Great video Kevin. Really too bad about that low mileage motor. I'm going for my second 100,000 on my 04 carbed 88 incher. Did the crank, timken conversion, gear drive, bored to 95 at 110,000 miles. It now has 197,000 on it. Still runs great. I'm proud of that little motor.
there are certainly some very high mileage ones out there. not too long ago went into an 88TC with 140,000 on it. Really wasn't worn out either. Became a basic refresh.
While Phil Steiner got almost 800k on his 2015 Goldwing engine before just trading it in when still under warranty.
I’m so happy my ‘01 pinion shaft was within .001” runout.
Kinda glad it’s carbureted too after seeing this.
I swear, the more I watch Your Videos, the more I'm scared of buying another Harley...
I guess , everybody wants Kevin to rebuild there Twin Cam ! So do I ! Greetings from Asheville NC .
Thanks Richard. Greetings
Yup. Lol. I waited till the end of the video to read comments and this was the first. You nailed it on what I was thinking 🤣
He did mine and I couldn’t be happier. The bike rips !!!
AWSOME IMPUT THANK YOU,, TAKE CARE KEEP UP THE GOOD WORK,,,
Thanks for the video Kevin, learning more and more with every one..
thanks Kevin I’m a 67 year old man. Been riding since 10 I am drawing SS but working pArt time and wanted to go to MMI but life has other plans. Anyway I also have a 07 Ultra I bought new now has 98000 miles I really enjoy your videos your experience inspires me to get back to my
Dream of wrenching on Harleys I have been mechanicing all my life but everything but full time bikes. Anyway I look forward to your next videos. When my bike starts burning oil or whatever. I plan on taking the engine to you. God bless. Jim
God bless sir. Thank you for being here. 67 aint old ;)
MMI is a great school . Age is not an issue, and the staff is great.
If you can get yourself there just do it. I took all programs there.
Harley davidson. And the Honda 24 program are the two best ones to take . But are also the longest. MTP IS 36 weeks Harley davidson is also 36 weeks. And Honda is 24 weeks. I never had any regrets and I love my job, and I really haven't worked a day that was the same . Best time of my life was that school.
I wish I had a Mike to help me out.
I think he could pull a motor without unbolting it from the frame 💪
HAHAHA. yes sir...
I love that you take everything. apart slowly and using the star pattern, that was how I learned how to do it
Loved the video and the analysis, that is what it is all about for me !
Thank You 🙏
Thanks for the Videos and sharing your Experience with us!!!
I have a few friends that need to watch this video. Free-flow exhaust and air cleaner combined with heavy traffic on a hot day can hurt a stock twin-cam engine.
Add improper tune, etc. Basically, he had an issue, easy to fix, that went ignored or misdiagnosed. I bet the owner complained of a hot engine for a very long time
These autopsy reports are so helpful. My 07 RKC I’ve owned since new and it’s never been beat. I’ve done top end and dd7 (mild cam and FM 107) at 75-80k. Now closing in on 100k this is so helpful in deciding if I should do crank soon. Very helpful and YES Dewalt should sponsor you! Something tells me your “assistant” wore some heavy duty brass!
I am/was an auto machinist, I use to love the surprises when we got a tear down…it is like a mystery bag of legos. Or Gump’s chocolates! You can see all the evidence, and still catch a surprise in the next level of disassembly. Now that pro charger nitro bike…that sounds fun! I really enjoy your videos. Refreshing. Gotta say I really just got into working on HD. For the most part, fairly simple designs and very practical to work on, compared to say, Chevy 5.7l/350ci. Nice to be able to manage the engine so easily. V8’s can require a bit more effort. Thank you again for sharing you vast knowledge. Absolutely priceless. Let’s be real man, hit it with a good shot of nitro and it’ll clean them pistons right up. “LIKE NEW!”. She wanted and needed an oil cooler. ( I wouldn’t know if that one had a factory cooler, I’d bet not)
Thank you
Dougie
Appreciate the work you are putting in here KB. Always learning something from your videos and really appreciate your prospective on engine issues
Thank you very much Sir!
Cool video.
I like the fact that your knowledge can spot clues to the last known running condition of that engine. And, your knowledge of possible causes of the abnormalities, and problems of that engine prior to teardown.
Great video I enjoyed it and I learned some things thank you have a good day
Wow that evo springer is awesome.
