I've decided to start another project for my 4yr old nephew.

Has anyone ever driven a 5bhp b&s go-kart?

I bought a used frame with 4 wheel drum brakes. I'm going to upgrade the brakes to 4w disks and some nice grippy tires. We also just ordered a new engine...

250cc V-twin 2cyl = 24.8bhp + 5spd manual transmission

In a 250lb chasis it'll run 75-85mph. In the go-kart it'll have a solid rear axle and plenty of grip. I'm just wondering if this will be prone to flipping over under heavy acceleration.


p.s. for those worried about the 4-5yr old driving it....We're not going to teach him how to shift gears! He'll be stuck in first so it'll just accelerate like a rocket until about 15mph or so.

 

oh yeah...if anyone else is interested in a project like this it can be had for VERY cheap.

go-kart chasis (no engine) = $45

brand new v-twin 250cc+ tranny = $210+85 shipping

new wheels/tires = $100

random tinkering/welding = $50.

 

Maybe not arrested but surely someone should have put you in a little white room by now...

Anyway, the project sounds fun, good luck with it. As for keeping the kid in 1st gear, good luck with that. I say it takes him less than three hours driving it before he figures it out himself.

 

he can't shift it if I dont install the shift lever!

 

good point.

Not sure I'd do it, but I hope you all have fun!

 

If the kart is not going to be shifted.
why not just put a one gear tran. in it?

 

because the engine cames with the trans already mounted together for $210....best deal I've seen on such an item

 

i wish you were my uncle!

you'd be screwed though if he gets smart, an finds a way to shift gears

 

nice, had a rac'n kart one time, cornered like it was on rails, guess it depends on how wide it is and how low it is? mine was about 1" off the ground with slicks on all 4's - hella phun.

 

where did you buy the engine and trans?
