[@dennywinchel2348]

Your not showing a fair comparison. As Donald D, mentioned, HD is restricted by EPA etc. Upgrades with cam, exhaust, intake & tuner will greatly improve the #'s

[@TravelingTall]

Upgrade with what? More Screaming Eagle, or aftermarket? I think you missed what I was saying. The video is about after market vs Screaming Eagle. Not Screaming Eagle with after market. Screaming Eagle 131 or 128 parts exclusively vs aftermarket. You're not the first to say this, so i figured maybe I wasn't clear on the video about what I was saying. You can absolutely get big numbers by adding aftermarket products to your Screaming Eagle 131, but without the aftermarket products the Screaming Eagle 131 and 128 doesn't give you the performance that you can make from an aftermarket build. And, if you use aftermarket products like tuners or etc then you should have just went aftermarket in the first place, because now most likely you've voided your powertrain warranty. Yes, SE has certain guidelines that they have to adhere to, that is true. Yes, Im certain they can get more power out of the 131 if the had free reign to create without limits. Take a look at the King of the Baggers Vance and Hines Bike it was a 131 and it was around 170 HP 160TQ. Again you can get big numbers from the 131 SE but with the help of aftermarket, not SE warranty compliance parts alone. That's what the whole video was about Screaming Eagle 131 Kit vs Aftermarket 124. Thanks for the comment.

[@dennywinchel2348]

Anyway, Really enjoy your videos!

[@chrissmith7669]

Because I’m wanting to do a fullyTÜV Compliant upgrade everything has to either be OEM or fully tested which is rare if the company isn’t based in Europe. This is exactly the kind of information that interests me.

[@ChrisMonopoli]

@@TravelingTall idk maybe you're still not clear enough but yes aftermarket will give you higher numbers, but the reason is because the Harley Screaming Eagle parts still have to meet EPA regulations where aftermarket doesn't have to. It's like the Dodge Cummings engine, back in the days of the 5.9 liter it made good power and torque but then the EPA regulations got stricter, so they changed the engine to a 6.7 liter but the numbers where almost the same and the reason they had to go bigger displacement because the emissions was choking it down so to keep the same power the motor had to get bigger. If you take that 6.7 liter and put "off road" aftermarket parts get rid of the DPF filter and use a tuner that says for off road use only then the numbers are substantially higher. It's kinda the same concept with Harley's 131, because the emissions choke it down the displacement has to be bigger but if you use stuff not regulated by EPA you get a lot more power but that stuff will say for off road use only on it.

[@ChrisMonopoli]

@@dennywinchel2348 the reason the racers are getting those numbers is also because they don't have to meet emissions when they are able to use off road products, so they are not limited. Depending on the state you live in you may be able to get away with more than someone in a place like California where the use the sniffer to test emissions

[@talkingrock7011]

Reliability and warranty so the 131 numbers are different warranty gives game for me , and how much was the cost for the Zippers upgrades and how many places are there to go in case of problems , in the end it’s about more power and reliability hats off to the MOCO engineers making the 128 & 131 available for a factory engine upgrade these probably will be on production bikes in the future ride safe in eastern Tennessee

[@TravelingTall]

I understand, the warranty that comes with the Screaming Eagle can be comforting and it is great that the MoCo is offering a kit like this. However the former 117 stage 4 kit has earned a reputation of not being very reliable. Search the forums, they will tell you. Its good to be covered by warranty, but its better to be built for reliability. If you can avoid the trouble by installing quality parts, i'd rather spend my time riding than waiting for repairs. Thanks for the comment talking rock, I will be making another video going over the complete parts list and cost.

[@wiremuperry4310]

SE 131 kit and creat engine is a waste of money. And people don't realize you're restricted by Harley-Davidson!!!

[@flyinlow6692]

I installed a S&S 124 power package on my 107. Stock heads, throttle body & 475G cam. Very similar #'s to what you made. No regrets man...

