M8 Engine Must Have Upgrades / Harley-Davidson / Engine Building

[@PotatoeJoe69]

I have something important for M8's that recently came onto my radar; something I would have never even thought about and perhaps not even believed, it's significant, it's about pumping and a dirt cheap fix for it, but comes with a short story: I have a 2020 FXST, 107ci. I assumed that I was safe from sumping because of the 2020+ oil pump, and the fact that all the sumping issues appeared too be on touring bikes. Well, I heard about the Sump Plug being too long and blocking off the sump oil pickup hole, and how the plug installed from the factory blocks the pickup. Well, I pulled that plug on my bike, and 10 ounces of oil came out. 10!!! There is supposed to be less than 4 ounces in the sump, and I had 10! My bike was sumping. I replaced the sump plug with a fueling shorty sump plug, and now after 2,000 miles, my sump has less than 1 ounce of oil in it. It's a very, very cheap part, less than $20, and is quality assurance if nothing else. In my case, that tiny screw solved my sumping issues. I wouldn't have believed it if someone else told me, but it worked for my bike.

[@philipjanes]

Good advice. Gotta say though that there's a few must have upgrades on these very expensive machines that Harley should just be doing from the factory. I have a 2022 Road Glide Special with just a stage 1. Not into racing or anything but i guess at some point i should just go stage 2 and have all this done. As long as it is reliable. Like taking my bike on long journeys.

[@geraldgoodiii6993]

I left the stock oil pump in my 2023 road glide when I did the 124. If u do a big bore kit .. do the SE pump and plate. Or the SS etc. only do the SS one with a done up crank. The stock pump won’t keep up on the scavenge side .. u won’t sump but your crankcase pressure is gonna suffer

[@JohnLaggy-f8u]

Through research i did everything you talked about 3 weeks ago on my 2017 SG. including adding a thicker clutch rod to eliminate Trans fluid transfer to the primary. Added a breather line to the trans cover and eliminated oil blow by completely. You are spot on. Great advice .

[@FranBunnyFFXII]

You've never seen an SE Camplate and pump fail? That's pretty awesome. Makes me happier about going with it in my Fat Boy 114 build.

[@MasterTechMiller]

It's the best option out there!

[@geraldgoodiii6993]

I had the AIM SDR lockup originally… but kinda got scared away from horror stories about grenaded gearboxes from lockups on stock gearboxes. Landed up changing for the SE clutch pack and springs along with the muller power pull. It’s the smoothest and lightest clutch. It’s like butter. And a nice friction zone .. SUPER easy for low speed work. Little bit wider of a friction zone which for fast shifts isn’t as ideal .. but still can just do a mini pull on clutch and little power cut with the right hand and shift fast as u want

Hi Tommy great video I have S&S 475 cam installed with S&S lifters etc and was going to fit the S&S pump and plate but on you recommendation I will definitely be going for the SE cam plate and pump and are currently waiting to hear back from my Harley shop on getting this upgrade fitted. So thank you for your input much appreciated. Without doubt my favourite Harley tech to watch. 👍🏻

No. I haven't found any evidence to support them in builds yet. Very high performance strictly race applications may find them beneficial but definitely overkill for even big bore street engines

[@michaellarkin3108]

Great info as always Tommy, told in a succinct manner too.

[@geraldgoodiii6993]

Subbed to your channel M8. I’m here in the states. Anyway …. About to do a 124 on my 107 2023 FLTRX. Gonna do 483 cam. I have a really fkn good builder tuner over at one of the HD dealers by me (could get a killer deal at an Indy shop on this job but I ride so much all year except in snow .. or not on purpose lol .. so I’d rather spend the extra loot and know I got the best man on the job that I know and trust .. anyway .. HD said that I didn’t need to do the ramp. I was a bit taken aback bc I never heard of that not being recommended to change… they had me do the 55mm mani and oil cooler fan and lifter cuffs and lifters etc .. basic support mods but nothing not needed .. so I don’t see them selling unnecessary parts ..When I did stage 2 (did the stupid EPA SE447 and SEPST.. but that tuner was able to make it run amazing despite That SE tuner .. like this dude nailed it. So can’t wait to see what this dude can do with PV. The question I have is did they improve the compensator design in the newer bikes ? Like that oil pump and cam plate in the brand new bikes are great. Even Bryce from Star racing said that latest OEM design is way better than the SS and Fueling options… better scavenge on the OEM design. But yea I’d love your thoughts on that compensator. Thank u

