (new S&S 540, S&S 590, RS548, RS552, Reaper 590)

Fuel Moto

Horsepower is a function of your torque and engine RPM. Hence why cams that make their torque down low have less Hp than a cam that makes its torque higher in the RPM range.

ARE THE CRATE 131 CYLINDER WALLS BETTER THAN ,DROP IN KITS , OR THE SAME ?????? THANKS !!

Do you have to beef up the trans? How are they holding up to these?

You touched on reliability of the 124/128 builds (s&s 124 550 cam), what are you seeing for reliability?

is the 472 a torque or power cam for the 114 m8?

Dallas Harley Davidson just put a 131 on a heritage softail a few days ago

I'm sure the clutch will need to be upgraded also with the higher TQ

S&S 550 vs 475 with 4.625 stroke 4.280 Bore stock heads 55mm or 62mm

What about burns stainless side dump

So obviously I have missed something at some point ..... why are you getting so much more power out of the m8 in baggers vs the soft tails or did I miss understand the info...?

I wonder how the star racing 30 30 cm would do with the 128 setup with stock heads

Are you guys not using Fullsac headpipes anymore? Just curious!!

whats your thought on TMAN cam and heads?

How do y’all feel about HPI exhaust?
