I have a track go kart, nice little 100cc, never had the chance to fniish building it and tune it up though. When tuned they can usually manage 0-60 in 4.5 seconds and a top sped of 80mph.
It looks like this without the plastics at the moment
If anyone would like to come have a go or help tune/build it then your more than welcome.
I'll have a tow bar fitted soon so I can take it to a track and really open it up.