Keep us the the good work uncle Kevin. 👍🤜
As i person kinda new to riding and working on bikes in general.. i might just be slow but you seem to be rushing through your work. I still learned a lot. At times i think Mike was lost . Good thing i can rewind it watch over. Difference between someone like yourself knowing and years of experience and myself only a year or so in. 😂😂. Thank you for sharing your knowledge
Hi keven iv bin waitin for a twin cam tear down exselent video thanks man
Youre welcome. I have several on the channel.
Thank you for the video Kevin, very informative.
Thank you Scott! Appreciate you sir!
Kevin, you sure can call them. Good job as usual.
Thanks Jerry!
Thank Mike for his service God Bless him
Enjoyed the teaser.
Great vid Kevin!
I have done this 3 times it's a good way to upgrade and get a newer bike. 5 years ago I picked up 2013 classic with 1800 miles for 6 grand if you can do the work your self it's a cheap way to own a new bike. But be very careful on the bike don't pay to buy a bike that cost how much as a new one
Thank you for the video good job Kevin!!
Thank you very much Rick!
Love watching your videos.
Thanks for sharing such great information 👍
thanks for being here sir.
Excellent video again! Thanks I'm having my 01cvo roadglide rebuilt having s&s crank installed already have screamin eagle hydraulic cam chest should I put external oil cooler? Or any other suggestions? Thanks
Thanks for the education Kev, it's very good of you to share your knowledge with us, great show, I'm a shovel guy and have been over 40 years but I have had a couple of evos as well, what you teach us is relevant for a lot of engines in general and you can never learn too much.
Thank you so much Gary!
I really enjoy your video's I have owned 4 panhead's a shovel head 3 evo's 3 twin cams my favorite engine is the Evo I still ride a carburetored Evo
Super informative! Thx!
Glad you enjoyed it! Thanks!
Kevin, having a mechanical background I appreciate all yr vids, 1 of my bikes, the 01 ultra started sumping a bit at 101,500 miles, did the screaming eagle cam plate and oil pump, now at 108,900, running good again, oil pump was worn, yr tips wS the road map to diagnose the issues, thanks, best regards
Great video Thanks 👍
One thing I do notice about all of your videos is that you follow procedures on tear downs and rebuilds. Using the tools that are necessary for the job. I myself do not like to take shortcuts.
Keep up the good work.
I am a MMI graduate, and instructors pound it into our heads not to skip steps. I have watched other videos, I won't mention names but they know who they are.
One question I have is have you ever used a megger meter for checking the stator for an open in the windings?
Master at work .
KB you are the best I'm taking a motorcycle repair course at the local community college and I showed the class and instructors your videos they can't believe how detailed your content is. Thanks for the knowledge I love twin cams but you have made me come to appreciate all harley davidson engine's. Thanks for letting us see what you see God bless you keep up the awesome content
Thanks for another great teardown video. I know it's not your business focus, but it would be so interesting to watch you tear down a 4 cyl. Honda or something to get your opinion on it.
If you look back at the GMC series...I do a complete tear down of a GMC 302 inline 6 from the early 50s. Still a project I have in the works.
My uncle rest in peace had one of the original Knuckleheads before the war. He used to say for $500 you would get the best motorcycle in the world or the crappiest car in the world. It was a super light 1,000 that came with a certificate stating that it went to 110 miles an hour free World War II that was pretty good. Long after the bike was down the road he had the certificate in a frame in the hallway. A 61 was a lot smoother than a 74 the 74 is just for the police bikes. After the war Harley just continued the 61. That bike really looks cool. Nothing runs as good as an EVO. So I remember in a road test about in an old Panhead it was said that the bike ran as cool as an Iceman's shoulder. Those old Harleys ran great and didn't cook yourself to death riding one of them either. And they were nice and simple bikes like my British stuff. No blinkers no turn signals no electric starter headlight tail light brake light horn that's it with a Magneto for ignition.
Mr. Baxter I would like to apologize to you even though you didn't know anything about this. When I first started running across your videos I didn't much care for you but I have to say I started making myself watch your videos and ended up subscribing to your channel. I'm mute (can't speak) with other issues. Anyway I love motorcycles own 3 Harleys and your videos has been the best detailed videos I've came across. So with that said I apologize for judging you before I knew you (through videos) keep making videos and God bless you sir.
Well thank you Brian. I appreciate your candor and for posting this. Much respect sir. Glad to have you here.
