Polishing things on two stroke...

[padly1995]

Hello,
soon I will start with my graduation project.
I will be working on my Aprilia rs50 am6 two stroke engine.
I will install 70cc piston and cylinder, but I must do something that will take 22hours, so just installing the piston and cylinder won`t be enough.
Together with all other things that I will do I`m thinking of polishing things.

I have few questions about it, because I found mixed opinios on internet.
1.Can I polish the carburator, intake manifold or will this cause loss of the flow?
2.I`ve read that polishing intake ports is bad, because it needs little bit of texture on it, is this true?
3.Can I polish the crankcase or it needs texture on it also?
4.I know that I can polish exhaust port, correct me if I`m wrong?
5.Does polishing tranny case has any benefits?
