Z1000 A1 - Piston ring float querie

[David32knyte]

Hi All
Does anyone know what is an acceptable vertical (Up & down) movement for piston rings on standard ART pistons on Z1000 A1?

Also the vertical height of the slots?

Thanks

David

Groove widths
Top 1.23 - 1.25 mm (service limit 1.33 mm)
2nd 1.22 - 1.24 mm (service limit 1.32 mm)
Oil 2.51 - 2.53 mm (service limit 2.60 mm)

Thanks for the numbers.
Fingers crossed! (Certainly seemed more play than that when I wiggled it up and down)
