DUEL CARBS Honda 50 Dio Race Engine

[oldboatclub]

Dude,

You really need to take those carbs off & get them out of the way - Saw off the manifold and run a 1/2" fuel line straight to the transfer port - Then Nitromethane in it - it should make at least 3 horsepower.

[DIOSpeedDemon]

@oldboatclub I really like my idea better. With a slight modification and tuning of both carbs, the Intake velocity is doubled times the throat length, That is the key...

[TOGSTAK]

id rather prefer a shorter manifold

[Rexmaniac]

I showed this video to a mechanic friend of mine last week, I don't know what he thinks because he hasn't stopped laughing at the stupidity of it.

[YAMR1M]

So funny... I almost spat my drink all over the laptop! Would love to see how many have tried this thinking it would work!!! Would love to see you do the same and fit multiple power bands too! Hahahahah......... 

[DIOSpeedDemon]

@YAMR1M I am glad you liked it. I should have my own show on Cable.

[Rexmaniac]

Please weld your toolbox shut........

[randolphmarshall]

Well, I prefer the dual carb method much more tha the duel. Why have them fighing each other when they could be working together. Also a demonstration of theengine actually running in this configuration would be mor convincing tha all of the hyped up text and tech mumbo-jumbo. While I was out walking around on worshiped holy water a it occured to me that dual engines would provid a much greater boost in performance. If you know what I mean.

[TheMcFrench]

ozzy kicks ass

[trustinrust]

For hell! Sometimes a massive + on horsepower is so simpel... whats about 4 or 5 carbs inline? That must be impressive.....

[DIOSpeedDemon]

@trustinrust GREAT IDEA! I was going to stop at THREE, but now I dont know.........

[The12Nurse]

top speed?

[drktm260]

how can i put 2 carb on my honda dio please?? what do i need and where i can buy it?? please

[nikhilphillips]

This is by far one of your most informative videos! Thank you RH DSD!

[DIOSpeedDemon]

@nikhilphillips It is my favorite video to be honest.

[russ13b]

I honestly don't know where to start with this. So i'm not going to.

[Mago10993]

You should take the slide out of the first carb, the one closest to the reeds

[mikelovesbass09]

trick man trick looks siriously sick do you have any video`s on air to fuel ratio changing ther is to many to look through all of it cheers man good vid i`m loving the music man good choice

[cobraking68]

Intresting , but why not just use a regular supercharger to force more air In then convert it over to fuel injection!

I'm looking at tuning up my "83" Honda nh80 lead (aero "us") so I will keep watching!

And anybody who disrespects anyone who likes creative thinking and black sabbath or ozzy should be shut up for good !

[DIOSpeedDemon]

@cobraking68 Supercharging will not work on a reed valve set up. Only true valve engines can be supercharged above atmospheric conditions

[MJD595]

Don't listen to the bench racers, but change "duel" to dual. It makes it sound like the carbs are fighting each other. Have you experimented with reducing the crankcase volume or raising the transfer ports? Just curious.

[jamesandrew2000]

Does it run ?!

[assoonaspossible12]

start it lol..........

[heatherandpaul2]

You are joking right? How much money do you make per subscriber? Are you somekind of Youtube movie star? HAHAAH. You define yourself by how many subscribers you have? You are sad.

[GREVS2]

@heatherandpaul2 your moms a slut.

[heatherandpaul2]

At least she doesnt ride a faggot ass scooter pervert boy.

[GREVS2]

@heatherandpaul2 good so you agree she is a Slut.

[heatherandpaul2]

Yes you are correct. Scooter boy

[heatherandpaul2]

How cute. Yeah, play Ozzie real loud in the background. It makes you look tough. It hides that fact that you are tricking out a........MOPED.

[DIOSpeedDemon]

It is a RACING MOPED, son. You better Step UP or Step OFF... I like Ozzie and so do the 200,000 viewers.

[heatherandpaul2]

Oh, "racing" my bad. Now that you mentioned that it was a racing moped, it makes it not gay. right.

[DIOSpeedDemon]

Lets see your videos, friend, OF COURSE you dont have any. I have 1000 subscribers, how many you GOT??? None of course. Make some videos instead of opening your mouth with cheap talk. My racing machines will smoke anything you have. Son.

