You know, you have to be the most knowledgeable engine builder around, I am super impressed by the way you spread this information to everyone. I enjoy your videos.

[@tcb8295]

Wow, that's crazy how much run out that crank has... thanks for the video Kevin.

[@KevinBaxter]

Youre welcome. Thank you.

[@CarlosGarcia-ls4hn]

Actually no. That runout is still acceptable in a chain drive crankshaft. How do I know? My bike is running with 0.005 runout.

[@jerrylong381]

@@CarlosGarcia-ls4hn Big difference between .005" and .036"

[@paulfiore7083]

I've learned more here than any class in college. Thank you for helping me understand my beautiful '01 FXDX TC 88 better. SE cam chest/oil pump, S&S .510 cams, S&S cam gear drive. Pinion run out was under .002

[@KevinBaxter]

excellent! thank you for the kind words!

[@GHOSTINPLAINSIGHT]

Hey Kevin. Ghost here. That is a hot mess. Glad to see you and your shop are busy with work. It’s a blessing in today’s times. Awaiting the next tear down! Love the detail and the analysis of failure. Keep up the good works!

[@kerrylewis2581]

That poor engine definitely needed saving. Luckily Doctor Baxter has come to the rescue.

[@michaelpascual2731]

I have a 95 FLSTC and at 35000 miles the front piston came apart and destroyed the motor so I bought the parts and built a 127cid monster and stuck it in and man I have been so happy with it dynos at 150 hp and 155 tq and if you are relaxed when you twist the throttle it will leave without you I love it. The bike has 55000 miles on it now and it's still a screamer , since installing a Vance and Hines 2into1 pro pipe on it seems to run better also S&S super G with some mods done on it makes me want to ride it all the time 😊😊😊😊😊

[@-MrRichBiker1967]

nice, sounds like a monster,mo!!

[@georgekelly8900]

Spent 12 years at a HD dealer now working for a small shop here in Ga. I can really appreciate your attention to detail and enjoy watching your vids!

[@karmsenrab8587]

My '06 had 21000 when I put a billet camplate & hyd. tensioners , plus a high vol. oil pump in it . Got .004 pin. runout. I added a dip stick that has a thermometerr on top to keep an eye on the oil temp, so far 220 is the hottest its got. As far as wear, the motor parts looked very good, when it is time to rebuild(if I'm still breathing), it's going to be from the bottom up complete.

[@richardboggs260]

Thank you Kevin,missed you live again,but you are just as good on the reruns!!

[@rsbharley4766]

Excellent video Kevin, thanks for taking the time to share. Cheers

[@johnyknox1126]

I watch a lot of your videos.I’m not an engine builder or mechanic, but I do work on bikes and have put a couple engines together. With the help of your educational videos of course. I appreciate that you take the time to explain everything in detail so that everyone can not only work on these things but understand them as well. I will continue to watch and support your videos. Thank you, you are very knowledgeable, and a very good teacher.

[@-MrRichBiker1967]

then yes, my friend you ARE a builder!!

[@davekennedy4002]

Another great one sir, picked my 13 RGU up yesterday, break in miles started, mentioned you Kevin to my builder, he knows you and respects your abilities, break in almost a carbon copy of yours. Loving what I’ve seen in the first few miles. Thanks for great tear down video. 👍🏻🇺🇸

[@KevinBaxter]

Excellent. Thanks!

[@rickswindell1964]

That thing had to be vibrating like crazy!!

[@stevebumstead9840]

Super interesting, can't wait for the other tear downs. Thanks Kevin!

[@danielbates4137]

Man I'm looking forward for this tear down series. Very informative and interesting 👍 great job.

[@celtics9348]

Thanks for the detailed teardown, looking a a 07 110cvo this changed my mind not worth the risk to me. Far to much money for the bike to have these potential problems. What a excellent video thanks.

[@jmac6242]

Great video!

[@mikedanaher3413]

Wow over 30k runout!!!! Wonder what it started with new. I’m guessing it was probably 15 and just got progressively worse. That engine is in good hands now. I’m confident that the owner is going to fall in love all over again with his bike. Great stuff as always Kevin.

[@ridinout6308]

Wow! It's amazing the pump an cam plate held up as long as it did. Thanks Kevin, great video as always. Really looking forward to the M8 tear downs.

[@CarlosGarcia-ls4hn]

If you are referring to the runout, actually, 0.005 is still an acceptable runout if it is a chain driven pinyon shaft, however, it would not pass muster for a gear drive shaft. My bike, a 2000 Springer has a runout of 0.005. Because of money issues, I decided it was not in the cards to replace the crank shaft. I don't like it, but it is what it is....

[@kct9967]

I Remember when the 117 kits didn't come with the bearing conversion, because they said we didn't need it, luckily Jim's had them, secondly I have never got a set of SE flywheels that didn't need some truing.

