Pinhead,

It is often dificult to comment on other peoples 'experiments' as the full charactoristics of the engine can be pretty much an unkown.

I like the idea of the dimpled valves but the real question is - does the engine like the dimpled valves.

As for atomization/vaporization I am inclined to think that the dimples produce- by whatever means - more mechanical break up of any wet streams rather than just adding vapor capability due to extra heat transfer area.

In all I have not tried the dimpled valve deal but I just have a gut feeling it has sufficient merit to work.

As for the carb re-cal with much smaller jets I am not really sure what to think of that. It could be that a better combustion process is producing a better scavenge wave from the exhaust and thats the reason for the smaller jets but really - at this stage - who knows?
