Volume check

The last part of the combustion chamber modification is to measure and equalize the volumes.  The target volume was 80cc which will yield a compression ratio of 10.0:1.  The right cylinder head measured at 79.9cc while the left head came in at 78cc and so needed some adjustment to be equal to the right head.

That's it for the combustion chamber modifications.  Next will be the port work, which I will detail here.  Here are the finished chambers.
