650/X-2 650 compression

going to look at another ski tonight, what should the compression be in one of these motors?

I think anywhere from 155-165 is ok. More important is that the two cylinders are equal or very close to equal in compression.

I say 140 and up as long as there within 5psi from each other been riding my wifes with 130psi in both for the past year with no problems

it had like 150, just now have to fig out the spark issue. the elec box at the coil was full of water when i unbolted it. the ski is an 88
