Kevin, I understand that the newer bikes with Twin Cams and the M-8 are the latest and greatest, and right now are you bread and butter, but what about us old timers? Are you ever going to make some videos on older engines?

This is one of the things Erik Buell did to his Buell XL motors that is often overlooked.

Extra points for nailing that "just rolled outta bed look" 😆🤠😄✌

Hey there buddy I'll see you Tuesday morning

Never had a flywheel assembly explained in more detail like that. Flywheel assembly is very interesting.

I should have waited until the end of this video, before I asked about older engines. Looking forward to the Shovelhead build, still have a soft spot for the older iron.

Well I won't be reducing the weight, but I'll sure be getting the crank welded. 👍🤘 Great information kev.

I’d love to see an Evo build from bottom to top!

You are an excellent teacher. I'm 62 years old, but I didn't understand the subject until now. Your approach is perfect.

Kevin, unfortunately I missed the premiere, but got to watch it later. Another informative video. Thanks for the info.

more correct understanding of the basic v twin. outstanding Kevin, tks.

So great to hear proper terminology and common sense spoken and the mechanical reasons why every action has a reaction within assemblies and systems as a whole.

Worked for Harley Davidson for 19 years. Love your channel.

Excellent video Kevin, this is exactly the kind of information I'm looking for. I love it when you get into the physics of engine design and application. Can't wait for the next one.

Thanks again for your wisdom , you are indeed a wonderful teacher and I can't wait to have you build my twin cam .

Great info, I have been searching for details on touring set up for pulling our trailer with our 20 ultra! Thank you!

My favorite channel on KZfaq. Great stuff Kevin. 👍

Another informative video, Thank you, Kevin, and I look forward to watching your upcoming videos!

Great video! As a retired Manufacturing Engineer for Waukesha Engines, Briggs and Stratton and Harley Davidson, your explanation was spot on. Can't wait to see your Shovelhead video as I owned one for almost 12 years.

That was very interesting video and again learned something about crankshafts .

That is certainly some excellent craftsmanship there. Keep up the videos. Take care.

Thanks for the education. It's good to see and hear the science and application.

Just want to say thank you for the knowledge you share with all of us. Henry , san jose ,California

Another great video. You could be a teacher. And that my friend is something that not a lot of people are or can be!

Thanks for the explanation. I always learn a lot from watching your videos.

Another great video. I have my crank at Dark Horse right now. Thanks Kevin.

Great info and professionally delivered. Well done.

Another great video Kevin, well done 👍

Another awesome vid with great commentry and info had this on my watch later list for a while,I know your vids are always worth watching so if I can't at the time I know to save them,I always learn something from your vids. Best wishes to you and all your viewers and subscribers, from, Auckland, New Zealand ⭐⭐⭐⭐⭐✅👍❤

My old hillclimbing dune buggy had a VW engine with a ^ pound aluminum flywheel. It was very fast to gain RPM and to lose RPM as needed on tiered hill climb environments. Good explanation of the flywheel function!

Sharing good knowledge as always thanks kevin!

On my next build I'm planning on a getting the crankshaft welded, trued, balanced and machined for tapered bearings. I think the knife edge cut would be nice, even if I don't notice. The death of race engines of any kind is crank bounce. that's what bluing, line boring, heftier mains etc. is all about. Anything that will keep the crankshaft rotating smoother seems like it will pay off in longer engine life. A nice even bore to stroke ratio seems like a good plan for long living engine too. I keep looking at the T111 engine for my 2011 Street Glide. Might be my build plan already put together.

Great explanation Kevin 👍

there is so much to learn thanks my friend appreciate the content

Very well done, sir. I learned a lot.

Really interesting subject...i had an old racer tell me about this along time ago he said he would fill the holes with cork. Now this was in the 70s and he was racing dirt bikes.... my street glide is a daily driver i don't need a built engine to gotto work and back i want it but i don't need it lol

Another great video of what's going on inside the "belly of the beast". There can be trade-offs to any modifications made. I like to remember that Horsepower is the rate of work being produced. Spin the crankshaft to achieve higher RPM. More Horsepower produced.

Thanks for the information 👍

The crank rotates 405* to fire the front cylinder Think about that. 0* Rear #1 TDC Fires 405* later #2 the front fires Thats a lot of rotation with out a pulse from another cylinder to keep everything in motion, You need a heavy flywheel in a 45* V Twin

Like my knife edged “A” balanced polished, light weight crankshaft in my Ducati 996. Since it has a separate “flywheel” but “built in” counter weights, we elected to leave the stock weight fly wheel, and instead lighten the counter weights of the crankshaft as it is what is slinging around in the oil. But we built that for 5k-10k rpm operation, making 150HP, from less than one liter displacement. It saw track days, but also some street riding as well. Although you had to be smoother with the clutch and throttle from a stop, I was pleasantly surprised how well it handled the street duty.

