400ex QUESTION!!

I was wondering how much better my 406 ex would work that has a few small mods. I want to port and polish it. How big of difference will it make?

I don't see an exhaust in your list of mods???????

Stuff like porting will only gain you a little, and if it isn't done right sometimes it can do more harm than good.
