Compression question
Those are the readings from the 3 faces of one rotor, and those numbers indicate that the combustion chamber tested is virtually new. Those are very good compression readings, just hope that the other rotor is as good.
damn those are really good compression numbers man, the highest is 9, man i hit 6.7 on the front rotor and on the rear 0-0-4.7. I'm just curious how many miles are on that motor?

and to test both rotors you put the compression tester in the front and back lower spark plug chambers right?

Thats a bit strange.
The faceplate says the unit of measure is x10 KPA.
kPa x 0.14504 = psi
So 90 x 0.14504 = 13.0536 PSI.
That alone confused me.
Another consideration is a genuine comp tester reads in kg/cm2 (bar). So it would be misleading to compare numbers off this meter with numbers off a genuine meter.

Move the decimal point to the right. 1kPa = ~ 14.5 psi.