Hello Kevin great to see you

Thank you Kevin

Perfect explanation, thank you.

Great info thanks.

Love your Work 💯👌

Awesome in-depth info there Mr.Baxter. Thanks for all your informative info, can’t wait for the Shovelhead build. Be good to get back to some good ole school stuff! I still have a 77 fx custom, and a 13model Road “Rocket” Glide.

I keep the weight. road racing lighter drag racing heavier good video Kevin

Excellent

Nice looking crank assys! I wonder what a twincam 88" short stroke crank would be like under 110" big bore pistons, lightened and knife edged crank would be like? I know to get the rest of the engine to like it would be very expensive but in a light bike could be fun!

👍thanks Kevin!

Very interesting

HD lightened their crankshaft assembly by approximately 5 lbs, I believe in 1972. Reason being, the introduction of the Honda CB750 sort of forced them to have a quicker acceleration than previous shovels with heavier flywheels. What you should have mentioned is solid vs rubber mount applications. One of my rides presently is a 1980 shovel de-stroked to 74 with T&O torque monster flywheels, The smoothness (on highway) approaches that of a four cylinder bike. On the other hand I've had a couple of FXRs with lighter flywheels and those were as fun as a Sportster with quick revs, but with better long distance comfort. Not one can do all perfectly, just suited to my taste.

One thing we definitely noticed in drag racing was a lot more broken drive line parts when everyone was on the light flywheel kick. Apparently, a heavier wheel absorbs that hard power pulse a bit better.

Love your informative videos and learn is unlimited watching these but I have 01 cvo roadglide did screamin eagle tensioner upgrade and oil pump now if I get on gas pretty good oil dipstick blows out rechecked everything thing I'm at a loss whats your thought?

Love from DeKalb Mississippi USA 🇺🇸

Hey Kevin, can you do a video of the difference between the 113 & 120 twin cam packages on the website? Both list 110-120hp and 125-135ft lbs with 40mpg…what’s the difference? Thanks! Erik - Oregon

Great video. Is anyone coming out with an aftermarket oil cooler with a fan that is plumbed corrrectly for the m8 bagger?

iam confinent your the man for the job i mite just ride bike up.to.u and let u do the whole job i rather pay for your professional knowledge

After decades of testing there is no horsepower/ torque advantage or disadvantage of lighting fly wheels, doesn't matter if it is squared edges, knife edge ,pork chop , just acceleration

How well this affect pulling long hills? Seems the engine would lose speed and momentum faster with a lighter flywheel.

love it

What about if and why the Balance Wheel being removed on the M8? 🏍💨🏍💨

Kevin. Need your opinion on cams for the twin cam 96 mtr. Just listened to video by Gixxerfoo. He gave the following bolt on cams to consider. Wood 222. Hp 94.54 Tq 105.87 Wood TW 555. Hp 96.21 Tq 101.27 Wood TW 6-6. Hp 92 Tq 103. What's your choice?

has anyone converted a v twin to a single and if so what did they do to the crank?

I wanna know how to get 100hp out of 96ci stock.

Not to be off topic but I have a question about heat. I have a 2021 Tri Glide that is about to turn 5000 miles. I have been an Amsoil person for many years and I slresdy have my Amsoil kit ready to go along with primary and trans oil. My concern about the 114 is it a very hot running engine especially in traffic. It is a stage one with cat removed and SE air box along with American Custom mufflers that have been gutted with a mess replaced in the wells of the mufflers. I am running 4 inch baffles to cut some of the sound down. The Trike runs great and more power than I need. But, will this engine burn itself up with all that heat? I had a Twin Cam 96 before the Trike with a stage II kit. It was never this hot. What do you think?

Why does the pin need welded?

Hi Kevin!

good afternoon

👍

ive been watching your videos for months when its time to redo my motor frist my o7 road king i want u to rebuild it i watched your vidio.with the flywheels dark horse vidio.i want my motor done with timkin bears like u do and counter balance removed not looking for lots of speed as i am a motor built the rite way i want flywheels that dont have runout and i want .better engine parts ill pull my rdking.motor frist abd ship it to you.then my 14 ultra

Damn rough night or just woke up?

Kevin, now you did it, everyone's gonna want you to make their flywheel assembly lighter. You know what they about a little knowledge?

🏴‍☠🏴‍☠🏁🏁

School’s in session.

🚲🚶💭 👍

I respectfully disagree; a lighter flywheel allows the the engine to change its rotational speed faster but it doesn't add horsepower. Flywheels store energy, not generate it. Theoretically it increases the power-to-weight ratio but on a typical motorcycle this would be unnoticeable.

???????

Good stuff can't wait

👍
