Homemade Racing Go Kart (Shifter Kart Frame) Build

Here's our built from scratch go kart with homemade shifter kart frame with some home depot pipe and a harbor freight welder. We put a lot of time into this project and took a lot of pictures so we figured it would be cool to put it into a video. Kart has a predator 212cc motor with a comet torque converter and 11x6.00-6 Maxxis Tires on it. Top speed is around 45.

Great home build. You're lucky your dad helped you with it, seems like you guys bond well together unlike me and my old man. We've never done anything like this together. Can't wait till my kids are old enough to do stuff like this.

[@calikarts909]

hey, thinking of building something like that do you mind giving me the measurements?

[@KartFab]

haha sweet, i love the part where you ran into the garage. if the video gets 600,000 views, it will have paid for the damage lmao

[@BuildBreakRepeat]

KartFab Haha awesome man, just to let you know your videos of your orange kart helped us out a lot, you can see we copied the gas and brake pedal design of it lol.

Can you pass the measurements??

[@JohnWilliams-nx2no]

this whole thing is perfect. love how the dent from the "test run" shows up so great after paint! :D build break repeat is a well chosen name

[@BuildBreakRepeat]

Haha yeah, we were debating whether or not to pull out that dent but now I'm glad we left it.

[@WWMike12]

Woah! Absolutely appreciate the enthusiasm! Just a few things to consider in your design 1: you've got very little positive caster in your design. It provides more front-end grip as well transfers load to the front when turning. Steering efforts increased, but helps straight-line stability, and 2: Ackerman! Right now, when turning, your front wheels are following the same radius around a given corner. This works against you in that the inside wheel is going through heavy scrubbing, thereby inducing understeer. Yeah, so you've got two things that will promote understeer as you get close to the limit of your chassis. Lot's on it out there

[@BuildBreakRepeat]

michael green Thanks for the info, we have experienced some understeer so we'll look into it.

[@Captainkleen]

Very “Sweet” Go Cart and very well looking build. Now put a Mikuni V22 and put a 40 main jet you can always adjust the emulsion needle valve if it’s running rich put the clip at third from bottom and if it’s lean use the very last notch on the needle valve and you should notice a nice fast response on it. Nice job!!!

[@speedyhernandez320]

You guys may not read this, but I’m making my own go kart, and you guys are such a huge inspiration, and you really show me that this can be possible and fun to do, so thank you very much

[@JJiG]

if you want to succeed making youtube videos, don't ever film in portrait mode.

[@BuildBreakRepeat]

JJiG Yeah...at the time we were taking these pictures and stuff we didn't have a KZbin video in mind but in the future we will definitely avoid it because it's pretty cringe lol.

[@dannyzacharski5647]

Nice Job fellows, I have been a machinist for 40 years plus and I say Job well done! Enjoy it.

[@AstroTundraBASS]

I would have tied those 2 rear tubes together in the back, like a rear bumper or something. Improve stiffness

[@BuildBreakRepeat]

TundraBass954 Yeah we were considering it but the axle does a pretty good job stiffening it up in the back. But if we do it again we'll probably add something like that, thanks for the input.

[@littletree05]

Where did order your axle from and how much ?

[@tjrn4203]

frame needs flex torsion bar would be better

[@jojoreallifeshow8187]

Huge accomplishment..Set out for your dreams with the same effort you put in that go kart

[@franklinvenneers51]

it really would have been a good series i love the build

[@carolinawestern3875]

Using a 550cc.4 carb/stroke engine From a 75 Kawasaki CB550. On a small dune buggy. Moving the hand to foot throttle. Left bar tube & clutch to a pivot shifter by the seat. Dual 2 in 1 open exhaust resonators. It was scary fast & so powerful, it bent the stock axle shaft!

[@mattpeirce2635]

What was the total price for all the metal for the frame build

[@joeshmo2473]

Thats the same thing I asked. It would be nice to know man

[@jamesarmstrong-jones5082]

@@joeshmo2473 probably $40

[@austinreap7027]

nice build guys

[@mightress]

if you want it to steer better, switch the spindles. you have them mounted left/right switched. steering arms should be behind the axle

[@alexanderraccuia7232]

Do you know the diameter of the tubing that you used in the build?

One hell of a scratch built kart boys. Especially for a first time

[@billbaggins9961]

Great job fella's, I'm sure the BUG has hit you now and you're already planning a different design so learn what you can from each and every part you build and enjoy what you do because it could lead you into a career of fabricating or maybe just the hobby of it but either way there is nothing better than being able to build what you desire.