Wtf?😂😂😂😂
I just stumbled across these videos and I gotta ask, what’s not to like about this guy? Knowledgeable mechanic who doesn’t talk down to his audience. Kinda the perfect person to make this type of video 🤷🏻
I believe he is also a mechanical design engineer???
Yes I know this video is "old" but it seems like things were done without that motor being tuned afterwords. A lean bike caused by an aftermarket exhaust and intake, plus a lack of regular maintenance, and low octane fuel could have accelerated that issue. Congrats on 60k subscribers! There are 3 or 4 types of people that buy a Harley. The ones that can, the ones that think they should, the ones that someone makes them think they want one, and the ones that love the history, the sound, and the character from the early 1900s to (almost) the present. (Not a big fan of the sound or the price of the M8 bikes!) I stumbled across your videos looking into a bagger after my wife suddenly became slightly interested in possibly riding with me. Looking at a 2012 Road Glide Ultra with the 103 as an upgrade to my 2014 Iron 883. I love the REAL technical info, visual references, and the videos with manufacturers explaining their products! I might be better off finding a salvage bike and doing a better part of the work considering what the engine alone might cost me! I would GLADLY trailer a bike down to you, from Ohio, for a rebuild after watching a handful of videos! Attention to detail and thousandths of an inch are right where I like to be!
Great radio station y'all listening to also
Love your videos!! Let’s see a build instead of a tear down thank you!
Thank you
A close up view of your engine while you dismantle would be awesome!
Noted!
Got some friends who run Cam,2 in their stock bike motors.. Never felt that was a good idea myself.
Would you be able to use the crank and just replace jugs and pistons?i have a 13 103 with low compression 50k no past history-and im looking @ rebuilding it in the next few weeks whats the best course of action?
Could the oil on the compression release be from bike being laid down, and sitting on it’s side for a while??
Kevin, please can you show me how to locate the rubber cap on the vacuum port on the throttle body? Hot running TC here. Thank you
Man that's a nice bike I would have put a kicker on it icing on the cake.
Thank-you for sharing
As a Harley Davidson Tech I really love watching this guy wrench, all the respect to this guy!
Hello Kevin. I just found you, and will follow along from now on. If i may ask a question? Should we run some sort of cleaner through our fuel on occasion to clean carbon? Something like marvels?
Do you do compression test and leakdown before teardown curious on psi
these tear downs are great look forward to the rest of them
Engine may have been overheated during a "butt the front tire against a wall burnout session". I've seen guys turn shovelhead cast iron cylinders glowing red hot at night doing it. It cooked the rings doing it too.
Mr. Baxter, thank you so much for bringing us your videos. Always informative and helpful.
You mentioned an uncapped intake port and I think you are right on the money there. Lord knows I've seen them missing. A clueless owner won't know and a mechanic might not notice. In this line of business, attention to detail is paramount. And you have it. And you share it for the community to benefit. Thank you and please keep on providing us with educational videos, we really appreciate them.
Thanks
Would water injection added to that vacuum port have cleaned the top end if they had diagnosed the problem in a timely manner?
Speaking on the baked gunk on the piston crowns what are your thoughts on going to an external breather to prevent carbon build up?
What about an oil mist problem due to the internal breather system. DK custom cycles sells an external system. The internal system throws oil back onto the pistons due to an EPA regulation. Thoughts?
Clip that mic on your hat. Loving the content.
What do you pay for the motor?
Dude your a beast!!!
Now that's a good looking Evo ;-) ✌️👍😊🏍️👌👌👌👌
Would a bad crank position sensor cause detonation when its up to temp and i restart it,then at times i get detonation..its like the Piston get thrown down the wtong way when starting back up...thanks hope explained that the right way lol
You mention engine heat. What would be good temps for a M8 131. Right now I’m seeing cruising temps of 320 and 350 sitting in traffic. Temp reading was engine temps on the powervision.
Depends on what temp were talking about, head, engine, or oil
@@KevinBaxter head temp. I think engine got up to 330.
Great video.. question.. if the bike was sitting for years.. would that much oil still be sitting up there? Could it have been laying on its side?
Possible sure...but oil will stain a cylinder if sitting. Oil was getting past the rings. Carbon was wet...not dry. So its oil carbon not fuel.
O.J.T. learn as you go
Those Pistons would be great for a Random Giveaway,,,,lol,,,,Heat isn't our friend
Thats a great idea....thank you!
On the stator how can you tell the magnets are going bad on the twin cams?
Wonder if the carbon buildup problem was from using the mid to low grade octane fuel.
