Hi Paul,
Pictures of a few frames I bought that I have buit up using parts supplied by Cut Price Racing. Seriously considering converting one of the karts to a twin engine machine.

My kids are currently using three karts to race around a loop trhat has been marked out around our house. My wife is very much over us tearing up all of the lawn around the house - imagine the damage we could do with two engines!

Two photos are of one of the karts that I am hoping convert, and the third photo is of our backyard racing (complete with 50s also)
