The aftermarket and independent shops have quickly jumped all over what can be done with the M8, and H-D themselves have been going crazy with upgrades. It might not end up the next EVO, but it's already assured itself a long lasting future. There was disappointment with the TC for many. H-D came up with something that has panned out to be better with the M8 while still staying true to the air cooled 45 degree design. Some people hate change, but it was necessary to compete.

Great video. Probably the best MC channel.on TH-cam®️, with no fluff, BS, or juvenile stupidity. I've owned 10 Harleys in 51yrs, but I've pared it down to a '72 ElectraGlide I bought back in 1980, and a '97 WideGlide I bought 6yrs ago. You couldn't give me anything made after an Evo.
I've bought 4 brand new from the Dealer Milwaukee 8 bikes - 2018 Low Rider - 20 Sport Glide - 21 Street Glide Special - 23 Breakout . Put 32000 on the LR - 27000 so far on the 21 St Gl Special and haven't had a single problem with any of them . And I've ridden through some major desert heat long distance . All the bikes have been kept mainly bone stock . I am totally happy with the M8 motor , plenty of power and reliability .
I’m a lucky owner of a 2017 SGS. I had sumping issues, to the point of a lack of power, then an oil light. Went with an S&S oil pump/plate and zero issues. That 107 turned into a 124 and the oiling system works perfectly.
Hi GixxerFoo! I was watching this video on crap wrong with the m8. I have a 2018 road king. I have changed the oil pump, cam plate, 465c cam all s&s also a vented dip stick. I'm guessing now a vented tranny cover. This us my first harley wish I did some homework first but it is what it is. I do love the bike but I'm hearing noise from it seems like the primary. Do you know if there is any problems with the compensater on this bike? Thank you for your time!
1. It's not an oil pump issue, it's an oil drainage flow issue. Gravity feeds the oil pump oil. A restriction from an oil sump hole tapped too deep at the factory with a 1/2" NPT tapered plumbing tap, past the No Go line, causing a defect in the engine case's ability to drain the oil back to the oil pump. This causes the oil sump plug to be screwed in too deep, cutting off the oil drainage flow to the oil pump. Solutions are shortening/grinding down your oil sump plug 0.250" of an inch, or buying a Feuling shorty sump plug. My 2018 M8 107 Sport Glide has no issues ever with sumping and the stock oil pump, because my sump hole was tapped properly, not past the NO GO line, and the sump plug doesn't thread in too deep to the bottom of the engine case. It should fit barely flush or protrude somewhat. Teflon Plumbers tape can help, too, 5 or 6 wraps seating the sump plug more shallow. Box stock, I ride the torque, not the rpm's and HP. So far, very, very reliable, tons and tons of torque for a 695# softail. Ride's kind of rough and primitive, compared to my BMW R1250 GS, though.
I bought a 2017 ultra limited for 17,000 back in 2019 with 6,000 miles on it, I have installed myself the S&S 475 cam chest kit and a Thundermax ECM that I can download off of my lap top which made the tuning way easier for me without having to take it to the dealership. Also I installed a new head pipe with the larger bung hole connections for the thundermax O2 sensors, And a couple of DBX40 mufflers and that was it so far, love the bike the ride and comfort plus the power even stock was way better than my old EVO and Twin Cam bikes. I still own my 1986 FXSTC that I will never sell and that bike is what I ride mostly by myself the ultra is for me and my wife.
I own a 17 street glide special. Oil transfer was taken care of in first 5000 miles. It now has 34000 trouble free miles. I am very pleased with the performance and dependability! Note: it has a screaming eagle torque cam.....
I bought a used 2019 Trike and one of the first things I did was upgraded the oil pump, did a Jim's USA 819 cam, vented dipstick, went with an S&S intake, Tab pipes, and a nice air cleaner and had the whole thing dyno'd. She pulls like a beast now ... 103HP and 130TQ. No issues with oil sumping, overheating, or hard starts in the winter. Yeah I spent a lot, but considering the cost of a 2023 trike, it was worth it.
Hi, Harley rider and fan over 30 years here. This is mind blowing! I would have thought that after the TC88 debacle with the camplate etcetera this would not happen again. As far as I know there are no other companies in the world where you have to upgrade their (expensive) product at your own cost. Can anyone explain this please? Ride On💪... I'm still a fan of your informative videos!
I appreciate the support and always happy to help! I don't agree with Harley's business model at all, the parts in the engine off out of the factory aren't bad for what they are. Honestly a majority of people won't ever exceed or even come close to the breaking point of the stock engine internals. Harley does some great advertising and promotion of their "upgrades", do you need it, no. Do they hype you up and make you want it, absolutely!
I’ve followed your channel for sometime now, after this week’s video on the M8, I had already done all of you suggested upgrades on my 2019 Street glide special, I went with S&S 475, pump and plate, fueling vented dipstick was the first upgrade after I purchased this bike. Exhaust has also been changed out, headers and slip-ons, tuned with power vision. I have learned a lot about Harley’s from your channel. Keep it up man👍🏼
I bought a late 2019 had the oil transfer from gear box to primary right away it would transfer to the halfway point in the gear box where the clutch pushrod goes through than stay there . The dealer put in the vent tube in the primary under warranty. No other problems since, it just turned over 40k mi last month
1991 FLHS, 😊 ,I'm just going for a nice scenic putt on back country roads. I need reliability not that much horses. I don't use the 60hp the EVO generates and the torque is good enough also. I JUST RIDE 😊
I had a 2017 SGS; rode it 24,000 miles with absolutely no problems at all. City and urban driving and several multi day trips. Bike ran great with just a set of Cobra NH pipes. Currently have a 2020 SGS 114; great bike.
I bought a 2018 Road King Special. The motor started ticking at about 2,800 miles. I brought it in and they said it needed the Push Rods adjusted. At 3,200 miles the engine's top end was blown. Harley gave me a Stage 3 Screaming Eagle replacement. And kept the warranty at the 6 years I had worked out in my original agreement. I am Happy, needless to say.
I bought a 2018 Roadglide Ultra brand new. I have heard about all the problems but so far it runs perfect, just normal maintenance. I probably just jinxed it by saying that. Love the M8, it seems so much more responsive and powerful than my last bike that had the 96 cubic inch twin cam. Much smoother too.
Yes, my plan is as long as it continues to run good I'm going to leave it alone and enjoy it. If it ever starts to have problems that will be a good excuse to go in and do the whole S&S set up cams, cam plate oil pump pushrods etc. Thanks for your videos.