[@MasterTechMiller]

Thanks for watching & subbing mate. Much appreciated!! The stock compensator ramp is trash! If you are doing a big bore kit, there is NO WAY I wouldn't recommend doing it. Let me know how you go with your PV Tune when you get it done.

[@michaelthompson7001]

you should have mentioned replacing the plastic intake manifold with an S+S or Ward aluminum one, the plastic one needs to go

[@MasterTechMiller]

In performance applications it needs to be swapped out but otherwise the OEM one is just fine. I don't deem it to be a must have upgrade for all which is why I left it out Most of the builds I do end up with a bigger 64mm Throttlebody & as a result the manifold is swapped

[@odetterollinson-davies4543]

I’ve had the 131 SE kit so guess some of these are upgraded in the kit?, still got to do compensator to do though for sure done the SE cam plate too

[@MasterTechMiller]

Absolutely! The compensator is a must with the 131.

[@ricko9879]

Jesus that shits me. Had a 131 built by a local dealer and didn't tell me how pathetic the SE cam is, so had to cough up for a CR512 install and it's a completely different beast. But of course, no one has ever said anything about the compensator.. @MasterTechMiller

Thanks loved the upload. Reassuring 👌 that my build has, like I excepted, all the correct goodies. Would love some advice on M8 air intake upgrades. I have RG ST, 117 with a Zippers 468 cam, Freedom 2 into 1 exhaust, upgrade Screamin Eagle air intake/filter. Loud and lumpy 😂 I’ll be coming up to my first major service 8000ks, and thinking of doing the air intake manifold and possibly the throttle body as well. ?Screamin Eagle 64mm setup or something equivalent. Firstly is this over kill on a stock head bike? What would you recommend? I’m looking at picking up some more HP Thanks in advance

[@seanoconnor8895]

Would u recommend upgrading the flywheel?… taking the balancer out… wielding it… or changing all together when going 140hp +?

[@MasterTechMiller]

In most cases it fine to use the OEM Flywheel. If you intend to give the bike a proper hard time then for sure, I highly recommend either the welded & plugged OEM flywheel or something from the aftermarket (Darkhorse or S&S)

great video.. thanks for sharing your thoughts on those upgrades. I am in the process of putting together a parts list for a stage 2 cam upgrade for my 22 Road Glide ST 117. I'm looking at the Star 30/30 cam and was originally going with an S&S oil pump and cam plate. I guess I'm now changing it to the SE version. My parts list include Feuiling lifters, Koyo cam bearing, S&S tappet cuffs and an S&S performance intake manifold to replace the Harley plastic version. (do you have thoughts on any of these items? You also didn't mention the plastic intake manifold. Should I replace that as well? thanks again

[@DionRedBarronPercival]

Thanks for this update really appreciated I was so confused with all the hype around different parts that needed replacing you certainly know your stuff. Could I kindly ask you a question about the oil I should be using ina M8 I have a Harley fatboy 2022 only had it for five months still breaking it in 600 km so far have the standard dino oil that came with the bike. I’m thinking of using a synthetic just wondering if the SYN3 oil is what you use in theM8’s alternatively I was looking at Motul as I’ve had very good results with my Yz250 2 stroke and motul gear oil Sorry another oil question I know people hate this but I’m a bit confused as to what to use and would prefer an experienced person like yourself to comment as to what oil you put in the crankshaft primary and motor many thanks

[@MasterTechMiller]

The Harley Branded 20W-50 is absolutely fine to use. It's absolutely fine & I happily recommend it. If you want to spend the extra money on the SYN3 oil that's fine too. The FORMULA Plus oil for the Transmission & Primary is also absolutely fine to run.

