Maybe thats why it dosent die when i take ignition Wire off in cylinder 4 every other did
GPZ900R manual gives a usable range between 9.4...14.5 kp/cm2 (133.7...206.2 psi) so I'd say #4 is critical and worn out, #3 is still okay but on the way to #4 => overhaulin' should be done soon.
BTW: compression test should be done when engine is warm (not hot to burn your fingers) and throttle full open!

I'd do another compression test. Make sure you take the air cleaner out and leave the lid off the air box. Also remember to have the throttle wide open.