Def need to replace that oil pump. It's not about the examples of sumping, it's a completely faulty design, so the oiling system is not up to par on all that have it.
"Much smoother too" Why would you want smooth? If smooth is what you want, get a Goldwing. I have owned two Goldwings, and sold them both because they were just plain boring. Back in 2003, I got my first Harley, a 1989 FXRS Low Rider, in beautiful condition. I still have it. I absolutely love it. The sound and the feel is where the enjoyment of riding a Harley comes from. I rode Japanese cruisers for a long time before I was able to afford a Harley, albeit a used one. Night and day. I now have three EVO powered Harleys, my only Japanese bike is a Suzuki DR650 dual sport. I will never own any other street bike other than an EVO powered Harley.
I like having personal experience before speaking on something, kinda keeps one from looking foolish. The M8 has ton of personality, but the M8 is "smoother" than previous motors. Better throttle response, not to mention producing twice the evo's number with a little work. Who would buy the same bike after realizing it's "plain boring"?@@geraldscott4302
107 has been known to be great and reliable specially if you fix oil pump issue. I think they screwed up with the 114 as the cylinder sleeve was completely half the thickness and was breaking in chunks inside the crank area. There is a groove on the bottom of the cylinder sleeve and the jug. Haven’t heard anything good about the 114. I’ll probably buy an M8 within the next eight years but I’ll keep driving my late 90s Evo’s and my late 103‘s… there’s a pattern here, always wait five years before you buy the new engine…
That’s a new one. I’ve never heard anything about 114 cylinder sleeves. I currently have an Evo, TC and a 114 M8. Light years ahead of the others in my 40+ years experience.
Just to make it clear the trask vented transmission cover and the fueling vented dipstick do the same thing. They vent the crank case pressure to alleviate the oily air coming into the intake trough the breather hoses. The after market vented trans cover does not actually add venting to the transmission. There are 3 separate areas under the cover and one of them goes to the crankcase. I have the trask cover on my bike. These mods may help with sumping as it reduced the crank case pressure. And i can say it definitely helps with the oily intake air. edit: If i remember correctly on my 2023 stock trans cover there was already a little breather tube that i had to switch over to the trask one,this may be a trans breather. If you dont have this on the 17-19 bike then that might be beneficial to the trans/primary oil issue
I have a 2017 Road Glide with 46,000 miles that I put on. I have ridden this bike from Pennsylvania to Montana and back and have never had a problem. I did have the dealer do the primary vent early on.
I had a 2017 SGS with Cobra NH pipes and nothing else. Ran it for 24,000 trouble free miles. Now have a 2020 SGS 114 with the same setup; 12,000 miles no issues at all.
That's awesome to hear, I like to hear about the ones that don't have any issues and not all the M8's do. Are there problems, sure. But it's not every single engine out there that is going to fail.
Mines been solid. Ealry 2019 114 with 25k so far. All stock other than exhaust and tuner. No sumping. No oil consumption. The M8s mileage is quickly catching up to my Sportsters 50k+.
First thing I did on my 2018 was the whole cam chest and a great tune. Once I did the stage 4, I vented the dipstick, bike runs strong and barely throws any heat.
I upgraded my ‘19 RGU M8 to the Screaming Eagle torque cam and hi-cap gold oil pump and cam plate as a precaution and the engine runs solid with Rhinehart 4.5s. Plan is to make my first ever H-D a 100K bike. Well then see about an engine rebuild vs a crate. Love the added power the new cam and tune brought to the table!
I have ‘19 Ultra with 114. It has been a great engine, but I did do the S&S cam chest upgrade along with the Trask vented transmission cover after my brother had the sumping issue with his’19 RG Limited.
I bought a 2018 CVO street glide in Feb of 2023 with 5k miles and noticed sumping issue the first time I drove it like a crotch rocket. It Lost power had no clutch and ran fine when it cooled down. Local Harley service department had stupid look on their face when I brought in in for sumping. So I just bought a SE pro oil pump and 465 cam told them to put it in and it has ran fine every since then.
Is there a way we can get an oil shootout video from you for harley oils sinilar like project farm did for car oils? Amsoil, redline, maxima, mobil 1, Lucas, syn3, harley mineral, and formula +
I bought 2022 for all those reasons. But I do have trouble with cold starts. After sitting for a few weeks, in a cold garage at 40° it is like the battery is on its last leg, but after it warms up then all is good.
thanks, I always enjoy every video you make and how helpful you have been to us, I have a 2018, 107 that I bought new, and I had it change out last year to a screaming eagle upgrade and put a cam in the bike and oil pump, it didn't seem to have a problem but went with the upgrade anyway, and have taken long trips with the bike and it's been great, more power than I'll ever need. Thanks!!
Thank you for your support and I love to hear that! One little detail they don't often advertise about those billet cam plates and high volume oil pumps is the reduced rolling resistance over stock. They are more expensive to produce in quantity over the stock cast piece but overall so much better build quality goes into them.
I have seen issues with the Evos, oil lines that can leak like crazy, the lifter bores getting worn out etc. Have owned a built TC96 and now have a stg 2 M8114. Night and day difference between the M8 and anything prior.
Good advice...i have always waited for the most part for at least 4 or 5 years after the new stuff comes out to get it....98 Dyna,01 Road King ,and my current ride is a 14 Road king 103ho
The venting of the primary case, as standard from MY20 onwards, definitely stops the oil carry over from transmission to primary. The vented transmission however has nothing to do with solving this oil carry over, the transmission has been vented to ambient for ages already. This vent it is even the unlucky driving force behind the oil carryover to primary, so from MY20 solved by applying the same ambient pressure at the primary vent. That is the pressure equalizing, stopping oil carry over flowing through the hollow main shaft and passing the clutch push rod into the primary. What people mean with the vented transmisison cover is actually extra crank case venting (most of the time used to create open crank case ventilation to ambient, becasue they think it works against oil in the air filter with closed crank case ventilation) which indeed can run from an opening under the transmission cover connected to the crank case sump, from the factory originally separated from the transmission cavity (and ambient) by the cover rubber seal. On the CVO-121 engine, H-D even now themselves use this crankcase venting through the transmisson cover running with a rubber hose routing to the inlet manifold (still closed crank case ventilation, but possibly with less oil content when taken from this transmission cover location). The MY19 oil pump already has a modification with an O-ring on the pump cover, preventing pump suction air leakage, enabling better pump suction vacuum. The MY20 and later pump is even better in emptying the sump by optimizing the two parallel suction ports (from sump and from cam chain cavity) against the oil sumping risk.
