Keenan i have been watching your channel fo years now.... I still have the series you did on your buddies Twink 110.. cause it helped me rebuild my motor..
I admire and respect your years of knowledge...It still works even with new stufffff that is being used now
fix it correctly and they will last. no matter how bad the design was.
tatro
Thank-You for the info. I have an unmolested 2020 107" with no problems that's pushing her seventh oil change. Good luck with your endeavours.
I'm actually really fucking excited Tatro is busting into M8s! I hope you continue to work on these... It'd be awesome to see what you could do with these M8s! They can make alot of power even more with the Tatro touch!
Keenan hates anything later than Evo's LOL
man if Tatro sat down with a Harley engineer id love to listen to that conversation. Tatro's truth.
🤣 Yeah, that would be very interesting. Sadly they don't give a rats ass though. I wouldn't buy anything new even if it was 1/3 of their asking price. I just can't believe the junk leaving the factory! I've been brand loyal my whole life and honestly think that Polaris has a way better product
Thks Tatro. Black plastic piece with o ring siting on top of cylinder head, kind of breather.
oh, you mean that one that barly works to stop the wet sumping.
tatro
These videos are getting back to normal.
all scrwed up again and throwing crap around. oh, and you can't hear me.
tatro
@@TatroMachine No. You doing what you do best. Working on motors!
By the way, It was great watching you trying to figure out what the f that rocker box breather was!!! 😝
Solid autopsy. Thanks!
now should i show them how to save all the junk parts and reuse them again. oh yea, they didn't like those videos.
tatro
@@TatroMachine That's their problem 👌
Man , every time I see an M8 engine break down, there’s evidence that Harley did a poor job on the machining. I wonder if the M8 is actually a good engine if Harley would of done better quality control?
Nice breakdown of the loctite
Great insight. I would not have believed it if I had not seen it.
Hey Tatro, do you still have that m8 balancer you said you guys were going to be leaving out in this build? I could really use that bad, I got a blown up m8 some metal ran thru that backlash elimination gear and the stationary gear on it and now it’s bent over so slightly and causes a tight spot when trying to spin the engine over. Let me know if you’d let go of it and have time to ship it I can drop you some $…thanks bro
Keenan, check the service bulletin on those piston oilers. I think there was something about the bolts being too long, causing an oil pressure problem?
i don't need seriver bulletins. i can tell that crap when i put things togethere. its called, paying attention to the details. that is why some mechanics motors run better and last longer while useing the same parts as the other guy.
tatro
Has Harley ever made anything that isn't crap or junk? I've been interested in owning one for a long time but videos like these reinforce the reputation that Harley has earned over the decades. Back in the day everyone said "Buy a Harley, buy the best, ride a mile, walk the rest." I guess nothing has changed. I'll stick to my metric cruiser I guess.
harleys are like an old truck. they will take a ton of abuse and keep going no matter what. this leaves lots of room for improvements to make it what you want it to be. harleys makes changes over decades so you have a very large parts mix to play with to make it your own. it is very hard to beat that with anyother manufacture.
tatro
Harley makes a good product overall. But if you modify it you will be asking for trouble with the newer twin cam and M8 models. Leave it stock and it will be fine, despite the cheap short cuts and cost cutting measures shown here. Modern manufacturing does put any thought into rebuilding. It is a throw away world. I don't like it but that is the way it is, cars, trucks, motorcycles, what ever. This engine had aftermarket performance parts installed, engine life was shortened. If you like hot rodding your engine, modifying it yourself, trying new ways, get an evo.
I think I’ll stick with me knuckles, lol
21st Century Basket Case....came in a "high quality" plastic tote! LOL🤣
I never noticed any screws in the timing side case on my 2010 Dyna, but then it was made July '09..... nice to know that Harley's latest piece of crap is as bad as the one before ! I suppose it's only a matter of time before someone brings you a new Sportster......
Good morning
I left the compensators out of my 88 TC, no way could I get the bearings out, so I just left them in, I'm sure I'll notice if they finally come out
Tatro is the crank in the 88 twin cam any good man or all they all junk?...I bought a used road king turd that has fueling cams in it. Is everything made today for these engines junk?...pretty much
all stock harley cranks are junk. use the s&s or ultima cranks. they are both good and will take alot of abuse. like most harley motors. if you replace enough of the junk har;ey parts you start to get a fairly good motor.
tatro
@@TatroMachine Great advice Keenan, I took your advice and put an Ultima Flywheel assembly in my Evo and have never been happier
Have a nice weekend 🤗 😊 😄 😁 💕
The phone ringer sounds like a casino slot machine. I hope your winning.
i am still breathing so things can't be all that bad.
tatro
@@TatroMachine Every day I'm above dirt and on my hind legs , it's a win.
