hey dudes how goes it? yea im new to this site but i need some help. im goin to college for mechanical design and im turning a 1994 honda 300ex fourwheeler into an offroad go kart. as of right now i just need to find out where i can order an axel that can take a 300cc engine. so if you could point me out to a website that i can order off of that would be awesome. i was going to use the rear end of the fourwheeler but its way to narrow so. idk i jst need a couple pointers thanx.

Get a 1" solid keyed axle from a go kart parts website.

ehh.. you going suspended or not? planning to be airborn or not? if you jump on a 1" axle no suspension, it won't hold up. it may be ok for a road/not airborn ride, but you really need suspension to keep it from bending, if I bend the one I'm using now, I'm getting 1" drill rod and welding the accessory's to it. I used this for the jack shaft and it is SOOOOO much stronger than the stuff they sell for axles. you could always use really floaty tires.
i will probably never go airborne. but i will be goin off road like through wooded areas that are rocky. um i still have the single shock from the rear end of my fourwheeler. i would like to be able to re use the hubs and the 6ply tires just for the fact that i can run about .5 lbs of air in them and that should give enough coushin for it if i keep it a solid rear end which is what i am aiming for. i would really like to keep it a solid rear end because of a time constraint on the project and adding suspension is just that much more time consuming. so i mean if you can point me out to a website that sells an axel that can support the stress from that 300cc that would be awesome. but i also want it to be a longer axel so i can widen this thing out because the width of that fourwheeler's rear end is just way to narrow and id prolly tip over all the time lol. so i think a 3ft long axel would to the trick and then my tires would obviously add width but idk. but yea dude thnx for the response and i hope to hear from you again cuz i seriously need som help findin an axel.

well most 3 wheelers/4wheelers have a stepped axle, you'd need to know the shaft size at the hub to be able to use those, but they are probably standard 4x4 8", if they are, you could buy 2 steel (not cast) trailer hubs, and weld the bearing races to a tube of just about whatever you can find hardened, solid or tube, that would be around 1 1/2, at that size you'd be hard pressed to bend a solid rod of anything, but drill steel is still what I'd use. 3ft of this cost me about 25 bucks in 1" I'd suspect it would be 30-40 bucks for it. thats what i'd do for no suspension, I'd risk it with suspension, but thats me. good luck with it.
if they are just 8" wheels, with some other, get some golfcart wheels so you can go to standard gokart wheel bolts, which will work with 4 bolt trailer and 4 bolt gocart parts.

hey thnx again but i jst have like one more question for now. um what do u think i should do about the throttle cable and the clutch cable? the stock ones on the fourwheeler are no where near long enough to reach where ill have the gas, clutch, and brake pedals? is there somewhere i can get longer cables?

Lord of the noise
See if you can find 4140 precision ground high tensile bar for your axle, it's the best bet. 1" or 1+1/4".
Most motorbike places will have universal cables which you can buy.

I used teflon coated SS bicycle brake cable designed for a tandem for my throttle, its holding up well, and the teflon keeps it slippery.
I used very heavy cables for my shifter, but I had to design a whole system around them, probably not what you want to do! you might consider setting up a solid rod extension, between two equal length pivots(think levers but being equal length they get you no leverage!), would be the cheapest way on something like a bike, using a stock length shifter cable to make it easily replaceable.
brakes, I can't help you there, I went lazy hydraulics, so I dunno, but the cables I used are big versions of this http://surpluscenter.com/item.asp?item=1-3071&catname=engines

i used something like this on my clutch (but its not a bike clutch, so you may have to adapt, might work for brakes, but VERY over beefy the first one I showed you is probably more the size you are looking for)

These are called push pull cables, and they are used for remote hydraulic controllers and etc on agriculture equipment, so if you are somewhere near a place that sells or services bulldozer, big farm equipment, etc, you can get them locally.