Hey friend,I enjoy your videos that you put out every week.i was looking through some of your older videos about the heat problems that Harley had and how they dealt with them I was wondering if you remember way back when the engine would heat up and number two cylinder would shut down if you were in traffic or something and restarts after you got going again I guess that was a bad ideal probably was,I enjoy your videos keep up the good work thanks.🤓
Your tri glide is twin cooled, the twin cooled engines using the wet heads don't have an oil cooler. You can add an oil cooler in addition to the water cooled heads, which on a trike isn't a bad idea at all in my opinion.
I have a 2017 ultra low has 35,000 miles on it runs great has the water cooled heads can we get a video about the water cooled heads compared to the ones that do not have that and what problems they do and do not have in comparison to the ones without water cooled heads???
That's a great idea!! The twin cooling is quite a interesting subject and why they did it. There's a decent amount of difference there with only the heads cooled and the cylinders not having water jackets.
@@GixxerFoo I moved to Arizona so I’m planning to put a oil cooler on it but I’ve had no sumping issues oil cooler and external case breather are the first two things I plan on trying to get done to it
Hey Gixxer, watching your video like I always do and lo and behold , a pic of my bike pops up ! It’s the black ‘21 Lowrider S in my driveway. Very cool surprise although mine isn’t one with those issues 👍
Zero problems ! Thats an older pic. Running a Thunderheader, 22xe, PV-3B and an HPI air cleaner now. The bike rips ! Selling the T.H though. Just bought a Sawicki mid length in brushed stainless and the Advanblack ST fairing. Keep up the good work. Great channel.
Great video! You would think with the Twin Cam tensioner issue and lean APR that the MoCo would do better with the new M8 engine, but they did worse! I have lost all faith in the MoCo to do the right thing, all they are concerned with is cheaping out and not properly fixing the issues from the factory. This is inexcusable.
I have had two dealerships tell me they hardly ever see sumping issues and never see it on the M8 softail models. Only appears on touring models. I inquired about my 18 Fat Boy and changing out the oil pump. They said they would do it if I wanted but didn’t think it is necessary. Cost was to be roughly 1000 parts and labor. I said if it ain’t broke don’t fix it.
I have the first 2019 model limited here in the U.K. It wasn’t cheap, even as a used model. With already 35k mikes on it, it runs OK (I think). Admittedly I keep to the speed limits and ride like I can’t afford to repair it if It Implodes. Watching a lot of US made videos of ‘dudes’ thrashing their Harleys, no wonder they get fcuked up.
Hey what’s up man I watch every week I ride a twin cam fat boy I’m changing it to a 107 and I want your opinion on cams going with s&s 583. 585 or mr103 and that’s a 585 cam but comes on way sooner than the 585s same w the 583 they come on way sooner so I was curious what cam is best hole shot cam up to a quarter mile
I would tend to lead towards the MR103 or the 583, both have broader range down low and still leave plenty up top. the 585 pulls a little off the bottom and puts most of its peak up top.
Those are solid, they have the new style oil pump and they have the oil carryover from the transmission to the primary issue solved. I am still a strong supporter of the vented dip stick and trans cover on all M8 engines though.
Other that more than .005" crank run out, such that you have to run a chain drive cam, instead of gear driven, no. Practice some mechanical sympathy, and it should last you a long, long time. Hammer on it, and shit's gonna break, sooner, rather than later. Your breakout is a cruiser..... ride it like a cruiser. Ride the torque, not the HP on the motor.
again I have a 2018 m8 114 in a fatbob the supine issues are all on the touring models none with any of the soft tails not sure why I heard the oil ports are larger
I went with a low mileage used 2020 Road King. I would have considered an earlier year M8, but they didn’t seem to be discounted enough to factor in the cost of the oil pump upgrade. I also wouldn’t discount the benefit of running a high quality fully synthetic oil. Ride on!
Have you done anything on the Trask turbos ? I would love your opinion on it. They claim a 40% increase in horsepower over stock with their kit. I would really like to know what cost effective engine upgrades go well with the turbo and yes I am keeping my Twin cam 88 . Thanks
@@CactusJack252 when it comes to Evolution Sporster, yes it is. Even it's already decades, the whole construction of the engine is still the same with the 1986 evos
The problem with overlap from an emissions POV, is that raw fuel exits the engine while both valves are open. This means more hydrocarbons that the catalytic converter has to deal with. Left over exhaust gas in the cylinder is EGR. So if you are operating at 100 percent VE and 3 percent of that volume is EGR then your VE is actually 97 percent.
Hey brother, I got a question. I just bought my first harley a year ago a 23 roadglide special. Now I just picked up a 96 electraglide with evo motor. It has a carb on it. I wanna get a mikuni, but I don't know much about these motors, and I am no mechanic. My question is, what would I need for mods to get some good power remembering I got stock cases?? I don't want to spend thousands of dollars, but I will get what u recommend. I saw your video about the 83cu big bore kit. I got a 2-1 pipe and want the mikuni. What else would u recommend?? Any advise u got would be much appreciated. I'm thinking going 10:5:1 with the forged pistons and andrews ev 23 or 27 cam so what other components have u seen to get about 100hp and 100 tq
With an Evo Electra, I would put you a good free flowing exhaust (if it doesn't already have one). Put you an Andrews EV27 cam in there with a new set of lifters (they love to eat lifters around 40K). Get that carb jetted and dialed in, it will be whole new bike. They tend to make about 75 horse and 80-85 torque like that. Doesn't sound like much but they are so fun to ride you'll swear it's putting out more than what it really is.
I just bought a 2024 Street Bob to go along with my 75 FXE and my Evo Sportster. Never owned a fuel injected bike. What am I allowed to do or should do with it before the warranty runs out
My '21 M8 has starting issues at about 40 degree temperatures. To the best of my knowledge, there is no sumping problem, but it doesn't want to turn over when cold. This is dealer maintained with all HD syn fluids. Beyond that, I can't believe the difference between this motor and my '91 FXR Evo motor that I traded up from in '21.
Put the battery on a battery tender the night before you go riding. Should give you more ooomph at start up. Lithium FEO4 batteries don't do well in the cold, in the event you are running a Lithium battery. Stick to AGM's if you have cold weather startups.
