a compression of 122 is good. Anything within 10% . I've seen sleds running fine with 90 lbs of compression. So dont worry, just use good oil and keep it running clean.

Yup, compresion testers(especially automotive ones)rarely agree with one another.

I have the 99 Arctic performance manual, THEY don't even give an actual numerical value, they say that within 10% of one another is ok.:)
