Home-made V8 motorcycle

[bpastorb]

doesn't look very comfortable

[Mokhas45]

Nice attempt but I have my doubts about the frame supporting all that mass.

[flugelrad1]

agresif

[DucatiSayWhat]

But will it blend?

[brandonbullock50]

that thing F***ING AMAZING!!!!

[cacneaunit6]

TROLOLOLOLOL!

[paul39man39yo]

whoooho!!

[joneilertsen]

okay... i imagined like.. a cardboard bike looking thingy...

[falaqdad15]

That is a sound you won't be hearing from honda anytime soon!

[iuli902]

good job man!! that's a nice sound ;)

[DeNicoPeeke]

Mooi gemaakt jongens!

[MrAsh134]

cr 85 wuld tan it !

[bigrobnz]

Amazing work!!!!

[oldschoolmotorsickle]

That thing barely runs; won't idle, has a massive exhaust leak, terrible

[TommasoCompiani]

wow, amazing!

[jacktheripped]

SESCO made a midget race motor like this. Mel Kenyon used to run one.

[kwack23]

if he changes the firing order then it will sound like a v8 not 2 straight fours.well done tho.

[TheHanndave]

@kwack23

Google-flat plane crank

[craveman85]

i like it. sounds like my 84 interceptor.

[crazyfvck]

That's a very nice piece of work, and quite a unique sound :)

[Blacklamass]

Why ?

[crazyfvck]

@Blacklamass Because he can, that's why. People have been doing V8 motorcycles for a long time now. I've even seen a few with small block Ford and Chevy engines in them..

[warmfreeze]

amazing creation. grats.

[LaurencioVieira]

I would love to ride that thing!

[angelb650650]

sounds wery bad!

like 2 cylinder engine

[MrJawesome1]

street legal?

[pencon61]

wicked - sounds awesome and I like the styling tank etc

[pencon61]

wicked

[funonwheelsbynaoki]

i ca tell the frame is a "modified" Moto guzzi..also all the rear end ,swing arm ,gear box,wheel ....

it is a very nice job anyway .

[carlosr428]

yo This is AWESOME!! takes lots of work and thinking to engineer something like this, mad props bro! wouldve been cool to see it done on a car tho, i would love to see a honda V8

[parkermartin161]

That must be the smallest v8 in history at 800cc. I hope you post a video of it in action soon.

[purpleGoAhead]

@parkermartin161 not really... moto guzzi had a famous racebike in the mid-50's which used a 500cc V8 ;)

and don't forget about all the model-engine builders... lot of them build V8's with dry-sump lubrication, watercooling, spark-ignition, OHC etc. just like the big ones :)

still, this bike is just stunning - i always love to see people creating things straight out of their mind :)

[haros540air]

wow 2 guys in a shed with some free time and you got something cooler then half the shit on youtube

[jjjjcuervo]

Very clean, very cool. Wondering how well that skinny tire is gonna do against that motor. Please post a video of the drive if you can.

[mevanz]

great job! There's a few guys on here with tips that may or may not be worth putting into play. I know it isn't really intended fo performance as much as the journey of building it, but let's see a video of it in action anyway. Pretty Please.

[procycleservice]

Sure would run better if you built 2 air box's for those CV carborators with a cross over tube to equal out the flow on the intake.

[xXxDANMANxXx]

omg that thing is NUTS!!!

[HecticAussie]

I like it ! Great job guys.

[zeeadkar]

fly with it

[robiniroven]

i want to see it drive and rip off that tiny rear wheel lol

[NLstb]

4 bugi's, das nie niks

[austpom333]

Het toet et

[songsamsung]

An Australian named Ken Drysdale built an 800cc V8 sportsbike back in the '90s. It used 2 Yam 400 top ends on his own crankcase and the engine was plenty narrow enough to be mounted transversely so there was no torque reaction. I have no idea what became of the bike.

[inagod]

@songsamsung have you seen the V12 Honda ,built by some guy out of his one car garage,what a sound.There is a V8 Kawasaki too,some guy built it.

[xXCREEKSTARXx]

God this thing is fuckin sick :D

respect man.-..im happy if i get anything like this or a car that great and selfmade later....

[cobra660]

That looks awsome i want to dosomething like that but withaford 5.0 :D

[jerrysjunk]

wow he did a great job .cant imaging the time it took just for the engin .

[veoibm]

Now this has to be the best lookig V8 bike I've seen. Great job!! The motor looks like it belongs on the bike.

