Eh ?
As mentioned before, the real stuff about 2-stroke tuning:

You would be amazed what you can get from a N21-3T if you just copy all the timings from a RX21, It can realy boost an 150 dollar engine up to the performance of a 400 dollar engine. This engine has nothing to do with a stable production but only lowered specs by design to allow the higher prices of more ports and faster engines.

Does that say something about your engine or the performance of the drivers?
Beating a NT1 with a simple Tamiya I would say it is a driver issue.

A rough surface creates a better mixture what will result in a better combustion so no polishing is needed.

We are not up to destroying you, only to wake up people (and you) what flowing realy does.
