#11 - DYNO RESULTS / 128' BIG BORE KIT BUILD SERIES FINALE / 2020 ROAD GLIDE SPECIAL

[@glencross4461]

Wow what a build!! Sweet and I have to say Dave deserves thanks for letting us see his shop and how he builds these awesome engines!🤙💯🇺🇸😎

[@cjkirk30s]

You should do a sit down video with Dave if you all get time and talk about all the different exhaust and cams and basically upgrades that he has found works or don't work etc. Would make for some good content. I like how he explains his work, great video and grats on your bike getting finished for this round lol (Never really finished).

[@cedriclashar8905]

JD...has always been known to be an honest wrench/tech...never tries to sell you what you don't need...your bike is now a reliable street monster!!!

[@shdbmw]

Dave is the kinda guy we all need to work on our bikes I’m in Carlsbad CA. Wish I was closer I would be dropping my bike off for sure!!! My hats off to Dave.👍🏻👍🏻

[@thejerseyj9422]

Congratulations on a successful build. And, I have alot of respect for Dave's abilities. Guys like him are a treasure for us bikers.

[@kfacpa]

Just got my S&S 128 big bore kit with 540 cam... dyno'd last week: HP 137 / TQ 157lbs... I have ported fuel mote heads, HPI throttle body and manifold, Fuel Moto cat delete head pipe into the standard duel exhaust with Rienehart slip-ons. Tuned with TTS master tuner... So much torque that I hit a bump in the street and it jolts me forward just from bumping the throttle... (we're going to have to fix this)... I did a Barnett clutch upgrade along with the Dark Horse compensator and chain drive. In all honesty, I think you got more bang for your buck than I did, but I'm totes happy with my build... Thanks for the video!

[@HOLYSHIFT]

Wow - so much power gain

[@anthonysantora4924]

John, thanks for the education on the exhaust systems, it clarified any confusion. Ride like you stole it, which I’m sure you will! Safe travels.

[@zookskustomz]

A big thanks to Dave for letting you film the engine build. I really enjoyed the content and your camera skills are improving with each video. It's small indy shops like this that have set high standards for the V-twin market. I admire Dave's passion and would use his services if I was in the area. Cheers...

[@warricknorris5034]

I am in the process of looking at upgrading my 2020 Road Glide so I searched all things on youtube. I stumbled across your Silverback upgrade to a 128. Just want to say it was the best series I’ve seen on what I’m interested in. Also it is plain to see why you use that shop to undertake that work, very thorough, honest and professional. I’m from Australia and want say well done good on ya mate!

[@madmike8v72]

There's so many things about this bike that are unique and cool! First it sounds amazing and on that 1st pull you could really hear it come on the cam on the top end, second the gloss black against the silver and the accessories you chose like the seat and rack , air filter, it all pops!

[@timdavis8154]

Enjoy that seat torque and hang on. Great exhaust info too.

[@rosseiring6276]

Tree man here. What a monster. Should be a blast to ride. Looking forward to seeing your videos 😃

[@MrCRM2011]

Outstanding numbers John. Hats off to Dave for a job well done. If I lived there he would be my guy 👍🏾

[@DiverDown2Deep]

Great work Dave! Thank You for being so transparent. A true testament to his craft. I want to trailer my bike there for him to do work next season.

[@adamriley8731]

Great video my 128 got a 540c cam made 131hp and 158tq going to do the ported heads next try gain a few more

[@dyna06rivera73]

Great job by Dave! Sweet ride.

[@DarkHorse82]

Dave is so awesome!

[@stringing4life]

He will be building my bike when I'm ready.

[@shasiceruti8994]

Congratulations! Awesome John be safe on that beautiful beast 🤙🏾🤙🏾

[@josephmirigliano8728]

Great 👍🏻 video glad you got your bike back

[@JonV-r7q]

I totally agree with Glen Cross. Great build guys Thank you both for putting this out there. I will try and make the open house in May. John do another build . LOL!!!!! This was fun to watch.

[@innovationgroupofsouthflor4744]

Great video. Dave is amazing . Great job!

[@Greg-ks5vd]

What cam is this bike running

[@patrickstevens5457]

Neat to see the excitement and thrill of the science and art.

[@robertspencer2917]

Enjoy the ride. Someday I will do something with my twin cam 103 ultra limited. I need to update my bike pic. Thanks for sharing this bike build.

[@Funzy34]

Congratulations Bro. 👍 Sounds awesome. Need my Cam done on the Street Glide 😂 Need that 475 LOL

[@vincentrowan2846]

Great video couldn’t wait to see the end product that is one screaming machine be safe👍👍

[@kj8779]

Dave is the MAN!!

[@cabby316]

Those are awesome numbers for such a sweet build, cheers man, 😎😎😎

[@robertmacdonald2735]

Great marketing your doing for JD....plus great content....

[@darrankidwell193]

Wow, Dave is a Bad Ass! Absolutely enjoyed this video series. I have to say this is the best series on building a m8 engine on the tube. Thank you so much for taking your time and creating such great content. Also I took your advice and having dark horse compensator on my build. I am doing similar build on my bike (2019 heritage) . I should get my bike back on 4/15 so watching this video helped me understand why I spent so much. Look forward to seeing you put some rubber down on your next video!

