    83 Katana 750 Top End Swap to 1100

    A freind has a 83 Katana gsx 750, I seem to remember hearing that he could swap the top end with an 1100 e or 1150gs motor. Can anyone help me understand the options to upgrade the motor on this bike? Thanks, Kevin

    The 750 stroke is a LOT shorter so you have to mill the block to get the deck height correct. You also have to bore the upper case half so the 1100 sleeves will fit. Then you still have the 750 plain bearing crank & rods which are NOTORIOUS for oiling issues & bearing failures. The 1100 engine swap is a MUCH better idea. Ray.
