Well had a guy text me this morning saying he has either a 90,91 or 92 superjet for sale. It has the 650 motor in it and all it needs is a new coil. Everything is stock except for the paint job. He wants $200 for the ski. This seems like a really good deal but before i buy it what do i need to look out for with the ski? Also later down the road would i be able to put a 701 in this ski?