[@cjhunter6105]

Ok Tall, I liked the comparison you did here. I have a '18 FLHX and I haven't been completely sold on the 128/131 kits and now that they just introduced a 119/122. I need to see the numbers on the 119 kit to see where my gains would be over my 107 which has a H-D Stage 1(full SE exhaust/wedge hi-flo air cleaner/ProStreet tuner) and I am averaging 45 miles (highway) a gallon before the fuel light comes on. I have seen a few people ask but I haven't seen your reply about your gas mileage on the 124. I work at a H-D dealership and I know the restrictions that Harley has to work under in regards to EPA but like you stated you went for the best bang for your money and I am thinking the same. Once again, what is your gas mileage with the 124 since this is your everyday rider.

[@TravelingTall]

Hey CJ, 210 out of a tank. I reccomend you go with a 468 cam and make more power than the SE 119.

[@berwynbenderjr3888]

I think Zippers is one of the best performance shops around. They did my 110 SE Roadglide a year ago and totally happy with it. It had a lot of engine problems that the dealer could not figure out. I ain't scared of no 131. Bring it!!!!!!!!!!!!!!!!!!

[@kerrianchambers4409]

I had my 103 built to a 110, I run around all the 107, 114, 117’s. I want to find someone with that 131 SE.

[@alwayslearningthefacts5881]

As an old dirt track go karter, engine builder. Bigger is not always better, especally in head porting. smaller runners produce higher volosity in the port. You have a well built well thought out motor.

[@gwattsjr]

The real issue is that Harley is still using a high flow cat in the head pipe and using their tuner which only tunes within EPA guidelines. Harley techs will tell you if you want real power out of their Stage kits use an aftermarket exhaust and aftermarket tuner. The downside is your warranty will immediately be voided if you change the head pipe or use a tuner other than Scream’n Eagle (thank you EPA). I want to see the numbers for the 131 kit with a D&D Billet Cat exhaust and aftermarket tuner. You also need factor in the type of cam as it too can majorly influence power and torque numbers.

[@tonydanzl]

You got it !!! That headpipe in their kit still has a cat. And their restricted tuner. Also correct on HD cams usually lacking compared to aftermarket.

[@bobhog3969]

Do you know if you switch out the head pipe but use a se tuner it will void the warranty as well?

[@imoto4yz]

I would like to see someone do a dyno run with a complete aftermarket exhaust on the 131”

[@ljohnson9440]

@@bobhog3969 They technically could void the warranty because it's illegal to remove the cat from the bike.

[@moulis05]

What if you live in Australia and buy a Harley brand new from a dealer with a stage 1 kit installed by the dealer that includes a Maximus tuner, V&H Big Radius and a screamin eagle heavy breather? Am I buying a brand new bike with no warranty?

[@scottpeters2974]

It's all in the TUNER & CAM!!! Take the 131 SE kit and put an aftermarket cam and tuner and watch out. Bigger valves, ports, cam profiles and a tuner that allows more timing and fuel and you will have great power increases. Basic Hot rodding is all it is. Harley has to be EPA compliant and the after market is more than likely selling kits that are " for offroad or competition use only" . Eventually the EPA will do the smack down on Zippers and many of the other companies just like they have, to Harley and Vance and Hines already!!

[@donalddavis7160]

That 131 is comparably low on numbers because of the EPA compliant tuner H-D has forced us to use. A more aggressive cam and a power vision tuner will significantly increase both HP and TQ

[@hitekmanvn]

This! No one would use a SE cam and the Pro Street Tuner.

[@Itsme-mx5tl]

For this kind of $ I would want the most HP/TQ

[@hellonwheels1332]

exactly and why the zippers is better.

[@ViperVideo]

So thats why I'm stuck with 154 torque and 123 hp. I've seen 131s have 160ish torque and 150ish hp

[@figuratidesigns]

Thanks for the video... I am going with the 107 128 Stage IV kit. It has been on backorder for a month and a half. I basically have the same bike as you do. I bought 3 year extended warranty my guys at my H-D dealership tells me that if anything ever goes wrong with my bike they would fix it under warranty. Just like you I want to be able to hop on my bike and go to California and not be worried about breaking down. Once I get mine done I will come back with some numbers...

