670cc Go Kart Performance Modding
HTML-код
- Опубликовано: 5 сен 2024
- This week, we finally put a dual carburetor setup on our 670cc V twin go kart to get more power out of the engine. We also throw on a steering wheel, and two Predator 212 race mufflers to quiet it down.
Thanks for Watching!

John's famous quote of the year: we don't have the nuts but we have a solid rod
When he said that I died
thats what she said.
"It's quieter"
"WHAT?!"
"IT'S QUIETER!"
HAAAA! It sounds bad assssss.
Holy young John! just watching older videos I never got a chance to watch, You fellas have came so far, perseverance has absolutely paid off for you and Ike, Thanks for the quality entertainment!
I appreciate how you two are always thinking outside the box and never worried about trying something new or outside of your comfort zone. Makes your content interesting and enjoyable! Keep it up guys!
thanks
I found "Cars and Cameras" several months ago, I was gonna buy a mini bike and started searching videos on RUclips. Needless to say I bought a Kart instead, a Murray that was on craigslist, Predator motor, no suspension and all the fun $200 can provide. Now i'm doing mods and saying "It'll be fine" A LOT. Love the channel, I think I may be hooked.
I find myself grinning like an idiot whenever I watch you guys do this stuff. please don't stop.
lol awesome
"Where are the pods"
"We dont have pods"
"Aww man"
"We'll have to use a sock"
i just binged watched every episode, about 15 hours worth of content. let me know if u guys are looking to hire a cart technician i am now certified. lol
Damn, I work 3rd shift. Just as I was going to sleep, you upload!! It'll be fine. Let's watch.
"No Nuts, SOLID ROD" - A Regular Kart Review
I can hear Mr Regular already.
NOT A CAAAAAR.
My favorite line from you guys "For testing purposes only."
Keep up the great work!!
I like that you don't play music. A lot of people do like hearing the tools
THE FACE IKE MAKES ABOUT GOPOWERSPORTS IS AWESOME 😂😂😂😂😂😂
Its so fun when Isaac uses his "high pitch" voice
You guys always deliver. It'll be faster and if not just paint some racing stripes on it that always works.
In all reality John and Ike, there's actually 5 - 90° turns into the cylinders each. The hidden 90° is inside your cylinder heads where the Air/Fuel enters the head and thus needs to get by your intake valves before entering your cylinders. Not only another 90° but the most restricted of all. Being a Honda clone V twin the Chinese have ripped off the intake port's aren't of the best flowing qualities and are pretty square in shape. Plus the air/fuel needs to make its way between the valves and the seats and around the valve stems. So porting and even some filling within these ports maybe necessary to produce a better designed intake and or exhaust port on these engines. Having built a professional racing engines for many years now and actually a few being V twin Briggs Vanguards and dozens of single jug engines used in racing circuits, these small engines were never intended for performance use. There's plenty of people out there that have proven tricks to getting the best possible potential from such engines though which might not seem kosher to say your car engine or V8 race engines. When you're able to buy off the shelf performance parts for such things, well these engines are a little bit more involved in the creativity process of achieving the best results from parts never intended to fit these types of engines. Nowadays there are many small aftermarket companies though producing quality parts and performance parts for smaller engines. ARC being one of these companies who builds custom parts for your more common engines. DYNO CAMS being another and ISKY Camshaft also sells products like valve springs, locks and retainers necessary to match up with your bigger Camshaft profiles. But you guys are starting off with basic ideas and dreams, which we all started from. The bonus of having fun with what you do for work is the cherry on top for sure! But just wanted to let you guys know your doing great so far starting from scratch! I did 3 years of small engine in schools and worked in machine shops growing up to eventually running a small engine repair business for most of my life. It's now morphed into engineering and much different work than I ever anticipated I'd be doing at say 18-24 years old Lol. But we live and learn, this is life, and for some of us we find ourselves hating what we do after the honeymoon phase wares off, but because it's easy enough to do we will tolerate this kind of unhappiness for sometimes our entire lives. It's when you find something that is fun or you enjoy to do, sometimes challenging, which keeps things interesting so you don't get bored with it. This is the ultimate dream come true, being able to work from home or close by, doing what you enjoy doing and making a halfway decent profit doing so! Not many people have this all in one bag, so please never take this job fo4 granted and continue to have fun doing so and the money will follow as well as your people who enjoy watching your videos. Congratulations guys you are on the up and up. One last suggestion, is to never stop learning either, the ones who fail or fall the hardest, are the ones that feel they know it all.
It Sure does rain allot where your at... Love the the Get er done attitude....
Awesome as always. Can't wait for Part 2.
