RE: hi po ryobi?

thanks for responding .i do intend to get the book on two stroke tuning, to give me a better understanding of what im looking for . but getting back to what you were saying ,if my base gasket is.020"thick and i remove it ,in order to restore the intake and exhaust timing i would need to cut .020"from the top of the piston at the exhaust port location on a 45degree angle,
and cut .020"from the piston skirt at the intake port location (or at the transfer port location on a reed valve engine ) to restore intake and exhaust timing to stock setting? and all of this piston cutting is just to try out the comppresion increase
and intake\exhaust timing changes ? hopefuly i am corect in understanding this much.