[@cabby316]

Absolutely correct. Your bike, your money. Make it your own.

[@rickyhawkins7407]

Good video and information. I had the 114 stage IV installed in my bike when I bought it new two years ago. What I didn’t realize then was that the stage IV was meant for high RPM use and the extra power doesn’t come in until you are higher in the power band. It’s an 800lb bike and I ride two up a lot. My wife and I don’t ride hard and fast like we did twenty years ago. Warranty will be up in two weeks, not extending it. Will probably do a new tuner thus month, possibly a zippers cam next winter. Ride safe.

[@PanM8]

Ricky Hawkins, sounds like your service dept sold you on the horsepower cam. Change to a torque cam. The revs will be lower for useable power. Screamin Eagle torque cam or Red Shift 468 cam. Your dealership's service dept should have explained that to you.

[@frederickparham9095]

Now all Zipper’s Performance has to do is design a performance upgrade for the 131 because Harley would never allow their bikes to perform anywhere near their full potential. Great video!!!

[@DavidTorres-xl2jl]

A 148 sleeper kit maybe? That would be awesome

[@talkingrock7011]

I have the 124 kit on my 07 Roadglide. LOVE it. 139 hp / 150 torque. Dark Horse crank. 40 mpg. It hauls.

[@zsradcliff]

I work at HD dealership in the service dept. We just dyno'd a 2018 CVO Roadglide with a 131, d&d 2-1, and a power vision. It ran 151ft lbs, and about 145hp. That would more towards the higher end of the spectrum. Unless you run both of HD's Screaming Eagle tuners they will most likely void your warranty if it ever gets plugged into the Digital Tech.

[@roadglide]

Push rod motors are the way to go! Absolute tune-able beasts and why we love them. Nice work Tall. Just a matter of time to set all this in motion for the aftermarket. Life’s short, just buy the bike.

[@chrishodapp1962]

The HD 131 kit includes a EPA legal tuner and tune.... therefore less HP and torque numbers.....I suspect your 124 motor is not EPA legal....( more power to ya)👍. also need to know what compression ratio of each motor and what cam is used.... cubic inches is only one small part of the equation.

Correct! I would like to see what this thing makes with a real tuner, exhaust, and a real cam

[@coppertop1875]

I like both the SE and Zipper performance upgrades. The numbers are always subjective. Upgrades always have a contingency. Do the research, ride a buddies bike, as questions. Find the performance arch that works for your riding style. You may not need all that HP because you don’t goose it to 5500rpms or don’t cruise at 100mph. You might like a torque monster that gets you to your performance band quicker and cruising at 88mph. Reliability is the key. Unless you can afford a daily and play toy that is. Either way, keep it rollin guys.

You can add any stage kit work done after the first 60 day to the extended warranty but it all has to be Harley parts and done by Harley techs at a Harley dealership. Just inquire with the finance people at the dealership for more details.

[@jimbeam4111]

It’s most likely more in the tuner than anything. The 131 is restricted with the screaming eagle tuner. The 124 is with the aftermarket tuner. It would be interesting to see what the 131 would do with an aftermarket tuner. It would also be interesting to see what a stock M8 would do with an aftermarket tune.

[@mopar340dave]

That 131 has really thin spigot walls going into the top of case and the cylinder walls are gonna flex...the 124 is much thicker and will stay sealed when it revs=more power and dependability

[@martinXY]

"About 3 months after I bought (product), (manufacturer) came out with something bigger and better". Story of my life. Also, I I have the ability to send companies into receivership just by deciding I like their products and going all in with them.

[@michaelhurst506]

IMHO, a really important difference is in the torque and power curve delivery points--your 124 kit comes on much earlier and stays high through the "street" zone, whereas the HD kit is a higher RPM kit, more in the "racer-boy" zone. For me, and I would guess a large portion of us, the Zipper 124 kit delivers more where it is used around town (1500-2500 rpm) AND for passing etc on the highway (3000-3500 rpm). You made the better choice. The other big difference, of course, is that the HD kit IS EPA certified and warrantied when bought and installed in time by a dealer (incl'g Calif as I recall if you use their mufflers which relocate the catcons).

