The flat tops or the high comp ones with the crown?

yes it is an electric water pump . used DIAHATSU applause pistons 77mm .

Again like everyone says this is very cool.

Knowing the the combustion chambers are 39cc what did you do to up the compression?

Also am I correct in that you are using a electric water pump?

Finally I'd bet you could sell the basic plans...........I'd pay up to know the details.

Very cool, hats off to you sir!

edit: Ive lost sleep since this was revealed!

Can you tell us the belt you used and the crank modifications to the snouth?
its looks like the alloy plate you used would be contoured on the inside to match the casting of the timing case cavity etc?

Finished product was already posted earlier, Im interested in the bores, water and oil gallery mods etc. Did you offset bore for the equal spacing of the head and are there any pics to show the mods for water and oil?
Really nice of you to post your pioneering efforts, the first to succeed in converting and running such an ingenious setup.
