Hi...  I have a while ago converted my dashboard from standard factory to all bright n fancy Chinese tat digital,  and now bored to death with it not working properly, and want to revert back to an old school style,  which does not use sensors but a rotor cable which plugs in the back of the Speedo,  noticed in Haynes the yzf has one that screws in on the wheel but it's very vague for the fzs (2002/3).... could someone plz help me out..... thanks

My 1991 XJ600 has a cable speedo driven from the front wheel

 

Wheel here - including gear assembly Fowlers parts for Pre Div XJ600 wheel

Cables here (though Wemoto cable just as good and cheaper)  Bars and Cable

Clocks here (though either discontinued or prohibitively expensive - try a breaker) Meter

Good luck in your quest

 

Just put the one you took off back on?