Those 3 you mentioned will definitely prevent any premature problems or failures. There is a vent kit that can be done through the dealership that vents the primary housing to help prevent oil transfer problems.

When would you recommend upgrading the stock headbolts with heavy duty reusable headbolts from Screamin Eagle or S&S ? Would it make sense when installing the 131 kit with CR-512 cam only ? Thanks and greetings from Bangkok !

[@MasterTechMiller]

No it's not worth it for that kit. Nor is it worth it for most other big bore bolt on kits out there. The only time I would recommend them is on a boosted application or complete racing application where the engine is torn down and rebuilt frequently. To be honest the OEM ones are just fine.

Great information! I know this is a year old but I just bought a 17 Street glide with 46k miles on it, I believe it to be bone stock it has lifters/ tappers that leak down and rattle if you don’t ride it every day. I don’t want to go with a hotter cam I am old I just ride the bike on the highway driving the speed limit most of the time it has all the power I need! Would changing out the lifters with new screaming Eagle ones and the latest oil pump that’s out from Harley be the best way to know I am good to go? I think a new cam plate and cam would be inline so all he parts will get along in that cam chest am I think right or nuts? Thanks for what you do!

[@MasterTechMiller]

Yes, swap out your lifters for SE High capacity lifters & update your oil pump. That would be your best bet at this stage. Keep in mind, that if and when you decide to do a cam upgrade in the future you should always replace your lifters at the same time.

[@shaneverrall2807]

Do you need to upgrade the flywheel when going from 114 to 128kit ? Have you seen any of these fail ?

[@19Trent69]

Very informative.. cheers for sharing the knowledge.. With Lifters, how often should they be replaced, i.e in a twincam runnin se266.. ? Runnin procomp atm

[@MasterTechMiller]

The SE 266 cams require regular valve train maintenance and inspection as they are a high lift, high duration cam that puts larger stresses on the valve train. Depending of course on riding conditions (daily rider or more aggressive high rpm situations) I would suggest that the lifters be replaced every 20,000km for daily rider applications & around 8000km-10,000km for more aggressive riding styles. Keep in mind you should be able to have a decent understanding of what your engine sounds like & paying attention to it for any abnormal louder or growing noises should indicate cam chest & valve train inspection

[@19Trent69]

@Master Tech Miller too true.. have noticed alot more top end rattle ... normally change them at 30k, but have left them for 35k this time. Yer think it's time for a change.. besides the fact my base gaskets are leaking now hahaha.. I'll be doing fill gasket change, with check of cross hatch in bores( maybe redo with oversize rings).. thinking going solid lifters or fitting limiters to new set of hydraulic.. too much hitting rev limit... whoops lol

As have had the crank true and welded due to ruining the journals haha new rods were added . Runout at crank ( at cam plate) is 0.0008" New lifters, and possible another set of heads from Ram engineering, as these i have are for up to 107".. ( it's now a 117"). Has AV&V gear, gold valve guilds ect already.. Which is why I don't mind spending extra on it as it has good stuff, just not all the best..

[@robertmason8341]

You might get a reply if you actually took a minute to make your comment/question understandable! Punctuation goes a long way and correct spelling of key words would help a lot, such as you saying connect which I assume was supposed to be “correct” (as in asking the question)! Everyone understands when a typo or autocorrect jacks up something in a quick comment. But when you type out multi paragraph comments/questions then your implying it’s more serious and you’d actually like someone to read it/answer. That’s hard when your writing is all full of errors, lacks punctuation, and rambles along somewhat incoherently. It makes it “sound” like it’s coming from a kid and no one is gonna take that seriously! Not just ragging on you, I was really reading your comment and was gonna reply as I’m just as experienced with Harley’s and been working on motorcycles almost 30years.

Absolutely! Remove that SE498 & install the CR485 through www.alphaperformanceengines.com.au That will bring your 117ci to life!

