No expert on thiese particular bikes but what I did notice is that the FZS and YZF models are covered in a single Haynes manual; might give a clue
Sure, the two engines have some components in common, but since the cylinder head is obviously not one of them it seems likely that the cam chain could be a different length.

FZS I presume can't be split, thus different part number. the good news I would say if you have a split link type already then you can atleast fit and try with minimal work
