750cc Custom Cross Kart TOP SPEED RUN
HTML-код
- Опубликовано: 8 окт 2024
- After finishing the 5 point racing harness and extending the roll hoop, we take our 70+ horsepower 750cc cross kart powered by a 1982 Honda CB750 motorcycle engine out for a top speed run. Our custom buggy performed well- it had a high top speed, great acceleration, and it handled very well. Next up, custom building front brakes!
Thanks for Watching!

Traffic court Judge : So let me get this straight son..You were doing 80mph.... in a go cart?
Ike interrupting the judge... "82.9 your honor."
Also your honor it was not a go cart it was a cross cart.
Judge be like it will be fine just $500 dollar fine and 100 hours community service each LOL.
80 in a shifter cart isn't hard to do. Hell non shifter 212 you can get up to 80 with say a 36/17 tooth setup on 12" tall tires.
This particular setup if they wanted to and had the balls to do it, i am positive they could get up to 150 easily in say a half mile scenario.
@@VA-ng2ve with aero, maybe 130-140. But as is it would be too sketchy to hit probably even 110
How you guys don't get busted by the cops is beyond me. We used to be able to do that sort of stuff 35 years ago but these days neighbours might as well be an extension of the local cops. Love your work guys. Back in the day, we used to cut the gearbox of old motorcycle engines and use a single cylinder Villiers 2 stroke engine. Weld a sprocket where the clutch used to live with a centrifugal clutch on the motor crankshaft. So many hours of fun..and never any cops around.
If you watch this site, from the first carts till now you can see how these two men have learned by doing. Each build has been more complex and better executed. AND most important they lesson to the fans. Great job guys.
Thanks
Front brakes are a must going that fast... And bigger tires wouldn't hurt either, might even give you a higher top speed :D!
I agree 100%. Front brakes, and slightly larger tires (at least in the rear). And that sweet sweet paddle shift setup as well!
Yep front brakes for burnouts
They'll need new tires soon anyway lol
When I Big Board mine, I had crankcase vent problems. I put a crankcase vent on top of the valve cover work just fine. Great job guys
This episode pleases me very much! This project is the culmination of the show from the beginning up til now! This cart is amazing and is every kids dream, even a giant 36 year old kid like me!! Love yalls channel and chemistry! Thank you for the great content and keep it coming please!
9k RPM + no scatter shield = I’m lucky I’m still here😳
It is an awesome build, and yeah ya might want that scatter shield lol
So time for bigger cams?
:|
Fuckin rowdy
derk nobit hell ya
I was looking back at older videos and some subscribers pointed the hoop being to low when you guys were mocking, I’m glad this one is getting fixed and not it’ll be fined! Lol we need you guys around for more awesome content!
Carsandcameras post 670 tractor crash: we’re gonna wear full safety gear during every speed run
Carsandcameras on this speedrun: *not wearing full safety gear*
😂
Austin Friedner If I’m perfectly honest, the fact that they’re not wearing safety stuff doesn’t really bother me that much.. and you’re right, it was pretty stable, I posted it mostly as a joke and well carsandcameras surely know how to send it, even without safety gear
@Austin Friedner
Whether or not that cart is more stable then the 670 tractor at those speeds that roll cage would not hold up to a rollover they should be in full safety gear. Testing is where your worst accidents happen Ask any race car driver that's ever gotten into a bad accident, safety gear saves. That being said those guys definitely know how to rip it up😀
Make decent exhaust, you get +5-10MPh
Put original carbs back=10Mph more
Was that JASO rated oil so your clutch doesn't slip?
It certainly wasn't lol.
Nope that was car oil
It’s just for testing purposes.
This video was absolutely next level for you guys the way it was done. I'm no expert but it just felt so much more professional. And it didn't hurt that the cart is an absolute beast.
Glad to see no one got hurt in the making of this. Solid asf ! 💪🏻
Your straight line, high speed stability is fantastic! Great job!
Make body panels and put on some wings, take that fukr up Pikes Peak.
lol :D
They'd have to turbo it to counteract the altitude which would be sick as
That sounds lit as hell
@M Diggingit plastic is not to heavy
Racing slicks, a quick-shifter setup (if possible), turbo, longer gears, suspension adjustment (maybe stiffer and lower?), and body panels will make this a racing machine.
Great stuff in this build!
No real scary stuff like over powering a mini bike
This is built to run well , crazy fast and soon very safe.