Beware of the balance shaft bearings in the crankcase , they are cheapass made in India bearings with plastic cages . I rebuilt one last year , the cage failed and plastic debris circulated throughout the engine , plugging crucial oil passages . It was a mess and getting replacement bearings at the time was a shit show.
just go buy the steel caged versions of the bearings. harley is not the only place to buy harley parts.
tatro
@@TatroMachinedo you have part numbers for those bearings?
They save money on all everything they can, but they don't pass any of that savings on to the customer, the price tags on these new bikes will scare the shit out of you. I'm not ever gonna pay for a motorcycle, what I should pay for a pickup.
they are up to 80k now.
tatro
Tatro do you prefer the twincam over the M-8?
m8 heads suck in many ways. i will stay with a good set of oval port evo heads.
tatro
I have a 2013 twincam, the compinsator is gone out. I ordered a dark horse comp to replace it. I called harley and they told me that compinsators were obsolete for my bike. Thus why I bought the dark horse costom compinsator. About 200 dollars more than the original. Iam very disappointed that harley didn't stick with it and come up with a fix for my bike. My ironhead has kept me in the wind though.
so much for harley supporting their bikes. i am sure they can set you up with a nice new m8 and a new harley jacket.
tatro
I think the part number was super ceded. You cannot buy the exact unit that came on your bike. It’s upgraded. SE comp
Who welded the crank pin? Is Harley doing that now?
no, someone spent a ton of money on this motor and than it went all to hell because they did not assemble it correctly. slow down and pay attention. it will save you in the long run.
tatro
Why the he'll do people take shit apart, then bring it to you to fix and put back together?
that would be the other mechanic. that so called expert you have working on your bike might not be all that good after all. we all have to learn on something.
tatro
When all else fails, take it to the pro.
@@ec3489 I understand that, but why fuck with it in the first place? This should cost more then if you just brought it in, in one piece.
Good morning, is the inner cam
Bearing recessed? Looks like it set down into the case .0100 or so? Should be about flush? Or is it just an optical allusion?
no, harley has a big chamfer and you need to be past that to be into the bore.
tatro
Hey tatro, do you put loctite 638 on valve seals? I remember in another you put some green loctite on some seals, but I’m not sure if it was 638 or something different.
yes i loctite them on. it was a different number. they have lots of new numbers to choose from now. get a high heat one.
tatro
Hi Mr.Tatro! What loctite number I need for assembly Evo flywheel? (for crankpin nut)?
i just showed you a bunch of the new ones i got.
tatro
That crap sucks like walker 😕 this is exactly why we need more ironhead stuff
Noticed the crank pin was welded.... your work ?
no, i don't weld cranks. buy a good crank from s&s or ultima and you don't have to screw around doing stupid stuff like that.
tatro
80 cubic inch Evolution was their best. Turn the key press the button and go.
that would be correct.
tatro
I've scissored 2 Evo flywheels already, doesn't mean they're all that but still...
Only thing that I see as a possible "improvement" is the non drive side bearing is able to be replaced thus eliminating any need for case race lapping requirements. Obviously the elimination of the Timken on the drive side was and forever will be a dumb move.
the key is to have the larger roller size. to make room for that everything else had to be changed.
tatro
@@TatroMachine yes. Agreed and it looks like they managed to do that
I think that the old stuff is way better quality than this rubbish, I can't believe they dont run bushes in the rods.
,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,save a dollar,,,,screw the product life,,,,,,,,,,trade it in every year,,,,,,that's the dealer way...................fuk new shit.......................
Harley made a good engine with the early evo so why would they make more power with an engine that looks like when they fail it will be a big fail.
the 90's cheap ass evo cranks sucked too. leave it to the aftermarket to make the good parts.
tatro
Are they built that cheap, lol
,,,,I need a set of old 1978,,,,,S & s steel stroker wheels,,,,4 . 625 inch stroke......have anything,,,,,I'd rather pay you than truett and Osborne........?????
nope. find a good s&s set on ebay. those other ones suck.
tatro
@@TatroMachine ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,thanks tatro..........................
