Goodafternoon. Does anybody know the float height setting of my GPZ 1000 RX / ZX1000 A. from 1986? My dutch translated manual gives me 17mm, but since it doesn't get any fuel now at all, I don't trust this 17mm anymore.Thanks, Frank from the netherlands

17 is correct Frank mesured from the base of the carburetor. Meaning the flat surface that the bowl bolts to, from the part of the float furthest away. With the needle just touching the seat.
If you have set this correctly and are not getting fuel the next thing to check is that the needle and seat are not binding with a bit of grit (rarely happens) or that there is a problem with the petcock or filter. If it is vacume operated try sucking the vacume tume and see if fuel runs out of the hose into a container at a decent flow rate. If not vacume operated check the flow into a container when the tap is turned on. lastly check the fuel line does not have a kink or collapse caused by inferior line type or sharp bend.
Hope you get it going soon mate.