@@feloniousmonk3049 Stock battery plugged into a Battery Tender whenever it's in the garage (every night, unless I'm on a road trip). I thin she's just cold hearted.
i replaced oil pump on my 2018 Heritage. never had issues but played it safe. you would have thought harley corporate would have paid for it as it was still under warranty but no.
Really on the fence about the Milwaukee 8. I hate all the electronics , traction control cornering control it’s way too much. I have a 2012 King 103 twin cam. I think the fit is better on that than the new ones full exhaust tuner and I have 79 hp and 115 foot pounds of torque just as good as Milwaukee 8. Oh, also fax tuner, which is best on the market completely replaces the brain in the bike
I really love my Evo Electra Glide Classic, but if I was going to go to a Milwaukee 8, I would go with a low mile 2017-2019 with a 107 and do a Fuel Moto 124 kit with a Wood 22XE cam and ported heads and a new tune. There would be nothing you couldn't do on that bike.
I have 40,000 km's on my 22 Heritage. 100% stock. Runs perfect. It never losses oil between my 8k oil changes. I'm also getting better than published fuel economy if I'm on the back roads. 4.4 liters /100km's, 53 mpg. Better than my 1200 Sportster. Tonnes of low end. So easy to brake that back wheel loose with a bit of throttle in first gear. Gets up to 160k so effortlessly.
That’s because you didn’t do these silly “upgrades “ that most guys do just for bragging rights. Keeping your bike stock or Stage 1 is the way to go. I did Pipes only & ride the balls off of it with no issues at all. All these guys have issues cause they can’t stop doing dumb shit to their bikes. These bikes have plenty of torque & power for street riding, stay safe out there!
The best thing you can do is leave your bike 100% stock. It will last a long, long time that way, probably 100k miles or more, if you don't abuse it, show some mechanical sympathy when the motor is cold, and service it by the book, every 8000 km with full synthetic 20w-50 in the crank and primary and gear box with gear oil as suggested in your owners manual. 3 hole oil is a joke, use proper oils in the gearbox and primary / clutch areas, not motor oil.
Thank you! That's a great idea! There's a lot of places you that sell suspension tailored to you specifically and it's actually waaaay less than just going Legends off the shelf. DK Customs is a great place to order yourself a suspension upgrade!
I own a 2020 FLTRX and i bought it brand new. I am 1st owner. the M8 has been junk from day one. From metal shavings in the crankcase, to transmittion problems to severely under powered, little to no torque, and i have 18k miles on it, and it needed to be completely overhauled around mile 1k. That is my 2nd harley davidson i have owned, and i will never buy another one.
Sorry to hear that. I bought a new 2021 FLTRX, have 30k on it and I’ve had no problems with it. I have kept it totally stock with no motor upgrades. Have a buddy with a 2022 that has a 114, we have ridden each other’s bike and found only a slight difference in power. Maybe yours was put together on a Friday afternoon before a 4 day weekend? Hope by now you have the bugs worked out. Hate to hear about someone having these problems on such a high priced motorcycle. I would be interested to know if you did any motor upgrades, stage 2 ect?

I’m surprised I haven’t heard of more complaints like yours. Given this is a HD issue and not a dealer issue.
M8´s honestly sounds pathetic straight off the showroom floor But with a proper cam and exhaust they do actually bring a good amount of that Harley-rumble that we all love
I don't give a rat's a$$ what they sound like. Grow the ef up and show some respect for your neighbors. Bright lights save lives, go buy some Denalis or Clearwater lights so you can be seen, not heard.
Because they are better engineered and extensive testing before making available to the public. HD should fix all those 17/18 year models with these inherent problems... I have not owned a HD in years but I like them, it's they are just too expensive all around...
You missed the simple fix for the tranny fluid crossover, a oversize diameter clutch actuating rod. (several makers out there, I use the shouldered ant not tapered style) Under a 100 bucks in most cases. done many, and so far it's the most efficient fix.
Do you think the Milwaukee 8 has the potential to be the next Evo with the right upgrades?
The aftermarket and independent shops have quickly jumped all over what can be done with the M8, and H-D themselves have been going crazy with upgrades.

I think the M8 is just like the Evo... Built for all the wrong reasons designed the wrong way.

Nothing beats an EVO.

Put 32000 on the LR - 27000 so far on the 21 St Gl Special and haven't had a single problem with any of them . And I've ridden through some major desert heat long distance . All the bikes have been kept mainly bone stock . I am totally happy with the M8 motor , plenty of power and reliability .

1. It's not an oil pump issue, it's an oil drainage flow issue. Gravity feeds the oil pump oil. A restriction from an oil sump hole tapped too deep at the factory with a 1/2" NPT tapered plumbing tap, past the No Go line, causing a defect in the engine case's ability to drain the oil back to the oil pump. This causes the oil sump plug to be screwed in too deep, cutting off the oil drainage flow to the oil pump. Solutions are shortening/grinding down your oil sump plug 0.250" of an inch, or buying a Feuling shorty sump plug. My 2018 M8 107 Sport Glide has no issues ever with sumping and the stock oil pump, because my sump hole was tapped properly, not past the NO GO line, and the sump plug doesn't thread in too deep to the bottom of the engine case. It should fit barely flush or protrude somewhat. Teflon Plumbers tape can help, too, 5 or 6 wraps seating the sump plug more shallow. Box stock, I ride the torque, not the rpm's and HP. So far, very, very reliable, tons and tons of torque for a 695# softail. Ride's kind of rough and primitive, compared to my BMW R1250 GS, though.
I bought a 2017 ultra limited for 17,000 back in 2019 with 6,000 miles on it, I have installed myself the S&S 475 cam chest kit and a Thundermax ECM that I can download off of my lap top which made the tuning way easier for me without having to take it to the dealership. Also I installed a new head pipe with the larger bung hole connections for the thundermax O2 sensors, And a couple of DBX40 mufflers and that was it so far, love the bike the ride and comfort plus the power even stock was way better than my old EVO and Twin Cam bikes. I still own my 1986 FXSTC that I will never sell and that bike is what I ride mostly by myself the ultra is for me and my wife.
I own a 17 street glide special. Oil transfer was taken care of in first 5000 miles. It now has 34000 trouble free miles. I am very pleased with the performance and dependability!
Note: it has a screaming eagle torque cam.....
Hope you get to 100 K subscribers.Very informative videos. Ride safe.
