My wife saw the title of this and gave me the most threatening look I've seen since I did a burnout on our brand new driveway 😂

"It was pretty easy to get this much power" Yes Sean, money does make things easier.

Haha, Sean...."The simpler they are, the better they age!" Now let's stick in a bigger engine and add the biggest, most complicated turbo system we can find. Keeping it simple??? Love it!

I’m pretty sure the whole old man sleeper look is gone when your Harley sounds like a Powerstroke lol

I saw this bike in Daytona and Sean fired it up. It sounds so good. Beautiful bike and beautiful build. Sean is also a really awesome guy in person just like he is in his videos. Love the words of wisdom

Sean, you nailed it again, love watching your channels , learn something each time and because of one of your earlier posts, I have been riding the perfect bike for me . Plus doing a few mods myself to get it running better. Keep posting

Hands down one of my favorite builds on KZfaq so pumped to see this Bike come together

This is the sickest street vtwin I've ever heard or seen. Beautiful bike Sean, keep posting more videos of this bike

I’ve always been a snort bike type of guy and I still am I have a 2020 FZ/Mt-09 but My grandfather left me his 2009 Harley Davidson Screaming Eagle CVO softail springer and I could only imagine throwing a turbo on it but I’ll never change the way he left it. Wouldn’t get rid of that bike for anything in this world. I absolutely fell in love with riding a Harley because of him.

I still maintain that you should add a boost controller to the system, so you can easily switch between pump gas and race gas power. I run the Turbosmart eBoost controller on my 96" 2011 Fat Boy. 179hp/181tq at 14psi on 91 pump gas with ACES IV additive. I haven't bothered to turn it up more and run C16, but before the boost controller, it did make 18psi on C16 and made 201hp/200tq and captured the 1650cc A-PBF record at Bonneville at 167.435mph. That beast should go as fast as you're willing to ride it.

I love that it still has a mostly stock look outside of the turbo. Looking forward to the suspension mods. Would love to see some carbon fiber wheels to help get that power down.

10:27 Your camera bike is a Valkyrie!!! Let’s go!!! 2000 F6C owner here!!!

A great inspiration to us all, thanks for sharing Sean :) I ride a 1995 Suzuki Intruder 1400, probably making 72hp and 94ft lbs of torque, I never dyno'ed it I just copied the modifications someone else did who dyno'ed his bike. I wouldn't mind having double the power, basically I want to be worried about pulling a wheelie or frying the tire if I hammer it and it currently does not. Maybe I'll try to turbo it for fun, either way you have a fricken cool bike man. Can't wait til you're comfortable to initiate a 0 - 60 :)

I was skipping around on your video and got whacked by some Proverbs. Thanks G, needed that one. God bless you duder!

I have the same bike, but stock - and I get the same excitement you get. That said, it awesome to watch what you come up with.

I remember being a new viewer long ago and I always came back to watch your videos. Words of wisdom was the reason why. Great job!

I have the highest respect for someone who has the ability and guts to modify a motor intelligently and keep details like upgraded oil flow and power transfer in mind. We only live once and your riding days are not that many. Building the bike you want and enjoy is one of the pleasures most won’t understand. In the end, you are not riding a magazine review or someone else’s opinion, you are riding the motorcycle that does it for you. It’s a visceral thing that the lucky few truly understand.

Short Answer.... Without the turbo you staring down the Barrel of 28hp.....😅

Back cut gears and better clutch is necessary after that much upgrade. I got a 99 FLSTF Evo to put 90hp on wheels and that ate up the transmission and clutch right away. Fun to do😅

I love riding my cousins bike. Almost bought a VTX 1300 but the fuel lines were rusted. Hopefully one day I can save enough to get one myself. Love watching these videos

My 19' SG CVO is running 155/148 on 91oct (128ci) and the tq is too much for in town riding. We talked about putting a Trask onto it, but it would mean losing my lowers and I really enjoy my lowers (have the 6 speaker Rockford system + 2 10" subs in the saddlebags), so we decided to add a 2nd tune onto the power vision running VP 109 Reg race fuel (and upgraded the injectors again)...but we're still waiting on the fuel to arrive to see what it does naturally aspirated.

