Inverted forks with dual disk. 👀 hell yeah

[@vinniemadrox]

When you finish and get some miles on it, I'll be curious what you think about this hammer performance kit vs the hooligan kit from the giveaway bike.

[@ivanrivera5130]

What color did u order?

[@love2fight205]

@@ivanrivera5130 Purple #32

[@delallum5654]

What a beautiful build! These black and red color combinations, great engineering on motor, the sound found and the performance boost 👌👌👌😎👍👍👍 amazing job!!!

[@MontesMayhem]

I absolutely LOVE the XR 1200. Rode it once in Alaska around 2010 and I've been all about it since.

[@stinde666]

That’s a cool bike ,Sportsters RULE 💪🏻💀

[@hd01roadking]

Awesome content on performance upgrade. It would be great to have dual front brakes. It was very informative. Thank you!

[@roberthunter4418]

Looks a lot better with the drag bars, good choice!

[@MrDrywaller1]

I bought an 883 just for building. Currently have done a suspension lift, seat, bars, air cleaner and pipes. Not getting too radical but the 1275 kit is on the list.

[@thornrob]

the $30,000 Iron...haha love it!

[@BlockheadMoto]

I don’t keep up w how much we spend but I know we’re nowhere close to $30k 😂 Under $10k def

[@Firestorm637]

KRUESI Originals, in Phoenix, switch to chain drive. Oil cooler fan also. He builds stunt bikes. Harley needs more aluminum and carbon fiber replacement parts. Glad to see new Sportster with engine used as stressed member of frame to decrease weight as well as stiffen frame for handling.

[@RTJsims]

Dude! Chris read my mind! With this much power, twin front disks are almost a must. This bike is getting sick A.F.

[@Underbottom.Sandydown]

.... and a chain?

[@whskywolf]

That bike really looks good, love the color. I cannot imagine how over 100 hp feels, my old Rk with twin 88 throws me back and it may have stage 1 and that it.

[@MrJruta]

Yes!! Drag bars!!! 👍👍👍 This bike is, has been and will always be my all time favorite 🏍 Love it!

[@Chase_N]

I had a dyno tuner swear by the round air cleaner kits & recommend the gasbox custom AC with TC Bros breather bolts. He said the cone filter air cleaners can't suck enough air & cause turbulence where the round ACs don't & are capable of providing more HP & TQ. I did what the old guy said & my bike did better on the dyno by 5Hp.

[@BlockheadMoto]

I think the 51mm throttle body we’re doing comes w a round AC

[@Paul20661]

Wazzup Block watching from moto camping ⛺ we have festival this weekend 😁

[@karloaugilazupan3282]

I got my motorcycle license today and getting a Harley 1200 on Sunday. Thank you for the instruction's on the OG.

[@TeddCookerly]

I think that we need to ask Chris more about his skateboarding days. Sticker on the toolbox tall a different story about how sick he is.

[@simpleman5583]

The bike looks awesome - in addition to the performance. Great job.

[@YatiMoto]

Atlas 3.0 carbonized inferno will really go great with this bike! 👌🏽

[@slayer04031974]

Mustang high rise seat!! Fabulous for us old guys. Lol

[@beardwrench]

Call Brock's and get them carbon wheels with ceramic bearings

[@Nifilheimur]

Doing all that with the engine and still have a belt that robs some 15% off your power compared to a chain drive at some 4-6% sounds kinda weird to me! Plus chain looks way way better:D

[@calincampbell5637]

Is there a kit that converts to chain drive?

[@Nifilheimur]

@@calincampbell5637 yeah tc bro’s have it and others also

[@BlockheadMoto]

We do the build in stages to showcase what each modification does in terms of power. We’ll be going chain drive and it’ll have its own episode to show actual before can after numbers

[@Nifilheimur]

@@BlockheadMoto awesome👍👍 will be fun to see the difference. Starting to miss my old sporty watching this series😅

[@matt_xlns5248]

@@BlockheadMoto make sure you address the axle adjusters, they WILL break.

[@Cowboy.underwater]

A GSXR front end would be sick. Get some proper shocks out back to match and this thing will be a track day terror!

[@ecrusch]

Man - O - Man !!! You can just tell how fast it is by watching the video!!! Holy Smokes !!!

I’m in love! Definitely need a sporty now

[@Ridehighfxdb]

Man I can hear the valve train noise through the camera while you ride haha those cams doing work with that big bore kits

Wow! You are going to have a giant killer, "AWESOME"!

Y’all got some fire playin in the garage tho

[@onlyhereonce7290]

A great video series. Very fun to watch. And learn. Thank you so much. Go with the GIXXER front end.

[@lassei4659]

7:06 with that superview on the gopro, that beast looks fast a hell!

[@championofkoss7743]

That is SICK mate!!!! Definitely a godly bike 😤😤😤😤😤

[@billcobb9408]

I ran 2000 buell fly wheels. the case was bored out with a flex plate on the trans.30 degree domed piston, S&S super stock heads, 2"1 intake valves. It should torque wheel at like 2,000 rpm just cracking the throttle. Sounds like a lot of fun.

[@nelsonmcdonough9418]

Love the videos! Looks like an awesome build! Best part was seeing that Block Beard! 🤘 Nice

[@Rugen12]

Nice hearing pantera in the background

[@emmettsmith9966]

I love your videos block, thanks for making my day better

[@BlockheadMoto]

Thanks for watching!

[@bombSQuAd412]

Rotation mass in your wheel is mass multiplied cut two pounds it feels like u cut around 20 out of the bike

[@billywebb9614]

You and the Snow Miser ❄ have that thing looking amazing.

