the smaller you go, the more top speed you will have. just don't go too small so you fry your engine. the more motor you have doesn't always mean a larger mainjet. however, more fuel can be pulled through that same mainjet sometimes because of the more powerful motor.

Most common mistake people make is that they need to go so much bigger... Most things you do to make anything just a little better than stock will more than likely be happy with proper jettings on a stocker for your area. Your engine doesn't like too much gas just like it doesn't like to little...