Love it
I love you but you just put car oil in a motorcycle with a wet clutch system... friction additives and wet clutch do not mix. :(
Brian Little :(
i did it one time one a really old xr600 engine... it blew up...motorcycle oil isnt much more expensive than good car oil
Car oil isn’t that bad with older bikes. It doesn’t last as long but it’s really not that bad
@@stevedavis9256 I ran my old xl175 for years on cheap car oil with no issues
this is what happens when people make fun of lube techs.
By far your best build yet guys. I love it. Please finish it and bring it to it’s full potential!
Damn! Ike drives like a madman, I love it. Thanks for sharing guys
By far the coolest project to date fellas! Love this 😆
You need to put all 4 carbs on it should be faster :)
@@AiOinc1 yes turbo
More ≠ better. Two well tuned carbs will work better than 4 stockers
@@VasilyBuilds not true 4 carbs have more power it is so much better
I agree. I said a couple weeks ago you all needed the four carbs. It was designed that way for a reason. And the two you have are meant to feed one jug each.
Having 4 separate carburators on it will be pain in the ass to calibrate
Wow that's what everybody's been waiting for
It's really nice to see how far Johns fab skills have grown since you guys started this channel. Thanks guys, real nice kart.
Thank you!
Great job, guys. This is your best project yet. The Rail can’t hold a candle to this thing.
Btw your using oil that's not good for wet clutches. You need a non detergent car oil or motorcycle specific oil
Propane and propane accessories. Shell Rotella15w40 is the way to go on air cooled motorcycles with wet clutches.
No 10w40 because other oil too thick
i like 10w40 too
The weight of motorcycle oil depends on if the bike is air cooled or water cooled. Water cooled use 10w40 air cooled like the motor on the cart will use 20w50. But yes they are using the wrong oil and the clutches are going to be effected.
@@louismisciasci8066 I looked up the oil used for THAT motor in the manual. it says 10w 40
DUDE!!!!! That Buggy Rocks!!! She hauls buns. Ike you better be careful it might be the Mower all over again, only thing is this time you all have a roll cage and 5 point harness. Great job guys I think the Ducarti may give it a run for its money. Keep up the great work. Faithful Subscriber from Southeast Missouri
“Cross Cart VS Ducarti” at Drag Strip
Cross cart will run out of steam due to the gearing. It's geared way too low. Ducarti has shown it can do over 100 and get up to speed very quickly. Also less weight to deal with?
Unless they put some taller tires on it, it has 0 chance.
@@VA-ng2ve this is why I want to see miata rims and tires with All Terrain T/A's - General Grabber AT2's are amazing, have great tread life and are grippy in the dirt and mud.
No need... a 125cc shifter kart would take that thing to court. Poocati? Pff... that'd be like pre- pigeon Mike Tyson beating up a 3rd grader.
David Fountain I thought the same thing
Ducati will crush it!!!!
You guys should be proud. That's a great job you two have done using your talents and making a great cross cart. 100% bad ass
That sure is an odd way to shift. I’ve never seen someone reach across with the rite hand to shift with it on the left.
They should have set it up for left foot at that time!
Now that was a proper thrashing John, freeking sweet. Can't wait to see more of this unreal build.
Maybe a little slide slot to keep the gear stick from flopping??? Totally crazy. Luv it👍👌
Thanks, we're planning on replacing it with paddle shifters
Sickest build on RUclips. Just pure fun
You need a hoop further forward otherwise your still going to be crushed
I said the same thing last video cut the hoop off remake it or hell do a whole new chassis cause that's not going to do much in a crash especially going 70+
@@zerodamonsta942 I been saying it since they made it lol its common sence but they don't acknowledge viewers comments.. I can't believe safety John doesn't realize this yet
All they gotta do is set a 2x4 on the hop and over next high spot steering wheel and they'll see they're body will be done lol
Did I made comment on this lol I said that I've been building chassis for carts that are called Whistler's and I build chassis for snowball derby cars. I have to stamp each chassis to rate this safe and this right here is not safe it's even not allign for christ sake. I'm just gonna either they gonna break some bones or not come alive you're not suppose to have roll bars above your head at all.
I've been loving this build guys. Since y'all have such an over puttered machine with seat belts, y'all really need a serious roll care. I know that with the stance the kart has it's not as susceptible to rolling over or getting the wheels off the ground it's just a good thing to do for y'all's safety so we can keep enjoying more great builds into the future. Keep up the awesome work.
Isaac, when they say we are having a "Fire Drill" that is NOT what they mean!!!
So glad this is coming together, and will be nice to see it finished up soon :)
Just remember these are Kart tires they use are not suitable for that kind of speed or heat (and typically don't have warning indicators) like specific race/road ones.