Maybe plastic pollution device 😂
2020 engine and already toast? What a piece of crap. Thank God I have a 80 evo, they run almost forever.
A hack installs the cam bearing without checking to see if it's rolling freely, while installing numerous other aftermarket parts and it's HD's fault?
@@jefferythomas4414 yeah, the M8 is without a doubt the best motor EVER
is your ass on fire for that one.
tatro
@@TatroMachine I made that comment with sarcasm, ain't no way the M8 is even considered to be the best motor ever. I think the Flathead was...
First, good morning
Looks like a cheap Chinese knock off engine. Yuck
You probably wish you had a M8
To much Valve Spring Tension on 1 cam with inferior bearings...Another Better Mouse Trap Idea...P.O.S.
i am not seeing that but that can be some of it. the good cam bearing was installed wrong forsure.
tatro
Too much on one cam , exactly what I thought , most people dont think about this either , the more duration the cam has the steeper the duration angle , that flat duration face coming at the lifter roller is sudden shock and will cause the lifter bores to wear faster and get loose , it has no choice , its a aluminum motor block , aluminum can not take the stress a cast iron motor block can take , doesnt matter if its a single or twin cam the lifter bores take a beating , thats my opinion and Im sticking with it .......
I know you're not a fan of the EVOLUTION motors, but one look at the inside of an M-8, I'm glad I kept what I had. Harley is just screwing their customers with cheap crap. I don't understand why people are still buying this junk. Its one thing to buy a new motorcycle, then decide to modify it, but this garbage needs thousands of dollars worth of work just to keep it running.
Amen, same thing I said. I wouldn't want anything new AT ALL!!! GARBAGE
is that the short line or the long line you are standing in.
tatro
typical modern manufacturing found in almost all brands now. it is a throw away world and I don't like it one bit! Cheap parts, cheap assembly, get it out the door, replace components, repair/rebuild nothing
Bang smash crash no wonder nothing is good.
yea, the fact that a wrongly installed cam bearing failed has nothing to do with it. what a moron.
tatro
ill keep my shovel bet its running long after these butthead motors are gone
Looks like someone plug welded the crank pin already. This owner is obviously a glutton for punishment
That’s supposed to be lose …..😟🏍🏍🏍
loose good, tight bad.
tatro
Rough ,throwing shit around
just wait until i put the nitro to it. oh yea, these are those late cheap ass motors. those old junk harley motors are the ones that will take all the nitro.
tatro
@@TatroMachine interesting
It's throwaway junk anyway.
@@bobberguy1 sounds like your the expert puppet boy
Absolute GARBAGE!!! Job security
are you ready for the new revolution motors. they are coming.
tatro
@@TatroMachine They're all "Throw away motors" after 1999 (Evo)
@ 10:50 you say: i do not know what the hell this part is or go's to... Haha... stay with the old Harleys Tatro and leave this new engines to the suckers.... you even said i an not supposed to work on this crap ..... correct run from it... i had a 2nd gear bearing fail at 7K on my new 2020 FXLR M8 brand new Hog... JUNK BEARING....
i didn't know what it was but i said what i think it was and i was correct. you can't fool me this easy. or maybe you did, i did look at it.
tatro
Might be time to switch to yamaha
that would be the new revolution motor. its coming soon.
tatro
Yup all throw away junk
Designed to fail
You gotta wonder if the pencil pushing prick nerds sit and figure out, we can make money on replacement parts and repairs instead of making shit better? If Tatro was saying to us, wow look how good this is and that is etc I would go out and buy one of these. Why not make it to sell more units instead of make it to fail? Same with my chevy Silverado designed to fail. I don't have Tatro's knowledge but common sense, I think I have some, I see shit and think why the fuck would you design it like that? They like filling junk yards with dead vehicles .
they build what the schools teach them to do. neither of which have any common sense or have dirty hands. if you purchase a new bike every 3 years and don't ride much you should be good.
tatro
Ha ha ha, nothing is idiot proof Tatro lmao.
yes, we can srew up anything if we try hard enough. do i get a gold star now.
tatro
Yes sir, gold stars for everyone!!!!!!
That is made like shit, cost cutting for everything no thanks.
its been that way for decades for everything. that is why most everything looks the same and last aboout the same. ugly and junk.
tatro
@@TatroMachine It's either planned obsolescence or companies bring total dicks these days. I am glad that the right to repair movement has made great strides at pressuring firms to let consumers service the things they purchased though.