[@m8_fanatic]

Awesome vid! I spoke to you several weeks ago about a stage 4 117 having a cr485 installed. Love the cam but i think it deserves some more cubes too! Whats your thoughts on the 128 vs 132 kit? I also asked for oil pump to be inspected when the cam went in, their answer was it looked updated as it had a rubber seal? Is this correct info? Im chasing 150/150 and am hoping with tge 485, 64mm tb, cnc ported heads and dnd bobcat i can get there

[@MasterTechMiller]

I would go with the 128ci kit over the S&S 132 as the cylinders are stronger in the 128. The rubber seal indicates an updated pump however it doesn't mean its the 8 lobe (like the one in the video). It had the rubber seal but still is a 10 lobe. You should be able to achieve 150/150 with a bump up in compression (around 11.5:1) in the 128ci kit with a good set of heads, exhaust & air filter. A good dyno tuner/operator is essential too.

Ok not that it’s a problem yet but I just found out this can cause some issues too and that is the long ass screws in the piston oilers just below the top of the crankcase coming loose and leaking causing a whole new cooling and oil supply issue . What is your take on that and a fix or has that since been corrected. I also have a 23 street glide special 114 in case you were wondering Thanks

[@MasterTechMiller]

I have NEVER seen this. I have heard of the idea getting tossed around back when the M8 engine first came out & they were having 'sumping' issues. Since late 2019 & on, all Harley's have the 8 lobe oil pump that has solved the sumping issue.

[@ashebarley77385]

when using the SE 131 kit would you use the rocker rollers or get from some other maker?

[@MasterTechMiller]

No need for roller rockers at all

On the compensator ramp, what’s your opinion on a stock one and leaving it alone on a 107 other than slip ones? Probably down the road thinking S&S 465, im no racer , do lots of miles, love to just ride, other than beating on it only a few times, for the most part just love to ride.

It's more than likely going to be fine to continue running the stock one in your case.

I’m building the 2023 lower rider st 1400 miles . I have a 475 in it now going to a 132 S&S and taking your advice and putting the Cycle-Rama 515 ( you suggestion) bigger valve springs , polished 55 mm manifold , 55 injectors , Thrash air cleaner , Thrash-in 2 into one pipe heavy clutch springs . Question can I use my S&S head bolts again only 600 miles on the build . I don’t do wheelies or burnouts . Not changing oil pump or cam plate or lifters . What is your thought , I have S&S push rods already .

[@MasterTechMiller]

I would be running the 64mm Throttlebody & Intake with that setup. I'm fairly sure the S&S head nuts & reusable so there shouldn't be a problem there. Your lifters should be fine at only 1400miles.

What do you think of the Dark Horse Man O War compensator?

[@MasterTechMiller]

I do not recommend it at all for street use. It stresses thr drive train far too much & you will have issues with belt failure, transmission problems (mostly with 3rd gear) your clutch will suffer excessive forces & overall it makes the bike feel harsh to ride. I only reccomend it to full race applications & where a welded Flywheel is used & the rest of the drive train has been upgraded to suit.

[@Manonymous108]

@@MasterTechMiller The build is a blue printed 124. Dark horse crank ( Balanced welded and trued), carillo rods, forged pistons S&S full cam chest, Bandit sportsman clutch with Trask billet clutch basket, Hayden primary tensioner Stage 3 cnc heads, Balanced injectors. Baker 7 speed transmission, in a '21 Ultra limited that is not going to the track. The build is being done by Keven Baxter and he recommended the installation of the man o war compensator. I'm not trying to be a dick, but I am fascinated by your reply and am curious if the compensator puts that much stress on the system that it would be more damaging to the build than helpful. The compensator is serviceable with cushioned pads, what is it about this compensator that you have seen in your experience that causes so much damage? There are a few builders here in the states that swear by its use, being that it is lighter and touted as stronger than other compensators. Some builders even put in a solid sprocket, but that sounds like it would do what you described the man o war compensator would do. They even advertise it (The man o war compensator) as having less shock to the system compared to a normal compensator. kzbin.info/www/bejne/nKDIh56Vrtqbabs

[@MasterTechMiller]

The last sentence in my replie states that I only recommend it in engines that are for full race applications & the drive train has been upgraded. You state that you have a complete build including transmission replacement & primary drive component upgrades. Even though you're not planning on going to the track to race it, your build would still fall under the 'full race' bracket.

