What compression should I expect to see on a 1998 stock Evo 80 ci w/20,000 miles?

Hippo is the guy for that question and he has been scarce lately, as you know our site has been down, give it some more time, sorry brother.

these kind of question seem to bore the hippo.
i have a 94 flhtc with 100000 miles on it , the cyc pres was 130 lbs. and ran well with no smoking or excessive oil consumption.
had the base gaskets replaced at 103000 miles and new rings, compression now 150 lbs.
when checking be sure to open throttle wide open.
also can check out bikerheaven.com , they seem to have better response for older bikes.