Great video Tall once again! The 131ci motor just cam out so just give it a little time and all the aftermarket kits will come out for the 131 and it will be beast. If you put a Thundermax tuner and an aftermarket exhaust this Stage IV motor will put out way more power. Any setup that is not EPA compliant will always produce more power and torque.

[@StrokerStevens]

I have a 2020 Ultra Limited and I had put 5000 miles on my bike when I had the 131” kit put on mine here by Bert’s Barracuda Harley-Davidson here in Pinellas Park, FL. I rode it for a few weeks before taking it to Bert’s Black Widow Harley-Davidson in Port Charlotte, FL for a Dyno. I by the way left it stock-ish by using the Harley-Davidson tunes for the Big Bore Kit, anyway It peaked at 4400 RPM as that is where it hit 110 MPH. At 110 MPH it was putting out 121.5 HP and 140 ft lbs torque. A couple weeks later it started to act up, I limped it home in the middle of the night beach ride, and didn’t want to risk any further damage if it was damaging it. Next day I rode it over to the shop and it was riding fine, I was told it may have been an electrical issue and to keep riding it. I parked it for a week, then on July 1st was casually riding to work (70MPH) and it shut down on me. I got it to the shop next day and the rear cylinder had seized up causing damage to the rear jug & piston. It is still at Bert’s Barracuda Harley-Davidson waiting on Harley to send my parts... BTW, I only had 700 miles on the 131” when it seized up and it was 1/4 qt low on oil... I am hoping to get back on her again soon, the sad part is, that I never got to open it up and see what she could do! The ones that did were the Mechanic that installed the kit, the General Manager, & the Dyno Operator... I will advise this, IF you are thinking of getting the 131” kit, even with the Harley cooling fan behind the back jug and the radiator it still puts off a tremendous amount of Heat, it’s a lot hotter than that of the 114”!!!...

Not to stick up for Harley (. I have zippers heads on my 103 ) but it’s the tuner that sets your 124 above that 131. Since H-D got sued by the EPA and are not allowed to sell the race tuner only street tuner those will be the results. Now if someone were to put a powervision on the 131 And a experienced tuner the 131 would put out much better numbers I’m sure

[@glickmpb]

Great video. Many people really dont understand that the screaming eagle stuff by Harley is hobbled by the EPA. My mechanic laughs when I we discuss 110 kits vs the new M8's because the 110 kits absolutely blow away the M8's in performance.

[@wombat8882]

Thanks for the video. As someone who is considering this stuff right now, I think you're giving good info and good advice. However, as some others have noted, you're comparing a maxed-out 124 build with a crippled 131 build. The numbers you see for the H-D 131 have stock exhaust headers with cat converters and EPA-friendly tunes. If someone did with those kits what Zipper did with your kit, optimize the cam, exhaust and tune, no telling what the numbers could be. But it's really difficult to find anybody who's done that, because the people buying 131 right now tend to want to maintain their warranties. It may take a year or more before we start seeing the full power of the 131 show up in KZbin videos.

Love Harleys and owned one for 11yrs. I came to the point that it didn’t make sense to spend 5 or 6 thousand dollars on mods when I could buy a used 18 year old Yamaha with 135 hp at the wheel that weighs less than 500 lbs for 2700 dollars and keep my Electra Glide for long trips.

[@williamquire2115]

I am still stuck on 10000 miles and having to replace guides and working on the valve train at all on that few of miles I just hope those pressed togather flywheels stay true my stock 06 twin cam sure didn't I sold it and went back to shovel other than having to keep a few bolts tight no problem

[@KingCast65]

Yah that's kinda scary. My Duc DS1000 is no fire breathing enterprise but she moves out quite well especially in the twisties.... but no huge issues and closing in on 30K miles.

[@coronapack]

Zippers is taking off.

[@alexanderflippin3721]

Give me the 124 all day !!💪

[@qf76mnd15]

Depending on who's dyno you're on, it seems like they all gives different HP and torque numbers

[@pinkzillerton8612]

You are correct. Every dyno will read different. Time of day,temp, humidity, and how much the dyno operator fudges the settings will make big changes.

