2 stroke 72cc kart?

[SpeedEng]

been thinking about building a kart for years (just never got off my lazy butt to do it lol)

I have a spare
Aprilia (2 stroke) 50cc (72cc metrakit big bore ~14hp liquid cooled)
mated with a 6 speed tranny
with my bikes old stock pipe

any one have plans for a shifter cart (on road/street plans)
or any info on how I should start?

Thanks

Start by drawing up your kart design. And then posting it, and then we'll critique it! :)