Thank you, I really appreciate that! That would be awesome to hit 100K, that would for sure be an accomplishment to share with everyone!
I bought a used 2019 Trike and one of the first things I did was upgraded the oil pump, did a Jim's USA 819 cam, vented dipstick, went with an S&S intake, Tab pipes, and a nice air cleaner and had the whole thing dyno'd. She pulls like a beast now ... 103HP and 130TQ. No issues with oil sumping, overheating, or hard starts in the winter. Yeah I spent a lot, but considering the cost of a 2023 trike, it was worth it.
Hi, Harley rider and fan over 30 years here. This is mind blowing! I would have thought that after the TC88 debacle with the camplate etcetera this would not happen again.
As far as I know there are no other companies in the world where you have to upgrade their (expensive) product at your own cost. Can anyone explain this please? Ride On💪...
I'm still a fan of your informative videos!
I appreciate the support and always happy to help! I don't agree with Harley's business model at all, the parts in the engine off out of the factory aren't bad for what they are. Honestly a majority of people won't ever exceed or even come close to the breaking point of the stock engine internals. Harley does some great advertising and promotion of their "upgrades", do you need it, no. Do they hype you up and make you want it, absolutely!
I’ve followed your channel for sometime now, after this week’s video on the M8, I had already done all of you suggested upgrades on my 2019 Street glide special, I went with S&S 475, pump and plate, fueling vented dipstick was the first upgrade after I purchased this bike. Exhaust has also been changed out, headers and slip-ons, tuned with power vision. I have learned a lot about Harley’s from your channel. Keep it up man👍🏼
Thank you! I am glad to hear you got that all taken care of already! That's gotta be an awesome ride!
Love my twin cam 103….
I bought a late 2019 had the oil transfer from gear box to primary right away it would transfer to the halfway point in the gear box where the clutch pushrod goes through than stay there . The dealer put in the vent tube in the primary under warranty. No other problems since, it just turned over 40k mi last month
1991 FLHS, 😊 ,I'm just going for a nice scenic putt on back country roads. I need reliability not that much horses. I don't use the 60hp the EVO generates and the torque is good enough also. I JUST RIDE 😊
I had a 2017 SGS; rode it 24,000 miles with absolutely no problems at all. City and urban driving and several multi day trips. Bike ran great with just a set of Cobra NH pipes. Currently have a 2020 SGS 114; great bike.
As much as you're paying for that Milwaukee 8 Harley-Davidson should put the shit on here for free
I bought a 2018 Road King Special. The motor started ticking at about 2,800 miles. I brought it in and they said it needed the Push Rods adjusted. At 3,200 miles the engine's top end was blown. Harley gave me a Stage 3 Screaming Eagle replacement. And kept the warranty at the 6 years I had worked out in my original agreement. I am Happy, needless to say.
My 2021 Road Glide Special needed new lifters at 25,000 miles. I went with S&S.
Another great informative video. Straight to the point, just the stuff a guy needs know. Thanks for continuing your work 👍🏻
I bought a 2018 Roadglide Ultra brand new. I have heard about all the problems but so far it runs perfect, just normal maintenance. I probably just jinxed it by saying that. Love the M8, it seems so much more responsive and powerful than my last bike that had the 96 cubic inch twin cam. Much smoother too.
That's the thing is just keeping up on the maintenance and a lot of these issues were like the Twin Cam problems, it didn't strike every single motor.
Yes, my plan is as long as it continues to run good I'm going to leave it alone and enjoy it. If it ever starts to have problems that will be a good excuse to go in and do the whole S&S set up cams, cam plate oil pump pushrods etc. Thanks for your videos.
Def need to replace that oil pump. It's not about the examples of sumping, it's a completely faulty design, so the oiling system is not up to par on all that have it.
"Much smoother too" Why would you want smooth? If smooth is what you want, get a Goldwing. I have owned two Goldwings, and sold them both because they were just plain boring. Back in 2003, I got my first Harley, a 1989 FXRS Low Rider, in beautiful condition. I still have it. I absolutely love it. The sound and the feel is where the enjoyment of riding a Harley comes from. I rode Japanese cruisers for a long time before I was able to afford a Harley, albeit a used one. Night and day. I now have three EVO powered Harleys, my only Japanese bike is a Suzuki DR650 dual sport. I will never own any other street bike other than an EVO powered Harley.
I like having personal experience before speaking on something, kinda keeps one from looking foolish. The M8 has ton of personality, but the M8 is "smoother" than previous motors. Better throttle response, not to mention producing twice the evo's number with a little work. Who would buy the same bike after realizing it's "plain boring"?@@geraldscott4302
107 has been known to be great and reliable specially if you fix oil pump issue. I think they screwed up with the 114 as the cylinder sleeve was completely half the thickness and was breaking in chunks inside the crank area. There is a groove on the bottom of the cylinder sleeve and the jug. Haven’t heard anything good about the 114. I’ll probably buy an M8 within the next eight years but I’ll keep driving my late 90s Evo’s and my late 103‘s… there’s a pattern here, always wait five years before you buy the new engine…
That’s a new one. I’ve never heard anything about 114 cylinder sleeves. I currently have an Evo, TC and a 114 M8. Light years ahead of the others in my 40+ years experience.
omg
Just to make it clear the trask vented transmission cover and the fueling vented dipstick do the same thing. They vent the crank case pressure to alleviate the oily air coming into the intake trough the breather hoses. The after market vented trans cover does not actually add venting to the transmission. There are 3 separate areas under the cover and one of them goes to the crankcase.
I have the trask cover on my bike.
These mods may help with sumping as it reduced the crank case pressure. And i can say it definitely helps with the oily intake air.
edit: If i remember correctly on my 2023 stock trans cover there was already a little breather tube that i had to switch over to the trask one,this may be a trans breather. If you dont have this on the 17-19 bike then that might be beneficial to the trans/primary oil issue
I have a 2017 Road Glide with 46,000 miles that I put on. I have ridden this bike from Pennsylvania to Montana and back and have never had a problem. I did have the dealer do the primary vent early on.
I had a 2017 SGS with Cobra NH pipes and nothing else. Ran it for 24,000 trouble free miles. Now have a 2020 SGS 114 with the same setup; 12,000 miles no issues at all.
That's awesome to hear, I like to hear about the ones that don't have any issues and not all the M8's do. Are there problems, sure. But it's not every single engine out there that is going to fail.