[@richyv100]

after watching your videos i decided to do just the cam (468) and the d&d 2into1. with a tuner (not harley). i had the work done at my local dealership and they had it dyno tuned. it runs a lot better, but not where i thought it would be. only making 103hp and 113ft lbs at 2700. still happy with it though. thanks for sharing.

[@TravelingTall]

Sounds like a good build. What tuner did you use?

[@richyv100]

@@TravelingTall the maximus. after seeing what they were able to get out of your fathers bike, i was hoping for a bit more torque with the 2into1.

[@johnberry8117]

124” is probably getting better gas mileage & you got better numbers than the 131” it’s a good deal. Good video.

[@403punk3]

I have been waiting for this one 👍🏼

[@dennism103]

Man u really luv Harley Davidson, thx for representing the brand

[@billroosa8613]

How much did the zippers kit end up costing compared to the SE 131? Thanks

[@danthousand9662]

Those numbers from screaming eagle are the baseline setup running the se tuner. They won’t dial the bike up due to warranty issues. Put a different tuner on and tweak that setup and guys are hitting 140’s hp/torque

[@harryhowell5644]

Just got to say I just got stage 2 kit installed on my ultra, plenty fast enough for me. HD torque cam the rest is S&S so. Smooth, love it

[@Leroy71893]

They’re using the HD tuner, which is junk. These numbers will jump substantially with an after market tuner. Good numbers on your build.

[@charlieryan1736]

I think you made a smart choice Tall 👍🏻

[@kevinashleylewis]

I love that you still call it a sleeper kit but have a giant 124 billboard on the side of the bike. Lol

[@TravelingTall]

Lol, I know, but thats what the kit is called.

[@brentg231]

I think the results of this comparison would be wildly different if the SE 131 had the same RedShift 472 or maybe the 468 cam in it, along with an upgraded Cam plate and oil pump. The new SE 131 package uses the same SE 515 cam which comes on the stage IV kits... which is why I switched to the RedShift 468 on my 117 Fatboy.

[@chrisbarr5700]

The 131 and 128 kits come with the new set 517 cam.

[@brentg231]

Chris Barr - I stand corrected... Good point. However, there’s still no magic that would allow “Tall’s” 124 to dramatically outperform a 131 beyond the usual suspects of a more aggressive cam, upgraded air intake/exhaust, upgraded injectors or the tune itself. My point is... all else being equal, the 131 should slightly outperform. In his comparison, all else ISN’T equal. If that were the case, I’d brag about my 117 being able to outperform the new 131. But I won’t bc I have several upgrades that dictate that I should be making more hp and tq.

[@davypig571]

Comparison probably should’ve had out the door prices. That would be nice to see.

[@chldof1truekng434]

Good information, thanks for sharing.

[@spencerb8609]

You made the right choice

[@bobhog3969]

I’m not sure when but I definitely want this kit on my lowrider 107. And prob just do one of the redshift cams like you did. Zippers knows what’s up👌. Do you know if zippers has a place they know can do quality work in California? Or do I have to make a trip to Maryland

[@jamesatkins8821]

I turned my 107 into a 128. Got 114 inch flywheels and sent them to dark horse then got 128 S&S jugs and pistons and sent my heads to ward performance. I made 144tq and 150hp

[@rext8473]

Whatever Harley builds MUST meet EPA standards and also carry a warranty!! So the power numbers are definitely gonna be lower than aftermarket. Aftermarket does not have to use catalytic converters and meet EPA standards. Just like Tall stated. It is totally up to you the owner and your budget. Ride safe and enjoy!!

[@kenstar1862]

HD is all about the Torque ,HD since they are not high revving engines the torque power come in at low to mid range rpms, that 131cu motor with some upgrades will give you 140lbs torque at 5k-6k rpms depending on the upgrades

[@trainwreck1518]

Just curious why HD threw in a 517 cam and not a bigger one?! With heads and bigger TB I’d think it would do better against Zippers.