[@thebeertracker.jaybeertrac9846]

You had any problems with rear ignition coil driver and o2 sensors. Help appreciated 🤙🏻

[@santosbartolomey581]

Hey Blockhead, that’s a nice build. I can appreciate it. Looking forward to seeing your next pull figures with the throttle body & any other parts you decide to use. Good luck

[@sportsterrider2087]

Beautiful bike.

[@Dustin359]

You should've rented one of those cherry-pickers in the background for an eagle-eye shot ;)

[@sway0221]

Looks bad ass! I know u shy away from the camera, BUT I caught a glimpse of your beard...Reminds me of FlipNa's beard... 🤔🤔🤔🤔🤔🤔🤔🤔.... 😂 Lol

[@joshuaramos2839]

Just started the video and want to say I hope Chris didn’t wear his new shoes this time lmao

[@roadwarrior_21]

Dang Blockhead! Now you have me looking for an iron to build🤣

[@anthonyjohnson9539]

That bike is the OG? Yes that is so sweet n bad ass looking

[@BlockheadMoto]

Yezzir 👍🏼 thanks!

[@STHLance251]

I see a drag race in Mexico between this & the new Sportster S in ol’ Block’s future.

[@user-bo4ki2zq2m]

why do you bring up such a ratty show in the middle of a perfect review.

[@billcobb9408]

I ran the same type air breather and honed it out to match the gasket hole. It made the same power with and with out the air breather.

[@subdu3dcha0s35]

Is it me, or does that Blockhead gold look red on camera? Lol! That bike is absolutely gorgeous! Fantastic work fellas!

[@PutMilesOnIt]

I would think you should put a chain conversion kit on it as well =)

[@robinsonsmotorcycleandauto3929]

I just noticed they have your banner up in the shop. That is pretty kick ass. I need to visit that dealer one day when I ride down there.

[@karlhockenberry9130]

[@billcobb9408]

I ran the barnett scopian clutch with the heavy duty springs. I had to do the easy pull clutch or it would have been really stiff. Aaron from Hammer knew my bike,

[@414moto]

Bike is sick! Pretty amazing how much work is necessary to make 110-120hp on an EVO. New Rev Max and Indians 1133cc make close to this with a stage 1... the future is bright

[@The412Devil]

That indian isn't putting 110 to the ground on stage one. Maybe crank.

[@henrybruening8889]

Sure is looking much GOODER !!

[@user-ex2qn4ds5v]

Love the build and the bike! Looks and sounds badass

[@harleydave2316]

Is there a way to bring up the torque? HP is great but most people don't ride in that rpm very often. Love the paint!!!

[@BlockheadMoto]

Usually cams, we’re using what Hammer provided for now

[@frankhubbardiv8711]

Definitely in favor of better suspension. Have you thought of Legends or Ohlins? Also I love the red & black.

[@TheBadnewz79]

Bro...Red BST wheels!!!💪

[@clubstyleridahd4695]

I've been waiting a long time for this ! How does it compare to you're 131 power wise?

[@Alphaaussiegaming]

I reckon it would be a totally different beast since the 131 is making basically double the trouqe of this bike and 40 odd more horsepower I reckon 131 would just be way more snappier compared to this bike I could be wrong but that’s what I think lemme know if u think the same

[@BlockheadMoto]

Since the 131 has 151hp/ 150tq, it’s much different and noticeably more powerful.

[@clubstyleridahd4695]

@@BlockheadMoto your living the gear head dream!

[@IxcharleyxI]

He should race them!

[@juliozapata5032]

the baby is so adorable...

[@Firestorm637]

110 horsepower at 7000 horsepower. That’s a lot of high revs for typically slow revving Harley’s. Riding around town at 7000 rpm on a bike not designed for 7000. When you buy a new oem bike, engine designed from ground up. Mod engines are a different. Like Some Honda cars are overbuilt and can tolerate extensive mods from previous non-performance engine. We will see how durable these mods end up. Like I said before the air cooled 911 Porsche had to switch to liquid cooling. There is a reason the new corvette 2023 Z06 had to go with DOHC(ditched pushrods) and flat plane crank to turn 9000 rpm, Ferrari high rpm.

[@patrickwmulligan2639]

like the paint!!

[@evil_musclemuscled3814]

That thing got aggressive on the dyno . It raised eye brows on a VROD

[@gr1m_reaper_284]

Aye that baby “everyone liked that”😭

[@sl4305]

Amazing numbers for a sportster! wouldn't a chain conversion for an extra 5 hp and additional torque be a no brainer also?

[@BlockheadMoto]

We’ll see 🤷🏻‍♂️

[@evergreenrides4902]

Have you put any thought into going 6 speed?

[@heyomyst82]

It needs more air? Sounds like a Trask turbo kit is in your near future! Lol

[@223remington3]

8:48 GUNS!

[@TEAMPANIC42]

Another great vid Block. Is it possible, and would it make a difference to make the clutch hydraulic? You know, make it so it's no so stiff?

[@brockclouser1500]

Just throw an easy pull lever on it. Running the extra plate kit and heavier spring plate on my 06… was super heavy until I got the lever now it’s light light

[@BlockheadMoto]

Not a fan of hydraulic. Will prob try out the easy pull! 😊

[@christianmarcos3906]

6:52 Why does the engine emits this "tec-tec-tec" sound? I'm asking because I have a 883r 2012 and it makes the same annoying sound. A mechanic told me it could be a simpler problem on my tappets, is he right?