Being a parts manager, and owning two 131 crates myself (seriously I’m not trying to brag) I can safely tell you that they do not stamp the vin number on the engine. They just give you an MSO to put with the title. If they put the vin number on the engine, they would require you to send the crank case back. Which they don’t because they don’t stamp the matched vin on it

Helo form Mexico!!! You are my héro!!!!! I love HD Road King and your are the Real KING!!! Keep riding!!

Been watching your videos a while finally got my first bike at 27, 1968 t100c

Love your content, Brother. I keep trying to make vacation plans to go by your shop. I just need to find a way to explain it to the wife.😂 both you and Craig seem like the real deal good guys. Keep being awesome, fan from Canada.

Nice build. Torque is always the answer ;-) Loved the Proverb!

It's great that there are reafy kits for these torque v-twins. I have a 1999 yamaha xv1600 that i turbocharged. Even with 100hp and 200nm from tire, it's SOOO lovely in nature! Having close or over 200hp is great!

This is the most entertaining/ good vibe content motorcycle channel

I’ll take 1! Exactly the same. Sorry not trying to copy but that is truly an amazing looking bike all around including the performance it has. I’ve never seen a blacked out road king special from Arizona to Pennsylvania.

turbo'ing my Street Glide was one of the best decisions I ever made. I never get tired of it.

I started out as a motorcycle mechanic on the Japanese brands in 89 then added the European brands later starting with Ducati then adding the rest over the years but now most of the work I do is on Harley because im old and so are the people who ride them and we just get along well. I love all bikes and HD dose some smart things like make their fuel injection pumps accessible from the top of the tank instead of the bottom like everyone else but their inefficient oil pumps are something else. Maybe it is because the old EVO motors needed volume over pressure and they never got away from that design but HD is the only brand that needs a oil pump upgrade. We got close to 300 wheel HP out of a base model H2 and never gave the stock oil pump a second thought. I have done allot of HD oil pump upgrades mostly upgrading the 88s but lots for builds and they are such a bad design and inefficient. 10 times the size 10 times the parts and 10% of the performance as the metric side of things. I love HD new and old im glad they are getting in the adventure market as well I just want them to built a better oil pump.

Your Hp-gains , all-the-way-through, are very-impressive . I haven't seen such large-gains on any other motor with such little modification . This model Harley must be pretty-strangled (inlet-through-to-exhaust) . Normally , the first 10-hp is relatively-acheivable but from there-onwards it normally costs A LOT . A 25hp-gain on a 500single , could set you-back 10K . So engine-cost aside(crate-engine), you have done very well. Dave NZ

Can't believe how good that thing sounds. Makes me want to turbo my 2 cylinder aprilia tuono

Good video, looks like a too much fun to ride. Thunder Max isn't the only tuner for turbo / supercharged engines, Lloydz also has a tuner for their Supercharger Kits...thinking of upgrading my Indian Super Chief Limited which currently has stage 2 and a Lloydz tune.

Got my first Harley yesterday and I can't wait to build

I like my road king. But you're rk is crazy!!! Thats a wicked machine!!!

Street is all about torque. My turbo fz10 on pump 91 still only puts out 188hp but the spike in torque to 105ftlbs from 6k through 8k makes a heck of difference. Still struggles to keep front down to use it on street. But for anything below 100mph on a bike it’s all about torque and if you can get it told not brake loose.

You can turbo with Dynojet Power commander V ok. The exhaust two in one so early before turbo affects 02 sensors. Exhaust reversion makes it difficult to autotune but a bit of maths to even out cylinder one and two afr trims or on map results helps to overcome errors. Then adjust up untill it starts to glow red and back it off a bit.

This gets me thinking so much. How much of that bottom end ease could you get back with the cam going back and how much power would that cost? Would it be worth it? Please turn TC off. That cut must have put a lot of load through everything going on-off-on like that. I would rather it light the rubber than stress expensive parts. Only things I would really change are I would have to run it on pump (for availability), I would have backrests for both seats and I would probably go for black turbo and pipes to go with the bike. The stainless are more stand out and cool but I like stealth when its making big numbers. I remember all the haters when you mentioned 200hp and I remember commenting on when you do it I need a parts/cost breakdown so I can copy it. I still need that breakdown - at least for the parts. I'm also wondering what the cheapest RK I can get to put that motor in is since I'll be swapping pretty much everything anyway.

