last night me and a freind were talking about building our ghetto mini bike out of random **** and a bmx frame. for the motor we were thinking about using a 6.5hp go kart motor! 198cc **** a lil 49cc and for the throttle and brake were just gonna use break levers. left lever will be front break and the right lever will be gas, might incorporate a foot break too. for the back rim i've seen 10x3 mini bike rims which look pretty nice. the only thing is that im not too sure how the clutch system works on those go karts. i know its pretty simple i just have never messed with one. the main reason why i was thinking about this type of engine is that its fully self contained besides the controls. no battery, no wiring just gas and go.

what do you think top speed on this will be? a 5hp will make a go kart go around 20mph and thats heavier with les hp so i think the 6.5hp might be scary considering that i've seen a 49cc get up to 6mph.

i plan on doing all the welding with an old stick welder (stone age compared to most of yall...someone wanna donate a TIG ?)

any input or elaboration on ideas welcome

btw: i've also seen the DIY frame flange kits that sell on ebay any of yall used these?

 

ok i know its not the most original idea....but im bored and i think it will be fun

 

i'm sure you have probably already seen this but i thought it was pretty badass https://honda-tech.com/zerothread?id=1016669