[2889joeracer]

do you have any videos of the engine before and after these mods?

[DIOSpeedDemon]

You need to read the description of this great experiment, That is .....IF YOU CAN READ ANYTHING NOT WRITTEN IN CRAYON. You will need a dictionary. WaxHEAD tells me all I need to know about you son. RH DSD

[DIOSpeedDemon]

THat is what they told the Wright Brothers before they first flew, SON. RH DSD

[jetskiwaxhead]

What an insult to the wright brothers to even put this mistake on the same page in text

They would turn in there grave if they realised that you said that

[94jettameowpsst]

this is why rally cars that have a 38mm restrictor have 300 whp and 500 ft/lbs of torque.....it adds power with the smaller intake path.

[transmissionjimmy69]

did you get the idea from your dual carb'd bong?

[2SliK3]

ин ах 2 карба? чё там за поршня то? не меньше 150кубов тогда, а такую куй найдешь, самая большая 120 кубов, на нее 30 дырки хватит, ну побольше чуть...

[clementwn]

stupid. wasting gas still sucks a little air only....guys if your want to see what is power gi search on malaysia 125z open you will know what is power

[paoktshsostokokalo]

here in greece we tune Z too :D we convert em to water cooled and much more bores from WR

[scooternosmodox]

Oh,what is this fucking thing?

It's horrible,but expecially whithout any sense xD

[poliniEVOLUTION2rox]

i dont think its gonna run smooth if you need more gas install a bigger flatslide carburator with powerjet system it will work alot better.

[13000rpm342]

dude its a scooter. y wold you dump cash into it

[mrmardy]

Right on man cant wait to try this on my R1 . Why havent yamaha thought of this? You have such a fertile imagination man. Is that because you have shit for brains?

No seriously it looks great and lots of fun. But does it actualy even run? Keep on banging those rocks together guys..

[NehpetsK57]

how does a dual carb work again?

[InnerFrei]

This work hasn't got sense.

[kragstips]

wait.. that really doesn't make very much sense. at all

[DIOSpeedDemon]

@kragstips All great inventions are scorned at first, then accepted as genius. If we dont push the envelope we will not learn to progress.

[aorider86]

its a 50,............relaxxxx

[anonimo90alex]

aaaaaaahuahuahauhauahuahauhauh­auhauahauhauhau pig

[lotuselanplus2s]

WASTE OF TIME !!!!!. You wont get any more airflow that the 28 mm will give and having the slide and needle from the 30mm in the airflow will only make matters worse,stick with the 28 and velocity stack,by the way if the carb is too big and it would be if your engine is 50 cc you would get loads of tuning problems,like low velocity,try a smaller carb,try 20mm ,you might even need to go smaller than that.

[anonimo90alex]

omg...stupid guys...

[deroldzzzzz]

even if you install ten carbs if your engine cant burn all the gass inside your engine, its useless, sorry for that

[hohoemm]

Imba mate THX <3<3

[tm400sm]

it is orrible!

[CastuBooster4ever]

chissa xk non l'ha acceso...sicuramente nn parte neanche...

[tpvalley]

This is stupid and extra carb will restric the airflow!

If u want more fuel fit bigger jets, if u want a higher velocity fit smaller carb of inlet trumpet, u will only flow as much as the maximum flow of the smallest carb, in fact less than.

volumetric efficiency is what ur aiming for, this is the efficiency of the engine to pump air, u need as biger carb as possible for max VE.

[aimlessanduseless]

The chrome wheels and the water injection.

Water injection makes a denser charge to simulate higher compression, as well as cools and cleans the cylinder walls but runs real lean, so water cool it so you do not nuke it, dude.

[dylanleewise]

Why stop at two???? maybe 3 carbs will be bettter!!!!

[auto4union]

Great stuff mate !! Love the vids !! Good to see the spirit of the "Back Street Heroes" is alive !!

[sirlordwest]

cool concept if you like to wast time.

[syntroxis]

LOL, are the carbs going to pick up foils and fight it out?? I'm sure It's "DUAL" carbs.