[@Manonymous108]

@@MasterTechMiller OK I can't argue with your categorization, but these compensators are being installed on stock bikes and seemingly without any problems. The built in cushions would also seemingly allow some backlash in the drive train without causing problems as in a solid sprocket. Have you seem many stock bikes with this compensator have the problems you listed? I would really like to see some videos with this kind of information so that the general public could be informed. Also it would seem that even with the upgraded components, that IF such conditions exist in a stock motor, then they would exist in what you call a full race motor. Mechanical components will wear no matter how strong they are. Again I'm not trying to be a dick, I just want to be informed.

[@MasterTechMiller]

@Manonymous108 I will try to be clear. Yes some people are using it in stock bikes without any 'reported' problems. In saying that, the stock engine would not produce the same amount of huge torque a big inch build produces so therefore would not amplify the problems that can arise from removing the 'give' the OEM or billet compensator ramps allow for so yeah, some stock bikes would not have an issue. The little amount of cushion provided from the cushion drive in the Man O War compensator ramp does 'soften' the harshness from it but in my opinion and experience if you run that compensator on a big inch build with stock primary & transmission components then you will have problems in time. Maybe not for the first 10k miles but it will happen. If you wanna run that compensator with a full build that's fine, just know that when you strengthen one component you amplify the weakness of the next weakest component so that's why a 'full build is recommended

All oil pump & cam plate combos have to worry about run out. The SE unit has the biggest tolerance out of them all.

[@tennesseebound6597]

Can you upgrade to the SE oil pump and still use the stock cam plate or do you have to change to the new SE cam plate as a pair? Thank you

As a pair!

So I had my 131 installed and should they have put in adjustable pushrods? Cause they did not on my build and I put a tman air filter on and oil coming out the back plate which shouldn’t The spark plug on the front header doesn’t look like it’s being firing on the spark plug??? Advice ?

What’s your opinion on the plastic intake???

It's generally fine to use on all stage 2 kits. There are no issues with it that I am aware of. Most guys want it gone because it's plastic but that's about it. The benefits of the cast alloy units are that it is able to be port matched to the heads & the inner surface can be textures to help induce intake air tumble

[@MasterTechMiller]

The S&S 475 cam is a great all rounder cam that suits most people. However there are some trade off with it as it's so universal. Yes the Star 30/30 is a better cam than the 475 but there are much better bolt in cams than the 30/30 aswell. The CR485 is the best bolt in cam out there that I have ever installed, tuned & ridden on.

[@Dabocado]

That bearing you were talking about, is that the lefty bearing?

[@MasterTechMiller]

No. The inner cam bearing

[@Dabocado]

Thanks for clarifying that for me. My brand new LRS is in the shop getting built with a load of parts. I had ordered the lefty and the fellow was explaining it wasn’t needed to be installed. Not only that, it would be very labour intensive. I panicked because couldn’t remember what the well spoken man on the phone had said. I knew there was a super important bearing that needed to be installed. Anyway, I’m going with the right bearing. Thank you.

[@Big88Country]

Thanks Brother for all the great info! I have a 2017 CVO Ultra 114, completely stock except for pipes and better intake filter with only 6K miles. If this was your bike, would you spend the money to upgrade the oil pump? That's really all I'm worried about. Me and my wife are getting ready to start some long distance riding and it would suck to blow a pump in the middle of no where. What do you think? Thank you Sir, appreciate what you do for the motorcycle community!! New subscriber!!

[@MasterTechMiller]

I would definitely spend the money on upgrading the oil pump 100% without a doubt. Even though you already have 6k miles on it without any issues (yet) I would definitely replace it. If it was a Softail I wouldn't be too concerned but being a touring model I would not trust it. Long haul rising is a catalyst for the sumping issue. Don't get caught up in all the BS about aftermarket oil pumps & cam plates just the twin cooler 8 lobe oil pump fitted.
