High Compression?

[worr12345]

I am looking at purchasing a 95 2g GSX with 125K. The owner says the car doesn't smoke at all or burn anything, which is good. I asked for a compression test, and they came out with 180-185-170-175 . I know stock compression for a 2G is 175, but the higher compression for cylinder 4 and 3 bother me some, and the 15psi difference between 3 and 2. I am thinking about asking them to a wet test to see how the rings are doing. I just wanted to ask if these numbers look good on such a high milege motor, and if it is probably the rings showing the high compression and there age. Thanks..

Higher compression is a result of carbon buildup. Piston rings should not develop greater compression as the miles increase, only decrease due to wear.