Just be safe and remember to use the correct equipment if building anything (also check with manufacturers if you don't know)
Right there on the sidewalls "NOT FOR HIGHWAY SERVICE" at 15:47 I said it before in an earlier video guys....CHANGE THOSE TIRES To Speed Rated before something very bad happens. Zip~
Off road tires allows more top speed, because there is less friction on the road. If you replace the tire with slick or radial, it will be worse. It can allow more traction, but creates more friction.
GREAT!! Thanks for fixing the shifter.
Cutting Blade: Is on fire.
Isaac: I think the blade's hot.
Me: Laughing my head off because this is one of the reasons I love this channel X'D
Hell yeah brother!!! MERICA!
needs a roll bar over the tank,,sliding on your head is less fun on fire.
Pussy
Brent Bloom 😂
True
I agree it needs tank protection and also needs roll protection over the steering 4-6 inches in the clear really you need the full roll cage the way most rail sand buggies and most of the 4 cyl carts are doing. and some chicken wire in key locations for keeping your hands inside . these things are supposed to be upside down. Plastic needs metal. the way it is now when that things upside down you will break the wheel and probably your hands. My sister had an odessy and i'm sure it wasn't half as fast as that 750 but it got the rubber side up often. In fact that wus part of the fun because you were safe when it happened and the vehicle seldom took damage cus the small engine kept the speed down as long as you had the harness tight. edit
HaHa ha I see that during the time that past you had already done the full rollcage. Now your safe from everything but cliffs and pickup trucks but the driver is supposed to miss them. I know your michanic don't want to hear this but get a motor cycle mechanic for a buddy so you can borrow his carb vacuum gage set do you can balance them carbs or get one to do it and let him take a test drive. its like the back pressure extractor issue those carbs are balanced and jetted for a certain length pipe and collector, Besides its just more pleasent if that is humming in your ears not screaming. I really like the suspension setup Looks great. btw its not a gokart they have solid axels. have FUN!!!!!!!!!!
Depends on what you consider fun, how else would you want to go out?
yes definately beef up your rollover hoops and side impact bars.any number of scenarios can happen at any time.It would be wise to build for the wreck and dress for the crash as well.Keep yourselves safe by not skimping in the protection dept.We all like you to muchfor any badnews.AND ILL LEAVE IT AT THAT.GOOD BUILD YOU GUYS
as a race car builder that cage is cringe lol ,good luck boys hope it makes good speed
Cringe, you’re being kind sir.
Dude I swear.... been around racing my whole 46 years and this thing scares the shit out of me..... the "halo" bar is not tall enough and the shoulder straps are not mounted low enough in the back! Good luck if they ever flip it....
@@randyughlee1750 makes me want to fly up there and do it for them lol. love there content and would hate to see them hurt
@@so-flamotorsports7491 I know... and to see them welding with the belts so close... makes my skin crawl... I love the content always maybe not the execution most if the time! Hahahaha
It needs a roll hoop in front of the steering wheel as well so you hands won't get crushed.
Not bad top end for such small tires! You guys designed that thing pretty well!! Making me wanna clear out space to build something with parts from the salvage yard down the road from me a piece...
Getting more air & fuel into that thing could make it down right bat shit crazy!!
Try Lenox holes saws, cutting oil, and no more than 120 RPM on your drill. Hole saws should last a lot longer for you. Great work as always!
It's cool to watch John get more and more confident in his fab abilities. Your welds have gotten SO much better buddy keep up the good work!!!!
The beast needs a light bar that goes from post to post on the rollover bar!!! 🇦🇺💯😎👍
As usual, you guys DID NOT disappoint!
😎😎Cars and cameras go to mexico 🔥🔥
So cool! I've wanted to build something similar since I was 13 years old. Now I'm pushing 30 and I am yet to build it. This video has convinced me to get'r done! Good job guys!
Finally!!! Next drag strip😋
yes its a home run guys i like it it's a hot rodman watch out for 2nd gear on that they are good for jumping out when they get some wear on them i have seen this a lot nice car man smooth just right
I sure hope y’all know the folks who live on that road! Haha.
Exactly!! If not they know them now. Wonderful way to introduce yourseff
That cinematography and music was seriously outstanding!
Please share that song!!
Call Rather b. Tell him to BRING IT!!!!!
I am a retired mfg engineer and I am so impressed by the ingenious work from you two "go fast" addicts. Keep up the good work. Next cross kart should be a Kawasaki or Yamaha 1000cc or 1100cc from the early '80's. You can buy them cheap !
