Kawasaki GPX250(1995) compression test

Hi Guys,

I just did a compression test on my old Kawasaki GPX250(1995).
Bike wasn't running or doing anything before, but I somehow got it to crank and start.
It idles fine as long as I keep the petrol flow manually controlled or the carby floods and engine stops.

I warmed it up enough and did the compression test on both cylinders and it came up as 150 psi on both sides. while opening the throttle full.

I'm wondering if this is a good reading. I haven't road tested it yet, but the gears appear to be shifting fine on the center stand test. Bike has 57k+ on the odometer.

Any suggestions, advice, help, opinions about the compression reading would be great.
