Ok i have searched the seach gone to the web pages but my questions still haven't been answered. I am planning on street porting my 12a franken rotor housings while i have it apart. here's my question i have ported a "normal" motor before but have not done a rotary before. Do you use the same metod of placing the intake gasket on the housing and just grinding the material out untill the holes are the same size of the holes on the gasket? Or am i way off? what else is involved in this process? Any help is greatly appreciated.

Go to Racing Beat's web page and look up porting there. You actually have take the engine apart to port it.

Also, according to Yaw's web page, you shouldn't port the intake ports on the outside of the engine, something about messing up the flow characteristics and losing power, not gaining power.
