450cc Go Kart on the track.

Spinning some laps with my yamaha yfz450 powered 2008 Paul Tracy shifter kart. It's ridiculously fast and a serious rush to drive. Camera shuts off so I didn't get the last part of the session. I wasn't wearing gloves, get over it!! Maybe the 2nd time I drove it on a sprint track. It's been years, maybe I didn't have any can't remember. No it's not sped up, you wanna race bring $

[@speedracer3967]

Excellent combination of track knowledge, and kart capability. The passes were nicely executed, and at the same time knowing when and where to pass safely when encountering lap traffic. Nice driving sir!

[@patrafferty3512]

I drove Formula Atlantic and Trans-Am for years---and am quite impressed with your driving skill. Keep it up----have fun :-)

[@danmurphy1994]

that's amazing, I wonder if I'd be fast enough to race in any pro league.. I did kart racing as a kid and I was usually the fastest. However as an adult I find myself either too broke or too clueless to know which platform would provide me with the greatest opportunity as a racer. I live in saint paul minnesota. now I'm gonna watch formula atlantic to see what the hell that must have been like.. never watched it before.. You have my utmost respect having been a pro that said! thanks for sharing Pat

[@iceangel9006]

4 stroke??? Awesome!!! Nice driving!! Also these double s on this track,beautiful!!!!

[@bob8086]

i enjoy watching you fly by the other "racers" very satisfying

[@ericbraun4652]

So nice to have a 4 stroke in a kart for so many reasons. What fun!

[@ClipSwitchFlashlights]

Well driven sir. That thing is mighty quick.

[@Dinkymod]

That fucking go kart is fucking fast.

[@Racepilot_jessy]

Can u imagine there are 600cc? Even 150cc more than this one

[@mmtruthseeker5263]

Ridiculous! Torque is well suited for a Cart! Bravo!

[@PernicekMotorsport_]

Man, sounds beautiful! Awesome run!

[@oliverandrew626]

this kart has a yfz450 engine, and sick driving. i have a dd2 rotax

[@suavehouse5150]

dirtbike mania Miss my dd2 push start button, no clutch, with a reverse that's winning! Lol

[@oliverandrew626]

David P12 there so fast!!! but it goes through so much tyres!!

[@clarkracing6514]

the dd2 on a small track is awesome I have one and a Kz2 + a R3 shifter kart but the dd2 is so much quicker around a small track great kart.

[@joy6086]

The cart is fast, but you just having fun. thx for posting.

[@deadpool_evil6021]

i cant stop watching this vidieo keep it man

[@427Cabriolet]

I Like how while most go kart in the track is 50cc,65cc,85cc,125cc 2 stroke engine This man come up with 450cc that almost make 50hp

[@Dariuskhashabi]

They were all 125's. My buddy just built one that makes over 50hp. I should build my 450 kart motor

[@harrypeterson9287]

Some 450s nowadays are making over 60hp!

[@ZeldaACFan17]

A 450cc 4-stroke Shifter kart? Nice!

[@chefgiovanni]

Awesome driving. You got big nuts.

[@christiansantiago3007]

Looks like a grin producer. Hell of a machine.

[@johnnymiller1868]

i must compliment, this person clearly has a hell of a driving line, but what i found that impressed me more than anything - the fact that this person had so many chances, to where he could have gone for it , but it would have really caused alot of drama on the track (running off other races off the track and into the dirt or even worse... the wall! it but that means bumpin the inside races out or spining your own self out by being selfish and stupid , greedy and all three of those things dont apply to this guy. had just about the fastest car on the track and just passed by everyone with a smile, leaving em with a surprised look . i would like to know how big the very last packs engines were. they were pretty good , even with their slower karts

[@Dariuskhashabi]

Johnny Miller thanks Johnny. If it was a race I would have for sure passed them way before that. Kart racing is very aggressive. I raced for a couple years, they bump the shit out of you!

[@2K8Si]

Agreed. Great driving line, nice linear steering (no frantic back and forth corrections), and MANY times hanging out the rear end with no drama. All while showing some respectful restraint. He only went to pass when it was clearly safe. This guy has obviously spent some time on a race track. Awesome video!! Make MORE with this kart!

