    stock compression ratio on a 1982 gs 1100 gl?

    What is the stock compression ratio on a 1982 gs 1100 gl? I have a clymer manual but it says nothing about the compression ratio. Thanks in advance.

    Stock Compression ratio

    It is 9:5:1. This information came from the factory service manual.

      I'm not certain on the ratio, but I believe it is about 9.5 to 1.

      There is a formula for determining it, but you need the exact internal engine measurements, including all clearances.

      If you can settle for an approximation, check your engine compression in pounds per square inch and divide by 14.7.