Mines been solid. Ealry 2019 114 with 25k so far. All stock other than exhaust and tuner. No sumping. No oil consumption. The M8s mileage is quickly catching up to my Sportsters 50k+.
I believe so. I have a 22 Trike and have did the S&S pump and plate, Zippers cam, trask vented transmission cover. It runs awesome!!
Non of these issues with my 64 panhead
Yep I'll keep my 49 El
Those were about as simple and easy to work with as it gets!
Thanks GF! I always learn something new by watching your videos. I'll mention this video to my neighbor, who bought a new FLHX in 2017.
Thank you for supporting the channel! Glad I can help!
Love my evo.
First thing I did on my 2018 was the whole cam chest and a great tune. Once I did the stage 4, I vented the dipstick, bike runs strong and barely throws any heat.
Good infor but ill keep my twin cam hot rod.
When you got a Twin Cam setup like that they will do just about anything you can make the M8 do.
I owned 3 twin cam bikes. Last one was heavily modded and my new 23 RG-ST with factory cam smokes it. M8 is a better motor.
@@Prometheus1979 that's your opinion
Same here ✌️
Who rather have a twin cam over the M8 let's get it goin
I upgraded my ‘19 RGU M8 to the Screaming Eagle torque cam and hi-cap gold oil pump and cam plate as a precaution and the engine runs solid with Rhinehart 4.5s. Plan is to make my first ever H-D a 100K bike. Well then see about an engine rebuild vs a crate. Love the added power the new cam and tune brought to the table!
A cam and a good tune will transform a motorcycle entirely!
Have a 2021, street glide standard, love it!
I have ‘19 Ultra with 114. It has been a great engine, but I did do the S&S cam chest upgrade along with the Trask vented transmission cover after my brother had the sumping issue with his’19 RG Limited.
I bought a 2018 CVO street glide in Feb of 2023 with 5k miles and noticed sumping issue the first time I drove it like a crotch rocket. It Lost power had no clutch and ran fine when it cooled down. Local Harley service department had stupid look on their face when I brought in in for sumping. So I just bought a SE pro oil pump and 465 cam told them to put it in and it has ran fine every since then.
Is there a way we can get an oil shootout video from you for harley oils sinilar like project farm did for car oils? Amsoil, redline, maxima, mobil 1, Lucas, syn3, harley mineral, and formula +
I bought 2022 for all those reasons. But I do have trouble with cold starts. After sitting for a few weeks, in a cold garage at 40° it is like the battery is on its last leg, but after it warms up then all is good.
thanks, I always enjoy every video you make and how helpful you have been to us, I have a 2018, 107 that I bought new, and I had it change out last year to a screaming eagle upgrade and put a cam in the bike and oil pump, it didn't seem to have a problem but went with the upgrade anyway, and have taken long trips with the bike and it's been great, more power than I'll ever need. Thanks!!
Thank you for your support and I love to hear that! One little detail they don't often advertise about those billet cam plates and high volume oil pumps is the reduced rolling resistance over stock. They are more expensive to produce in quantity over the stock cast piece but overall so much better build quality goes into them.
2019 Road King bought with 6k on it. put 5k on it this riding season no issues was stock now has tab 50cal zombie pipes.
I'll stick with my twin cam 103 HO. Best engine out there.
I agree tc for prez
Same
I have seen issues with the Evos, oil lines that can leak like crazy, the lifter bores getting worn out etc. Have owned a built TC96 and now have a stg 2 M8114. Night and day difference between the M8 and anything prior.
Good advice...i have always waited for the most part for at least 4 or 5 years after the new stuff comes out to get it....98 Dyna,01 Road King ,and my current ride is a 14 Road king 103ho
What’s the thought on making a 117 to a Harley 131 ??
Any drivability issue ??
My 2022 streetglide special with 29k is in the shop for piston slap and lifter. Glad it's still under warranty
The venting of the primary case, as standard from MY20 onwards, definitely stops the oil carry over from transmission to primary. The vented transmission however has nothing to do with solving this oil carry over, the transmission has been vented to ambient for ages already. This vent it is even the unlucky driving force behind the oil carryover to primary, so from MY20 solved by applying the same ambient pressure at the primary vent. That is the pressure equalizing, stopping oil carry over flowing through the hollow main shaft and passing the clutch push rod into the primary.
What people mean with the vented transmisison cover is actually extra crank case venting (most of the time used to create open crank case ventilation to ambient, becasue they think it works against oil in the air filter with closed crank case ventilation) which indeed can run from an opening under the transmission cover connected to the crank case sump, from the factory originally separated from the transmission cavity (and ambient) by the cover rubber seal. On the CVO-121 engine, H-D even now themselves use this crankcase venting through the transmisson cover running with a rubber hose routing to the inlet manifold (still closed crank case ventilation, but possibly with less oil content when taken from this transmission cover location).
The MY19 oil pump already has a modification with an O-ring on the pump cover, preventing pump suction air leakage, enabling better pump suction vacuum. The MY20 and later pump is even better in emptying the sump by optimizing the two parallel suction ports (from sump and from cam chain cavity) against the oil sumping risk.
Hey friend,I enjoy your videos that you put out every week.i was looking through some of your older videos about the heat problems that Harley had and how they dealt with them I was wondering if you remember way back when the engine would heat up and number two cylinder would shut down if you were in traffic or something and restarts after you got going again I guess that was a bad ideal probably was,I enjoy your videos keep up the good work thanks.🤓
It still has that feature with the milwaukee 8 motors.
You talk about that the oil cooler came on stock. I got a 2022 tri glide ultra where is the oil cooler on them?
Your tri glide is twin cooled, the twin cooled engines using the wet heads don't have an oil cooler. You can add an oil cooler in addition to the water cooled heads, which on a trike isn't a bad idea at all in my opinion.
I have a 17...107 haven't had any problems . But at around 12,000 mile I added a s&s cam with the new updated Harley oil pump
I have a 2017 ultra low has 35,000 miles on it runs great has the water cooled heads can we get a video about the water cooled heads compared to the ones that do not have that and what problems they do and do not have in comparison to the ones without water cooled heads???
That's a great idea!! The twin cooling is quite a interesting subject and why they did it. There's a decent amount of difference there with only the heads cooled and the cylinders not having water jackets.
@@GixxerFoo I moved to Arizona so I’m planning to put a oil cooler on it but I’ve had no sumping issues
oil cooler and external case breather are the first two things I plan on trying to get done to it
My buddy had this sumping issue on his 2017 M8. Motor was spewing oil out of the air cleaner.
