Just checking a few details about the overbore kit ...
600 is 583cc = 80 bore and 57.8 stroke
620 is 618cc = 80 bore and 61.5 stroke
675 overbore on 620 = 83.5 bore (?) and 61.5 stroke
therefore overbore on 600 gives 83.5 bore and 57.8 stroke = 634cc
ie a full 675 upgrade to a 600 will require a new crank ?!
