Can anyone please give me any information on these racing kart frames? I received several from a deceased uncle that was big into racing, I know nothing about racing karts, and I’m trying to put it back together from the parts, in boxes, apparently he love to take everything apart and then couldn’t figure out how to put it back together, he would just go buy another kart, and put them in storage! So the one has 161 marked on the left side and I think someone told me it was a shifter cart has a KT 100 on it. Thank you for anybody’s help greatl Myy appreciated!
