91 hp?

[ihavelikethree]

I am new to go kart building and my friend found a 91 hp motorcycle engine. I dont know if this will even work. Will i be able to use this engine in my go kart? Because it is so powerful, what parts are necessary transmission wise?

specs.

its generally called a gixxer kart. ull need a motorcycle sprocket and a hub strong enought to handle the torque

awesome. that means it will work? what do you recommend

gixxer kart is the term given to a kart with a suzuki gsxr engine(the motorbike the engine comes from is nicknamed a gixxer). You can put any motorbike engine in a kart, you will just need to beef everything up alot, you will need a super strong axle and hubs, high speed bearings back and front, a sprocket that uses the same kind of chain as the engine. It will be hell fast, should be fun haha

Check out this site: Motokarts.com, it's all about bigger bike engine karts, you can find some good ideas about what's needed and what other people have used successfully there.

cool. thanks. I am only worried about some aerodynamics. will i need to add lots of weight to make sure i dont go flying out of control?

It all really depends on gearing, and the type of kart your building. 91hp is quite a bit (im jealous my kart will only have 36 when shes done haha), but definitely not too much, theres no such thing. I doubt you will instantly lose control once you hit the gas, but you may have to go easy accelerating.

i was mostly worried about the slim possibility that my cart will be too light and be picked off the ground. maybe im just paranoid.

also, i am going to need a solid frame. My friend was thinkin about buying a used go kart and swapping the engines. i would think that a lot of the parts would have to be changed out. What should i do? i am not the best welder.

If it's gonna be a race type kart, and you're not good at welding and fabricating, you'll be better off to find a used 125cc shifter kart with no motor and modify it from there. It will already have the front brakes, a 50mm rear axle, 3 or 4 axle bearings, and the stiffest frame that's commonly used.

A used 125 shifter kart would end up handling, stopping and just generally holding up to the stress way better than the average fun/yard type kart.

I doubt youll lift off the ground till about 120mph or so. but youll probrobly need some downforce just for more traction