[@shawnadams5202]

That’s a good way to test your welds 🤣

[@vitor900000]

[@BuildBreakRepeat]

Vitor Leão Those pics were from after we hit the house, we had brakes at that time too lol, it was the only semi complete pics I had of the kart do I just threw them in haha. So yeah in the vid you can see him look for the kill switch on the engine but then he just gives up.....another thing that would be nice to have before we test drove it lol.

[@benedictpostma306]

Do you have any plans or measurements, I really like the design

[@ValeRocks]

Nice project Guys!!

[@mikeroberts7775]

You guys did an excellent job and you should be proud of it. Now a few comments about kart racing. Racing karts are governed by the FIA the same people that govern F1 and a myriad of other types and classes of racing cars. Because of this the chassis must conform to exact specifications length, width, distance between axels and on and on. Your understeer problem may be solved by moving the front wheels in as far out as you can on the spindles and moving your rear wheels in. Also it looks as if you are using the same size tires on all corners. The front tires should be smaller than the rears. You may also want to run less pressure on the fronts. I think the biggest issue you are facing with concern to under steer is the frame design. Specifically the castor of the front wheels. You will notice that if you turn the steering wheel on a racing kart it will make the back wheel lift off the ground a fraction. Turn the steering wheel to the left it will pick up the left hand back wheel. This acts as a differential because the inside rear tire will want to turn faster than the outside. If a rear wheel is not lifted the the locked up rear axel will want to push the cart straight and there is your understeer. Racing carts also have removable chassis components one behind the seat the other along the side of the driver these act to make the chassis rigid or more flexible. I could go on and on so you can imagine what it is like to set up a racing kart at different tracks it is a lot of work and is not dissimilar to setting up an F3, F2 or even an fi one car. Once again i think you did a superb job at your first go it is something that i would never attempt. I hope this info helps try looking at the CRG website or First kart. If you need more setup info i would be happy to help.

[@BuildBreakRepeat]

Mike Roberts Dang man you know your stuff. Thanks for the input, we really need to adjust our front caster like you stated.

[@bookooc]

Well he doesn't know everything. FIA has little to do with most karting in the USA. There are several organizations that govern Karting here. IKF (International Kart Federation), WKA (World Karting Association), KART (Karters of America Racing Triad), USPKS (United States Pro Karting Series)

[@mikeroberts7775]

Sorry guys if you look at the layout of their tube chassis it is a direct copy of a world championship kart. All world championship karts are governed by the FIA. I did a lot of SKUSA racing in Las Vegas and raced for FIRST KART all of the privateers that used first kart chassis were exactly the same as the factory team ones just one level behind. When Schumacher was making his comeback he raced icc all over the world i realize it is now called KZ. Of course there are lots of different types of racing but what these guys are building closely resembles a world championship kart not a dirt track chewing tobacco league. Don’t be such a pedantic twit NONYA

[@L3thal69]

45km or mph? And how much was the overall cost in usd

[@seandemeritt3947]

I wanted to make go kart very similar to this one but i was wondering about the best way to raise the clearance of the back half of the cart.

[@BuildBreakRepeat]

sean demeritt Well if you wanted to raise it a lot then you could weld the bearing retainers on the bottom side of the frame, but if you wanted it to just be a little bit higher you could grind down the bottom of the retainer a little bit.

[@pvanb291]

An interesting project, but you called it a "Racing" gokart. Do you guys in USA have a class that slow to race something like this??? In NZ, I was racing a "slow" (compared to circuit karts) grass kart. Suzuki RM 250 water-cooled 2 stroke, with 5 speed gearbox and computer programmable CDI, with 9500 rpm limiter and a flat-shift input. Really quick through the gears and a top speed of around 110 kmh or 70 mph.

[@BuildBreakRepeat]

Peter van Brucken No definitely not, I just was referring to the frame but that racing you do sounds sick, yeah but not anything close to what this is lol.

[@rsz90182]

An afterthought, what if he turned the steering wheel and began doing donuts until you found the kill switch?

[@racekartrental2673]

would be awesome to develop this kart on a track. 👍🏻. Get a Mychron lap timer to see your fastest lap times & to monitor engine RPM which if you removed the governor on that Predator Engine the max safe RPM is 5000RPM according to a few resources. That engine becomes very dangerous after that RPM bcuz the flywheel literally explodes due to it being made out of cheap chinese cast metal. Please do your research on this fact. 🙏🏻. After you have dialed in your max rpm start working with tire temps & pressures. A pyrometer is a must in that the tire temps should be as even as possible on 3 points on the contact patch of the tire, the outside,middle, and inside. That should get you started. Hope it goes well!