[Bravo21]

Sounds like a flat plane crank. I understand WHy you did it, but a cross plane on a V8 would have given better sound and performance I think.

[2jzgtejza80]

@Bravo21

Sound depends, performance not.

Great project.

[Hetman1974]

Respect!

[glazerguy58]

Sounds like it's missing.  Sounds terrible!

[Pantostadoh]

how much consume that machine? nice big bike!

[havoc1316]

Its a work of Art

[Rabelius]

what kind of v8 is that it seems to be werry flat?

[janders1957]

Oh man, this makes me dream of retirement so I can start playing in my shop instead of working... A very very nice piece of engineering and craftsmanship!

[TheMTFUJI3776]

凄い！

[505197]

Wow, beautiful piece of work and design, it dosen't sound very pretty in this video though. Sounds like it needs some sorting out, must have a flat plane crank and be fireing 2 cylinders at once. Mel Kenyon built a similar engine to run in midgets in the US. It was a beauty but didn't really pan out for him. He'd intended it for long tracks like Salem where the thing might enjoy an advantage in high end power, but I believe he just gave up too many CCs to the established engines.

[rentatrip1]

pity the fool who must sync all 8 carbs-

when Honda manufactured their stright six motorcycle the primary flaw with the design was not being able to syncronize all six carborators and thus the performance of the six cyclinder mmotocycle suffered due to an inability to match output of all six breathers - But you all have made a remarkable attempt at an elaborate two wheeled machine - very nicely done BRAVO

[gilessmokey]

@rentatrip1 japs have no trouble balancing four cyls, so if you can do four you can do six.

[bullydogRJ]

it is great that you can do that.I would just tack the easy way out and use a small block 289 or somthing

[speedemon103]

Dam man, put some real tires on that thing and u got 1 monster there

Very good work, props to u....now let's see what it can do on the street ;)

[olepeterbilt]

That took some amazing machine work....nice job

[44750682]

wow, super awesome job done!

[albertonex19]

Give that man a coke!

[fasteddy350]

awesome job and a sweet bike

[MrICE003]

PROPS to YOU!!!!

ART in perfection!

[Chijousaikyo]

Brilliant!!!!!

[ps10iceman]

this is awesome,it still sounds like a honda!!!!

[sunn1e]

that would confuse some people at the lights

[scott93257]

definitely going to give credit where it's due...This man has built a masterpiece...

[stevibhoy1]

Scorching soundtrack

[Dualshock21]

i must say that looks pretty awesome

[NASTYTHEBOY]

fuck some shit up :)

[bahienseFord]

CC ?

[Shazee083]

wow cool bike that alot of skills so what you do for a living or what type of skills you have more practical or logical

[phartnokr]

How fast? 200mph? I wouldnt think that some one would go too all this trouble and not put it to the test. I know I couldnt.

[slurp812]

Needs a bit bigger back tire...

[royalbrainwave]

Needs a bit of tuning aye?

[barneyboscoe]

sir,i should like to shake you by the hand.wonderful.

[rcbasher101]

HP?

[0348511]

thats fuckin badass!!!

[gino800]

like the bike but that engines beggin for a badass go kart/sandrail thingy

[vfr750jap]

I would LOVE to own this bike. You guys did a splendid job.

[honeybunchickens]

I love that sound

[Scootertuner1000]

Mates, that is 'ucking awesome.

[dkosto1989]

man that's just crazy :D I would love to see and hear that beast :D gr8 job boys. keep up the good work ;)

[juice0791]

ok it very cool I will say but if he cant afford a real one beccause they are to expensive how did he afford to have a custom made crank case like that made that surely wasnt cheap

[vandos11]

how is it cooled

[memmnock]

sweet man

[TheMrfrawg]

much respect very nice ride

peace

[Boggle122333]

guys it sounds like a V2 cuz the cams and valve timing is different from a regular V8 in a car

[Boggle122333]

guys it sounds like a V2 cuz the cam timing is different from a regular V8 from a car.

[inagod]

beautiful job,good luck,did you sort out the motor or is it me?it just sounded a little off.Again thanks for the post,any updates,have you driven it?

[CJBroesky]

I am looking at building a motorcycle with an inline 6 5.9L 12Valve cummins diesel. I'm having a problem looking for a transmission to use.

[peterfarrow]

@egpg2000

I don't thinks so, not with those pram wheels, and as with all bikes, it WONT go round corners and /newsflash/ we don't live in Rome...

[9ssdv8r]

/watch?v=KGitMKhUdHM

And yes, timing was a bit off on first starting attempt,so whats all the fuzz?