Evo👍
Hey Gixxer, watching your video like I always do and lo and behold , a pic of my bike pops up ! It’s the black ‘21 Lowrider S in my driveway. Very cool surprise although mine isn’t one with those issues 👍
That's awesome!! That's a cool looking bike!! What kinda problems are you having with it?!
Zero problems ! Thats an older pic. Running a Thunderheader, 22xe, PV-3B and an HPI air cleaner now. The bike rips ! Selling the T.H though. Just bought a Sawicki mid length in brushed stainless and the Advanblack ST fairing. Keep up the good work. Great channel.
Great video! You would think with the Twin Cam tensioner issue and lean APR that the MoCo would do better with the new M8 engine, but they did worse! I have lost all faith in the MoCo to do the right thing, all they are concerned with is cheaping out and not properly fixing the issues from the factory. This is inexcusable.
There's some issues out there with them for sure, but they are getting better and the aftermarket is always way ahead of the game.
I have had two dealerships tell me they hardly ever see sumping issues and never see it on the M8 softail models. Only appears on touring models. I inquired about my 18 Fat Boy and changing out the oil pump. They said they would do it if I wanted but didn’t think it is necessary. Cost was to be roughly 1000 parts and labor. I said if it ain’t broke don’t fix it.
I own both, tc dyna tc road king, m8 107 king and m8 131 electra. The twin cams vibrate, might leak, but they RUN.
The never ending issues of the HD V Twin ,.................will they ever get it Right ?
120 years of engineering, unimpeded by progress.
I ceep my TC 88 from 2002. It's good enough for me
I have the first 2019 model limited here in the U.K. It wasn’t cheap, even as a used model. With already 35k mikes on it, it runs OK (I think).
Admittedly I keep to the speed limits and ride like I can’t afford to repair it if It Implodes.
Watching a lot of US made videos of ‘dudes’ thrashing their Harleys, no wonder they get fcuked up.
Hey what’s up man I watch every week I ride a twin cam fat boy I’m changing it to a 107 and I want your opinion on cams going with s&s 583. 585 or mr103 and that’s a 585 cam but comes on way sooner than the 585s same w the 583 they come on way sooner so I was curious what cam is best hole shot cam up to a quarter mile
I would tend to lead towards the MR103 or the 583, both have broader range down low and still leave plenty up top. the 585 pulls a little off the bottom and puts most of its peak up top.
2019 Slim all stock no problems. May do a cam, oil pump ,plate this winter?
Cam will make it a whole new bike!
@@GixxerFoo we can't let the EPA ruin all the fun lol
I have a 2023 Breakout with the 117 M8. I assume I have nothing to worry about.
Those are solid, they have the new style oil pump and they have the oil carryover from the transmission to the primary issue solved. I am still a strong supporter of the vented dip stick and trans cover on all M8 engines though.
Other that more than .005" crank run out, such that you have to run a chain drive cam, instead of gear driven, no. Practice some mechanical sympathy, and it should last you a long, long time. Hammer on it, and shit's gonna break, sooner, rather than later. Your breakout is a cruiser..... ride it like a cruiser. Ride the torque, not the HP on the motor.
Great videos gix
Thank you! We appreciate the support!
again I have a 2018 m8 114 in a fatbob the supine issues are all on the touring models none with any of the soft tails not sure why I heard the oil ports are larger
That is true! The touring bikes had all the issues, very very rarely do you see an anomaly in the Softail having issues.
@@GixxerFoo Maybe those were Kansas City built bikes, not York, PA
I went with a low mileage used 2020 Road King. I would have considered an earlier year M8, but they didn’t seem to be discounted enough to factor in the cost of the oil pump upgrade. I also wouldn’t discount the benefit of running a high quality fully synthetic oil. Ride on!
I love my Panhead
Seems crazy a 30-40k motorcycle needs another 10 k in aftermarket parts to make it reliable
I always said that and then again ty here performance cars that are 60 to 100K with a huge aftermarket to make them even better.
Have you done anything on the Trask turbos ? I would love your opinion on it. They claim a 40% increase in horsepower over stock with their kit. I would really like to know what cost effective engine upgrades go well with the turbo and yes I am keeping my Twin cam 88 . Thanks
Aight, I'll keep my TC 88.
I’m keeping my 2019 iron 1200. I have over 20k on it and it has been extremely reliable
@@CactusJack252 when it comes to Evolution Sporster, yes it is. Even it's already decades, the whole construction of the engine is still the same with the 1986 evos
Shovelheads forever !!!!!
😎👍
Big thumbs up for the channel...
Thank you! Cheers!
Thanks for another great, and informative installment. 👍
The problem with overlap from an emissions POV, is that raw fuel exits the engine while both valves are open. This means more hydrocarbons that the catalytic converter has to deal with. Left over exhaust gas in the cylinder is EGR. So if you are operating at 100 percent VE and 3 percent of that volume is EGR then your VE is actually 97 percent.
Well done lad! How about a video on catch cans?
It's an older video but a goodie! th-cam.com/video/3plS6M0_Bdc/w-d-xo.html
Hey brother, I got a question. I just bought my first harley a year ago a 23 roadglide special. Now I just picked up a 96 electraglide with evo motor. It has a carb on it. I wanna get a mikuni, but I don't know much about these motors, and I am no mechanic. My question is, what would I need for mods to get some good power remembering I got stock cases?? I don't want to spend thousands of dollars, but I will get what u recommend. I saw your video about the 83cu big bore kit. I got a 2-1 pipe and want the mikuni. What else would u recommend?? Any advise u got would be much appreciated. I'm thinking going 10:5:1 with the forged pistons and andrews ev 23 or 27 cam so what other components have u seen to get about 100hp and 100 tq
With an Evo Electra, I would put you a good free flowing exhaust (if it doesn't already have one). Put you an Andrews EV27 cam in there with a new set of lifters (they love to eat lifters around 40K). Get that carb jetted and dialed in, it will be whole new bike. They tend to make about 75 horse and 80-85 torque like that. Doesn't sound like much but they are so fun to ride you'll swear it's putting out more than what it really is.
I just bought a 2024 Street Bob to go along with my 75 FXE and my Evo Sportster. Never owned a fuel injected bike. What am I allowed to do or should do with it before the warranty runs out
I was considering a new 2019 Sport Glide. I am glad I went with a Guzzi instead. It was cheaper also.
