Default Compression test results

Me and my buddy just got finished doing a compression test on my 95 gsr with 104k on it. Cylinder 1 was 202, #2 was 206, #3 was 202 and #4 was 205. We dident disable the fuel system or block the throttle wide open like some manuals say, does this stuff really matter? We dident know how many times to crank it so we cranked it 12 or 13 times per cylinder, is that allright? The number went up fast on each cylinder then leveled out around 200 but was still going up slowly right before we stopped, should we of kept cranking until the number compleatly stopped going up all together?

Take out the ECU fuse. While cranking, stand on the gas pedal to hold it at WOT. YOU MUST DO THESE FOR ACCURATE RESULTS

well you need to do a test correctly because that way you really know what the test reads instead of something that might be inaccurate

Dude, you have to redo the test correctly before we can assess the condition of your motor.
