Diverse browsing told me of the YEB-632 having a 0.768 bore.
That is considerably over the previously stated 0.689 bore of the YEB-631.
The 0.768 bore might be true, but I can not help wondering whether we are talking of the bore of the 3 first valves or of the 4th valve.
Any clarification available on-board?
