What screws are you after?
Also, dunno, code is 00 L948
My '03 bike is 01 L296
As far as I'm aware the carbs never changed on the fzs
Previous owner of my bike buggered about with the carbs - split diaphragm in 4, and random collection of harware underneath (holding the float chamber on). If I can get a set of carbs cheap (really cheap), I might cannabalise diamphragms, harware etc to make 1 working set.
According to the Haynes book of lies, the fuel level changed by 10mm in 2000. No other change listed.
