Engine buiding processing slowly

Heads were lying on the garage table about three months... Finally I got myself going and with a little help from my friend we machined 1mm from the heads allowing decrease the capacity from 62cc to 56cc, so this way I can set the compression ratio with 1-1,5mm deck height near 9:1. Video from the action.

My brand new 044 and trial 1300cc heads on the background.



This neat tool to milling machine allows not only radial milling, but planing of the bottom too, as it is radially adjustable.



From 1300cc to 1600cc.





Comparing the result, the finish from the tool is better that original from the producer of the heads.
