To Frank: thanks for your interest. No I haven't tested yet the Kawasaki plug hole change, meaning none of the engines in which I had the change implemented has started, but I requested this change be implemented  in a Mazda 13B, a Sachs KC-27, a Sachs KM-48, a Sachs KM-914, and one OMC 45 HP, just it have not started to turn yet, as installation in a car is pending.

It could be remarked, however, that from the K Yamamoto book, 1981 edition, charts of pressure differences from advanced chamber to the one behind, the pressures in the plug hole region are almost identical in both chambers, a SAE paper, 921444 by Marcos Langeani, of Chile, is about a RCE with high pressure recirculation of burned gases, towards the chamber behind.

So, I expect no losses from leaks, if I ever succeed in having the engines running, besides this, I have no means to measure output of engine, just the basic emissions parameters with the help of the type of probe that repair shops put in the exhaust tubes of cars.

have a good year 2017, + Salut
