compression test numbers

just curious as to what compression number should be on bikes. im an auto tech so i know how to do it and whats important etc. but for bikes how many cycles should it take and what is average numbers? my 1.5 civic pushed 185 psi and only took about 2-3cycles. i did a check on my F4 and it pushed around 150-160psi but took a good 10 cycles or so. i figured cuz its only 600cc so its not moving that much air. let me know thanks

150-160 is within spec.
More important is that the numbers are close between all of the cylinders. I like within 5%.

ok so i got 125~ on the rear and 135~ front (tl1000r) . IMO i dont like the way this looks. based on my F4 i should have more. bigger motor/stroke/bore. little bit lower C/R 11.7 V.S. 12.0 but it should have balanced out with 1000 v2 vs. 600 i4

anyone have any input. nothing is really "wrong" with the bike, it runs great the last time i rode it feb '10 i just did it just cuz before i put it back together (paint etc...)
