Cool compression test

I have an '85 750 with 17,500 miles. The compression test shows 125 psi in each cylinder. Is this good?

It is if you had the throttle closed or a cold motor.

Kawasaki spec is 129-199 lbs at 300 rpms. You are a little low.

If its an '85 US version, its a 700, not a 750....which in my opinion is a better engine (Im biased).....should be stamped by the bottom of the left side case.....should say "699cc"....
And that compression for something that old is great....my beat-to-heck 85 was getting around 115 rear, 110 front.....and I felt that was awesome....
