Thinking of build a gokart, suggestions?

[TehChikenHater]

I'm planning on building a go-kart over the winter, having it completed before Spring. What are some good suggestions? I have a couple of questions, so answer the following first, and then give some suggestions, please, and thank you!

What type of metal? (Cheap, Durable, and Light, do not say Aluminum, as I do not own an Arc-Welder, and I am not looking into paying 300$ for one from Home-Depot)
What is a good length? (From back to front)
What is a good width? (Left side to right side)
What is a good height? (From ground to chassis)
Is this a good motor? It's 49cc, so I do not need a license for it.

Where can I find 4 good tires under 75$.

EDIT: I weigh in at around 110 pounds. Would this motor push me, and the 25+ pounds of metal going into my kart? (Assuming go-kart metal all adds up to 25+)

Would this be a better motor? Seems like it would. :\

Welcome to the forum. You're going to be best served taking some time to cruise the forum for ideas here. There's tons to draw from.

Next, you need to make a decision on an overall design. If this is your first build, I suggest a basic, ladder-frame fun kart type.

For most go karts, 49cc is nowhere near enough. Commonly, we use 5-6.5hp. I don't know what the laws are around you, but in most places go karts are illegal on public streets whether you're powered by a 25cc Weedwhacker, or a big-block V8.

Narrow down your choices, then we can advise you more accurately.

Okay, thanks. Any suggestions on which metal to use?

For a small kart, 1" 16ga tube will be fine; round or square, your choice

@Fabroman,

Thank you very much! Steel, correct?

 

[Orange Krate]

Okay, thanks. Any suggestions on which metal to use?

Yes, steel. Chrome molly if your wallet's fat, otherwise hot rolled mild steel. If you've one near, try using Metal Supermarkets for a good price on small quantities.

BTW, what's "teh" story on your screen name? Are you a fan of Jay Farrar?

How long is a piece of string? As long as you need it to be...

As toystory suggested, have a good look through the forum & even the internet for ideas, thinking about what you want your kart to do & where you intend to ride it.

Once you've narrowed down your choices, we can talk about dimensions...

and the 25+ pounds of metal going into my kart? (Assuming go-kart metal all adds up to 25+)

Oh, it's gonna be a lot more than 25 pounds

As said before, I wouldn't suggest to use that 49cc 2 stroke engine. I have bad experience with this. It brakes down very fast + it won't have enough power to power your gokart.

I suggest to use a Predator engine from http://www.harborfreight.com/. I've heard great things about these engines.