My '21 M8 has starting issues at about 40 degree temperatures. To the best of my knowledge, there is no sumping problem, but it doesn't want to turn over when cold. This is dealer maintained with all HD syn fluids. Beyond that, I can't believe the difference between this motor and my '91 FXR Evo motor that I traded up from in '21.
Put the battery on a battery tender the night before you go riding. Should give you more ooomph at start up. Lithium FEO4 batteries don't do well in the cold, in the event you are running a Lithium battery. Stick to AGM's if you have cold weather startups.
@@feloniousmonk3049 Stock battery plugged into a Battery Tender whenever it's in the garage (every night, unless I'm on a road trip). I thin she's just cold hearted.
i replaced oil pump on my 2018 Heritage. never had issues but played it safe. you would have thought harley corporate would have paid for it as it was still under warranty but no.
Harley isn't gonna fix their own mistakes!
How much did that cost you?
@@sstyx8 i cannot remember. i did it 5 years ago.
I am looking at buying a 2022 Soft Tail standard with a 475 cam, or a stock 2023 Street Bob 114, any advice on which motor ?
Dont Forget Piston Jets. My 2018 Heritage had them go out and junk the engine. Good thing Im saving for a 131.
Glad I waited till 2020 to buy my Road King!
That’s why I waited to purchase until 2021.🏍💨🏍💨
whats all that cost
Really on the fence about the Milwaukee 8. I hate all the electronics , traction control cornering control it’s way too much. I have a 2012 King 103 twin cam. I think the fit is better on that than the new ones full exhaust tuner and I have 79 hp and 115 foot pounds of torque just as good as Milwaukee 8. Oh, also fax tuner, which is best on the market completely replaces the brain in the bike
Yup my 2018 RKS oil pump sumped and blew engine 2 weeks ago. $5K out of pocket to repair. Bye HD never again.
Whoa!! Sorry to hear that, that sucks. Did you fix it and sell or are you keeping the bike?
I really love my Evo Electra Glide Classic, but if I was going to go to a Milwaukee 8, I would go with a low mile 2017-2019 with a 107 and do a Fuel Moto 124 kit with a Wood 22XE cam and ported heads and a new tune. There would be nothing you couldn't do on that bike.
I have 40,000 km's on my 22 Heritage. 100% stock. Runs perfect. It never losses oil between my 8k oil changes. I'm also getting better than published fuel economy if I'm on the back roads. 4.4 liters /100km's, 53 mpg. Better than my 1200 Sportster. Tonnes of low end. So easy to brake that back wheel loose with a bit of throttle in first gear. Gets up to 160k so effortlessly.
That’s because you didn’t do these silly “upgrades “ that most guys do just for bragging rights. Keeping your bike stock or Stage 1 is the way to go. I did Pipes only & ride the balls off of it with no issues at all. All these guys have issues cause they can’t stop doing dumb shit to their bikes. These bikes have plenty of torque & power for street riding, stay safe out there!
The best thing you can do is leave your bike 100% stock. It will last a long, long time that way, probably 100k miles or more, if you don't abuse it, show some mechanical sympathy when the motor is cold, and service it by the book, every 8000 km with full synthetic 20w-50 in the crank and primary and gear box with gear oil as suggested in your owners manual. 3 hole oil is a joke, use proper oils in the gearbox and primary / clutch areas, not motor oil.
Wow , you seem to Come up With alot of Good Topics. How about Something that using Frt. & Rear Shock Upgrades that is Not Breaking The Bank !!!!
Thank you! That's a great idea! There's a lot of places you that sell suspension tailored to you specifically and it's actually waaaay less than just going Legends off the shelf. DK Customs is a great place to order yourself a suspension upgrade!
I own a 2020 FLTRX and i bought it brand new. I am 1st owner. the M8 has been junk from day one. From metal shavings in the crankcase, to transmittion problems to severely under powered, little to no torque, and i have 18k miles on it, and it needed to be completely overhauled around mile 1k. That is my 2nd harley davidson i have owned, and i will never buy another one.
Sorry to hear that. I bought a new 2021 FLTRX, have 30k on it and I’ve had no problems with it. I have kept it totally stock with no motor upgrades. Have a buddy with a 2022 that has a 114, we have ridden each other’s bike and found only a slight difference in power. Maybe yours was put together on a Friday afternoon before a 4 day weekend? Hope by now you have the bugs worked out. Hate to hear about someone having these problems on such a high priced motorcycle. I would be interested to know if you did any motor upgrades, stage 2 ect?
@@jacksidney3907 the bike has been 100% bone stock with the 107 ci no upgrades. the warranty gave me some BS run around and denied any claim, glad i never got the extended warranty. i got the same BS warranty issue crap on my 1st bike too
@@rigobertoalbarran9242
Oh damn it, I got the extended warranty on my 107. I haven’t had any warranty claims yet, sure hope I won’t have to test them. If I do and it’s something the warranty states it covers, I’ll simply stop paying the note on it then immediately file a lawsuit for breach of contract.
They keep acting like a holes on a legitimate warranty claim they will destroy their company.
Feel for you though, disappointed to hear of your experience. I’m surprised I haven’t heard of more complaints like yours. Given this is a HD issue and not a dealer issue.
Dont give up on Harley, just give up on the Motor Company and use the after market as I have.
M8´s honestly sounds pathetic straight off the showroom floor
But with a proper cam and exhaust they do actually bring a good amount of that Harley-rumble that we all love
I don't give a rat's a$$ what they sound like. Grow the ef up and show some respect for your neighbors. Bright lights save lives, go buy some Denalis or Clearwater lights so you can be seen, not heard.
To me, sumping feels like running from the beach to the lake, you get in deep enough and you're working a lot harder but moving a lot slower
That's basically exactly what it is, that sump slowly takes on oil and leaves the crank treading through the liquid.
They've been building motorcycles for over 120 years and they still can't get it right. But that's OK. The customer will fix it.
Why don't the other brands have these problems?
Because they are better engineered and extensive testing before making available to the public. HD should fix all those 17/18 year models with these inherent problems... I have not owned a HD in years but I like them, it's they are just too expensive all around...
I've figured out how to beat an EVO. Two EVOs!😅
Thank you for saying engines instead of motors I'm old school
You missed the simple fix for the tranny fluid crossover, a oversize diameter clutch actuating rod. (several makers out there, I use the shouldered ant not tapered style) Under a 100 bucks in most cases. done many, and so far it's the most efficient fix.
