Recently the crankshaft and con rods of gsxr 750 K7 engine that was used for racing blew up. I'm unable to find a K7 crank for a reliable price, however I've seen that many ads have a fitment range from 06-20. Could there be a possibility that the newer crankshafts(11-20) fit in the older 06-07 model blocks? Generally looking for answers from someone who has worked on both of these engines before and know some answers
