    Does it run "good", but indicate low compression? May have a bad gauge-- a friend purchased 2 compression testers, 1 for me and 1 for himself. We tested both on 1 of my skis and one would read 80 psi and using the other gauge would read 170 psi. The 1 reading low was incorrect by a large margin and was taken back to the store.

    have you possibly done a leak down test? or taking the heads off to have a look in the cylinders? to see if you can see everything..just because its has a new top end, does not mean it was put together correctly, rings could be bad, who knows, id suggest taking the domes off and having a look
