I`ve just orderd a 50 cc burette and im going to work out my CR and was wondering how many other people have done this and what results did they get.
Im going to work out the standard CR on an aby before i do any modifications and i have calculated a theoretical combustion chamber of 43cc`s using this tool

to save time.
Using feeler gauges i worked out the the steel head gasket was 1.55mm thick and used a -4cc dish for the standard pistons (bit of a guess there) to work out a 9.1CR.
