- How To Add HORSEPOWER To Your Harley. In this video I explain how you can find hidden horsepower in your Harley Davidson Engine. When you do your Harley Engine Build Twin Cam, Milwaukee 8, Evolution and want more horsepower, here is a way to have it but there are trade offs. Lightening Crankshafts will make more power but you may not like how it rides.

Well I won't be reducing the weight, but I'll sure be getting the crank welded. 👍🤘
Great information kev.
Kevin, unfortunately I missed the premiere, but got to watch it later. Another informative video. Thanks for the info.
Extra points for nailing that "just rolled outta bed look"
😆🤠😄✌
You are an excellent teacher. I'm 62 years old, but I didn't understand the subject until now. Your approach is perfect.
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?
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.
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 .
Worked for Harley Davidson for 19 years. Love your channel.
Never had a flywheel assembly explained in more detail like that. Flywheel assembly is very interesting.
This is one of the things Erik Buell did to his Buell XL motors that is often overlooked.
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.
I’d love to see an Evo build from bottom to top!
Here,here, I second that! (Please and thank you,Kevin).
Just want to say thank you for the knowledge you share with all of us. Henry , san jose ,California
Thanks for the education. It's good to see and hear the science and application.
Sharing good knowledge as always thanks kevin!
Another informative video, Thank you, Kevin, and I look forward to watching your upcoming videos!
Great info thanks.
Great info, I have been searching for details on touring set up for pulling our trailer with our 20 ultra! Thank you!
Great info and professionally delivered. Well done.
Another great video Kevin, well done 👍
Thanks again for your wisdom , you are indeed a wonderful teacher and I can't wait to have you build my twin cam .
Very well done, sir. I learned a lot.
My favorite channel on TH-cam. Great stuff Kevin. 👍
Love your Work 💯👌
Great explanation Kevin 👍
there is so much to learn thanks my friend appreciate the content
That is certainly some excellent craftsmanship there. Keep up the videos. Take care.
Hey there buddy I'll see you Tuesday morning
Thanks for the explanation. I always learn a lot from watching your videos.
Thank you Kevin
Perfect explanation, thank you.
Thanks for the information 👍
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.
Excellent
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!
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 Kevin!
Another great video. I have my crank at Dark Horse right now. Thanks Kevin.
Hello Kevin great to see you
Very interesting
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.
bad to the bone
your like mei love old school.and with kevin doing the motor can u amgen the shovel motor after he is finished with it lord u no it will be bad to the bone
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.
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.
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 ⭐⭐⭐⭐⭐✅👍❤
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
love it
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.
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.
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!
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.
I keep the weight. road racing lighter drag racing heavier good video Kevin
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?
Hi Kevin!
👍
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
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
good afternoon
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?
What about if and why the Balance Wheel being removed on the M8? 🏍💨🏍💨
How well this affect pulling long hills? Seems the engine would lose speed and momentum faster with a lighter flywheel.
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?
I wanna know how to get 100hp out of 96ci stock.
has anyone converted a v twin to a single and if so what did they do to the crank?
Damn rough night or just woke up?
Lost his hairbrush..
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
I was going to say the same thing. It only allows the engine to rev faster more easily. The only was a crank can add horsepowers is by ….. wait for it …… wait for iiiiit….. yup you guessed it. By stroking the engine! Period.
@@EARDRUMASSASSIN Not necessarily correct. Increased displacement gives an engine more potential, but if you can't flow more air, burn more fuel or compress it more, it won't in and of itself, make more power. Only two things really affect power output. Moving more air and more efficient combustion. The angularity of the rod in a stroker definitely affect its personality. Not necessarily it's power output.
Why does the pin need welded?
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
🏴☠🏴☠🏁🏁
🚲🚶💭 👍
School’s in session.
Kevin, now you did it, everyone's gonna want you to make their flywheel assembly lighter. You know what they about a little knowledge?
???????
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