I love how titles on this channel went from DONT BUY THIS R6, to you NEED a turbo on your HD so you can have 260 HP! lol. Love you guys, keep up the content.

Good veidio Sean, nice you do info on, different style bikes, just seen , veidios on Busa an zx14r, nice stuff, glad you still hang on to 200 + hp, be safe, keep the good,stuff, comming😎🤩

I like the sound of this bike, it’s rumbly but not crazy loud due to the turbo. A very cool build overall…

Turbo or not,Black Road Kings are my favorite as well. No radio,just a speedo on the tank and that great sound!

Very impressive numbers. I just bought a Kawasaki zh2 which is factory supercharged and I love it.

Great video! Can you also make a video about the camera bike? Thats a naked Goldwing, right? Greetings from Germany!

What size turbo and wastegate? Also any ring gap change, I’m gonna build my own

Buddy! You are back!?!? Great! Good speaking to ya!!

Did you get to the Fast Eddie Fisher's auction a few weeks ago there in Pennsylvania? I watched a video on his life. What a great racing career!

Best yet. Its one beaut' of a baadazz moto. This coming from I'm an ol' 1800xc hooligan. It dusts pretty much everything but, my hatz off to that baadazz moto you done up. Great job brah'. Youre livin' the dream. Stay well ! Ps,... moto i owned before the Xc was a 10 second flat VMAX so you can get it down to 9 im sure.

Do you guys perform this type of tuning to the public? I own a 2013 Honda CB600F (Aka Hornet) that I really want to put an big turbo in it and a few other adjustments just for fun and maybe try on a Drag race somewhere from time to time.

how about your machine vs rocket 3 the fealing =) ? similar your harley even pull harder ?

I love how you say it was pretty easy, to get 260hp, well its always easy to pay someone to do it for you ;) (Yes i did follow the build, it was pretty good to)

Absolutely beautiful bike. Stay blessed, brother!

I love how you break out the ole Valkyrie to be able to somewhat keep up 💪

I rented the same bike in Florida and it was pretty quick but definitely felt like it needed more

I'm in massachusetts. Got a 08 zx10r if your ever in the area we should meet up and see what that road king is capable of. Would love to see it in person and love the content you put out.

I can not wait to see this bike at the track!

Sean, do you have long cuff gloves that either tuck into a jacket sleeve or that you'd tuck jacket sleeves into?

Have to say that I'm not religious, but do enjoy the proverbs you use. They always seem to be a nice little touch to the videos

That's some good words of wisdom today. 👍

I like that your chase bike was a Honda Valkyrie , I think its probably one of the best looking bikes out there

The matching numbers thing is awesome👍

What breaking system are you going to have. Surly that's something it really needs as there's just no way the stock breaks are good enough for the bike as it is now. If you want it to be fast on the track as well as the road then Breaks and suspension are possibly at least as important as the power upgrade you've had done. A specialist ECU would probably bring a huge advantage as well, I don't know if getting such a thing is even possible and if its not is hacking the one on the bike already and making some useful changes to that instead something you can do?

It looks like the pie making machine. From the movie chicken run. I like the matching numbers that’s great I appreciate that too. I ride a Lowrider s Shawn and I ride it hard and I can honestly say it is a really good balance of handling brakes and performance. I wanted to do something like this but I didn’t think it would work on my DYNA. More power the brakes wouldn’t be good enough it on the limit of its handling. It’s a perfect balance of everything. I had a hayabusa turbo hardly rode it. I honestly believe it was a better more usable bike. The upgrade in power made it unusable and horrible to ride. Hope you don’t have the same problem. I’d be tempted to try a super charger because of the smooth delivery from tick over too top end. Be careful my Suzuki though me out of the seat a few times. You’ll find out what I mean.

Genuine question as a car guy. How high do these cruisers rev and where in the rev range do you hit peak power and talk?

My bike is stupid fast with 150 hp and 78 lb ft torque. I couldn't imagine riding that beast.

What’s the GPM (gallons per minute)?on that thing?

