I have a 94 GSR with 140k miles on it and When i first got it I did a compression test on it and Every cylnder was 230psi even. I have recently tested it again and got to thinking that I have never seen a motor with my milage and my compression... So I think it may have been rebuilt what are your guys thoughts on this?

PS: yes I am doing the compression test correctly.

why rebuild it...most likley cause is carbon build up carbon build up will increase compression if its on the dome or in the combustion chamber...u can try a top engine cleaner..but i would just leave it...dont rebuild a good motor

 

Im not saying i want to rebuild it....

What i said was do you think it has been rebuilt in the past...

Hmm ... it may not have been rebuilt. Mine had similiar results at 110K ... it is a 95. I know for the fact that it hasn't been rebuilt.