I have a twin cam in my Deuce, but it's not too hard to understand that there are limitations when the engine technology is behind that of many lawn mowers.
I remember in the old days a Harley Rider would make sure that his bike was taken care of before the ambulance had left the scene of the accident.
👍👍👍👍👍 🌞.
👱 How do u fix run out on evo 88 late model 99 to 01?
Is octane booster bad? I use it because it comes in my fuel stabilizer and as an otr truck driver I am only able to ride my bike about every 5-6 weeks and my bike sits a lot.
So the takeaway here harleys dont do well in hot climates or in traffic. I just picked up a 2017 low rider s its pinging under heavy throttle. It runs hotter than my 88 no idea what it should be running temp wise.
Kevin im trying to get a bead on that white bike in your background. What's that front end on that bike
I would believe the gold color signifies, over 600 degrees isn't that close temp, oil boiling maybe ??
Would Dec of 12 be date of manufacture possibly derived from serial (vin) numbers? Then the salvage facility would know what they are selling at a glance...
I agree with that. Couldnt put 30k on a bike in that short 9f time.
Those pistons and heads were nothing compared to my twin cam when the stock Chinese valve seals let loose at 10,571 miles. 1/8” thick burnt oil.
wow!
I'm betting the guy was a burn out king to scorch those cylinders like that
hard to say really....still some mystery left we shall never know.
Mike looks like the kind of fella you say “yes sir” and “no sir” to. Or he’d wrap you in a knot lol.
There is always talk of heat and excessive damage it can cause. How accurate do you feel the Harley dipstick temp gauges are. I recently got one and never see oil temps over 210. Is this acceptable in your opinion?
cyl head temp is the key one. oil temp is a good guide for average temp and 210 isnt bad at all.
I have never heard of a twin cam with 10 - 15,000 mi on it that doesn't have that much carbon build up on top of the pistons.
Carbon build up is due to use of high octane gas , check any Harley using the highest pump grade octane and you will always have tail pipe carbon build up,unburnt fuel. I always use mid grade fuel here in Canada, never have any sign of soot in exhaust pipes.and engine runs as normal. 31:05
I have two pans and a 09 ultra classic , and a 06 soft tail. Note the best way to tell if your engine is running right is to pull and read the spark plugs , they tell all of the story.
Great Video Kevin. I've got a 98 FLSTC and I'm interested in what springer front end Mike used on his bike. Is the seat a custom or can that be bought as well? I assume he swapped both fenders out as well. Be nice to see a list of parts it took to make it look that way...
those were all reproduction parts specifically for a correct Knuckle. Seat can be bought as well. If you are interested, you can reach out to us by email and we can get a quote for you on all the parts.
Great chanel..
The faux Knucklehead at 0:25 is out-of-sight cool.
Over and over... sounds like a GREAT REASON to have "LOVE JUGS" I got them for my M8 right away.... and LOVE EM... @AmsoilAdam
judging from the look of the internals could it be said the owner took good care of the engine as far as oil changes went / no apparent damage to cams, crank , rods, bearings , lifters etc ? just wondering, if you think your doing everything right but still unknown damage can and did happen. Great channel btw
i agree with you. it was wearing quite well really. thank you!
Them colors are great togerher
Kevin, is it a given that whenever someone buys a used Harley engine from a junk yard, dismantler, or private party, that it would necessarily require a complete tear down? Would it not be advisable to install a used motor without having knowledge of what issues lie inside? Thx.
So, are you saying that octane booster is bad, or was just an attempted cure for a overheated motor?
Cheers.👍
Thank you! Cheers!
We're can I find a good salvage yard to buy stuff from .
If I put octane booster in tank for no reason other than fun ...will it have negative effect on motor?
octane booster really wont add any fun. by boosting octane you retard combustion effectively sort of like retarding ignition timing. if you drastically increase octane, then tune the bike for it or increase compression ratio, that's when you can see some gains.
WHY would my 88 built to 95 start filling the transmission with the crank case oil?? Anyone?
I am glad to have lived in the times when a Knuclhead could be bought with a machinists two week wages
Wish i could say that sir ;)
you say this is a 2013 twin cam, but it's still got the mechanical cam chain tensioners? I thought they started using hydraulic in 2007?
that is a hydro chain tensioner. with a mechanical you would have seen a large spring.
Hey man. A small pan under the mill to catch the oil would make for a lot less moppin up.
