Homemade Racing Go Kart (Shifter Kart Frame) Build

[@crites123456789]

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.

had an incredible time with this cart for near a year after i bought it. unfortunately had to sell it but with the time i had it it was a blast. incredible job guys

[@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.

[@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!!!

[@waderedsox]

nice work guys, i know from experience how annoying those harbor freight welders can be, getting the feeds right and trying not to burn through, you did a really good job

[@BuildBreakRepeat]

waderedsox Haha yeah, I've got a love hate relationship with harbor freight.

[@73macrino]

Without really doing measurements, it came out pretty good. Nice job 👌. Now to build another one with a 125cc so it will go straight through the garage door lol

[@BuildBreakRepeat]

M Cass Haha that actually made me laugh out loud.

[@73macrino]

[@BuildBreakRepeat]

M Cass Sick thx

[@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

[@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.

[@AlphaMachina]

Next time, if there is a next time (and there should be) because you'll only get better at it, especially putting all of this work in, you guys should make sure to measure, measure, measure. Draw out a perfectly measured grid on that sheetrock or whatever medium you use, and use the grid to get your two sides even. Then measure and mark directly onto the metal with permanent marker every single time you're going to weld a joint. Like that old saying "Measured once, cut twice, and the damn thing is still too short." :D

[@BuildBreakRepeat]

Alpha Machina lol yeah, good idea with the grid, what we really need to figure out is a way to make the bends equal because there isn't really any measurements or anything for that pipe bender, but yeah like you said hopefully we only get better haha.

[@k1ortia]

i think you,ll find thats measure twice cut once. easy mistake

[@H4CkGAMiNG712]

That is one baddddd looking kart. Hell yeah! The black accents really make the white stand out.

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

[@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.

You guys did a great job on this!

[@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!

[@rlspanky]

OUTSTANDING JOB. AM WAITING FOR THE NEXT VIDEO. GREAT JOB GOES OUT TO ALL THREE OF YOU GUY.

[@gusalmighty5098]

You should do some research on Ackerman steering geometry. Your steering will be improved 100% and your front tires will last twice as long. Your current set up steers your outside front wheel sharper than your inside front.......the exact opposite of how it should be. You might also consider adding some caster to your spindle brackets........your chassis looks really rigid so remounting the brackets with just a 10 degree tilt toward the rear will help straight line stability and create a jacking effect while turning that greatly reduces a karts tendency to push or understeer through turns.

[@jimmywilson1388]

Nice little kart!

[@l.t.keefer9310]

job well done, looks like had fun building it and sure you's will have plenty of fun breaking it 👍

[@littleconc5615]

Dude that is exactly what happened to me!! Me go cart took off across the into a brick wall, I was only nine then.

[@danteboretti5466]

Can you pass the measurements??

[@garrittpwl]

Eh, nice build, racing kart frames don't weld the floor pan in intentionally though :/

[@BuildBreakRepeat]

garrittpwl Yeah, we learned that after we did it....something we can take away for our next build.

[@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

[@Electobat]

Really nice job with that. You have a great approach to the engineering.

[@a_jegers]

Hahahaha same thing happened to me only we tightened the governor spring thinking it would pull the throttle closed better. Took off with no one in it, jumped the curb and went into my neighbors house.

[@vitor900000]

3:51 hey look a kill switch 7:30 completely forget about it and hit the garage door

[@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.

[@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.

[@yolovang2828]

Wow.....no brakes nothing and you guys turned it on without checking throttle or anything that was smart.

if you can find a used enclosed trailer that would work for a shop to work on it also i recommend watching some build vids and making a list of what you need to buy and you can find the parts and motor at harbor freight or tractor supply might have to get the body frame online or from a retired racer if you don’t know how to weld

[@suckthis1684]

Great job guys love those wheels

[@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