[@diegoj.1501]

Is crazy brother,amazing job sound like best....congrats 👍

[@edwinparedesnjusa]

Good job on that build 👏, definitely coming for the breakfast event. 👍

[@RGHD912]

Nice! Great numbers, it’s going to be a lot of fun

[@tommiller8714]

Excellent Torque and HP peak numbers and [more importantly] the curves, especially the Torque curve. "Bravo Zulu" (well done)!

[@harleyscootsandcowboyboots9781]

Great #’s your gonna love it!!!

[@leftoutmn]

Love hate with builds like this. Love that there are honest true to the core love what they do for us mechanics like Dave The hate is, wish I could find a shop like John’s here in Minnesota. I love my guys at H-D and completely stoked with my upgrade from my 103 to a 110 stage 4 but builds like this have me thinking of upgrading to a M8 and a 128 big bore. Get the ride along uploaded. I can’t wait to see your reaction when you twist that wick. Thanks for letting us ride along through this process.

[@Sodiumfreeriding]

Heck yeah man, you’re gonna like that! Good stuff

[@zookskustomz]

In all my big bore builds, I install a fan on the oil cooler. I would recommend you have Dave install one for the Main Street Sturgis/Daytona type of conductions.

[@kfacpa]

I did a Jim's Force Flow cylinder fan, so far so good... still on the fence thought between this and an oil cooler fan...

[@bigken62]

Very nice vids Dave is a rock star I live in MI and if I need some work done he is on my list Keep Up The Good Work

[@FLYANDRIDE15]

That’s awesome power! Congratulations! I’m up for meeting there in May 8th, will be in touch prior.

[@jamescantlin1072]

I would love to have his smarts when it comes to motor work ! Your going to love it!!!

[@HudsonMoto]

Awesome video! 👍🏼👍🏼🔥🔥

[@douglassherman6842]

Awesome looks great , enjoyed the vedios

[@martyoneil9975]

Wows! Thanks for the video!

[@HolyPerformance]

Is there a parts list somewhere for this build? I can't seem to find it

[@geraldgoodiii6993]

I have the KW 2-2 head pipe with tab slip ons (medium baffles) and it performs very well. Tq curve looks like a table top with a gentle rise up to peak tq. No dip anywhere

[@emeraldcitycarpenter]

Nice results 💪🏾. Great build series.

[@alexaguilar861]

i’ll be bringing my bike from Boston to dave for sure

[@Annonymous0283745]

I know I'm a couple years late, but who makes those handlebars?

[@levidavid09]

I’ve called Dave (super nice guy) and we talked about my ‘19 RGU 117". He told me what KW baffles to get so I bought em. He told me to use the tts200 cam. But… I went with woods M8-408 instead. I’m glad I did! My bike makes 135hp and 132tq. I’ll do the 128” kit later!

[@20sgcvo90]

What baffles did you get? I have a 20’ SG CVO and just got KW 4.5.

[@briannorwell202]

Question: Cruising down the road say on cruise at 75 mph, does the exhaust leave your ears droning after a long ride?

[@matrixfd433]

Badass. Gotta get with him after my deployment so he can work on my RGS.

[@brandonmartin506]

I’m pretty sure the 124 he was comparing is my bike love the power it puts out but one of my zipper pistons cracked putting s&s 124 now hope to have better luck with s&s.

[@brandonmartin506]

I never met Dave but the guy who sold my bike to me said he knows his bikes. I hope to go to Pennsylvania and meet him someday I actually live in Arkansas.

[@3rdgearmoto]

Excellent series!

[@Realniggatho24]

Wat harder System did you go with

[@hectorsantiago321]

Ask him if he wants to sponsor mine. Dammm that’s power. 👍👍👍👍👌

[@ronmartin7959]

Curious what he thinks about the tab performance exhaust with zombie baffles using the V&H power pak duals

[@DavidTorres-xl2jl]

Curious to see what he thinks about the Tab performance exhaust

[@picamiolos1000]

Great videos all the best for you guys!!

[@paulmallet7899]

Hi What cam are you running?

[@AngliaNutz]

Why is my local dealer discouraging me from doing the 128 cu. in. big bore kit with camshaft and supporting exhaust and intake along with 55mm intake manifold on my 2021 Freewhweeler trike?

[@craigc79able]

I can’t get out that way to support such a great shop. But if they ever sell T-shirts or sweatshirts I’d be happy to buy a couple

[@thejerseyj9422]

It figures it would be wet the day you pick this beast up !

[@edwinparedesnjusa]

That dude us the best 👌 👍

[@freedom6919741]

Shoulda had the crank done. It will go eventually. Ask me how I know.

[@harleyhawk7959]

Freedom Rider. having my twin cam that I had a ported and a big bore kit installed when I bought it new. Now I'm having it bored and stroked,S&S geared 510's. S&S balanced crank. new valve springs.