[@georgeveneziano2754]

I agree I've learned more watching you then any other around you are awesome love the videos keep up the good work

[@hankhamern5456]

Always a pleasure to watch your videos, I can't wait for the m8 teardown. Thanks.

[@KevinBaxter]

Thank you very much Hank for your support sir! Youre welcome.

[@keithpetrocik6947]

Nobody ever talks about the damn oil cooler thermostat. I had my thermostat fail and it cooked my 110. Opened the rocker box and it smelled like rear end gear oil.

[@rubesanchez1942]

WOW!!!! This is Modesto, but my KZbin is under my alias Rube Sanchez. Just became a member. Thanks Kevin, you are a wealth of knowledge!!! You are AWESOME brother!!!

[@steveflor9942]

Fasinating stuff. Thanks, Kevin

[@torbenkristensen1079]

Just love these tear downs.

[@gregoryranlett7868]

Thank you, Kevin!

[@JonV-r7q]

That cylinder looks like a mirror. WOW 😳

[@jonz5978]

Thank you for your time. Great Channel!

[@davidleduc2779]

This is the only youtube video i real;y watch. Absolutely awesome!

[@windtherapy99]

I’m not sure if it has been covered previously, but what should a proper warmup procedure consist of when we get a big bore kit done? Just let the bike idle for a minute or two and then be easy on the throttle for the first 5-10 minutes? Any other important practices?

[@texas1040]

I am just about to buy a 2008 HD RK CVO with the 110. The bike is super clean however has 49k miles. Some people say stay away from this bike due to issues with the 110 and some say run with it. I am on the fance with this.

[@mattovictimcycles1334]

Wow.....getting ready to put Fueling cam kit into my 07 96 inch Ultra,Classic....but watching these teardowns has me a liittle worried on what I am gonna find... 40 k on it.....Well....Columbus took a Chance...... Great Information..Thanks

[@superplumber5]

09 Dyna Gonna be checking my runout this weekend...got a set of woods cams

[@texas1040]

Good day, I am looking at buying a 2008 HD Road King Screaming Eagle CVO 110 with 49k miles. The bike is showroom clean. I have been reading a lot of feedback that the 110 eng had a ton of issues. I know it depends on how well-maintained the bike was. With 49k Miles should I pass on this bike?

[@bryanpride6945]

Thanks Kevin, really enjoy your videos!

[@mitchelldarnell5334]

I'm late again, Lodge tonight. Scares the crap out of me. Now I'm scared for my 08/ 96ci. Already had an oil pump problem. early in its life? 11 CVO/110 only has 5000 miles. Dang its only the first tear down, and I'm panicking🥴🤠

[@jeffhawkins711]

Dude, you do a tremendous job of desribingand trouble shooting problems with H.D.s I have finally aquired my first twin cam. Never had an Evo always had shovels couldn't afford the late model bikes I'm 68yrs old now .I managed to get an un molested 2006 fat boy back in July seems to run real strong . Just has the stage 1 thing done vance & hines pipes and breather.if any goes south , you'll be the man to deal with it Dude I got it from gave me 3 cases of that synthetic hd oil and 12 oil filters said that's all thats ever been put in it .thanks for your time.

[@JonV-r7q]

Great video tons of information. Thanks Kevin

[@charlesd6459]

Great content as usual

[@richedmundson8964]

Wow,talk about being on your last leg. That engine was on borrowed time. But don't fear,the dr is in!

[@Marcus_from_OZ]

Another great video mate, side question, at what temp would the ecm start start pulling timing out of these engines and is it different on an M8?

[@rickh.959]

Thanks for sharing. always good to learn these things, just in case.

[@hdfxst1521]

How many miles did this 2007 110 have? I have an 07 TC96 in a softail with 31,000 miles on the clock and after watching this and other tear downs, man I’d be lying if I said I wasn’t nervous about my bike.

[@carlbruhn1772]

54,000

[@ccollins9981]

I'm going to go ahead and consider my 08' 96-in with .005 run out like new now!

[@CarlosGarcia-ls4hn]

My bike also has 0.005 runout, and I thought that was bad, I feel good now!!

[@mikemastropietro9482]

Excellent video thanks Kevin!!!!!!

[@Chase_N]

How do you know if your Twin Cam is running 'hot'? 88s, 96s, 103s, 110s what do they usually run on the temp sensor? 230F? 240F? 250F? 260F? I can't seem to find anyone including Harley that'll give me a straight answer.

[@petevicente9236]

Fantastic video.. you are one hell of a wrench

[@tobpitbull]

This heat can be customer related as well … I ride daily, and it is common for me to see traffic backed up a while and guys setting in traffic with it being 80-90 degrees on there Harley-Davidson. My oil never gets above 225 on a real hot day and typically runs at 205-210. Harleys setting in traffic lines in hot weather is a recipe for short lived motors and trouble.

