nickerbocker - got any photos of the new cylinder? Im interested in seeing how it turned out. and when you said you made 2 new ports, do you mean like the boost ports that only go into the cylinder part way or full blown ports?
ShaneB - Ive heard both. I was talking to my dad about it, and he said when he used to race motorcycles that the different teams would either leave it rough or polish it. They said if it rough it atomizes better. the others said if you polish it, theres less friction which equals better flow and more power. He ran both and said he couldnt tell a difference.
