Zenoah Porting

You may be interested in my article on the nuts and bolts of Zenoah porting in the latest NAMBA Propwash. It contains tables of port distances from the top of the stroke as well as calculation methods for porting "slugs". The theory behind port timing was explained in the previous Propwash.

Thanks. My goal with these articles is to try to get a new generation of engine builders to try to roll their own.
