well,.....not a good day today with the GX5R, flame outs all day!! smoke'in plugs all days, put the OS speed in and snapped a conrod

, dint have a extra rod for the OS, so measured up and compared the two, and hmmm..........threw a GO GX5R conrod in the OS SPEED and ran perfect all day, so if any one tells you the GO rod does not fit the OS speed, they are lying
