Interesting to me that lifters can be mixed n matched with no damage to the cam nor the push rods over time, no more than normal, something I never thought about, but Im learning much as I can every day, even though my bike is new, I love to learn as much about my motor as possible its very interesting to me, Thanks Kevin !
Good to see you again. I did a cam in my bike a while back wish these were out when I did it I may have to go back in soon and check them anyway. I am rocking the same skunk works hoody today!!!
i agree why is it you always have to fix something on a Harley, i bought a victory because of this reason,only had to replace tires,oil and brakes. never any motor work. 70,000 miles and going strong.
Dont see many of the PP engines around. Have one in the shop but it wasn't major engine work. The last big engine I did on a TS was about 2 years ago. It's a runner for sure. As busy as we stay on the HD side, it's hard for me justify swapping tooling, setups, etc to do the occasional TS job. One of the most knowledgeable guys with the PP is Frank at Blackhawk Motorworks in Florida. He's a great friend....know's those bikes inside and out.
Sir, what is the purpose for the cavity inside each bore? It is an oil conduit? I recently installed my new lifters with the oil hole facing the cavity, in the event that oil would come out of the cavity and flow into the oil hole.
Did they seem to fix this porosity problem in later M8s? This is actually the first I've heard of it. I have a '21 114 I'm about to do a cam swap in, and now I'm concerned about my lifter bores.
I HAVE A 2017 ROAD GLIDE S WITH 91K FAIRLY EASY MILES ON IT. I JUST NOTICED IT IS DAMP WITH OIL AROUND THE FRONT CHROME LIFTER COVER. COULD SOMETHING NEED TIGHTNINGZ?
To maintain same thermal properties across all 4...and only repair 1 because that's the only one that required it. Be as little intrusive as possible so to speak. At 200 deg, the case bore expands approx .001. The tappet will grow about .0005 providing additional clearance. Keeping the native material assures it remains consistent.
@Kevin Baxter If you start out at .001 clearance, and at 200° you expand .001, and the tapped grows to .0005, that would give you .0015 clearance. Is thar acceptable? Or maybe my math is wrong!
Good info, but why not hone the front exhaust to .001 oversize and use 4 matching lifters. If the engine ever has to come apart, this way the person doing the work doesn't have to keep track of the 1 standard lifter. Or worst case scenario, someone working on it without any knowledge of the 3 oversize and 1 standard and they mix them up.
Some of that has to do with tolerances and be as least intrusive as possible...removing only what's necessary to get the bore correct. Another asked...why not sleeve them all while you are in there? Similar answer...because they didn't require it. Besides, if it did ever come apart, i would hope, even if all were standard size, or the same size, that the tappet would be returned to the same hole is was removed from.
@@KevinBaxter I get the "be the least intrusive you can be" thought process, but the reality is, you're already there, make them all match. We don't bore only 1 cylinder because the other one is fine. When lifter bores have bushings installed, every single one gets a bushing. Same for valve guides. If this was a situation where money was an issue, that's one thing, but that is obviously not the case with this build. P.S.: I find your videos very informative and do enjoy them! I have little experience with V-Twins but have built a slew of V8s over the years so my mindset is coming from that angle. It's just a fancy air pump right? 🤣🤣🤣
Kevin Love your videos. Where can I find this tool. I don't have an M8 yet but I see one in my future. I checked your site but could not find it. Thanks Little O
All this information on what a terrible moto the M8 is. Guess I'll just ride hell outta my 2020 slim past the warranty then revisit the vids and do a Biden build back better thing. Let's go Brandon!
Hi Kevin , I think if that was my motor , i would have had you sleeve all bores and back to stock size lifters for peace of mind , great video
Man this is a game changer not only built to perfection but this gives proper fit better oil pressure and less probs down the road
Im glad I bought my bike before seeing your videos...lol
Great explanation, as always. I'd never considered that a bore could be so whack as to require a sleeve.

Just FYI OCGlide used to be Bob Stubbs I changed my handle. My granddaughter told me it’s not cool to use your real name so I had to fix it. 🙂
Kevin, thanks for the video and good to see you in the New Year.
Thanks for sharing! Important information in this video that anyone doing their own cam and replacing lifters should look for!
If Harley-Davidson, Inc. manufactures engines with such obvious faults, can't the company be held responsible for the damages?
i agree why is it you always have to fix something on a Harley, i bought a victory because of this reason,only had to replace tires,oil and brakes. never any motor work. 70,000 miles and going strong.
Very good video Kevin!!
I used the fit kit on my 2012 Ultra Classic. I figured a couple bores were oversized but what I found was all 4 needed .0015 oversized tappets.
Great work Kev
Gotta love Go - No Go gauges, best time saver for 1 off and production machining
Thanks for sharing Kevin
Love from Mississippi USA 🇺🇸
Thank you Kevin for sharing your Wealth of knowledge it's Greatly Appreciated.
Thank You
Look forward to the new vids ... Cheers.
Kevin, could you do a comparison build of a M8, Thunderstroke and a PowerPlus.

Was that motor sumping when it came in? Why do the M8's have this issue? is the castings not what they used to be? All the above?
All the above sir.
Great video!
Sir, what is the purpose for the cavity inside each bore? It is an oil conduit? I recently installed my new lifters with the oil hole facing the cavity, in the event that oil would come out of the cavity and flow into the oil hole.
Thank you for the part information, eventually I hope to schedule some m8 upgrades.take care..
No problem 👍 Thank you sir!

Good stuff!
Thanks!
Can I remove the lifters from the bottom and install new ones from the bottom
Man, I need to stop watching your videos. Makes me nervous about buying a new bike! Haha. Thanks for the content!
I wish I did exactly that…. Would’ve saved me 30,000 plus and a boat load of aggravation.
Love the knowledge.
Hey Kevin, this is good information where is the link to your fit kit? Mike from Maryland
www.baxtersgarage.com/product/twincamm8tappets/106?cp=true&sa=false&sbp=false&q=false&category_id=14
What company's do the repairs? My lifter seized to my case and needs repair
So GLAD I have an Evo
Wish I never sold mine I’m buying another soon
Are these still available? I don't see them in the store.
I HAVE A 2017 ROAD GLIDE S WITH 91K FAIRLY EASY MILES ON IT. I JUST NOTICED IT IS DAMP WITH OIL AROUND THE FRONT CHROME LIFTER COVER. COULD SOMETHING NEED TIGHTNINGZ?
So what pushrods are you running with these tappets?
Feuling on this build.
I can’t find those lifter bore tools on your website or the Jim’s website , where can I find those?
I can't find tools either
How come we can’t find this tool on the website?
Where can I get this kit
Where can I buy these
Another prime example of those damn “ loose tolerances” coming around to bite us in the ass.
Any reason you don't use bronze sleeves in the lifter bores?

@Kevin Baxter
Are you sleeving with aluminum sleeves?
Thanks.....
Great work.
That bike was a 2017. Have you seen the same issues on the 2020 model ?
Do you still offer the lifter tappet fit kit? Searched ariund on your website but did not locate them.
Can't find tools either
Does these mechanical issues effect the 2021 late models bikes too?

I’ll keep my twin cam 117”
Why not hone the one out so there all the same

Hate to say it,but your videos show just how sloppy Harley builds their engines. Doesn't look good for their quality control.
