Hello everyone this is my first posting. I have a 1977 max iv with a chaparral 454cc two stroke. We replaced a lot of parts and the machine runs like a beast. The problem I have is it has 21x11x8 tires and it rides like a tank and no ground clearance. I would like to buy new rims and tires in 26x12x12 there seems to be enough clearance under the tub to fit them but I’m not sure. Can anyone help me on this.