Next project; 300kph+ streetlegal sidecarbike,and Ferrari racing engine in trike!

[9ssdv8r]

2 Honda 400RR enginges bolted on a custom made crankcase.

Frame is also custom made.

Rear tire is intended to be slim for being old school racelooks.

Bike is not build as much as for driving as for the experience of being able to build and own it. For as only Morbidelli makes expencive V8 bikes, he stood up to the challenge of building his own.

The guy just loves the sound of it.

2years of construction 3000hrs.Show the man some respect!

[corotor12345]

@9ssdv8r

Two years? Oh, but what took him so long? I want to build my own bike, a one off custom, and I'm scared to not finish building it in under 8 months.

[1980kevinpaul]

@9ssdv8r He could have just flushed the money down the toilet.

[Moleydoc]

a mi juicio las los neumáticos son algo pequeños para la potencia de esta invención

[pnbliveca]

it sounds like shit

[XxmonstahobgobxX]

you probably can only go in first gear unless you want to die

[IamPUREEEE]

You need to put that thing on a Dyno and see what it'll do :)

[Schizy01]

A static display for audio qualities? What kind of drive train / clutch / transmission is there NO ROOM FOR?

[purpleGoAhead]

this bike looks and sounds just ASTONISHING! it's great to see people building their dreams ;)

[fakkerteevee]

insaine in the brain

[jordyboy0129]

you need a bigger rear tyre

[absolutholland]

grande!

[Maximusfool]

its 2 inline 400 cc engines built together, mated to a Moto Guzzi gearbox. It makes around 120 BHP at about 10 000 rpm.

[joshfontanella]

i dont know much about v8 bikes but surley the rear tyre cant take all of that power

[Maximusfool]

@joshfontanella The engine sin't that powerful 90bhp at the most. As the description says he could afford a Morbidelli V8 so he built his own. Back in the old days when bike builders were still buiilding v6, v8 six cyclinder and 5 cylinder engines, then that was tho only sort of tyres thye had. The huge tyres we see on modern day bikes have only been around a short while. You only have to go back to the late '80's and see how thin the tyres were then

[carl2017]

Amazing engineering. Something to be proud of.

[terrenkyl7]

you fools are such critical clowns, cant appreciate anything what have you built in your pathetic lives!

[newgroundsTVnet]

bent u nederlands want ik ben nogal geintreseert in da gedoe met motoern

[localdu]

another question, what is the displacement?

[meattube4u33]

whats your rod length stroke ratio?

[meattube4u33]

first off congrats for making the effort, btw you have a leak up front, now about that back tire. . . you are gonna use a much wider tire right??? and about the tune/timeing your gonna work that out as well right?? it sounds really off

[localdu]

how do you keep the engine cool?

[Dezerado]

um.... no radiator? ... will Air cool a V8? .... i mean it just seems like you'd have to be running 100mph all the time just to keep it from locking up

[pokesmot831]

You fools are smokin a Metric Shit ton of methanphetamine 

[joef595]

glady, I did not build my Valkyrie, Honda did. These guys also did not build the engines they are using either. As you said, they just joined them together. Big deal. Its not rocket science. And yes its in the tuning. Again this is not rocket science. Looking at the video they have to get the timing right ( from the pulse generator ) and the exchausts have to be sorted.

PS I am not a rocket scientist.

[terrunazz]

sounds like a v3...

i think yoo guys gave to much stroke to the pistons...you need to build it with shorter conrods...

[rockyny1]

pretty damn cool

[joef595]

It does not rev well, it does not tick over well, and well, it sounds shite! They need to do a lot more work. My Honda Valkyrie with six into six exhaust sounds ten times better and I can actully ride it!

[glady91]

@joef595 but you did not built your valkyrie...show some respect for this guy who joined 2 engines together and made it run...eventualy it will run like a charm...it is all in the tuning of the engine.

[schlusselmensch]

Are those racing ViseGrips?

[motokrack]

@schlusselmensch lol 

[elricdean]

lol the exhaust is to short it shoots fire

[philtripe]

sounds very capable and beastly but not a pretty sound,ugly even...motor needs to be in something equally ugly and mean , like a tank or something with a gun or whirling blades on it... chop chop i need whirling blades on that bike and ill approve

[timbob974]

it's amaaaaaazing

[bitcunth]

what PSI do you have those tires in order to carry all that weight?

