Hi everyone I have a 94 storm with a 861cc wiesco bore kit in it now. It runs out well but I was told that I can press in the 650cc sleeves out of a kawasaki jetski and use the pistons too. It is suppose to be a wild setup. Can anyone help me out on this idea. Have any of you done this same thing??? Please any info on the parts needed and the performance of this setup is greatly appreciated. If this is suppose to fit in and work I am going to do it. Thanks in advance Grandad.