[@alexberriman4302]

from the glimpses at the valve cover my guess is that that was a Yamaha wr or yz 450 motor that had been squeezed into that cart frame, sweet power to weight ratio!

[@raudib6737]

Alex Berriman aren't you smart only says it in the description

[@mxer4life]

Tyler Abell some people don't check the description. Hell I forget there even is one because I never open it up to read it lol

[@DR-br5gb]

must have been those super sweet sunglasses that helped you spot that!

[@kennethfarquhar8518]

Always the losers with nothing going for them selves with the most to say 😂. Just remember you bunch of 🤡s .. “ for every finger you point there is three pointing back “.

[@flyinghorsepolowski4205]

Holy shit man that things fast

[@alpha-9639]

The driver knows how to drive fr that's some good shit right there🏁🏆

[@jaredbourgeois8732]

four strokes always dominate

[@madcuzbad8205]

But they have to be twice the size of a two stroke

[@pakkiaman2]

and half of power...... kz10c engine 125 2 stroke at max power make 50 hp

[@jaredbourgeois8732]

so what.. four strokes win races and have more controllable power. four strokes DOMINATE.

[@pakkiaman2]

??? kart engines are 2 stroke..

[@jaredbourgeois8732]

pakkiaman2 your watching a video of a four stroke kart. right?

[@alanmotoscba]

those 2t are very fast too.! nice video mate

[@DiegoAlvarez-yo4lc]

You overtake the ones who are overtaking. This is nuts

[@jeenyussnow101]

G FORCE WAZZUPPPP 💪💪💪 amazing thing you drive there and good driving I enjoyed

[@booster_740]

Dude i really love the intro of your video it's casual

[@CyberMacGyver]

Power to Weight ratio is INSANE 😨

[@guilianocipria5218]

Good driving lines for a big heavy boat

[@michaelwhite6110]

He smiles the entire time! Lol

[@jaywerne3812]

This is the best onboard shifter experience on youtube

[@Wayne_Robinson]

Woo hoo! Those were some fun laps.

[@aaronisgrate]

stupid fast. cant beat the torque of a 450. i have no doubts that kart would hang with nearly any car at any short course.

[@nielsreiziger4850]

450's are great easily 53hp+, got a 13' KX450F the torque is insane

[@EricFB]

On a short course it would eat them up.

[@trevorodom1930]

I think smoke a car the power to weight is insane on these

[@Track1recordschannel]

This is a really cool video. I always wanted to build my own

[@rogerw3818]

Geez Louise, that looks like fun.

[@Maccaroney]

Jesus Christ.

[@haydencollins6761]

That thing hauls the mail!!!! Badass!!

[@Boemel]

I need this in my life. Now i'm always thinking of buying something fun, either a beater car, a small motorcycle or fix a junk cart with a silly engine.

[@eye2985]

DUDEEE THAT TRACK IS SICK WEVE RACED THERE BEFORE😎😎😎

[@jasonbell1950]

To those who say this is sped up, no it's not. I've ran this track many times and have had Darius pass my in that beast numerous times at Laguna Seca back when they first let the karts get on track there. It was kind of funny to be doing 100+mph and have this wicked 4-stroke come blasting by my stock moto CR125 like I was sitting still! Good times.

[@andycliffordkarting]

Jason Bell people will always question awesome things 😉😅 We race these in NZ and can back you up here! 125, 250, 450 or 500... they are all fast as hell in a shifter!

[@sharpjm85]

You can tell just by how quickly he gets into the seat at the beginning that it is sped up. Watch the video at 75% speed for realtime.

[@Dariuskhashabi]

does that tin foil hat make your head hot?

[@TheBlackopsbeast360]

vggvvggjjh the engine note sounds correct for a YZ450 engine....

[@derekbest9703]

1:45 its def sped up in some places lol. Why defend it? Its still cool none the less..

[@RS3-MT10]

Awesome bit of kit but should have gloves on, karts can go over and other flying debris not to mention bees/wasps etc, again top machine.

[@jzero32]

Most of the tracks we run - New Castle Indiana, Millville N.J. , Englishtown N.J. won't let you run a 450 on them. Damn that is cool.