[zwierzok]

Beautiful, classic bike mate:)

[paintslinger2009]

pppppppppppuuuuuuuuuuuuuuuuurr­rrrrrrrrrrrrrrrrrrrr

[platinum014]

that is obviously two motorcycle engines held together by one custom made crankcase. the sound is because of the very small c.i and and the firing order. looks like alot of costum machined parts. no offence to the creater of the bike but couldnt u just went out and bought a small c.i v8 ( like a lexus or triumph). alot of there v8s are around 200 c.i. then did a cam swap for higher rpm's. but thats just me.

[jmorgan118]

@platinum014 Lexus V8's do have a somewhat small displacement but the external dimensions are nowhere near small enough to fit on a bike this size. Btw the 1uzfe is 3968 c.c. or 242 c.i.

[platinum014]

@jmorgan118 true

[choopdewoot]

amazing sound. i would love to see that in a touring bike. i wonder if he can get his knee down with that

[vibeflyer]

Twin Shock 70's style

[gubbadog]

Why don't all you experts back your mouths up with your own V8 bikes? Then you opinion may be wouth something.

[deannaber]

Its cool and the effort great!! i like the rear tire and old style shocks ...

[mowat440]

is at a ford flat V-8 from the 1950 and 1960

[amfan12]

@mowat440 That is not a Ford Flathead. It looks to be two 4 cylinder engines mated together.

[Maximusfool]

@amfan12 heads and cylinders are from a Suzuki Hyabusa. I'll find a link to the iste and post it.

[betterthanbrad]

He probably has 2 cyl's firing at once!

[nate338]

Could it be that he is running a flat-plane crank? That would space out the exhaust pulses and give that angry 4 cylinder sound.

[baggens55]

seems a bit excessive 

[fuglyucker2468]

yeah, that things not running on all 8

[carsnwomen91]

rear tire is the size of one off of a CBR125R

[counter37]

0 grondspeling

[TheMTFUJI3776]

素晴らしい。

[honda900fz]

yep its run ning on 4cyl lol my mate built one of these 20 years ago and it went like a v8 not like this shit box ahahahaha

[sxvrm]

Deze gast is vanaf nu mijn held........

[synthesizer301]

hallo mensen in een woord '' respect

[chris2010]

rear tire looks funny a little bit to small

should have 5 times his size :D

[tjmeile]

looks good sounds great\

[bassoundlikethunda]

dude ur carbs cant be vertical like that, thats why its only running on half the cylinders and sounds like shit.....

[Lovemycbx]

@bassoundlikethunda - I think the carbs are side draft which most inline four sport bikes have it they don't have FI and those are obviously new heads. If they aren't however your totally right. Not to mention that because of the intakes, Fuel air mixture would actually suck right out out at above 100 MPH because of the velocity stack positioning... but then again, Who the hell cares? that thing is Bad Ass!

[Thetruthishere11]

Would you take $100 for it?

[alansaladan]

nice work, a couple of regular surgeons

[tiecuando]

That's awesome!

[geewizboogieman]

geweldig!!!

[steveeaa]

maybe a valve tight.

[klecarner]

cool , but good luck cornering

[the5445]

doesn't sound like it is running on all of the cylinders

[cirss444]

Where is cooling system?

[Simplysick408]

horsepower? what type of block ? specs?

[indestructableforce]

Sounds cool. What are the specs on that?

[Deeman4evr]

Sounds like only 2 cylinders firing to me. WTF?

[stevepone]

Thats what I thought - didn't sound right - but nice looking.

[munteanuioan]

skini tires cant put power to the ground

[wpepie]

that guy lives a village near my village, he put 2 4 cylinder engines together, the frame and all the other stuff he made it himself. here another video:

/watch?v=KGitMKhUdHM

[discocreator76]

looks like two l4 bike engines sitting on a custom crankcase to me....

[SURTR6]

awesome, sounds terrific! \m/

[Aece2002]

Cool, but the rear tire is a joke right?

[5769JJ]

@Aece2002 Skinny tires handle better and the handling is more crisp.

[mowat440]

@Aece2002 the bake tire whould like last at full throulte for 5 or 6 mins right

[cabritorsss]

@mowat440 That's about all you can expect of that engine with no cooling....

[redghost105]

@Aece2002 low resitances.....ya its pretty fucking gay

[jordyboy0129]

@Aece2002 got 2 things FOR YOU learn how to spell and go to school

(tyre is not spelt like tire its spelt LIKE TYRE)

IF U STILL CARNT SPELL USE SPELL CHECK!!!!!!!!!!!!!!

@jordyboy0129 it's spelt like tire outside the UK
