It would depend on who did the porting and how much of a clue they have to what they are trying to accomplish. The polishing and av gas are a waste of time.

one million!

seriously, spend time learning how to corner better, then work on your jumping, then worry about the straight line speed. Also, if you are going to dump some jingle into your bike, start with cleaning up the jetting then get some suspension work done. You'll be amazed at how much better the bike will be.

what could I do to get a little more jam top keep up with 250 4 strokes

You could get a 250 4 stroke, seriously a 125 gets eaten alive by the 250F's so you could spend endless cubic $$ and you are not going to keep up with a 250F unless you are a vastly superior rider to the guy on the 250F.
