The chassis is a phantom nemesis chassis, I bought it used and it looks to be in great shape as everything else was immaculate... the seat was already mounted in the kart, all I did was slide it forward 1/2 inch or so to help with pedal length .. the seat is not much more then that off the bottom of the tube. I will check the length to the axle. I am greatly appreciating all the help and it seems there is a lot more to these karts then meets the eye... thank you guys for the help and I’m trying to be as helpful as I can.