[Heiza06]

sinnlos^^

[boybangungot]

is that what u call racing engine? what is that for? my yamaha jog nextzone so cc can beat that twin carb...

[chargersublime]

You have got to be kidding me.

Have you ever jetted anything on you own or does the dealer do it for you!!

[andysquirrell]

no no no no no. computer modelling?? this is not scientific. the huge fuel filter will help? no. dude dream on, shame on you fool.

[ratheads]

"This will give a supercharged effect"

AAHHHHH HAAAAAAA HAAAAA HAAA ! !

[ratheads]

DUEL - what a moron.

[slide4squad]

lol

[scootertronics]

At least you got every idiot to look at it.

[LLLosingit]

Ha Ha Ha what an idiot, I really hope your smarter enoguh to have put this video on here as a joke!

If not you need to put down the tools and pick up a few books.

[TheOx1989]

si vede che fuori dall italia la gente non capisce un cazzo..non ha senso la modifica??diventate matti a carburare quella merda! comprati una aprilia rs.. stupid ..translate pease..e se ho scritto male pazienza

[Vatherland]

cool looks greath. why not a supercharge blower from the out gas, plus a oxagin assite.?

[jetskiwaxhead]

I was looking through your videos then saw this one and it was clear

you actually know nothing about how a carb works

It will flow the same amount as the most restrictive carb

What the heck were you trying to achieve

If you want more fuel them put in larger jets

[DIOSpeedDemon]

I have received amazing results with my little experiment. The carbs look ordinary on the outside but are completely modified on the antier/interior tract flow pattern.

[jetskiwaxhead]

yeah right bud

you have just identifed your self as an idiot

I suggest you read up on how carbs work

[lotuselanplus2s]

Maybe the dual set up is lowering the velocity to the point where you flow like a smaller carb,,increasing torque,just put a smaller carb on and jet it correctly.

[saintluke87]

All i can think of, is that if this idea worked, you would have seen it somewhere in motorsport before....

[tpvalley]

Please take this stupid video off.

The smaller carb will reduce flow, so ur peak flow will be no better than peak of smallest carb.

Having 2 throttle slides simply has more restriction, having 2 sets of jets will just make it richer, once u jet both correctly whats the point?

U just have basicall a carn with 2 slides and more intake restrition.

Why do u think they make smooth bore carbs?

Volumetric efficiency is proportional to port timing etc and intake resistance!

stupid video.

[fabianromano]

They are small plastic ducted fans/turbines that work on a rechargeable battery, and they are really powerful, so I guess that would force the air trough the carb into the cylinder, like supercharging the engine, I'm sure it'll work and is pretty simple. You could put a switch on your handelbars to turn it on like a turbo.

[fabianromano]

Hey, I'll give you an idea I had for a time but never tried, you might try it. I always thought of putting an RC airplane electric ducted fan between the carb and the air filter..

[rustyATV]

You're only increasing the velocity of the intake. Supercharging and turbocharging increase density.

Also, there's a general rule that your intake tract size should deviate no more than 10%

[jaysus200]

hmm... that makes no sense. sory dude, you seem to have the wrong idea. if you put the two carbs in line and sychronize them, you in theory COULD make it run, but it would probly be slower than stock! what you need is a small carb with a HUGE mega phone to improve draft, or, a really really big carb but with the bore sperated into an upper and lower segment by a blade. this would remove the bog of a large carb on part throttle but still give ax draft at full throttle. eh, kinda got off point!

[jasonmccoll]

I agree! All that is happening is the air fuel mixture is being mixed up by two carbs and will end up being a jetting and adjustment nightmare!He should just stuff a chromed yz80 engine in it and have the fastest fifty kinda in town!

[Terminchiator]

never heard about that......

vespas got the twin carb kit but for twin intake system (cylinder and crankcase) i think you are only creating duct size variations causing a loss of speed and ram effect

[bassmechanic71]

how perhaps?

[stoker20]

That's very funny. You're very brave to put your invention on the web. Someone might steal your designs! Are you looking for investors??

[aaron9696024]

LOL.... go home.