Bro, you still have the warning sticker on your mirror 😂😂😂 Awesome bike!

Does turbo any good for long rides? I heard some people say might be heat the engine very easy.

Is it C16 or Q16 that is the non intercooled fuel ? I always forget

Have a question for you) how do you deal with the enormous amount of heat that it produces!!!!??? And how it harm the motor? Because I always afraid of that heat and don’t want to damage the heart of my FXSB boy) Thanks in advance

RH mirror still has the sticker on it that would be removed on PDI. You've swapped out an engine and gone turbo without riding it much?

Turbo definitely most horsepower for the money but any engine mods very expensive vs just buying horsepower from the factory which Harley does not offer. You need more torque with a heavier bike vs a lighter bike. What is the redline? Higher the rpm the more pull?

Love my Road King I bought from Sean at SRK Cycles. They wee great to do business with. I will by again if they sell bikes again. Sean is crazy with this Road King.

I just bought a Nightster 1200, but it needs a voltage regulator and a stater, I think I can fix it but idk, I just bout it for 4k has 9200 miles and only got like 60 miles on it before it broke on me. I live in PA and Hanuums is close to me but they are so dam expensive and the last bike I put in they had for almost a month before I got it back.

What’s up brotha hope all is well and the family is great

More vids on this build! It’s absolutely epic 😂❤

i have a stock gen 1 Hayabusa 164 rwh that is 3 inches over stock that runs 9.50s in quarter good luck and street legal also have Gen 2 busa with small turbo street bike that runs in 8s off the street .Hopen to run into that Big Dollar Harley.

Awesome bike. Nice to see you doing another video !!!

I like the way you adjusted mirrors, right covered with a sticker and left inspecting the neighborhood 😅. Great bike with great mods!!!! How is your WLA project going?

Hows the turbo lag? Also how is it downshifting into a turn?

Did the manufacturers for your chain and wheels give you a max torque load rating?

Shawn do y’all not sell motorcycles anymore? If so where do you look at the inventory?

What kind of turbo do they use ? A T3 with integrated waste gate ?

those slow light throttle maneuvers should be tunable. the ignition table in that section has to be very smooth otherwise the transition between on throttle and engine braking will be jerky

I would really like to find a Harley like that to do a 50 or 60 roll with. Well both spin on a launch, but I can start in 1st or 2nd at 60 and be pretty close to the power band (or the beginning of it). Just to see how different the acceleration is compared to a stock hd, or even a stock 1000/busa, etc.

Love that the chase bike is an old goldwing

Yo, I would love to see videos of y'all in the shop and stuff like that

It does look like a lot of fun and a beautiful looking mod. One question I have is are you going to overwork the transmission and the final drive with all that extra horsepower? Will you be snapping drive belts for example? You did address the clutch issue because I had that question and I’m guessing the stock clutch will start to slip soon, even maybe with heavier springs? Anyway, enjoy

The fact new 2 piston engines are beating some old v8 engines is amazing

You have another Chanel!!!!! Subscribed fosho!!!!😂😂😂

Best road king on you tube....even the old man's from moonshine Harleys that was only 180hp....

The belt or chain was on my mind from the start. Is it really $6,000 for the turbo?

It does still weight 800lbs without rider tho yea? Id be curious to see hp/weight numbers compared to some other bikes

Is this so it will keep up with every other bike over 500 cc?

Does it leak oil more if u keep full sending ?

Beautiful bike brada!! Road King!🤙💯

Hey man see you like your bike did you know orca cycles has a 350 HP turbo for 131ci with inter cooler that's the place you go for big HP .no dynoing no mid range sputters .check it out they have 350 HP bike you can test ride with 6 piston brakes runs on pump gas there you go

That's a bad arse bike. I'm not a Harley guy (I like Italian bikes) but I've been having an urge in my heart for about a year now for a Harley.

Sean, that RK deserves some new suspension and a seat that will lock you in the saddle; and some bars would go a long way. WAIT A SECOND, WHO AM I TO SUGGEST THESE THINGS?! GOD BLESS THAT BEAST, SEAN! Ride safe brother HA HA - I SHOULD HAVE FINISHED THE VIDEO BEFORE I COMMENTED!!!!
