Default Anyone know where i can get some free go kart plans? Or give me some ideas...

Since there doesnt seem to be any real threads in this section haha.. I think this was the best place to post it. I am wanting to built a go kart over the summer. I want a full suspension one. If i cant find some plans i have an idea about the rear and ill just start from scratch and built it all myself but i would like some plans or something to help out. Anyone know of any? Or if you have some ideas about the front end as far as the steering and suspension..


I want it to be somewhat similar to this go kart but i want mine to be a bit more rugged or heavy duty or whatever you want to call it. Im planning doing the rear end like this one cuz it seems the easiest way.

I been thinking of using my 440 fan out of my older polaris but that engine isnt the greatest and its a single carb. I will use that if i have to but it would be harder. I want to find a dirt bike engine or something i think that would be alot easier.. I think i have most of the tubing to make the frame and stuff..

Maybe a little more similar to this one..

Actually i just thought of something. If i use a seld engine and clutches i could put a chain case on it too. Then i could change the gearing around if i wanted to. I can get a 340 fan with dual carbs for 125 bucks but doesnt come with a cdi. Maybe that would be a nice little engine for the go kart? Im thinking something a little bigger tho. Anyways what do you guys think is better? A sled engine with the clutches and chain case or a dirt bike or similer engine that would be easier.. Let me know your guys input.

I've seen a few with sled engines(clutches and chain drive) they worked pretty good. I also built one in high school, we used the engine/transmission/rear axle out of an old yamaha 4 wheeler, Would have worked better with clutches, but thats what we had.

As far as suspension goes. Get an A-arm front suspension (whole) out of an old ATV or new sled. That will make things very easy because all you have to do is weld the A arm mounts to your frame.

I like that idea with the front end. Ill have to see if i can find an old 4 wheeler for parts or something. After thinking about the clutches and chaincase i think i would rather use a sled engine but ill need to find that stuff cuz my old polaris sled doesnt even have a chain case haha.

Also do you have any ideas about the rear axle? Im thinking something like 4 wheeler rims and tires but i dont know how i would bolt those on as an axle form a wheeler would be too narrow i think, right?

You don't need a chain case, just a chain and sprockets, like what is on a dirtbike or ATV.

Rear axle you can use a solid bar that you can fit a sprocket onto, and then some way to mount tires, rear ATV tires work great. We used the stock ATV rear end so our kart was only about 4' wide, but once we were done with everything it was 8-10' long lol

Do you mean use the same sprockets like from a sled or should i get some other chain and sprockets? I guess i wouldnt need a chain case i dono why i was thinking i did haha.

ya i would like to throw some atv wheels on it. 8-10 feet long?? that sounds pretty long haha. Lets say i use an engine from a sled, i want to use the secondary clutch too right? Ill have the seconday clutch on a separate axle then the chain would drive the axle with the wheels on right? So it would be set up just like a sled.. Sorry its kinda hard to explain haha.

Ya i got the concept. Thanks for the idea for the front end. That will work out great if i can find an old atv. Hopefuly i can actually do this project.. I think i might just use my old 440 fan engine and clutches jus to get it up and going once its time and then once its ready ill prolly work more on the engine or find another. I want to put dual carbs and make it run a bit better. Well if i ever get it this thing started ill start a new thread with my project and how its coming along. Ill have to start making some plans or something to see what size and everything is gona be or ill just go by looks haha and throw everything together to my preference. I dono haha..

Sled Engine + Go-Kart frame = Bald tires, speed, and danger.

Well it may be a bit fast but im planning on using my older 440 fan for the engine. And it isnt the best runner, its a little hard to start but it runs ok. So its not like ill have a 600 triple or something on it haha.. I could change the gearing around too..

That 440 will put you at 100mph, with correct clutching and gearing. Believe me, I've done it.

Well im not going to try and clutch and gear it for that fast.. Maybe i will leave the single carb on it and make it easier too. What would be the difference if i added another carb?

The best part about having a go-kart is when you screaming down a raod and some old lady calls you in. Then the gas tank mounts break and it falls onto the throttle cable (pulling it tight) right as you are trying to stop in front of the Sheriff's truck

Haha is that what happened to you or what? I have a homemade go kart with no suspension that i used to drive on the road when i lived in an even smaller town and they called the cops on me 2 or 3 times when the neighbor drove his 3 wheeler and crap in the street..

yup, and because it was revving so high it wouldn't shift out, I ended up bending the brake pedal trying to get it to stay stopped

Do you think i would be happy with a 340 fan on it? For 125 bucks it comes with the primary and carbs but it needs a cdi.

Yes, the 340 fanner will do just fine. Think of the quads that are only 250cc.

If i ever get this project going i think ill use my 440 just to get it going and get it mounted and stuff.. And if i get a hold of the 340 it should bolt right into where i had the 440 right? IBS did you build a go kart too?

Hey power did you still have that go kart you made?

when you mount the engines the center-center belt distances might be off, so you'll have to be careful of that.

No I don't have it. It was a friend of mine that supplied the donor ATV so he kept it, not even sure if he still has it

I want to start the frame or something soon.. I was thinking about building the rear end where the motor sits first or would that be a bad idea? I think i would need to start the actual frame itself first right? This is gona be hard haha.. Does any on here have a go kart similar to the ones above that could give me some measurements so i can make it pretty similar to that?

The snowmobile had a specific C-C distance between the primary and secondary clutches. Use this same distance and you will be able to use the same belt.

It'll be easiest to make a 1 piece frame, so measure out where you want to put the engine and make the frame wide enough to accommodate that

If its a complete one piece frame i dont know how i would do the suspenion on the rear.. I want to make it similar to the go karts in the pics i posted, Doesnt that mean i need to make the rear end kind of a separate piece?