[@Kidzspeed]

Hey, I have been to those tracks too! Oakland Valley Race Park is my home track. Ever been there or to GoPro Motorplex?

[@ILLUDIUM_Q_36]

Damn no gloves ?

[@pvanb291]

Yeah, I agree! I was racing a Suzuki RM250 grass kart a while back. We weren't allowed on the track without gloves - even for a practice session. On a tarmac track, I wouldn't even get in the kart until I had gloves on!!

[@Dariuskhashabi]

If you really crash a kart gloves are the least of your worries. You flip and break your collar bone, or neck! \

[@pvanb291]

Crashes can happen in slow parts of the track too, where you won't break things. You may come out and have your hands scrape on the track, or burnt on a hot exhaust - both of which are a lot less painful if you're wearing gloves!! It's just a no-brainer - always wear gloves and helmet!

[@agamer334]

Darius khashabi that's no excuse to put on a pair of gloves

[@tannerVBHC]

loll fuck gloves

[@zacharyabdollahi7760]

Awesome, you should race that thing

[@krazor8]

Might as well go for the kill and straight a 600cc ninja motor on it...

[@EnglertRacing96]

that would have to sit behind the driver making a stupid long wheelbase kart that wouldn't come close to the lap times a standard setup runs.

[@djmiller5563]

Great driving and speed. Very nice. Although, I can't help but comment on your layout; Your "flat-bottom" steering wheel is a little off, and I bet you could increase your lap times if you installed paddle shifter's rather than that "lever action thingy".

[@Kevin_Yagoonie]

looks like a blast!

[@brianonthego]

Very cool. Great driving.

[@houseoffire72]

Looks like a butt ton of fun..!

[@ceetwarrior]

So sick!

[@remisimard9]

Pretty similar to a FSAE car. They are often 450cc or 600cc engines, or electric

[@michaelgrossman5528]

how much where can i get one nice driving too

[@frankyalvarez7160]

the video should be named " if sonic drove a go-cart"

[@Dr_Xyzt]

Damn, that thing is badass!

[@naomialkowari4887]

That go cart looks amazing would have some fun with that ..police wouldn't have a chance catching me...ha ha ha wayne.c.scotland

[@trevorodom1930]

It’s one thing to have a 125 engine in these but a 450 holy sh!t

[@richarddevaottien7724]

A Yamaha quad Raptor700 might be good in a kart ?

[@dylanhammett4583]

Let me pick your brain a little bit I'm building a cart with a yz426f Yamaha motor what gears are you running there's 14 teeth on the motor and axle came with 28 teeth but I have to get a sprocket 520 for the axle any recommendation

[@staticcorvette5998]

Who's the handling on that thing? I'm sure that engine must throw the weight balance quite a bit

[@jakedragsknee]

Do those things eat tires pretty quick. Those little things are just getting hammered 😂

[@stevesimon460]

I have a shifter cart with a 2005 crf450 motor with a 523 big bore on

[@bssignorful]

looking good out there.

[@romainhebre]

What is the goal of the handle on the left behind the steering wheel ?

[@jb5music]

I remember when I was a kid and there were McCullough go-carts that then gave way to Yamaha 100s... I thought how stupid little one speed 100s with no transmissions... why don't they use motorcycle engines with transmissions? Anyways, grew up and didn't really follow go-carting for many decades but just glanced at these videos decades later... hey.. go-carts with motorcycle engines with transmissions. What a great idea. Who thought of that?

[@Strakos0]

Whoah, mister, is this faster than a KZ2 KART??! It looks like that! Ah. So smooth racing piece. What should be the average price for buying? Any troubles with kart? I am so curious because I wonder what it takes to become a kart racing driver..ah. Why there is just no possibility to rent and try. Or to make a "public", free qualifications...

[@Xcrf150fX]

do you really have to build your own? i can never find any with dirt bike engines

[@armenvegas]

I've got a dd2, love the power on it, then got a honda 125 6 speed love that.... how the 450 compare? Lol

[@adrian.vermeulen1670]

wow that's a fast kart 👍

[@darringoodbrand6603]

Thought that the 250cc 2stroke carts would give this 450cc 4stroke a good dam race

[@conspiracy703]

Who built this sucker. Been wanting to do this for a while with kx450

[@alexanderharris2035]

That is awesome Man thanks for the info!