[@fireball1322]

Yep. Like Myrtle Beach Bike Rally traffic. it was rough on the Shovelheads.

[@garyblackstone6379]

I like to see an 01 twin cam tore apart and see what you got in there

[@patrickstevens5457]

Wow, a ton of runout

[@GilstrapGarage]

Kevin inspires me to be a better mechanic 👊🏻✊🏻 your knowledge and experience is in another level. Thanks for the videos

[@Greenjeans2020]

I have never seen that much runout on a crank! With it's multiple issues it seems to me that the compression release was the main culprit. Just a guess. Another great video!!

[@gasmann6746]

Nice work Kevin that crank was way out ..👍🏻🇦🇺

[@richardprado6345]

Man Kevin, you sure do move fast. I like the show a lot of information. I appreciate you helping out like that love watching the tear downs. just a question what would be a good running temperature? I have a road king classic with 120 motor on it and I have a fan cooling oil would be a good normal running temp

[@sithyarael6807]

Watching the tear downs reminds me of the ones I did I did on my 1.8 scales nintro's cars.

[@BWTT]

With the decompression valve leaking well that contribute to motor overheat? And do the 107 Big bore twin cam have heat issues

[@craigbuness5554]

Thanks Kevin, excellent video!

[@thomaskirkpatrick4031]

The fact that an engine in that bad of shape, stayed together for as long as it did, is a testimony to the big twin design. I still have no use for any of the newer engines.

[@KevinBaxter]

He caught it pretty quick...i am often amazed at how bad one of these engines can be and still run.

[@jeffreycarroll5920]

Lookin at all of those problems to fix seems like it would be cheaper To get an S&S crate motor and put in rather than rebuild it

[@windsurfed1]

Great video Kevin. Looking forward to the other engine breakdowns.

[@welderup6669]

GR8 VIDEO THANKZZZ FOR SHARING!!!!

[@fililoboesparza5784]

Great video. But man makes me think about my 110!! I have a 2016 FLSS did H-D fix the problem or did it continue on mine?

[@Bass.Player]

I bought my last Harley in 2000 for a reason. As much as I like them they have too many issues for me. I think the EVO Was probably the best...My favorite was the Shovelhead...

[@jeffhudson1744]

Great videos!!!

[@outlaw6849]

Hello Kevin, great video like all of them, got a question? You mentioned some of the SE 110 heads and cylinders have issues I know this also is 2007, I have a 2016 SGS 103 with a Big Bore Kits 110 can they have the same issues as this 2007?

[@mmmark8737]

I'm curious how many miles this engine has on it. That all is pretty horrifying. It can't cost all that much to forge a V-twin crank, right? These teardowns are absolutely brilliant.

[@carlbruhn1772]

54,000

[@markfrank2454]

Great stuff! One thing I did hear you say a couple of times and no disrespect to Michael black oil with the things wrong with this motor could it of been a bad tune not a cylinder pressure check? I keep on top of my oil and how things sound I bet this one spark knocked with the best gas, but is it safe to say if your oil is getting black way too soon you may have things going very bad in side a motor? Just a question?

[@dumas8542]

I have a 2015 CVO Street Glide with about 25000 on it. Are the known issues still about the same or have they gotten better since the 2007 110?

[@nickglorioso6266]

Wow, very interesting, he was riding a time bomb

[@mohawkmikemotorcycles9077]

Appreciate you

[@spyda3856]

I thought my '08 110 SE Dyna was bad @ .007" pinion run out after it'd been running way too rich and also the front exhaust broke at the header after being knocked off in an accident, causing it to sieze on both cylinders, running way too hot, only had 40K on it. Couldn't afford £6K full rebuild, (i live in UK) so only re- rung it, it really needed new cylinders/liners as .010" re-bore not enough, you could throw pistons in!! Ended up having to put new SE255's in, new lifters, (due to bad lifter previously/seperate occasion) but oil pump and cam plate were still within spec luckily. (fitted Fueling bypass valve/spring) Also got a Thundermax now, crankcase external breathers and finally got a S44 K&P Eng' Re-useable Billet oil filter ( larger than stock) and using 20W50 Semi Synthetic in motor, (help with blowby) i swear blind she's running better and significantly cooler!! Done about 4k miles now since top-end "Bodge" i'm amazed, must have done something right eh, but it ain't gonna do the usual expected 100,000, no way!! Love to stick an S&S in it!! I wish!! Very good channel and look forwards to seeing the 117" build!

