not sure where you are going with this but the exhaust needs to open first to start to get the flow out it it were at the same level as the trans port the charge wouldn't know which way to go and would fill the motur.
on closing the exhaust port closes last which allows that expansion chamber super charge to reenter the combustion chamber.
I'm no expert by any means and my understanding could be wrong, it has happened before, just ask my wife
Adnoh seems to be on the same page as me on this one. He knows what I'm asking.
You stated: "but the exhaust needs to open first to start to get the flow out if it were at the same level as the trans port the charge wouldn't know which way to go and would fill the motur."
What I am saying is: "I want the entire exhaust port completely open BEFORE the transfer port opens". I want it all (transfer port) below the exhaust port.
So my question is: "Will this work and if not then why ?".
My reasoning is that is gives the max time for the exhaust to flow out and this high pressure suddenly evacuating the combustion chamber should cause it to pull some of the fresh intake charge when the transfer port suddenly opens. I don't want ANY pressure in the combustion chamber when the transfer port opens. Also the crankcase will be positive as the piston is coming down so there will be some pressure there to assist.
Obviously this is not possible on an oddy porting. The stroke is to small I think. I am just wondering the theory on this current huge overlap of our current porting.
