    3 wheel go kart design for under $300 x4 (or more)

    haha ok you guys convinced me not to use the wheel barrow wheels, at the moment we just stumbled upon a bunch of awesome deals on craigslist and we're now planning to take those and fix em up, for instance the one i'm getting for $200 (minus bartering) is 4 wheeled and running with a brigg and...

    60cc chainsaw engine vs. predator 99cc on mini bike

    hmm alright, well it uses #40 chain from the engine to the jack shaft, and then its bike chain from the jack shaft to rear wheel. so if i want to replace my rear cassette with a single large sprocket, how could i do that? i have one from the original drive pedal that i could reuse, i think its...

    3 wheel go kart design for under $300 x4 (or more)

    true... the treads feel a little foamy... shoot, would just a higher quality wheel like this hold up? or does it have to be a go kart wheel?

    3 wheel go kart design for under $300 x4 (or more)

    whew... $60 just for the wheel... in my opinion replacing $6 wheels works out better for price. i have to convince a bunch of almost broke 18 year old guys to do this with me lol... ;) eventually i'll upgrade to something like that though. really i need to figure out a place that i'm going to...

    3 wheel go kart design for under $300 x4 (or more)

    ok so 16ga steel, got it. i posted the diagrams if it helps, the wheel hubs have 4 holes already drilled in them and they have a dual bearing set up, they are the cheap 10" wheels from harbor freight. the front two wheels are going to be set really wide, maybe 4' as opposed to less then 2'...

    hello everybody!

    yes i do indeed! its based on the spider carts scorpion 3 wheel design, i want to go with the 3 wheel for a couple reasons, mostly because i've devised a plan to make it much cheaper, and probably put us under the $300 mark. heres a link to my post about it in the go kart forum...

    60cc chainsaw engine vs. predator 99cc on mini bike

    the engine has a 12t on it, which goes to a 60t which on a jackshaft as you guys call it, turns a 10t which runs to the rear cassette. and the largest gear on the cassette is a 24t i'm pretty sure, or very close to that. the wheel is approx. 26" i know i'm in the ball park for ratios, i'm just...

    60cc chainsaw engine vs. predator 99cc on mini bike

    hmmm... alright, so is it better to just go with one gear rather then having 7? there is a compound gear in there, where the motor runs to a 60t that is on the same shaft as a 10t that goes back to the rear set, sorry if that wasn't clear... but that should be getting me into the ball park...

    cheap go kart build: the engine and clutch

    we are using the school tech lab (entire machine lab and welding available to us, and most importantly, the teacher said we could use it and she'd be willing to help) we're building virtually everything from stock steel to cut down the price, also my 3 wheel design cuts out almost everything...