[@-MrRichBiker1967]

Hey Kevin...another Awesome one my good man! ty got a quest, big guy. I was adjusting the primary chain( 5th gear ,plugs out) i was having a real hard time turning the wheel over by hand!! i have a 2005 anniv fatboy, 95"-1550, new ss crank,fueling camplate and hp oil pump. with Andrews 37 G gear drive cams, stock heads, NO COMP RELEASES, and new fueling lifters, james'- new piston rings and all new gaskets!! i have only 3 ,000 miles since all the work! It runs like a R----d ape, beat on it, every chance, loves it, asks for more! when i turn the wheel by hand, it feels like a tight spot!, then it goes! in your video....got me thinking,cuz, please help...ty in advance.

[@moonrainbow1455]

Hey Kevin this is an old video but very informative.I just brought my 03 deuce in and found bearing exploded from my cam now unfortunately they tell me they must tear it apart to look for more damage .do you think all that is necessary getting expensive

[@mynamedoesntmatter9013]

What exactly is a compression release? Is it some kinda overpressure relief valve?

[@kennethpensyl7791]

The Harley is an art Form all to itself. All of it's parts need to be made to perfection. And it needs to be assembled by experts. That crankshaft was probably defective when the engine was assembled. And that loose pressure release should never have gotten out of the factory.

[@frankbutaric3565]

Where is the quality control on this art form? One should not need an expert for assembling the engine at the factory. Just follow the proper training for the job.

[@TubeBrowser2]

Really cool video of a great save. Can someone tell me why the MoCo does not weld their cranks? Seems a simple and inexpensive robot thing to do. Surely there must be some tangible reason not to.

[@KevinBaxter]

Sure...the cranks are not balanced from the factory. Their assembly and machining processes are built around a certain range of operation and knowing its not balanced. If they welded them, they would then need to go back again, true, and balance. Too much expense i guess for a high production environment.

[@richporak]

That crank runout 😂 WOW !

[@bynumpi]

I have 2012 CVO 110 and have heard of failed lifter issues on these motors that others have attributed to excessive valve spring pressure. Did this bike have original valve springs? I noticed that you did not think the lifters showed excessive wear. Thanks

[@danfecke]

I have a 2012 also. Great question.

[@rickt6124]

How many miles on that 110

[@bryanday1326]

I have a 2014 street glide special 103 with 78k miles, What should I check first ? The price of a new 124 S&S crate motor.

[@K9RickRet]

Always an education! 👍

[@bogiewheelman71]

Makes you think twice about buying online now.

[@bobo12055]

Did it come from the factory with that much run out? Did the crank scissor? i have a 2007 low rider. Do I have to worry about these problems? It has a little over 6000 mile on it. I haven't had any trouble yet. Thanks.

[@seanflynn5405]

Your videos are awesome full of knowledge I appreciate you taking the time doing these videos I myself I have an 04 twin cam electric glide look into get more speed I don't know if I should do a 95 in big bore kit on it or throw some cans in it just saying

[@lifebehindbars6283]

How many miles were on this engine?

[@dougrobison1209]

Interested to know a couple things. 1-What parts would get reused if there wasn't so much damage? Is anything besides the cases getting reused on this build?

[@sowelovetohunt111]

How would you like to do a 110 2007 CVO with 114,000 miles?

[@jeffalessi]

How many miles where on the motor? Have a most awesome evening!

[@carlbruhn1772]

54,000

[@petesteinis2991]

He said the crank would need replacing. Why not go with a stroker crank ?

[@warbar95]

What can I say. Another GREAT video Sir. GOD BLESS

[@davehicks2385]

Perhaps it's time to start using the VROD motor.

[@darrell3368]

Loving the shows and learning a lot thanks for sharing and God’s blessings for and all your family

[@chalibanec1]

Can be loose Compression release avoided? What's signs? Thnx

[@KevinBaxter]

I would say this isnt very common. Clues would be lean condition and or inconsistent running condition.

[@Hooijnbvn]

To hear people talk you would think the M8 is the only HD engine that has ever had an issue.

[@tomposton5732]

I missed if you mentioned mileage on this unit ?

[@carlbruhn1772]

[@F150-s2h]

Hello from Germany. Three weeks ago i bought a 2007 Road King CVO with 7300 mi at my local harley dealership . The Bike is still in the shop and gets some modifications as a 18" Ape, Seat and a Set of pipes. I read in some german forums that the 110 CVOs had some issues with head gaskets and sometimes with the lifters. After watching this informative video I am a little bit worried, if it was the right decission bying this bike. The only thing that makes me feel a little bit relaxed is, that I bought it with two years warranty. Can anybody tell me, if all engines from 2007 have the in the video mentioned issues?

[@kurtruppenthal9506]

I've always heard nothing but problems on those 110's. That thing was toast.

[@joekubesch8558]

How many miles were on that motor?

[@rootrriddr6181]

Your experience and expertise make it look easy Kevin, how many miles did Mike have on this engine,