[@johnburk5748]

Awesome!

[@BrianLarson1326]

You ought to update the links in the description

[@tonyforrest631]

Great videos, enjoyed watching them. I really thought you'd get better numbers out of that build with the M8.

[@wardamberson2535]

Very nice sounding bike seems like Dave knows his stuff forsure. Do mind saying what is the total cost for this work? He did I have 2020 love to do this maybe ship my bike to him.

[@CYCLEFANATIX]

Really, not sure the of the cost.

[@JUNIOR37996]

Hey. Why did you change from the 2 into 1 setup?

[@dagooglenet]

How much would all of these cost coming from stock to 128? $5k? $10k?

[@brandonwarren1995]

Do you have stock heads ?

[@CYCLEFANATIX]

Yes

[@medicinemanfranco]

What kind of price range for that 128 up grade?

[@Znd93Rus]

power drop on high rpm more looks like throttle body closing not heads limitations. I saw it a lot on RDRS equipted bikes.

[@justal4930]

Are you trust about the stock flywheel lifetime ?

[@jamesatkins3616]

Yeah I did 128 inch build and I pulled 144 foot pounds of torque and 150 hp

[@TheJourney-25]

Nice numbers. I’m really curious what he thinks of HPI exhaust. I’m looking at HPI one day

[@Hellbentbiker]

What baffles are in the khrome werks system?

[@Hellbentbiker]

@@CYCLEFANATIX awesome! I appreciate your reply. Is this the set up Dave recommended? I’m going to see him soon to put the tts 250 in my 131 build and he recommended khrome werks and I got wondering about the baffles used so I purchase the right system. Thanks again

[@kingkole02]

Close to what my 92 cu victory makes with only an air box and pipes with a tuner

[@brooklyncvo7525]

He knows his shit I wish I didn’t have the extended warranty or else my cvo would be in his shop getting worked

[@harryhowell5644]

That's a lot of money to build. I hope this holds up well for you. I got over 4 grand in my ultra and it's only stage 2!

[@davidincle7166]

Im sold ... I know where im going for anything I need done on my 2017 Street glide....

[@fargusmcfargus3523]

Dave Rock's! Save your pennies up and go ahead and get the heads like Dave said it solves a few other issues sit down and talk to him about it, it'll be worth it especially for Silverback With Throttle Crack!

[@paulhorvath9784]

A.P.E just did a 128 Fxdr that ended up pulling 9.84 @ 133.81 mph,,all Stock Cases.. Yours should be up there even so..

[@uwe.pegasus]

Why did you turn off automatic translation? My English is not that good, so I have everything translated into German. Can you activate it again?

[@alfonsothegreat4481]

I live in California, Bay Area. Where can I find a technician like this one that has the passion and knowledge to tune my Harley-Davidson???

[@rosseiring6276]

tree man here. hey john it looks like the dyno tested more than the motor. from what I can see in the video there doesn't appear to be any bluing on your pipe before the dyno run. I just find that interesting. did the larger displacement do that?

[@ScottyLo]

What a difference. I have a 2 into 1 exhaust on my 05 RG. It’s a dirtybird concepts up yours and I wonder if he’s got any experience with one

[@cruisinwithcannibal7280]

They don’t make power at all more for the look had one took it off went with AR design by Thrashing supply huge gains

[@TheRoadking1973]

My question is do the M8’s perform better with dual exhaust 2 into 1 into 2, rather than a 2 into 1 ? As far as performance? I always thought 2 into 1, like D&D gave you more TQ, or is that just on twin cams ?. Almost seems like the M8 likes more back pressure than the twin cams. Was just curious about that, thanks for sharing this build, keep up the great content.

[@cedriclashar8905]

Wow I wasn't digging the wrap at 1st...but I have to say....John...she CERTAINLY does look good with the silver...it's tough when you don't like SOMETHING...but the more you see it...the more you have to submit and just have a change of mind 🤣🤣🤣🤣🤣...I had the same ISSUE with roadglide fairings when I bought my bike in 04...and now I'm going to convert 2 of my bikes to....wait for it....ROADGLIDE fairings...WTH😁

[@davepelfrey3958]

Now, just think of the power if you add a Trask turbocharger on that thing. I watched a video where this is a bolt on and add anywhere 50 to 70 hp, That's crazy in my book.

[@freedom6919741]

What cam is in it for the 10th time.

[@freedom6919741]

@@baggertrash1327 ok thank you. Very good cam evidently. I am running the Zippers 472 with stock heads and throttle body on my 124. It made 132/145. This bike made really good power.

I have a Stage 1 107 Milwaukee 8. How much $ would it cost to do what you did on the video?

[@scotty2221]

@barney desimone I can afford anything, just wanna know before I leave them my keys. If under 10k I'm game. If not then it's just not worth it.

[@scotty2221]

@barney desimone Cool thanks! I bought my M8 to put about 10-15k into it so that sounds about right. It's my first HD and wanna make it as much fun as possible and comfortable. Gonna do the shocks and upgraded Stereo this summer for sure. The bigger build probably right after then once I find someone with the time.
