I have caried out a compression test on a Z 1000 st E2, it has new valves and the barrels have been honed with new rings. No:1 shows 160psi No:2 133. No:3 140 and No: 4 145 psi. Is these reading what i should expect or are they too far out from one another.

You need to put some miles on it then retest

I believe the 120PSI is the minimum and no more than 20PSI between them.
If it's not been run since the hone, ten as suggested, give it some mile and recheck.