[@markjensen8372]

What kind of mileage do you get with your bike I travel a lot I do a lot of miles I'm really curious what kind of mileage you get with your bike without honor if you have any information about the 131 mileage that kids I would appreciate it

[@TravelingTall]

I haven't been easy on the throttle since the install, but I will be making a 1600 mile trip coming up soon. I can tell you what I'm getting now is about 215 out of my 6 gallon tank. Thats mainly running around town with the occasional blast off :)

[@philipstaite4775]

Amazing how flat the torque curve of your engine is up top.

[@TravelingTall]

Thanks for watching Phillip

[@brettgodfrey9536]

Great, thought-provoking video. It seems from the comments that most people believe the 131 with power vision and aftermarket cam, with new pipe give extreme performance, including substantial boost at lower rpm. Do I have this right?

[@cuzimaluzer777]

Zippers is kings of the M8 game.

[@chriscallaway2841]

Do you have a cost comparison?

[@TravelingTall]

The Zippers kit is cheaper but, there is a few more things that I needed that I would suggest to you. The Screaming Eagle kit suggest a few more things needed as well. I will make another video showing you what installed and the cost soon. Thanks for watching.

[@cgscprspecialist3937]

Great information I have used zippers in the old days

[@timgillenwater1503]

A good dealership will have a lot of dyno data on what parts will and won't produce the best bang for your buck. Some will have their own packages and upgrades to offer. It's not about just grabbing a catalog and bolting things on. Spend a lot of time asking questions and find a dealership that can answer them and you feel comfortable with. If the change does work, then it shouldn't stay on your bike.

[@joesainato8051]

Warranty is always a concern people have and that is understandable. If you take your bike to a reputable shop or HD dealer they will stand behind their work. Catastrophic failure on a big build is very expensive, been there. With that said going to aftermarket has and always will be the key to more power. It’s not just HD, it’s cars trucks atvs snowmobiles etc. The manufactures build things to make the masses happy and able to go down the road. Aftermarket builds things now days to make you happy but add the grin from ear to ear like a kid on Christmas plus the reliability is very good as well. I will take your 124 all day long and twice on Sunday before I would even entertain that 131. SE 131 is for the guys who want the big motor but didn’t do the research to see what they could of had for the same money. But hey it says 131 so it must be a killer bike.

[@stephenchristopherheinrich7531]

This is the information i needed. Thank you my Brother!

[@MEGLADAD]

It's good to compare side by side power and parts..You definitely want the best bang for your buck...124 wins hands down!! I suppose it all comes down to the warranty issue..The 131 has to be tuned down for the HD warranty..Im sure you could wake it up a bit..I'd like to see some aftermarket tunes on the 131..Try and do an episode on that..would be very interesting to see what people are getting out of their 131's when they play around with different parts, exhaust, etc..

[@codybrookehanson2346]

DANG! The choice is obvious

[@thejerseyj9422]

While I support The Motor Company and want them to succeed in the face of some serious competition from Indian. The fact is it comes down to bang for the buck and, at what time can you do the upgrades. 60 days is not alot of time to come up with the extra dough for a warranty covered modification. I think Harley ought to give us more time. After all, it's their bike and their kit, what's the problem ? Anyway, you covered the issue fairly and honestly so, well done. PS, I'm only a couple of hours from Zippers and cant be warranted anyway, Hmmm.

[@KevinButler816]

It’s apples to oranges because the aftermarket doesn’t have to meet the EPA guidelines. Now take that same 131 and use non EPA compliant tuner and cams and you’ll see a huge difference. Fuel Moto just did a 131 build using all Harley SE parts and the numbers were 127 HP 139 TQ rear wheel. They are now in the process of trying new cams and a aftermarket tuner. That being said I agree to go with aftermarket if you’re out of warranty or warranty doesn’t concern you.

[@TravelingTall]

I haven't seen the video. Post a link.

[@TravelingTall]

122 and 137 that's better then HD stated but it should be stouter coming from a 131. It's cool that the moco is offering a 131.