Lol everybody called that hoop being to low because the seat height was overlooked
Edit: this thing is badass
My favorite build of yours so far good luck out shining this one but I know you will
You should probably also think about front wheel brakes. Especially at over 80 mph.
100% I tried using a 100% front bias on my car and there was a HUGE difference in stopping power once i put the front to around 70% again.
Y'all killed it awesome build
That should take motorcycle oil because if the clutch shouldn't it? I might be wrong.
this channel only gets better and better.....
This would be my vehicle in the walking dead lol
Put a 4 into 1 exhaust on it. It will sound so much better.
Probably get some more torque too
A wise man once said: “A vehicle should never go faster than it can whoa “.
John THAT shifting was AWSOME
Shifting with your right hand on a left hand shifter?
MAN THAT THING SEEM TO WORK GOOD AND FAST GOOD JOB GUYS
"We want to keep it."
Adds car oil to the motorcycle engine.
I'm sure the clutch will be fine.
Ahh good ol laying patch in the figure 8 LOVE it guys another great video love my 2 times weekly dose of carsandcameras!!
Thanks
@@isaacitllbefine7231 Hey I'm subbed to your channel too =D Love the old school car work there as well !!
For your safety you NEED another hoop on top. You head is NOT protected the way it is. And for the love of god DONT weld without covering up the safety belts. I was yelling at both of you for doing that.
I love the way it sounds!
8:42
Best clip🙌🏼
nvm 13:55 is the best clip
Definitely my favorite channel now you guys rock and are a helping me with my first build and giving me all kinds of ideas thanks very much
Someone with an engineering shop please make them a proper cage. This thing does nothing but give a false sense of security.
If it is built ok it should be fine steel is steel and their welds are all goods
Great job guys cant wait to see this evolve.
well, since it hits 80, put a set of lights on it, and register it as a home built
That was a blast to watch, can't imagine the rush to drive that thing, well done guys.
Bruh my cousin almost died from a shifter cart engine blowing up beside him you guys might wanna put something behind the seat so you don’t have shrapnel flying into your back an head if the engine blows
Best project yet!!
Top speed runs in t-shirt and shorts. You'll never learn.....
It'll be fine
That’s what I was thinking too. And they have leathers they could wear.
I realize it’s August and all, but if they had a suspension failure at 80+ it would have been a lot more painful than being uncomfortably hot for a few minutes.
@@charged I honestly dont think they will take it seriously until one of them gets really hurt.
Aerodynamics
Bro he uses a grinder with earplugs on if he felt he needed gear he would put it on
Nice work guys! Looks like a lot of fun!!!
Jon why do you shift like that, makes me nervous🤤🤤
I believe it's to do with the shifter being on the left side
so he has more steering control
He's a lefty---he's keeping that left hand on the wheel at all times!!
@@trevawhitmoyer682 if u say so.
I found it weird too.
Looks like an alignment "It'll be fine" problem
This video series inspires me to actually try to finish and clean up my projects. Keep it up and keep improving!
DROP ME A THUMBS UP IF YOU WOULDNT TRUST THAT ROLL BAR LOL
Best build you've ever made. Looking forward to seeing more powerful builds in the future.
That son of a gun is rip-snortin badass is like almost perfect gearing just remember you put taller tires on the back you're going to have to put a taller sprocket back there to keep the gear the same
That friggin thing is happy feeding donuts all day. Great work guys
It’s a RWD civic at this point😂😂
Just needs a fartpipe for the muffler. Lol
Allen McKinney lol
Best thing you guys have built!
That shifter needs improvement other than that pretty cool build
That is one sweet creation guys. IT’LL BE FINE!
Headrest please love you to much to see you snap your neck. I did “lose” a wet clutch to regular oil but it will be fine
It's good to see proper emphasis on safety. Congratulations!
Still think the back needs bigger Tires
You guys nailed it!!!
Thanks
With an air cooled engine, you're better off with 20w50 oil.
10w 40 Honda oil.
You don't want thick oil for engines that are air cooled
@@tebibyte2357 Don't tell that BMW and their air cooled Boxer engines.
@@tebibyte2357 this is wrong. You want thick oil for air-cooled engines because it transfers more heat to the case, and because it runs at much higher temps, it thins out to be more useable. Putting thin oil in air cooled engines causes it to get too thin when it's hot and you lose protection.
In the winter the engine won't run right because the oil too thick
Good Lord that thing sounds amazing. So frigging cool.
You should really get better at fabricating before playing around with speed and power like this...
What a creation, looks great, runs great, sounds great and no injuries :-)