[@bruced5587]

Looks like a blast!!!

[@seanstacy9557]

On a real note, which do you guys think is better: 250cc engine or 125cc? I've had both and only had a 125cc on a Kart though. I personally like the more usable power of the 4 strokes, I think the torque is very helpful especially when cornering.

[@Dariuskhashabi]

I believe they only race 250's. The added weight of the 450 definitely affects the handling. My motor was mostly stock. A modded 250 would be faster imho. Even the best of the best 125's would probably be faster, but I doubt funner.

[@woozhi9218]

Dp you have to rev match if it is a 4 stroke

[@waawaaweewaa2045]

Such a sick track where is this?

[@edgarcoloncruz99]

Good ass driving!!👍👍💪💪

[@justingrant3648]

What is a $400 one that can get to 50 or 70 mph that looks cool

[@paulcookson4674]

Fast and well driven.

[@debeukeboom5671]

Dang that thing rips

[@AndreiLomov]

Nice video.

[@bonkeydollocks1879]

Christ that looks fast

[@3346501]

looks like s blast !!!

[@ladyaurora8434]

Does the kart have a clutch since it’s a dirt bike motor?

[@centuryfreud]

No gloves? WTF?

[@samhesketh]

User37495936 not a race officially

[@jimmyrustled4373]

I know...first thing I thought...no gloves???

[@sameuljones5496]

User37495936 real man unlike you

[@hahanew]

So appreciating your fingers is unmanly? Let's see you support your family as an amputee

[@mikemcgarry3553]

no gloves is stupid !! ....too cool hey? You made yourself look like as ass mate !!

[@leeanamercado8836]

where did you tap the pulse line for the fuel pump on the motor

[@Dariuskhashabi]

right on top of the intake before it goes in the head.

[@xAlienWarfareGamingx]

I really need to get one of these. Either that or buy one without a motor and swap the motor from my gsxr 750

[@mrcool4196]

How u got it to press start with a 2008 motor

[@mcooferton1113]

Please tell me theres a class for 400cc karts

[@pdtech4524]

Seriously if you value your hands and fingers, wear some decent leather gloves! :) I'm talking from experience, as a biker, in my youth thought it was much cooler not wearing gloves! Everyone kept on at me to get some and wear them, eventually I gave in, literally the next day I was hit by a car reversing into my path, the gloves got wrecked but my fingers and hands were all intact!! :) Just try to imagine getting through one day without your hands!

[@zachsmith9089]

Is this sanoma raceway? Cause I've raced there before with me Tag-senior

[@DJWolves97]

Zach Smith Yup! You should come on over to Gopro motorplex!

[@PaulsPlace]

Z06 of go-carts!

[@armywithluv9780]

Would it ever be possible for a shifter kart to have shifting pedals behind the wheel like in F1?

[@TheBlackopsbeast360]

Oickled Pnion there are dd2 karts which have a paddle shift, they’re only two speed though, hi and lo. For a 6 speed sequential, it’d be more trouble than its worth, as in F1, those paddles are just buttons like on a video game controller that tell a hydraulic to shift the transmission, in a shifter kart, you’re actually physically changing gears with that handle.

[@armywithluv9780]

Mason Kurien Oh I see. Thanks for the information!

[@poohkie9389]

I like how he couldnt overtake even though he clearly has a wayyyy more powerful engine and speed

[@poptartheroes]

And once you're done driving, you can look over to your right and give your engine buddy a good ol' pat!

[@poptartheroes]

Marco Brancorsini, it’s well worth the trouble he did for us.

[@marcobrancorsini2479]

Good point

[@SSpecialDelivery]

Curious about what you did for engine mounts... Custom or purchased some

[@Dariuskhashabi]

custom welded

[@LAZY-fido]

Is his steering wheel upside down

[@zanecrocker9091]

Does it go suuuuper fast

[@groomlake51]

Scotty give me WARP speed 😲

[@hilltoprestoration]

Have forearm pump pain just from watching him hold that wheel.

[@xabbbi7231]

where is the video filmed ?

Ayyyyeeee thats sonoma i drift there!