I always look forward to your weekly uploads. It's one of the few that I actually full screen. Keep up the good work.
thanks
y'all should build one with a 600cc motorcycle engine
the engine out of a CBR 600 rr
+physx of gaming yea or an r6 either way those go karts fly
what a shame
they REALLy should do it , i think it is going to be even faster than this 670cc go kart. PLEASE DO IT CARSANDCAMERAS ~
look at crosskart. that'll be great
THAT WHEELIE WAS F**KING SICKKK
I love it how Hecht the holes in the plastic so the flanges can fit though the holes but to remove the plastics they either need bigger house or they need to remove the carbys
Imagine putting a turbo on that thing... Jeez that'll be one of the most brutal contraptions to think of 😝
I was doing a diploma of engineering course & as well as safety glasses, sometimes we also had to wear a face shield as well, like when welding. It's a pain to see through sometimes, can fog up, but better safe than sorry.
I've been doing washers for flanges for years, they work great.
freakin sweet kart. I've wanted to put one of those Vtwins on a go kart forever. Nice work, I was pretty impressed with how well that sketchy ass throttle set-up worked lol hurry up with part 2!!
Been waiting for this videos for so long!! Suggestion. You should take a old motorcycle engine and make a racing kart from scratch.
Anxiously awaiting part 2!!!
The cat that Ike scared with the truck was in 12:27
In the video of the off road go kart find
TY Jackie, and good job guys!!!!!!
thanks
At 12:30.... the cat is like i'm getting the F-out of here again!!! ;)
it would be nice to see everyone contributing, even Jackie, just say hello to us!!
At 12:30.... the cat is like i'm getting the f#ck out of here again!!! ;)
You guys should do a super pocket bike build to spice things up?
Do you think it'll have slower or faster acceleration than before?
faster
you guys are almost at the quarter of a million subs yayaya
+Anthony Garcia i remember 6 months ago it was 70,000
It will be faster
I'm sorry about your eye
Very cool with the twin carbs guys👍 Mufflers look like mini supertraps lol
Hey Ike and John, I saw something that you guys may need to consider for this beast.
I watched a video last week of a predator 212 with a roots type supercharger on it. Guy fitted an old VW smog pump on the engine and ran it as the supercharger. Freestanding the engine made 17psi but operational boost was around 10psi.
Dude, that thing sounds so bad ass when the throttle is wide open!
I'm shocked Ike didn't know that you want to space out those carbs a bit, long intake runners increases velocity which increases bottom end torque in a naturally aspirated engine
"Whuder u talkin bout boy"
"We don't have the nuts"
"But I do have a stiff shaft"
😂😂😂😂😂
Cory Sennett he said but I do have a solid rod
Might be a little on the lean side, dis coloring those mufflers that bad that quick. You guys may also get a little more out of it by synchronizing the carbs too. You'd just need a port in each intake and a length of clear vynil tubing with a little water with food coloring.. Attach each end to the ports on the manifolds, tape the center of tubing down and back up a yard stick. Fire it up and adjust the idle screws until the water is the same height on both sides of the yard stick. We used to have to do this on old 2 cyl motorcycles with 2 carbs....
Haha Ike is always doing some dare devil stuff. Like when he first did a wheelie on the 670 , I thought that was crazy af! But then you top it off and do it in the dark with a new setup! 😁 haha hats off to you guys 👌🏻👌🏻👌🏻 that's some handmade quality stuff right here
lol. thanks
sounds great with those new can on it. the open pipes just sounded unfinished.
nice little burnout ike
Love the videos, wouldn't run a cart up just a jack though. Works well once in a while but the more you do it more chance of it coming off for some reason.
can't wait to see what it will do
some great engineering goings-on there, sounds and looks cool with those mufflers..hopefully they don't choke it ✌
Check the spark plugs and see where the fuel is at. Might be leaning a cylinder out with two carbs or going too rich. Looks good keep up the good work
its about time u put somw back pressure on that motor!!! any real gear heads goin tell ya u need back pressure to make horsey power!glad to finally see something right lol
Turn it into a stroker, lengthen the crank stroke and shorten the piston height and make mad power out that thing and get a custom cam and rocker arms and that thing will be a monster on the engine alone then EFI the thing and make more power on top of everything else (just a little food for thought for ya )
In all seriousness though, Isaac is a hell of a backyard engineer. Much respect
Finish dialing that 670 monster in and chase 100+ mph in that bad boy :)
put those huge rear tyres from the new offroad kart on it, that would look awesome.
OUCH!!! Funny thing is I had a cornea abrasion last Sunday. THAT SUCKED I was wearing a full face shield too!!!!
Where is the continued video? I want to see that thing go! The washer/flange idea was genius!
They make a pick up sock for fuel systems so that when fuel runs to the rear of the tanks it will still draw as they did in airplanes upside down. Saw you having a problem on one of the drift tricks.
that kart is a beast
2:42 I feel feel you man, I was working on the fuel line on a 1970 c70 chevy dump truck with a 427 v8 and holley carburetor and I had to reflare the new line from the pump to the engine cause the other person did not well I was wearing safety glasses to and got gas in my eyes I immediately washed it out and continued to work on the truck
Like your backyard engineering ... Keep up the good work !
thanks
@ :38 bush has a name :( Poor Jeb, lost and forgotten
who is the 3rd member of the team behind the camera? Oh, you just said "Jackie". Well done Jackie.
paintball mask, impact resistant and they have a foam seal around your eyes. plus they also protect the rest of your face from large chunks of flying death wheel when they shatter.
try using the gyro cables for the freestyle bikes to make an easily adjustable throttle set-up. I used these on my dual carbed bug back in the day
put some pod filters on for proper tuning
you guys are my inspiration for my builds i love all ur video and this go kart is bad ass!!
thanks
CarsandCameras you should adapt a led bar in the front just a suggestion
WOW - it looks F A S T!!! Now get the tin cover and some air filters on that puppy!!!!!