[dlrmoto]

why!!why would you bother, and you have the internet to do reaserch and you come up with that idea!!, it wouldn,t work if jesus himself did it!!

[STFUandTAKEyourMEDS]

dude- youve got wayyy too much time on your hands.

nice scoots though.

[krzysiekv12]

whats the point ?

[flobeul]

big shit ..

[naake1]

IDIOT !

[lambrettist2007]

Post dyno printouts or 1/4 mile timeslips please. Err, supercharged effect would mean that the air to the carburetor is pressurized above atmospheric pressure. Please explain how you think this is so.

[wolts77]

Super charged effect my arse lol. Take your hand off it mate.

[gilessmokey]

leave the spanners alone! you are making a mess.

[Patrickisafish]

"this will give a supercharged effect"

i laughed hard at that. for all of you that think this will work well, you have a very poor understanding of how a carburetor works. the first carburetor (28mm) will determine the flow; the second will do nothing but create turbulence, add restriction, and dump too much fuel into the intake. get a wideband o2 sensor and tune one carburetor, and do it the right way.

duals can work, but your doing it wrong. bigger is not always better, keep that in mind too.

[cdoublejj]

i'v seen it done right with a Tecumseh once, the intake was custom made it had the carbs side by side.

[Patrickisafish]

yeah, side by side.  my car has 3 carburetors, but this is retarded.

[deizt08]

god damn it...lend me that bike..i wanna try..!!!

[concretedreadlocks]

that bike needs to go in an ozzy osbourne video

[rolbk27]

genius? dont think so...the 1st carb has no gas cable...how dies it work?....hahaha....ulol!!!!

[twilightnekochan]

WOW. That is genius.

[SpencersGarage]

do you split the fuel lines? to goto each carb?

[GeorgeR34]

Ozzy 4 EVER!!

[wolffy2008]

This is crazy! Keep it up.

[kwijaeboner]

fucking genius. Thats some great work.

[DIOSpeedDemon]

Thanks Bro, check out my other 280 Dio videos. RH DSD

[XxMurdersitoxX]

u are crazy man, this is amazing

[rickika]

how do you convert those two carbs?

[LockHoodlum]

Fucking insane carbs!!!!!!!

[D1rec7or]

sweet

[ivorbigun]

You might as well rejet the first carb,it would have same effect! Less expense!

[DIOSpeedDemon]

Good idea friend. I will try that. Thanks DSD

[bitoypower]

you comment on ur own video? r u dumb...

[therockeronner]

lots and lots of people do that dumbass. he replied to someone elses comment.

[ms51ves3]

Re-jetting a carb only changes the mixture. If you put a larger jet into a standard carb it will be running too rich and bog down making the bike slower. If you want to increase fuel flow into an engine you also have to increase the air flow by getting a bigger carb like the maker of the video has done.

[jr4oko]

this is a joke, right?

[daedalx]

Improve your gas mileage?

[ev0l15]

lck of air.. the mixture of air!!!!

[zgyhockey]

What opens the front slide? I only see a throttle cable going to the rear carb.

[samcotterellrules]

so does it actually work???

[ringkingpin]

this is a joke, right?

[pauloscooby]

most ridiculous stuff ive seen in a while..

[Frostman182]

The thought that putting two carbs in series breates a "supercharged" effect is ridiculous. I highly doubt you will see gains in this project. I further bet to say you will loose power to a now more restrictive intake track AND too much fuel!

[simplefreak37]

wtf?? its still the same...u rather ride on the 30mm alone...so what is ur point with the 28 feeding the 30mm?

[1skiinIan]

yeah

if you want to get more power you will have to force more air in. the carb can supply the gas but it does not supply air

[kugmokigwa]

wtf!!dual??single still coz its in one direction idiot....side by side should have been the setup...ur nuts!!!

[DIOSpeedDemon]

It works perfectly. Japanese engineers have nothing on me...

[humantestdummy]

ozzy

[Niggamortizz]

Реальное гавно!

This is the real bull shit!!

[DIOSpeedDemon]

MALINKA PESUYNA RUSSKYA SOOKA...

[harrygila]

yeah mate, good luck with that.

[dawhiteboy165]

yo when we gonna see da on ???

