port polishing has been discussed before... all port polishing is good for is eye candy and shelf queens.

If you think there is honestly a difference between polishing ports on a 2 cycle and ports on a 4 cycle... i question your skills as a modder.

When porting... or grinding or doing whatever work to a sleeve, everyone knows its best to emulate the scuffed finish that the engine initially came with.