Good call!!!
Awesome vid you should get high flow air filters and open up jets in carb possibly some nitrous but that may be over kill
Nice job on the build and video! It would be interesting to make a couple longer intake runners and compare hp/torque between long and short intake runners.
Rotfl! The wheelies make me giggle! Nice job guys
She is real good with a camera.
I am happy Ike is more comfortable infront of the camera as he was early on in this channel, Quite a funny fellow :P
thanks. lol
Not only that, your picture for your cars&cameras shirt is hilarious!!
Do you happen to have women's tops of "It'll be fine?"
Everyone go buy there merch :)
I could see attaching some velocity stacks to those carbs, possibly with some pod filters on the ends, but maybe that's just me.
i couldnt help but to notice the radio flyer wagon in the backround but you should make a trailer for the rat rod wagon!!
It's crazy how you guys are just so non shalant about buying all these mods and projects. From the looks of it you come $$$$$. Looks fun, maybe when I win the lottery i can move next door..lol
u need a fuel pump from a twin snowmobile intend of using a "T" splitter.
just my 2 cents
*instead
Have y'all thought about adding independent front suspension? I'm sure those wheelies are rough landing and can cause you to turn suddenly, maybe some shocks added to the front to support the fall?
Hi guys, love the videos. Im no expert but my brother in law races carts with either honda clones or predator 212's and they pretty much tape off 90% of cooling vents. Most of the vet racers run there 212's around 400 degrees so tape it up lol and may i suggest a pocket friendly cam upgrade sold by Gopowersports and ARC, the BSP-3, just a suggestion.
look up vacuum synchronizing multi carb motorcycles. you need to do that with your 670 it'll run a lot better. but good job guys!
To John: I think, using a pipe with a ratchet is a way to brake the ratchet, I would use a t-handle to break the thread (or a bolt =) ) and then - the ratchet.
Save the ratchet. Kill the bolt. Always cheaper. =)
doesn't matter if it's a kobalt or craftsman.
Have they never heard of a breaker bar?
+Damien Beltrami they don't have hex sockets either, so?
it's called using the right tool for the job, and it's smart and usually pays off in the end.
Damn! You guys did an awesome job!
thanks
4:50 I laughed way too much at this
You guys are a trip! Thanks for the entertaining videos.
That thing sounds great
i saw a wagon in the background you should make it into a drift cart i think that would be sick
Nice steering wheel broskis
Shouldn't the intake runners be longer? Maybe you could calculate the optimal intake length for the RPMs this thing turns and add some intake stacks to reach this length.
cool work guys ......
Think I would have rather had the simplicity of the single carb. Really, as rounded as the corners in the intake manifold are, I doubt your losing enough power to notice. Would also lengthen the chassis a bit so you aren't so knotted up to drive the thing. Really liking the exhaust note now. Not so sharp sounding. Damn cool rig guys!
Great job on the dual carb. setup ; BUT - the intake manifolds just "appear" on the engine in the video . How exactly did you make/construct those ??
actually I put a muffler on my box stock clone to add back pressure. it helps it run a little better on small engines but on a v twin I have noticed no difference in power just a little off the start but nothing at the end of the straight away.
Dual carbs might hurt your performance. The intake pulses on 1-2 cylinder engines cause them to turn on and shut off the fuel flow too quickly. A better carb would be a slightly larger than you need motorcycle carb jetted to run properly on your engine. You can read the plugs to find the right air/fuel mixture. Feed it with one of those small, cheap 5 psi electric fuel pumps and regulators. Around 1-2 psi of fuel pressure should be sufficient. Experiment with intake length to get the best balance of low and top end performance. Tie your exhaust tubes together with a tube of slightly smaller diameter to smooth out the exhaust pulses and provide better scavenging.
"Ike, i don't think we have the nuts to take out that bolt" ... "What are you talking about boy?" had me dying of laughter :')
"I don't think we have the nuts to take out that bolt...But I do have a solid rod."
@@BigMuddyCountry hahahaha.
Hey! You guys ever get into drones ? You could do something with them, like have it follow you, but only in open areas.
love your guys channel i want to start a build with your guys help and suggestion .
Dual air filters would look sick
i think i found what my next hobby is going to be. thanks.
'All rod and no nuts with a flat battery' not a way to impress da laydee's, hahahaha
Keep up the 'fine' work y'all ;0)
that so cool twin carbs like that thats a bad ass cart but not to be a jackoff please shortin the pipes it would look so much better im still with you guys really cool 55 or 60 mph is my bet