[boo66]

Carbs in series? That's surely ridiculous!

[mastazeuj]

pur0 lang kay0 dem0 wala namanyan magandang resulta

[enemedes]

hahaha paandarin nyo para malaman

[mlatour911]

Side by side progressive dual carbs, small primary / larger secondary *MIGHT* give you a bit wider powerband but never a set-up like this.

Too much restriction and screwed up vacuum signal. Put it on a dyno and show us the before & after results.

[masterSync152]

putang ina....kala nyo maloloko nyo mga tao.. mga ulul!!! hindi kaya ng dio and duel carb.. pina andar nyo sana para maniwala kami mga bitch!!!!!!!!!!

[falcon8r]

To a given displacement ,only an A/F ratio of around 14:1 will run that engine. More gas means more slow! If you used nitromethane as fuel ,then perhaps you could use all that gas on 50cc...and what? 10 h.p.? Check that bsfe!

[DIOSpeedDemon]

That is an excellent point falcon. I will check that bsfe, and do some more tests. Thanks! RH

[tottigol123]

This scooter with double carbs can't work,

If you post a video with engine started you are a genius!!!

[wouldntrecognize]

yang dong fong

[TheFartenator]

The second carb will "supercharge the first"? I doubt that it will make much difference at all.

[cCcKaan52cCc]

omg..

[lazzer408]

totally useless.

[tangnamogago58]

can u post a vid doin 10mph on ur stupid mc.

[DIOSpeedDemon]

SURE, NO PROBLEM MAN.

[par11par]

cool!!

[michaelwoodcock]

by varying the slide position between the two carburetors, you are able to cover lean spots without re-jetting, and thus a perfectly tuned scooter without constant tuning,

oh, dood, do a search on the veypor, it calculates horsepower very accurately, and sits on your motorcycle

[DIOSpeedDemon]

That is a great idea mike. Varying slide position was one thing I did not think about. I will test the slides and look into veypor. Thanks!

[tpvalley]

The 2nd carb will simply restrict air flow to the first, the smallest carb of 20mm makes the 2nd pointless.

This is a joke right?

If u had the carbs in paralell it would work like a twin choke.

It is to do with cross sectional area of the carb venturi, this is the right size to acheive given air speed.

[blackmoon888]

Your design is plain STUPID! & BS!

[hokuleleboy]

brah it wont work and mabyuenot u stupid its a dio motor ass wipe das how much u know about bike huh it only has 1 cylinder.

[meatwheelie1]

dio, are you a colossal idiot??

[coltron9008]

with the way the carburators are setr up its gettin no more air with one then two air is needed more than fuel the stokio metric ratio is 14 pounds of air to one pound of fules air is need more than fuel so tho carbs attached isnt giving anymore air none the less restricing it

[DIOSpeedDemon]

I run a Kioko Nanji counter balanced and finned race variator. I have no way of assessing the BHP. Getting the motor to run thru the entire power band smoothly, is all I am interested in now. If I had a motor cycle power tester to test bhp, then I would know. There is nothing like that in my small town.

[D022Y]

Mucha hablada, no demostracion!! men you suck!!

[scarfacefan4eva]

I wanna see it run..................

," This Carburetion Theory has been successfully used on the 1932 Sterling "Silver Bullet" motorcycle."

what i like race boo ship your bike down i like sample your theory brah your bikes is doodoo i seen you build the stroker how come you no port your shit

[hokuleleboy]

ur so mento ur retarted, how r u gonna open the slides at the same time?

[peaseyboi]

dumbass!! how du u think they do it on normal road bikes with more than 1 carb? use that thing between ur ears u muppet!

[mabyenot]

peaseyboi why dont you use your brain? an typical carb sportbike would have 4 carbs yeah? guess what, 4 CYlINDERS RETARD

[peaseyboi]

oi, i was answering the otha guys question on how do they open at the same time, and i am WELL AWARE THAT ROAD BIKES HAVE FOUR BLOODY CYLINDERS!!!!! i'v bin workin on bikes most of my god given bloddy life, nd it just so happens a kno a lil bit bout em, so dnt treat me like some fucking idiot!!!!
